The invention provides a method for aeroelastic tailoring of a
composite wing. The method for aeroelastic tailoring of the
composite wing comprises the steps that aeroelastic tailoring of the
composite wing is achieved by means of
aeroelasticity optimization, and solution of
aeroelasticity optimization is conducted according to a genetic / sensitivity-based
hybrid optimization method. The genetic / sensitivity-based
hybrid optimization method comprises the steps that (A) a group of individuals are generated randomly according to a
genetic algorithm; (B) performance evaluation is conducted on the individuals in the group one by one; (C) according to a user definition, whether sensitivity-based optimization is applied or not is judged; (D) whether the end condition is met or not is judged; (E) if the end condition is not met, a new generation of excellent individuals are generated; if the end condition is met, operation is ended. By the adoption of the method for aeroelastic tailoring of the composite wing and the genetic / sensitivity-based
hybrid optimization method, under the condition that multiple requirements for
flutter,
diffusion, inherent frequency, deformation,
aileron efficiency, strength, the flight load, weight and the like are met, tailoring design of the structure is achieved and optimized.
