Reading about the Avrocar, I am surprised the design was not taking up more recently. It’s kind of the jet equivalent of the quadracopter, in terms of its operating envelope. It seems like all the problems that Frost had back in the 50s could’ve been fixed with modern design tools and competitions fluid dynamics. Except for the inability to achieve high speed flight let alone Mach 3.3 which military was interested in. But I wonder about using the flying saucer design has more efficient drone or regional delivery system, as it has the efficiency of jet power with the mobility of a helicopter, and its short range and low speeds are not a concern in those applications. I hope some enterprising aeronautical engineering student at Calpoly parters with some compsci engineers at Stanford to take this up...
