We study noise generation at the blade tips of propellers designed for future electric aircraft
propulsion and, furthermore, analyze the interrelationship between noise mitigation and …

The momentum transferred to the fluid by a running propeller contains not only the desired
axial component but also a rotational component that does not contribute to the propeller …

Helicity is an important quantity that represents the topological interpretation of vortices;
however, helicity is not a Galilean invariant. In this study, VR helicity density (H VR) is …

A numerical investigation of a propeller with swirl recovery vanes, for which experimental
data exist, is performed. A second swirl recovery vane geometry, with shorter vanes to avoid …

Swirl-recovery vanes (SRVs) enhance propulsive efficiency by converting the rotational
kinetic energy in a propeller slipstream into additional thrust. This paper discusses the …

Propeller aircraft are widely used in general aviation. The rotating propeller has a strong
effect on the aerodynamic performance of the wing. This paper uses an actuator disc to …

桨扇-恢复旋流叶片(swirl recovery vane, SRV) 结构因其相对对转桨扇结构较为简单的传动机构
, 较弱的叶尖干涉以及能够为推进系统带来推进效率增益而重新受到关注 …

Purpose Pusher configured turbo-prop aircraft receive inadequate ram air cooling due to the
lack of propeller slipstream, particularly during ground operations. However, flow …

This thesis is written as the final part in the fulfillment of the Master of Science degree in
Aerospace Engineering. After my bachelors, I chose Flight Performance, which fully gratified …

The aim of this study was to investigate the action mechanism of the rotor–stator interaction
(RSI) in the transient flow field and hydrodynamic noise field of the guide vane in jet …
