Improved modeling of propeller-wing interactions with a lifting-line approach: Investigation of a suitable correction method to account for the finite slipstream height

Propellers have a high propulsive efficiency and can help in the reduction of fuel consumption of aircraft. For propellers which are mounted in front of the wing, the interaction of the slipstream with the lifting surfaces can alter the lift distribution significantly. In the use of modern optimization tools, fast and accurate analysis of the...

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...
