Research to understand, evaluate, analyse and exploit aerodynamic designs, both basic and unsteady, using CFD code application in conjunction with experimental data as appropriate, on fluid dynamic problems, relating to rotorcraft, stealthy weapon designs, part aircraft configurations such as intakes, afterbodies, weapons, weapon carriage and release systems, and high lift systems. Also includes associated predictive modelling and assessments based on wind tunnel testing. Includes work on applied aerodynamics; prediction and measurement techniques, development/validation/application of semi-emprical codes. Modelling stores carriage loads and release trajectories, drag prediction. Also includes research on relevant parts of aerolastics and aerothermodynamics disciplines.
