You can double-click the rocket's name in the main window, to enter information about your design in the Rocket Configuration window:
+
== Rocket Configuration ==
  
−
[[File:Rocket_configuration.png|thumb|400 px|left|The <em>Rocket Configuration</em> window for MacOS.]]
+
To build your first rocket, start OpenRocket, then double click the ''Rocket'' label at the top of the component tree to open the ''Rocket configuration'' pop-up window. OpenRocket allows you to name your design, identify the designer, make comments, and create a revision history.
−
[[File:Rocket_configuration_Windows.png|thumb|400 px|center|The <em>Rocket Configuration</em> window for Windows.]]
 
  
 +
The default design name is ''Rocket'', but that name can be changed, and a design name change also changes the name of the rocket shown on the component tree. So, rename your design and enter the designer, comments, and revision history information you desire.
  
−
It's a good idea to fill in this information when you start a new rocket project. Fill in the four fields (or you can leave all, except the <em>Design name</em>, blank if you wish), and click the <em>close</em> button. <br />

== Adding External Components ==
  
−
Notice there are three tabs in the top of the window. These tabs allow you to switch between the <em>Rocket design</em>, <em>Motors and Configuration</em>, and  <em>Flight simulations</em> windows. <br />
+
Now it's time to start putting together components to build the rocket design. The generally accepted way of putting together a rocket design is from top to bottom, from nose to tail.  So, we'll add the nose cone first.
  
 +
=== Selecting a Nose Cone ===
  
−
== The <em>Rocket design</em> window ==
+
With the ''Stage'' selected, click on the ''Nose Cone'' button and the ''Nose Cone configuration'' window will pop up. Then, select ''From database...'' to open the Choose component present window. From here, you can select from the pre-loaded parts database. Select the nose cone shown below, and click the ''Close'' button, then close the ''Nose Cone configuration'' window.
−
{{anchor|rocketdesignwindow}}
 
−
For the moment, let's focus on the <em>Rocket design</em> window. This window is organized in the following way: <br />
 
−
- in the bottom half of the window there is a large white space. This is where a 2D image of the rocket you are designing will appear. <br />
 
−
- in the top-left part of the window, the rocket's <strong>stages</strong> and <strong>components</strong> are shown. When you start a new project, the rocket contains only one stage (i.e.; the <strong>sustainer</strong>) but no components. <br />
 
−
- in the top-right part of the window, all the <strong>body components</strong> and <strong>fin sets</strong>, <strong>inner components</strong>, and <strong>mass objects</strong> that you can add to the rocket are shown. Notice that it's not possible to add all of these objects to the rocket at any particular stage of the rocket design. Exactly which components can be added when will be explained later in this guide. <br /><br />
 
  
−
Now let's have a closer look at the bottom half of the <em>Rocket design</em> window. When you add a component to your rocket, it will be immediately displayed, as shown below:
+
<table class="left">

 +
=== Adding a Payload Bay ===
  
−
Notice the <strong>rulers</strong> around the borders. These give you an idea of the dimensions of your rocket. <br /><br />
+
So that a few "appearance" can be demonstrated later, a payload bay will be added after the nose cone. To do this, with either the ''Stage''or ''Nose Cone'' selected, click on the ''Body Tube'' button and the ''Body Tube configuration'' window will pop up. Then, select ''From database...'' to open the Choose component present window. From here, you can select from the pre-loaded parts database. Select the body tube shown below, and click the ''Close'' button, then close the ''Body Tube configuration'' window.
  
−
As you can see, in addition to the appearance of your rocket, the <em>Rocket design</em> window also shows some other useful information as well. This includes the rocket's <strong>dimensions</strong>, <strong>mass</strong>, <strong>apogee</strong>, <strong>max. velocity</strong>, <strong>max. acceleration</strong>, <strong>stability</strong>, <strong>center of gravity</strong> (<strong>CG</strong>), and <strong>center of pressure</strong> (<strong>CP</strong>). <br /><br />

<table class="left">

In the top left-hand corner of the previous image there are two buttons: <em>Side view</em> and <em>Back view</em>. These allow you to visualize the rocket from two different positions. Next to these buttons you can find the <em>zoom-regulation commands</em> and then one <em>Stage i</em> button for each <strong>Stage</strong> in your rocket. Selecting/deselecting each of these allows you to include or exclude each stage from the picture. On the left of the previous image, you can also see a scroll bar that allows you to rotate the rocket up to 360°. <br /><br />
+
<br />
  
−
Finally, notice the drop-down list in the top right-hand corner of the previous image. This allows you to choose which of your <strong>motor configurations</strong> to apply to the rocket you have designed (more on this later). The image below shows how the bottom half of the <em>Rocket design</em> window appears after the rocket design has been completed.
+
=== Adding a Transition ===
  
 +
Transitions are most often used to connect body tubes with different diameters. But, a transition can also be used to connect two body tubes of the same diameter, as will be done here.
  
