Some of you would probably remember the Davis Cold Jet from the late 70's.
I really think this design type could be explored again, especially with the lightweight
materials available today which weren't around 40 years ago
"D 340 Cold Jet
The Davis D-340 Cold Jet was a single staged high-pressure ratio axial flow compressor driven by
an internal combustion engine. Its maximum rpm was just over 18,000. The maximum tail pipe
velocity was just over 500 mph. The rotor blades were stainless steel and made to a tolerance
of .005 inches, with 350 hp, at 18,000 feet, it would be able to reach 300 mph."
