ENGR 100 – Final Rocket Report

Group Assignment:

The purpose of this report is to describe the engineering design process, analysis, and results from the rocket project.  The audience of this report is person who is interested in doing a similar experiment with rockets.

Report Requirements:

The following is a list of the minimum details that should be included in the report:

Front pages: (see final bridge report assignment for details).  

1.0 Introduction:  

Outline the main objective and project description.  Include the goals for the first rocket (prototype) and the different goals for the second rocket (redesign).  Finally let the reader know what sections are coming next in the report. An executive summary is NOT required.

2.0 Methods

In this section, briefly describe the "virtual" components testing and results. Then explain how you used RockSim software during the design process and whether or not it was helpful.  Also explain the different methods used for measuring height:

• Rocksim launch prediction, 
• average of angle measurements (height = dist * tan (theta)), 
• the altimeter

Use pictures and sketches where appropriate in your discussions.

3.0 Design Descriptions

Describe in detail the initial rocket and prototype rocket w/ payload section that you designed and built.  For each rocket, start with a short description of the rocket's parts and then identify how these designs satisfied your goals. It should be clear to the reader why you designed each part of the rocket the way you did.  Use subheadings (e.g. 2.1, 2.2, etc.) as necessary to clarify organization of this section. Include the following tables and figures (see below for more details):

** Make sure all tables and figures are professional - limit the number of decimal points, center and label each column of data, don't forget units!

Figures:

• RockSim diagram of each rocket including total length, location of center of gravity, center of pressure, and fins
• Graph from Rocksim for altitude vs. time graph (also includes velocity vs. time and acceleration vs. time)

Tables:

• List of Materials (parts, mass for each, and cost).  Include the payload and altimeter. Include totals in the last row of this chart.
• Results Table(s) - predicted height, height calculations for each method, and comments for each launch including weather/wind conditions and any additional details like "rocket flew at an angle, parachute did not deploy, etc."
• Class Scores Table - list the scores for the redesign rockets in the class (itemize for altitude, payload, cost and bonus/penalty).  Show both predicted height and actual height but only score the actual height.  Be sure to highlight your rocket. 

Some example figures are show below in Figures 1 and 2.

Figure 2. Example Altitude vs. time for prototype rocket

3. 0 Performance Discussion:

In this section, discuss the results of your rocket launches both virtual (in RockSim) and actual.  Explain any trends you found in the data and what you think they mean.  Explain how your rocket did relative to the class and why. 

4.0 Conclusion section:

Summarize the main points of the report and be sure to "respond" to the objective(s) outlined in the introduction.  Discuss h ow you would change your rocket design to achieve better performance and/or a higher score?

Appendix:

List each team member’s name and specific areas they contributed to this project. Include design efforts with Rocksim, building of prototype and final rocket, writing of this report and contributions for poster presentation.