−
[[File:After_complete_design.png|thumb|1000 px|center|Bottom half of the <em>Rocket design</em> window after completing the rocket's design (taken from the <em>A simple model rocket</em> example design).]]
+
To do this, with either the ''Stage'' or ''Payload Bay'' selected, click on the ''Transition'' button and the ''Transition configuration'' window will pop up. The default ''Transition Configuration'' tab is the ''General'' tab. On this tab, change your entries in the circled areas below to match the entries shown. Then, click the ''Shoulder'' tab, and change your entries in the circled areas below to match the entries shown. Then, click the ''Close'' button.
  
 +
<table class="left">
 +
  <tr>

In this image, the rocket's <strong>body components</strong> and <strong>fin sets</strong> are represented with a continuous blue line; the rocket's <strong>inner components</strong> are represented with a continuous red line (the <strong>inner tube</strong> is also filled in with a grey background); and the <strong>mass objects</strong> are represented with either black or red dotted lines. It is also possible to customize the colour in which each part is represented, as will be shown later on. The image below shows how the top left-hand portion of the <em>Rocket design</em> window looks after the rocket design has been completed.
+
<br />
  
 +
=== Adding a Body Tube ===
  
−
[[File:Structure.png|thumb|397 px|center|Top left-hand portion of the <em>Rocket design</em> window after completing the rocket's design (taken from the <em>A simple model rocket</em> example design).]]
+
Now, do what you did to add the ''Payload Bay'', above, but select this body tube from the parts database:
  
 +
<table class="left">
 +
  <tr>
 +
    <th>Add a ''Body Tube''</th>
 +
    <td>'''[[File:11.04.01.Rocket_Build.Body_Tube.png|left|frameless|512 px|center]]'''</td>
 +
  </tr>
 +
  <tr>
 +
    <th>''Body Tube'' Added</th>
 +
    <td>'''[[File:11.04.02.Rocket_Build.Body_Tube.png|left|frameless|1028 px|center]]'''</td>
 +
  </tr>
 +
</table>
  
−
As you can see, the rocket's components have a tree-like structure: <br />
+
<br />
−
- the <strong>Rocket</strong>, called <em>A simple model rocket</em>, has only one stage: the <strong>Sustainer</strong>. <br />
 
−
- the <strong>Sustainer</strong> contains two <strong>body components</strong>:  a <strong>Nose cone</strong> and a <strong>Body tube</strong>. <br />
 
−
- the <strong>Body tube</strong> contains a <strong>fin set</strong> (in particular a <strong>Trapezoidal fin set</strong>), a <strong>Launch lug</strong>, three <strong>inner components</strong> (an <strong>Inner Tube</strong> and two <strong>Centering rings</strong>), and three <strong>mass objects</strong> (a <strong>Shock cord</strong>, a <strong>Parachute</strong>, and a <strong>Wadding</strong>). <br />
 
−
- the <strong>Inner tube</strong> contains an <strong>Engine block</strong>. <br />
 
−
This tree-like structure will be discussed further later in this guide. <br /><br />
 
  
−
The buttons visible on the left in the previous image have pretty straightforward functions. By selecting one of the rocket's components you can change its position in the list of components (but <strong>not</strong> its position in the rocket) by using the <em>Move up</em> and <em>Move down</em> buttons. You can also edit its characteristics (e.g., dimensions, material, mass, color used to represent it within the rocket) by using the <em>Edit</em> button--or you can delete it from the rocket completely using the <em>Delete</em> button. Notice that none of these buttons is active in the above image, since no component has been selected.<br /><br />
+
=== Adding Fins ===
  
−
You can also add an extra stage to your rocket by clicking the <em>New stage</em> button.
+
The bottom component are the fins. OpenRocket offers four types of fins, ''Trapezoidal'', ''Elliptical'', ''Free Form'', and ''Tube Fins''. For this design, ''Trapezoidal'' fins will be used.
  
−
== The <em>Flight simulations</em> window ==
+
With the ''Body Tube'' selected, click on the ''Trapezoidal'' fins button and the ''Trapezoidal Fin Set configuration'' window will pop up. On your default ''General'' tab, change your entries match the entries shown. Then, click click the ''Close'' button.
  
