DESCRIPTION:Within the last decade there has been renewed interest in the 
 development of morphing aircraft structures which can undergo complex chan
 ges of configuration during flight. This was spurred in particular by the 
 announcement of the US Defense Advanced Research Projects Agency (DARPA) M
 orphing Aircraft Structures (MAS) programme. Many proposed concepts rely o
 n the use of compliant structures which allow smooth\, aerodynamically-eff
 icient profiles to be retained in all configurations. The use of topology 
 optimization techniques is well-suited to the design of compliant structur
 es\, as their behaviour can be unintuitive (particularly when the complian
 ce is not localized)\, and thus they are difficult to design by convention
 al methods.\n \nAn implementation of 'Load Path Topology Optimization' is 
 presented\, which is then applied to the design of an adaptive wing leadin
 g edge structure. It is shown that the use of topology optimization can as
 sist the development of feasible adaptive aircraft structures. A prototype
  model will be demonstrated.\n
