Fuel Weight Fraction Estimation for a Disk–Rotor Hybrid Aircraft Along an Optimal Flight Trajectory During Concept Design

International Journal of Aerospace Engineering, Volume 2025, Issue 1, 2025.
Owing to the transition flight of rotor/wing hybrid vertical take‐off and landing (VTOL) aircraft, the fuel weight cannot be estimated from empirical data during the conceptual design phase. This paper proposes a method for estimating the minimal fuel weight fraction (FWF) through a strategy of trajectory optimization under a given flight profile.

Power Level Influence on Architecture of Small Helicopter Turboshaft Engines [PDF]

Volume 2: Aircraft Engine; Marine; Microturbines and Small Turbomachinery, 1986
In the field of helicopter turboshaft engines, TURBOMECA is present in the range of 400 to 1 600 kW with four new engines, all under development. Naturally all these engines, born of a same general philosophy, have a pronounced ≪family likeness≫ from the general mechanical and aerodynamic point of view.
