Dear Gentleman, motorglider Stemme SB10, with rotax of 90 kg,can be improved by Subsonic Ramjet Hiller!!I made an aproach for 1000 newtons x 2 under every wing, and booster in the tail,De Laval CD knozzles for reaching ramjets start taking off.After many years research with pulsejets, DCR Ramjet and Scramjet are in my files,high stagnation temp. for scramjet makes me study reversible stirling engine criogenics cooler with expansion valves,helium or glycol, many options, xcramjet X43A, only concentrate hgh spots of 10000K somewhere,if you can helpme, I handle FEA to simulate,Hypersonc is the future,Best Regards Johann wegmann,White Eagle,Cobra Squadron,Chile.

There used to be an HJ-1 (the one with the big ruder) in the hangar at the San Jose State Aeronautics Dept. I wonder if it's still there?

Seems to me that the original machine had enormous potential as the basis for a very lightweight compound helicopter - one that would take off and land vertically under tip ramjet power, but cruise as an autogyro with much lower fuel consumption. Doing that would required making ramjets that were conformal with the rotor blade to make their drag acceptable in cruise, but this seems feasible.

This model served as the basis for the toy G.I. Joe helicopter I had as a kid in the early '60s (when all G.I. Joe accessories were based on some kind of real-life equipment). I remember thinking it was kind of silly looking, but I guess such a small, self-contained design was necessary to accomodate a foot high doll, in correct scale, within acceptable size and durability limitations for a toy. Something like a Bell-47 would have been too large and too complex (with it's strutwork tail) for such purposes
