The available reports on exhaust ejectors used as pumps or thrust augmentors are listed and a survey of the existing data is given. In this Note the general effect of the main variables on ejector performance is shown and theoretical and experimental ejector performances are compared. The data for estimating the basic exhaust thrust and the optimal exhaust nozzle area are considered and it is concluded that the thrust but not the nozzle area can be estimated adequately at present. Future theoretical and experimental work on ejectors is suggested, and includes, in the first instance, the development of a uniform theory of ejectors regarded as thrust and pumping devices.
