This thesis will describe the works had been done by the author in the Flying Craneaircraft group design project and the new design of a novel swing arm mechanismwhich can be applied in the trailing edge high lift devices for this aircraft concept.Flying Crane aircraft is a new generation commercial airliner concept as the result ofgroup design project conducted by China Aviation Industry Corporation I (AVIC I) andCranfield University. At the end of the group design project, parameters such as take-offand landing distance, trailing edge flap type and deflection in take-off and landingconfiguration of the Flying Crane concept have been determined. These parameters aredesign input of the novel trailing edge high lift device mechanism for this aircraftconcept.The idea of this innovative mechanism comes from the research achievement of aprevious MSc student, Thomas Baxter, which applied swing arm mechanism into apassenger aircraft's leading edge slat. This thesis applied this idea to trailing edge flapand modeled the mechanism on CATIA software to yield a kinematic simulation for thepurpose of check motion trail and force transfer in this mechanism. Relevant workssuch as actuation, mass and stress analysis are also involved.As the result of this research project, it was found that swing arm mechanism trends torequire relatively small fairings for supports and attachments due to its high stowedspace utilizing efficiency. Initial mass estimation carried out in this thesis also indicatesthat the new design takes advantage in terms of weight comparing with traditionaltrailing edge flap mechanisms. Thus. swing arm mechanism is supposed to show greatcompetitive potential for commercial airliner's trailing edge flaps after further analysishas been done in the detail design phase.
