Comparative Study of Helicopter Engine Particle Separators [PDF]
Journal of Aircraft, 2014 Particle separators are fitted to helicopter engine intakes to remove potentially harmful dust from the influent air. Their use is necessary in desert environments to eliminate the risk of rapid engine wear and subsequent power deterioration. However, their employment is concomitant with an inherent loss in inlet pressure and, in some cases, auxiliary ...
