Unformatted text preview: Lab 1 – Design Parameters and Tradeoffs 9 Feb 06 Unified Engineering Learning Objectives • Get familiar with flight performance modeling and prediction • Get familiar with design parameters and tradeoffs Preparation • Study the lab notes document “Flight Power Relations” Lab Execution and Deliverables 1) Working in a group of 3–5, extend the “Pro & Con” list at the end of the lab notes document for the following design parameter changes: • Increase the wing aspect ratio AR • Increase the maximum operating lift coefficient CL with higher-camber airfoil • Reduce cd by using thinner airfoil • Reduce fuselage’s CDA0 by adding fairing material Explain the rationale for each Pro and Con with a brief argument. A few sentences and possibly some simple algebra should suffice for each. Consider the effects on both tmax and Vmax . 2a) Rank the design parameters in order of decreasing perceived importance for tmax 2b) Rank the design parameters in order of decreasing perceived importance for Vmax Include the parameters given at the end of the lab notes document in this list. Two written pages should be sufficient to report your findings. Suggested teamwork process: i) Individuals make preliminary lists of pros and cons during preparation ii) Team meets and collates all these, agreeing on a rank ordering iii) Team splits work if possible to document their final result 1 ...
