An airborne system for vortex flow visualization on the F-18 high-alpha research vehicle

摘要: A flow visualization system for the F-18 high-alpha research vehicle is described which allows direct observation of separated vortex flows over a wide range flight conditions. The consists smoke generator system, on-board photographic and video systems, instrumentation. In present concept, entrained into low-pressure core, vortice breakdown indicated by rapid diffusion smoke. resulting pattern observed using images correlated with measured
