Exergetic Investigation of a Turboshaft Helicopter Engine Related to Engine Power
SAE International Journal of Aerospace, 2020<div>Turboshaft engines, one of the classifications of the helicopters, combine the core engine and fan and consume fossil fuels. Emissions, produced by the fossil fuels, cause global warming and environmental pollution, such as ecological, human health. To improve helicopter capability, energy is the first point of improvement.

Three-Dimensional Sound Directivity around a Helicopter Turboshaft Engine
Journal of the American Helicopter Society, 2012Turboshaft engines can be the main source of noise due to a helicopter at takeoff. Some new silencing designs of the inlets and of the ejector were tested on a Turbomeca Arrius 2B2 engine in an open-air static facility. Intake and exhaust are not axisymmetric, and conventional directivity patterns of sound field on a horizontal arc of circle are ...
