Analysis of Helicopter Turboshaft Engines

Abstract

Significant improvement of helicopter engines, which has embodied mainly in power weight ratio, thermal cycle efficiency, specific fuel consumption, together with reliability and maintainability, of course, has influenced the technical-tactical parameters of helicopters. This fact makes it well worth examining this field. In this paper I introduce the evolution of helicopter turboshaft engines, review the specialities of their operation, the most important producers and types. Through statistical analyses I display, what kind of performance parameters the helicopter turboshaft engines had in the past and have present days.
