Turbojet vs Turboprop On regional routes turbo propellers are the most efficient engines burning twice less fuel than turbojets, because they have a different propulsion system from the turboprop: the energy created drives a propeller in return. Because of the large diameter propeller, they require...

S Antas,T Chmielniak - 《International Journal of Turbo & Jet Engines》 被引量: 1发表: 2008年 Component-based exergetic measures of an experimental turboprop/turboshaft engine for propeller aire rafts and helicopters In this paper, component-based exergetic assessment is presented for an experimenta...
Prop planes are available in single & twin engine configurations, and unlike piston driven props, are powered by a jet engine which offers higher levels of performance, reliability, and fuel efficiency. They’re frequently chartered for short flights between major destinations including as New York ...

The electrical drive is composed by the following parts: (1) High power density propulsion motor: due to the high power density and high efficiency, permanent magnet motors are the most suitable motors for the application; in order to increase the reliability, this motor can be realized in ...
