The application of gas turbine engines in helicopters is discussed. The work-ings of turboshafts and the history of their use in helicopters is brie y described. Ideal cycle analyses of the Boeing 502-14 and of the General Electric T64 turboshaft engine are performed.
Comparison of Helicopter Turboshaft Engines. Although they garnish less attention than their flashy jet cousins, turboshaft engines hold a specialized niche in the aviation industry. Built to be compact, efficient, and powerful, turboshafts have made modern helicopters and the feats they accomplish possible.
The present work conducts an elaborated investigation on previous development work of recuperated helicopter turboshaft engines, and followed by the relevance of accumulated experience, as...
Far beyond the airplane turboprop or turbofan engine, the helicopter turboshaft engine controls the main rotor speed and therefore directly affects the flight capability, safety and transient manoeuvers of the helicopter. The first part of this paper describes the main characteristics of the turboshaft engine with magnitude orders.
The TV3-117VMA-SBM1V turboshaft engine is intended for new helicopters or retrofitting existing helicopters. It maintains high power even in hot and high altitude conditions, improving helicopter performance. The engine's automatic control system allows takeoff power adjustment between 2,000-2,500 horsepower.
An off-design steady state model of a generic turboshaft engine has been implemented to assess the influence of variable free power turbine (FPT) rotational speed on overall engine performance, with particular emphasis on helicopter applications.
The Honeywell upgraded T55 propulsion engine offers helicopter pilots a reliable, time-tested engine that requires less maintenance due to a simple, rugged design created to withstand harsh environments.