−
Now we have a look at the <em>Flight simulations</em> window, which you can access by selecting the <em>Flight simulations</em> tab in the top left-hand corner of the <em>OpenRocket main window</em>. Before designing your rocket or running any flight simulation, the <em>Flight simulations</em> window looks like this:
+
<table class="left">
 +
  <tr>
 +
    <th>Select ''Fin'' Type</th>
 +
    <td>'''[[File:11.05.01.Rocket_Build.Fins.png|left|frameless|1028 px|center]]'''</td>
 +
  </tr>
 +
  <tr>
 +
    <th>Select ''Fin'' Type</th>
 +
    <td>'''[[File:11.05.02.Rocket_Build.Fins.png|left|frameless|512 px|center]]'''</td>
 +
  </tr>
 +
</table>
  
 +
<br />
  
−
[[File:Empty_simulations.png|thumb|800 px|center|The <em>Flight simulations</em> window before designing the rocket and running any simulation.]]
+
Fins attach to another component, in this case the ''Body Tube''. As circled below, the fins are shown underneath the ''Body Tube'' on the component tree.
  
 +
<table class="left">
 +
  <tr>
 +
    <th>''Fins '' Added</th>
 +
    <td><br />'''[[File:11.05.03.Rocket_Build.Fins.png|left|frameless|1028 px|center]]'''<br /></td>
 +
  </tr>
 +
</table>
  
−
Notice that the bottom part of the window does not change when switching from the <em>Rocket Design</em> window to the <em>Flight simulations</em> window. Hence we only need to analyze the top part of the window. Here, most of the space is occupied by a currently blank space, where the technical details about your simulations will appear. Above this space there are five buttons, which allow you to <strong>program a new simulation</strong> (<em>New simulation</em>), <strong>edit a selected simulation</strong> (<em>Edit simulation</em>), for example by changing motor configuration or some atmospheric condition, <strong>run all the simulations you have programmed</strong> (<em>Run simulations</em>), <strong>remove the selected simulations</strong> (<em>Remove simulations</em>), or either <strong>plot or export some of the results of a selected simulation</strong>(<em>Plot/export</em>). (More on exporting simulation results in [[Rocket Analysis]].)<br /> <br />
+
<br />
  
−
The image below shows how the top part of the <em>Rocket Design</em> window looks after you have designed your rocket, programmed some simulations, and run them.
+
=== Adding a Launch Guide ===
  
 +
OpenRocket includes two styles of launch guides, ''Rail Buttons'' and a ''Launch Lug''. Because of the diameter of the body tube, a ''Launch Lug'' will be used for this design. As with fins, launch guides attach to another component, in this case the body tube.
  
−
[[File:Simulations.png|thumb|1000 px|center|The top half of the <em>Flight simulations</em> window after having programmed and run some simulations (taken from the <em>A simple model rocket</em> example design).]]
+
You should now be able to open the ''Launch Lug configuration'' window without assistance. So, open your ''Launch Lug configuration'' window, and change the specifications to match those shown below.
  
 +
<table class="left">
 +
  <tr>

Notice that five of the six simulations that have been run have a green tick on the left: this means that the simulation has been completed without any <strong>warnings</strong>. Conversely, if the simulation has generated some <strong>warning</strong> while being run, a red exclamation mark is shown (as for the third simulation in the image above). To find out more about the warning, mouse-over the simulation (without clicking) as shown in the image below.

The image below shows the options offered by the <strong><em>File</em></strong> menu, located in the top left-hand corner of OpenRocket's <em>main window</em>.

The function of each option in the <em>File</em> menu is pretty straightforward to understand: <br />
 
−
- <strong><em>New</em></strong> allows you to start a new project, without closing the project that is currently open. <br />
 
−
- <strong><em>Open...</em></strong> allows you to open a <em>*.ork</em> file that you have saved on your computer. <br />
 
−
- <strong><em>Open example...</em></strong> allows you to open one of the example projects (more on these later). <br />
 
−
- <strong><em>Save</em></strong> saves the changes you have made to a previously-saved project. <br />
 
−
- <strong><em>Save as...</em></strong> allows you to save the project you are working on to a new <em>*.ork</em> file. <br />
 
−
- <strong><em>Print/Export PDF</em></strong> opens a window like the one shown below (if you have already completed your rocket's design). From here you can select what to include in your print/PDF file; such as technical details of your rocket's components, templates of your rocket's fin sets, or even the design of your rocket. We suggest you try this option with one of the example projects to understand how each of these is represented when printing/exporting to PDF. More on printing and exporting to PDF in [[Rocket Analysis]].
 
