A turboshaft engine NMPC scheme for helicopter autorotation recovery maneuver
Aerospace Science and Technology, 2018Abstract Fast response for turboshaft engine plays an important role in shaping sound helicopter maneuver ability during some typical violent maneuvers like autorotation power recovery. An engine NMPC (nonlinear model predictive control), integrated with flight predictive information, is proposed to obtains better engine response speed and reduces ...

Some Aspects of Turboshaft Engine Installations in Multi-engined Helicopters
The Journal of the Royal Aeronautical Society, 1964In projecting future turboshaft engines for helicopter appUcations the engine designer is faced with the problem of selecting the size of engine to meet the likely size, configuration, performance and economic requirements of future helicopters. It is also desirable to meet as many different helicopter applications as possible with the same basic ...

Multi-objective optimization and system evaluation of recuperated helicopter turboshaft engines
Energy, 2020Abstract Targeting higher efficiency and lower emissions, the employment of recuperators in helicopters is well recognized as an attractive technical strategy to enhance the operational capabilities. Primary surface recuperator (PSR) is proposed for such applications, as its favorable characteristics of good heat transfer performance and compact ...

Performance of a Turboshaft Engine for Helicopter Applications Operating at Variable Shaft Speed
ASME 2012 Gas Turbine India Conference, 2012An 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. To this purpose, three off-design flight conditions were simulated and engine performance obtained with ...

Simulation of the Transient Response of a Helicopter Turboshaft Engine to Hot-Gas Ingestion
Volume 2: Controls, Diagnostics and Instrumentation; Cycle Innovations; Electric Power, 2008Hot-Gas Ingestion (HGI) to the engines can potentially occur when a rotorcraft or a VTOL/STOVL fixed-wing aircraft is operating in close proximity to the ground. Especially for helicopters, due to the rotor downwash hot exhaust gases get recirculated into the engine inlet. Similar conditions may also occur due to the ingestion of hot exhaust gases from

A novel neural network-based analytical system has been developed for classifying helicopter turboshaft engine operating modes during flight operations. This system utilizes a neural network architecture comprising an input layer with three neurons, two fully connected hidden layers, and an output layer with two neurons.
