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.

Energy Science &Engineering, Volume 11, Issue 1, Page 410-429, January 2023., 2023 A numerical model of a rotating detonation combustor with a turbine cascade is established. Effects of blade profiles on the interactions between the shock wave system and turbine cascade are analyzed. Distinct wave system structures are formed by varying the blade profile and rotating detonation propagation direction.

Process for Turboshaft Engine Performance Trending
Annual Conference of the PHM Society, 2023 Turboshaft engines are ubiquitous in aerospace applications where high power and reliability are needed in a low-weight package. Most all helicopters incorporate turboshaft engines. All turboshaft-equipped aircraft have power assurance checks to ensure the engine can achieve the minimum specification for power.

Power Fan Design of Blended‐Wing‐Body Aircraft with Distributed Propulsion System
International Journal of Aerospace Engineering, Volume 2021, Issue 1, 2021., 2021 A blended‐wing‐body aircraft has the advantages of high lift‐to‐drag ratio, low noise, and high economy compared with traditional aircraft. It is currently a solution with great potential to become a future civilian passenger aircraft. However, most airplanes with this layout use distributed power, and the power system is on the back of the fuselage ...
