Unconventional Propeller−Airframe Integration for Transport Aircraft Configurations

It is envisioned that the future generations of regional and short to medium-range aircraft employ a high level of propeller integration to achieve low-emission flight. The objectives of unconventional propeller installations include the enhancement of the airframe aerodynamic efficiency, increasing the propeller efficiency, improving cabin...

Aerodynamic and Aeroacoustic Interaction Effects for Tip-Mounted Propellers: An Experimental Study

Propellers can enable a significant reduction in energy use of future aircraft by offering a higher propulsive efficiency than turbofan engines. This is especially relevant for a new generation of (hybrid-)electric aircraft. However, the integration of propellers with the airframe remains a challenge, and leads to performance and noise penalties...
