Journal Article

Conceptual design of a distributed electric anti-torque system for enhanced helicopter safety and performance

Brunetti, Massimo; Nesci, Andrea; Bianchi, Nicola

2023 CEAS Aeronautical Journal

doi:10.1007/s13272-023-00681-y

The flexibility offered by distributed electric propulsion (DEP) has triggered in the recent years a variety of new aircraft concepts, showing a way to improve the overall efficiency, capabilities and robustness of the future air vehicles. In comparison, the conventional helicopter tail rotor,...

Sensorless motor control for electro-mechanical flight control actuators

Kowalski, Robert; Juchmann, Patrick

2023 CEAS Aeronautical Journal

doi:10.1007/s13272-023-00682-x

Electro-mechanical flight control actuators have become a viable option as a replacement for conventional hydraulic actuators in future more electric aircraft. A rotor angle measurement is generally required for field-oriented control of the electrical machine and usually obtained from a...

Numerical investigation of a Coandă-based fluidic thrust vectoring system for subsonic nozzles

Schwagerus, Nils; Stößel, Marcel; Krummenauer, Michael; Kožulović, Dragan; Niehuis, Reinhard

2023 CEAS Aeronautical Journal

doi:10.1007/s13272-023-00677-8

The numerical investigation of a novel subsonic thrust concept for fluidic thrust vectoring (FTV) of jet engines is the subject of this publication. FTV possibly offers advantages over conventional mechanical thrust vector control such as decreased complexity, mass and maintenance costs. The...

Experimental investigation of UAV rotor aeroacoustics and aerodynamics with computational cross-validation

Kostek, Anna A.; Lößle, Felix; Wickersheim, Robin; Keßler, Manuel; Boisard, Ronan; Reboul, Gabriel; Visingardi, Antonio; Barbarino, Mattia; Gardner, Anthony D.

2023 CEAS Aeronautical Journal

doi:10.1007/s13272-023-00680-z

The study provided a base of comparison of known computational techniques with different fidelity levels for performance and noise prediction of a single, fixed-pitch UAV rotor operating with varying flight parameters. The range of aerodynamic tools included blade element theory, potential flow...

A contribution to the investigation of acoustic interferences in aircraft distributed propulsion

Guérin, Sébastien; Tormen, Damiano

2023 CEAS Aeronautical Journal

doi:10.1007/s13272-023-00679-6

The objective of this work is to better understand the acoustic interferences created by distributed propulsion engines based on an approach that combines RANS simulation results for the aerodynamic prediction and analytical models to calculate acoustics. A multi-propeller configuration without...
