Abstract : The use of a jet flap diffuser for recovery of ejector jet kinetic energy has been investigated in a two-dimensional experiment, utilizing an ejector which employs a Coanda inlet for ninety degree rotation of the primary flow. Performance is compared to a solid diffuser ejector of the equivalent power and channel width. The jet flap diffuser ejector appears to have an advantage over solid diffuser ejectors for the rapid application of additional thrust for control purposes, as well as for the utilization of engine power in the production of propulsive energy.
