Abstract:

The effect of duct geometry and primary jet characteristics on the level of thrust augmentation of conventional rocket motor jets, with conical nozzles exhausting into a stationary atmosphere, has been investigated. For a range of straight, cylindrical ducts with bell-mouth inlets, it is found that the duct thrust is primarily a function of duct length and primary thrust. Chamber pressure and nozzle conditions have little effect other than their effect on primary thrust.
