A small point, but isn't the "action-reaction" lift referred to known as planar lift? Seems to me I've read figures as high as 30% for planar lift. Question: does planar lift account for the low speed effectiveness of fuselage strakes placed near the intakes of high performance a/c? I refer to types like the F-16, F-20, and SR-71 in particular. Is planar lift a significant factor in delta winged aircraft? The most extreme exaple I can think of here is the homebuilt Dyke Delta, which has a lot of wing area for its size. Fred Cordes
