dc.description.abstractIncreasing oil prices and tightened environmental regulations has more and more pushed the aviation industry to focus research on the optimization of aero engines. One of the more promising technologies is the open-rotor engine, which in essence is a compromise between the good fuel economy of a turboprop and the speed and range of the turbofan. If realized in commercial aviation, the open rotor engine promises lower fuel consumption and hence less environmental impact from emissions. This concept is however still in an early design phase and thorough studies will need to be performed in order for the open rotor concept to be able to compete with the conventional aero engines of today. As a step in the open-rotor development process, two research engineers at GKN Aerospace Engine Systems have come up with a new propeller concept for the open-rotor engine, involving so called box-bladed propellers. This concept can theoretically reduce the drag which is induced from the tip vortices created at the tip of conventional propellers. If the box-bladed propeller concept also performs satisfactory during engine operation in terms of transonic shocks and noise levels, they might well be better alternative than the conventional propeller. This thesis has been part of a design and experimental project carried out during the fall of 2012 at GKN Aerospace Engine Systems in collaboration with the department of Fluid Dynamics at Chalmers University of Technology. The aim of the thesis work has been to develop a method for geometric, aerodynamic and mechanical layout of an arbitrary box-bladed propeller for use in small-scale model testing. The method has been developed using elementary theory of propellers, using basic aerodynamics and structural design approaches. The thesis work has resulted in a MATLAB-based design code from which a couple of propellers have been developed, analyzed and manufactured by means of Rapid Prototyping technology. The design method allows for easy changes on preliminary geometries, together with a basic aerodynamic analysis and mechanical assessment.
