Optimal Aircraft Design Methods
Abstract
The objectives to be pursued under this grant were to conduct analytical and applicational oriented (especially to aircraft industry) study of D-optimal design. The analytical study was aimed, partly, at answering questions such as: How does D-optimal design fare with respect to such properties as the uniqueness and orthogonality of the design, confounding of effects, interactions between the variables for linear and quadratic responses? The purpose of the application oriented effort was to demonstrate the application of the analytical results obtained to a typical Ground Attack Mission Profile and, independently, to a three-dimensional design space to select input conditions for an aircraft sizing program. The computer-aided D-optimal Design Program was supplied to the Design group at Flight Dynamics Laboratory, Wright-Patterson Air Force Base, with the request to run the program and obtain the simulated values of the various responses so that further statistical analysis and a sensitivity analysis on the performance functions in a region of aircraft designs encompassing the optimum combinations of engine/airframe variables could be carried out and the validity of the theoretical results could be verified and confirmed.