 
<br />
 
<br />
−
- <strong><em>Close</em></strong> closes the current project (after asking for confirmation if there are unsaved changes). This will also exit the application if there was only one project open. <br />
 
−
- <strong><em>Quit</em></strong> exits the application, checking that you have saved all open projects.

−
[[File:PDF.png|thumb|431 px|center|The window that opens when <em>Print/Export PDF</em> is selected.]]
+
== Basic Views ==
  
 +
<br />With the airframe complete, you can view your design in either 2D (as above) or three 3D views. The most commonly used of which are ''3D Unfinished'' and ''3D Finished''<br />.

== The <em>Edit</em> menu ==

== Adding Appearance Settings ==
  
−
[[File:Edit.png|thumb|154 px|center|The <em>Edit</em> menu.]]
+
<br />When changing ''Appearance'' settings, it is best to be in the ''3D Finished'' pane so that you can see the changes that you are making. So, let's start by changing the view to ''3D Finished''.
  
 +
<table class="left">

These options are mostly the classic editing options: undo/redo some action (<strong><em>Undo</em></strong>/<strong><em>Redo</em></strong>) and cut/copy/paste/delete some element (<strong><em>Cut</em></strong>/<strong><em>Copy</em></strong>/<strong><em>Paste</em></strong>/<strong><em>Delete</em></strong>). We also have the following options: <br />
+
<br />
−
- <strong><em>Scale...</em></strong> opens the window shown below. Here you can choose to scale your rocket's size by some percentage (you can select from a range of 25% to 400%), starting from a specified dimension that can either be the one the rocket currently has or one you specify. By checking or unchecking the <em>Update explicit mass values</em> box, you can also decide whether or not the rocket's mass should be updated when scaling its volume.

The current User's Guide is very much a work in progress, any help would be greatly appreciated!
If you'd like to contribute something, just hit the 'Edit' tab at the top.



In this section we have a look at how OpenRocket is organized, by analyzing in detail the structure of the user interface. We will also briefly mention the Example projects that are accessible from the File menu. After reading this section you will have a thorough understanding of how OpenRocket is structured, and will be ready to start designing a rocket of your own. If you already know how this program is organized, feel free to jump to Basic Rocket Design, the next section.


The User interface[edit]

The OpenRocket user interface is divided horizontally into four sections, the Main Menu (green); the Task Tabs (black); the Rocket Design, Motors & Configuration, and Flight Simulation Pane (red), and the Rocket Views Pane (blue).

UI of OpenRocket divided into four

Main Menu[edit]

Menu Item Description
File
02.04.01.File Menu.png
 The File Menu is divided into five divisions by function, (1) file opening options; (2) file saving options; (3) import and export options; and (4) closing and (5) quitting options.
- New allows you to start a new project without closing the project that is currently open; you can have more than one project open at the same time. If you start a new project when you have not already started (made changes to) the current project, a new project will be opened and the empty project will be closed, leaving one project open.
- Open... allows you to open an *.ork file that you have previously saved on your computer.
- Open Recent opens a pull-down menu of recently opened filed from which you may choose one to reopen.
- Open Example allows you to select from and open an example project included with OpenRocket.
- Save saves the changes you have made to a project that you have opened or previously saved, without changing the current filename or location of the file.
- Save as... allows you to save the project you are working as a different filename and/or a different file location.
- Export as allows you to export the project you are working on to a different file format, such as a Rocksim 10 (.rkt) file.
- Save decal image allows you to save a decal image file used in your project (currently only the first decal). However, this option is not available until you actually add a decal to your project.

Task Tabs[edit]

The windows shown below utilize the A simple model rocket example included with OpenRocket.

Rocket Design
01.02.Rocket Design.Tab.png
The Rocket Design tab is divided into three sections, the component tree, component arrangement buttons, and component selection buttons. The components available in OpenRocket are divided into four classes based upon component function. These classes are assembly components, body components and fin sets (external components), internal components, and mass components (which include electronics and recovery components). Components are greyed out until it would be appropriate to add that component type. As components are added, you will see the component tree (on the left side of the window, grow with each component added. For a detailed description of each component, see Component Details.
Motors & Configuration
02.02.Motor-Configuration.Tab.png
The Motors & Configurations tab is where you select motors, recovery events, and stage timing. Motor configuration options include creating new configurations, renaming existing configurations, removing (deleting) configurations, and copying configurations. With a specific configuration selected, you may select (or select a different) motor, remove the motor, or select and reset the motor ignition timing. For more motors and configuration utilization details, see Motors & Configuration Details.
Flight Simulations
03.02.Flight simulations.Tab.png
The Flight Simulations tab is where you manage and flight simulations and flight simulation plots. From here, you can add new simulations, or edit, run, or delete existing simulations. Select a single simulation, and you can even plot and export the simulation results. For more details on how to use these functions, see Flight Simulations Details.

