ABSTRACT:
A cylindrical discharge manifold for an electrostatic gas-dynamic discharge ystem in a helicopter comprising four symmetrically positioned air outlets set in the end of a tubular manifold casing which protrudes out from the helicopter fuselage. The outlets connect to a central high-velocity air-stream inlet pipe in the casing by way of a plurality of air passages extending radially outward from the central inlet pipe. This manifold design insures a symmetrical air distribution, significantly reduces drag pressure on the aircraft, and obviates the requirement for "Y" air hose connections.
