Abstract:

The Aircraft Regression Model ARM Task has explored modification of the Boeing Turbine Engine Variable Cycle Selection Airplane Response Engine SelectionTEVCSARES procedures by decoupling the representation of specific propulsion systems and the detailed mission definitions from the overall surface fit representations of the aircraft. Detailed comparisons between the RSTEPARM techniques developed herein and another available technique for aircraftengine design refinement are provided as the principal result of this program. All objectives of the RSTEPARM effort were attained. A simplified mission performance computer program was developed and tested in the evaluation of two engine cycle concepts, one a turbojet and one a turbofan. The program was simplified by using regression models for airframe geometry, weights, and drags. The program is currently operational in both the Air Force and at two industry sites.
