Abstract
A nozzle for use on opposing ends of the rotor of a jet powered tri-mode aircraft is disclosed. The nozzle includes two thermally-controlled doors, which are moveable between an open configuration where hot jet engine exhaust is vented therethrough to propel the rotor in a helicopter mode, and a second closed configuration where the two doors are tightly sealed to provide a stable aerodynamic surface for the rotor when the jet powered tri-mode aircraft is operating in an airplane mode. The two doors are thermally-activated by an internal surrounding temperature, such that they remain open by the hot jet engine exhaust passing thereby in the helicopter mode, and remain shut by resulting cooler air when the hot jet engine exhaust is not routed by the two nozzle doors.
