Intelligent Method of Identifying the Nonlinear Dynamic Model for Helicopter Turboshaft Engines. [PDF]

Sensors (Basel)
This research focused on the helicopter turboshaft engine dynamic model, identifying task solving in unsteady and transient modes (engine starting and acceleration) based on sensor data. It is known that about 85% of helicopter turboshaft engines operate in steady-state modes, while only around 15% operate in unsteady and transient modes.

Energy and Exergy Analysis on a Waste Heat Recovery Module for Helicopters

IEEE Access, 2021
The exhaust of turboshaft engines contains a big amount of waste heat but does not provide propulsion power to the helicopter. Reusing the heat can increase fuel efficiency and reduce carbon emissions of the engine.
