Computing Jet-Exhaust/Crossflow Interactions

JETPLT and JETBOD programs developed to predict velocity and pressure induced by subsonic jets exhausting into subsonic free stream. JETPLT predicts pressures induced on infinite flat plate by jet exhausting at angles to plate. JETBOD, in conjunction with panel code, predicts pressures induced on body of revolution by jet exhausting perpendicularly to surface. Programs used to investigate interactions between jet exhausts and crossflows in vertical/short-takeoff-andlanding aircraft shifting from hover to forward flight, where inducedpressure loading leads to reduction in lift. JETPLT/JETBOD written in FORTRAN 77.
