This thesis will describe the works had been done by the author in the Flying Crane
aircraft group design project and the new design of a novel swing arm mechanism
which 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 of
group design project conducted by China Aviation Industry Corporation I (AVIC I) and
Cranfield University. At the end of the group design project, parameters such as take-off
and landing distance, trailing edge flap type and deflection in take-off and landing
configuration of the Flying Crane concept have been determined. These parameters are
design input of the novel trailing edge high lift device mechanism for this aircraft
concept.
The idea of this innovative mechanism comes from the research achievement of a
previous MSc student, Thomas Baxter, which applied swing arm mechanism into a
passenger aircraft's leading edge slat. This thesis applied this idea to trailing edge flap
and modeled the mechanism on CATIA software to yield a kinematic simulation for the
purpose of check motion trail and force transfer in this mechanism. Relevant works
such as actuation, mass and stress analysis are also involved.
As the result of this research project, it was found that swing arm mechanism trends to
require relatively small fairings for supports and attachments due to its high stowed
space utilizing efficiency. Initial mass estimation carried out in this thesis also indicates
that the new design takes advantage in terms of weight comparing with traditional
trailing edge flap mechanisms. Thus. swing arm mechanism is supposed to show great
competitive potential for commercial airliner's trailing edge flaps after further analysis
has been done in the detail design phase.
