A flexible method for the off-design analysis of SST by D. Bos

By D. Bos

Plane layout 1 (1998) 13—24

This paper offers a versatile and comparatively quickly analytical strategy to perform the off-design research of a powerplant set up for a supersonic delivery airplane (bypass engines). The approach doesn't impose any constraints at the working issues of the generators (like, for example, requiring them to stay choked), other than these similar to genuine actual obstacles, similar to bounds at the compressor go out temperature and the turbine access temperature. the results of the approach is a unmarried, closed-form expression that yields an off-design working aspect of the engine at a given Mach quantity, altitude and low-pressure turbine strain ratio.
