An Aerodynamic-Acoustic Design of an Electrical and Shrouded Tail Rotor

Aerospace industry innovations targets reduction of fuel consumption and noise emission. Electrical power-bywire
enabled technology address these challenges yielding lighter designs, increased operation flexibility and cost
reduction. With electric motors having variable rotational speed, constraints in design and optimization strategies
for rotor and propellers can be released. ln addition to conventional aircraft and rotorcraft, new concepts arise in
the urban air mobility or autonomous air delivery markets. Noise annoyance during manoeuvre and local
community noise concerns around heliports have to be addressed early by manufacturers. This research project
is intended to take on the challenge with the development of aerodynamic-aeroacoustic coupled optimization
methods for the design of quieter rotor and propellers. The objective of the partnership Bell Textron Canada
Limited and Optis Engineering is to develop a coupled aerodynamic-aeroacoustic optimization framework for an
electrical distributed anti-torque (EDAT) system to equip future Bell helicopters produced in Canada.
