Mechanical Engineering Aspects of Helicopter Design

Proceedings of the Institution of Mechanical Engineers, Part D: Transport Engineering, 1985
The work of the early pioneers which led to the evolution of the current helicopter configurations is briefly reviewed. The major mechanical elements of the helicopter are then identified: the engine, transmission and blades analogous to the engine, transmission and wheels of a road vehicle.

Research on dynamic modeling and performance analysis of helicopter turboshaft engine's start-up process

, 2020
It is a vital precondition that the aeroengine start-up quickly and successfully to ensure a safe flight, but the engine start-up process is a very complex non-equilibrium, non-linear aerothermodynamics process.

A Test Plant for Helicopter Engines

The Journal of the Royal Aeronautical Society, 1957
This Note describes the design and construction of a “ Tilting Test Bed ” for helicopter engines for Alvis Ltd., for which some onerous requirements were laid down (Fig. 1). The most important of these were that:—(i)Readings of engine torque and b.h.p.

The Licensing of Helicopter Maintenance Engineers

The Journal of the Helicopter Association of Great Britain, 1953
I should like to commence by referring to the remarks made during the all-day discussion on Helicopter Maintenance organised by your Association in co-operation with the Society of Licensed Aircraft Engineers, which was held on 21st October, 1950 Reference was then made to the practical difficulties of drafting the requirements for helicopter licensing
