Abstract

This paper presents results from a joint research effort of NASA Dryden Flight Research Center and the Institute of Flight Mechanics and Flight Control of the Technische Universität München on flight path control problems of aerospace craft when flying at high speed. There is an effect which leads to an increase of path-attitude decoupling with increasing airspeed. Beyond a certain airspeed in the supersonic or hypersonic flight regime, there is a limiting effect according to which path-attitude decoupling does not deteriorate further. The path-attitude decoupling problems were subject of an experimental simulation program using the high speed simulation facility of the NASA Dryden Flight Research Center. Since the conventional path control technique is not adequate in case of the severe path-attitude decoupling at high speed an alternate control technique is considered in the paper. A special display instrumentation was developed and installed in the cockpit of the high speed simulator of the NASA Dryden Flight Research Center. Furthermore, results from flight tests in the high supersonic regime at Mach 3 are presented. The flight test results are from a SR-71 operated by the NASA Dryden Flight Research Center.
