On transonic flow models for optimized design and experiment

In the paper the near sonic flow theory for flows with small perturbations to sonic parallel flow is developed. This theory stands on the basis of potential flow of a compressible fluid and enables to receive an exact solution of the flow parameters past transonic cusped airfoils and their geometrical description. Generated airfoil shapes are tested using CFD ANSYS Fluent code to validate the results. Obtained numerical results from all-round commercial code show good accordance with the theory and confirm their value for future work in transonic design.
