fonak #67870 Laikus vagyok, de itt pl. az ez elég szakmai cikknek tűnik az UCAV-okról , bár nem mostanában íródott. :)
"No longer limited by human physiology, the UAV propulsion and airframe can now be designed beyond the 10g regime, to the theoretical limit of 20g where current turbines go out of round due to centrifugal forces."
"Hypersonic UAVs may be contemplated – besides having a higher thrust-weight ratio and reduced aerodynamic drag, they do not need the pressurisation and temperature shielding required to accommodate human beings."
"The Pulse Detonation Engine (PDE) under development by NASA represents a quantum leap in propulsion technology. This is an airbreathing, intermittent combustion jet engine that relies on a travelling detonation wave for the combustion and compression elements of the propulsive cycle. Capable of a range of speeds from Mach 0 to 3, it allows for a very high dash speed (supersonic) to the target area, a long loitering time at the target area and is efficient at low speed. The mechanical simplicity of this engine provides low cost and high reliability. In tandem with its industry partners, NASA expects to demonstrate a developmental PDE in 2005, with full-scale, operational engines available in 2009 (Marshall Space Flight Center, 2002)"
Ezzel a PDE-vel, úgy tűnik felhagytak, de létező elképzelés volt. Persze sok minden más is:)
