Our primary focus is the slowed-rotor compound aircraft, a vertical takeoff and landing aircraft that uses the rotor for takeoff and landing, and a small, efficient wing for high speed flight, up to 500 mph, all with much less complexity than a tilt-rotor or other vectored thrust vehicle. We successfully demonstrated the slowed rotor concept with the CarterCopter Technology Demonstrator (CCTD), the first and only aircraft to reach mu-1

Yay! Bring back Little Nellie!

not all propeller planes would work in the cloud of volcanic ash, only piston prop planes because these do not suck in air like the turbo prop planes. Turo prop planes work on exactly the same prinliciple as a jet engine except that the force is used to spin propeller instaed of thrust

Where do they get the air they use to burn the fuel to create the little explosions that move the pistons up and down?
