As far as we know, all work on externally blown flaps has been aimed at providing a basis for studies of the flight performance and handling qualities in respect of certain aircraft projects, one of which is the Dornier STOL transport aircraft. Theoretical work so far has only been possible in as much as the jet flap theory was extended to include any possible momentum distribution and finite jet thickness at the flap trailing edge. We know virtually nothing about the phenomenon of the jet flow spreading between the engine nozzle and the flap trailing edge. This question was studied on a simple wind tunnel model of an externally blown flap.
