Parametric Modeling and Optimization of Advanced Propellers for Next-Generation Aircraft

As traditional fossil fuels become scarcer and more attention is given to environmental impact of the combustion of fossil fuels, for next-generation aircraft, the focus of development will mainly be on reducing fuel consumption. Open rotor engines have the advantage over conventional turbofans that they are expected to perform 25% to 30% better...

Wing Optimisation for Tractor Propeller Configurations: Validation and Application of Low-Order Numerical Models Adapted to Include Propeller-Induced Velocities

Even though propellers are the oldest form of propulsion, they are still a popular choice for unmanned aerial vehicles (UAVs) and passenger aircraft in certain market segments. If the propellers are mounted on the wing, strong propeller-wing interactions alter the aerodynamic efficiency of the aircraft. Using low-order numerical models, it is...

Unsteady Pylon Loading for Pylon-Mounted Tractor Propellers

Pylon Wake Control Using Steady Blowing: A Numerical Study

Sensitivity of Pusher Propeller Performance and Noise Emissions to the UpstreamWake Characteristics: An Experimental and Numerical Study

Open rotors are considered to have the potential to improve the fuel economy of aircraft significantly by improving the propulsive efficiency compared to the current generation turbofan engines. One of the possible configurations for the open rotors is the aft fuselage mounted contra-rotating pusher propeller. The aftfuselage mounted contra...

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...