← Go to Main Menu


Rocket Views[edit]

The windows shown below utilize the A simple model rocket example included with OpenRocket.

The Top View, Side View, and Back View are line drawings, similar to a blueprint that shows all of the rocket components and the placement of those components. Almost all of your design work will take place in the top, side, and back views.
Top/Side/Back View
Getting Started.Rocket Views.Top View.jpg
Getting Started.Rocket Views.Side View.jpg
Getting Started.Rocket Views.Back View.jpg

The 3D Figure and 3D Unfinished view allow you to look through the rockets exterior to view many of the interior components. These views can help you more clearly see the relationship between the placement of different components inside the airframe.

Become Familiar with OpenRocket[edit]

For new users of OpenRocket, before attempting to create your own custom rocket design, it is strongly recommended that you become familiar with the OpenRocket user interface and generally accepted rocket design principles by opening and looking at how an example is assembled, making changes to the example, and understanding how to simulate flights. The example designs are found here:

The Basics of Using OpenRocket[edit]

Rocket Configuration[edit]

To build your first rocket, start OpenRocket, then double click the Rocket label at the top of the component tree to open the Rocket configuration pop-up window. OpenRocket allows you to name your design, identify the designer, make comments, and create a revision history.

The default design name is Rocket, but that name can be changed, and a design name change also changes the name of the rocket shown on the component tree. So, rename your design and enter the designer, comments, and revision history information you desire.

Adding External Components[edit]

Now it's time to start putting together components to build the rocket design. The generally accepted way of putting together a rocket design is from top to bottom, from nose to tail. So, we'll add the nose cone first.

Selecting a Nose Cone[edit]

With the Stage selected, click on the Nose Cone button and the Nose Cone configuration window will pop up. Then, select From database... to open the Choose component present window. From here, you can select from the pre-loaded parts database. Select the nose cone shown below, and click the Close button, then close the Nose Cone configuration window.

Congratulations, you've just added your first component.


Adding a Payload Bay[edit]

So that a few "appearance" can be demonstrated later, a payload bay will be added after the nose cone. To do this, with either the Stageor Nose Cone selected, click on the Body Tube button and the Body Tube configuration window will pop up. Then, select From database... to open the Choose component present window. From here, you can select from the pre-loaded parts database. Select the body tube shown below, and click the Close button, then close the Body Tube configuration window.

Add a Body Tube

Payload Bay Added
11.02.06.Rocket Build.Payload Bay.png


Adding a Transition[edit]

Transitions are most often used to connect body tubes with different diameters. But, a transition can also be used to connect two body tubes of the same diameter, as will be done here.

To do this, with either the Stage or Payload Bay selected, click on the Transition button and the Transition configuration window will pop up. The default Transition Configuration tab is the General tab. On this tab, change your entries in the circled areas below to match the entries shown. Then, click the Shoulder tab, and change your entries in the circled areas below to match the entries shown. Then, click the Close button.

11.04.02.Rocket Build.Body Tube.png


Adding Fins[edit]

The bottom component are the fins. OpenRocket offers four types of fins, Trapezoidal, Elliptical, Free Form, and Tube Fins. For this design, Trapezoidal fins will be used.

With the Body Tube selected, click on the Trapezoidal fins button and the Trapezoidal Fin Set configuration window will pop up. On your default General tab, change your entries match the entries shown. Then, click click the Close button.

Select Fin Type

Select Fin Type
11.05.02.Rocket Build.Fins.png


Fins attach to another component, in this case the Body Tube. As circled below, the fins are shown underneath the Body Tube on the component tree.

Fins Added
11.05.03.Rocket Build.Fins.png


Adding a Launch Guide[edit]

OpenRocket includes two styles of launch guides, Rail Buttons and a Launch Lug. Because of the diameter of the body tube, a Launch Lug will be used for this design. As with fins, launch guides attach to another component, in this case the body tube.

You should now be able to open the Launch Lug configuration window without assistance. So, open your Launch Lug configuration window, and change the specifications to match those shown below.
