Abstract:

This experimental investigation demonstrated the criticality of performing accurate full-scale engine exhaust simulations during model-measured VSTOL ground effects testing. The effects of varying the nozzle exit turbulence, total pressure distributions, and nozzle pressure ratio on the net and component ground-induced forces for two-, three-, and four-nozzle configurations with large blocking surfaces as well as a smaller, cruciform two-nozzle blocking surface more characteristic of a real aircraft planform were studied.
