Regression Simulation of Turbine Engine Performance/Aircraft Regression Model.

摘要

The Aircraft Regression Model (ARM) Task has explored modification of the Boeing Turbine Engine Variable Cycle Selection /Airplane Response Engine Selection(TEVCS/ARES) 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 RSTEP/ARM techniques developed herein and another available technique for aircraft/engine design refinement are provided as the principal result of this program. All objectives of the RSTEP/ARM 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.
