Extract

During the course of fundamental research into noise suppression on jet engines, the need for a jet system which embodies quick mixing has become apparent, one way of doing this is by the use of a long thin peripheral slot in place of the usual circular nozzle Indeed noise measurements on such a jet unit indicate a reduction such as to make the use of pressure jets on helicopters once more feasible from the noise point of view
