AE 146 Orbital Mechanics

Spring Quarter 2003

Design Project Part II

Oral presentation June 4th in class

Paper report due June 6th at TAs office

For grading criteria, see link under design project

The total design project (parts I and II) consists of 20% of your total grade. No standard solution is available. You may assume values for any parameters you may need -- you need only to justify your assumptions.

Objective (Part II)

The objective of part II is to design a rocket and staging sequence that will take a payload mass, m*, of 250 kg to its final destination in GEO. Your rocket will conduct the maneuvers designed in Part I of this design project. In addition to this payload, you will receive another payload mass, m*' of 100 kg from the first rendezvous satellite in GEO that you will deliver to the second one that is 10 degrees in front of you.

Oral Presentation (worth 50% of your design grade) Wed June 4th in class

You will present a summary of your project in an 8 minute presentation. The summary presentation includes information from parts I and II and should be done in a powerpoint presentation with overhead transparencies. The goal of the oral presentation, is to convince your audience that your chosen scenario is the best. This is best done by comparing different scenarios and by justifying certain assumptions.

Written Report (worth 50% of your design grade) due Friday June 6th in TAs office before 5:00

Your project (both parts I and II) should be contained in a single type written project report (one report per group). The thrust of the report is to provide compelling evidence that your final design is best. To this end, you should also show results for other situations that you have calculated that for some reason described in your report are inferior to your final design. Your report should contain the following (please keep it less than 15 pages):

  1. Title, name, date
  2. Abstract (less than one page)
  3. Introduction
  4. Design Method, the basic equations
  5. Calculation results and analysis. Present all your results in neat graphs, discuss the results and justify your choice of design parameters (dont just attach graphs and not explain them! you must also interpret them).
  6. Summary of your parameters. Conclude by summarizing in a few sentences your design methodology and whether you have achieved your design objective.
  7. References
  8. Appendix. Attach your computer program at the end of the report.
