Aircraft Propeller Performance

Propellers power a number of commercial and military airplanes (Dash8-Q400, ATR42, ATR72, C27, C130J, A400, etc.). They also power the great majority of light and general aviation airplanes. Thus, in spite of the advances in gas turbine engines, propellers are still ubiquitous in aviation. That said, propeller data are few and far between; with the exception of some very old data available in the technical literature, the modern propeller is virtually unknown. In fact, the modern propeller is an extremely sophisticated system of transport airplanes. The blade sections are designed for transonic Mach number operation; the blades are swept back in the azimuth direction to improve noise emissions and aerodynamic performance; propeller control is guaranteed with the so-called PEC (propeller electronic control), and its FADEC.
