Horizontal Tailplane-Tip Mounted Tractor Propeller Interaction Effects

Advanced propeller propulsion systems potentially provide a significant reduction in fuel burn compared to traditional turbofans. An alternative to the conventional aft-fuselage mounted pusher layout is the horizontal tailplane-tip mounted tractor propeller concept. The aim of this thesis is an experimental investigation of the aeroacoustic and...

The Effects of Pylon Blowing on Pusher Propeller Performance and Noise Emissions

Growing concerns about the environmental impact of aircraft operations and increasing fuel prices have led to the demand for more fuel-efficient aircraft. One of the technologies with the potential to offer a significant reduction in fuel burn is the open rotor engine. However, the noise emissions of such engines are higher than for turbofans,...
