Method for the Prediction of Performance of STOL High Lift Systems near maximum Lift Coefficient

摘要

Potential flow and boundary layer methods are identified and developed for the analytic calculation of the performance of lift systems with significant flow separation. Particular emphasis is given to the use of the presented methods in the calculation of the flow field for a single airfoil in demonstration of their capability. A procedure for application to multiple element high lift systems is indicated. Special consideration is given to the representation of turbulent separating boundary layers and an empirical computational procedure has been developed where none had previously existed. The work presented herein provides a thorough basis on which to develop an accurate computer simulation model of high lift systems with significant flow separation. (Author)
