Patent ID: 10071814

Abstract:
An exhaust arrangement is for an aircraft having sensing equipment and a front prop engine. An extension mounts on the underside along an edge of the fuselage to direct exhaust from the engine's exhaust pipes to a point to or past the sensing equipment typically exposed at the mid-section of the aircraft. An extension inlet mounts adjacent the pipe and defines a funnel or conical orifice not directly affixed to the pipe. One or more conductors for the extension then extend from the inlet to convey the exhaust to an outlet of the extension. Preferably, multiple conductors can be used with an expansion joint provided between them. The outlet preferably diverts exhaust away from the tail end of the aircraft. To mount the extension to the aircraft, several arrangements of supports including rods, lugs, angles, and the like hold the extension in vertical, lateral, and axial directions to the aircraft.
