Title:
VECTOR ENGINE HAVING RUDDERS
Document Type and Number:
WIPO Patent Application WO/2017/121114
Kind Code:
A1
Abstract:
A vector engine having rudders. A horizontal rudder (3) and a vertical rudder (7) processed with a heat-resistant material having a high technical specification are installed at a jet nozzle (2) of a jet engine. By adjusting angles of control surfaces of the horizontal rudder (3) and the vertical rudder (7), the present invention provides the effect of changing a thrust direction of the engine and realizes a multiple-vector thrust of the engine. The horizontal rudder (3) or the vertical rudder (7) are both designed to be composed of two symmetrical parts which, when not in use, can rotate to two sides of the jet nozzle (2) respectively to be outside of a central region of air flows of the jet nozzle (2) so as to reduce a burning time of the rudders under high-temperature air flows. The horizontal rudder (3) or the vertical rudder (7) are designed to be disposed at an inner side of the jet nozzle (2), such that the horizontal rudder (3) or the vertical rudder (7) are fully covered by a tail pipe and shielded inside of the jet nozzle (2), thereby improving the stealth of a fighter aircraft having a stealth design. The vector engine having rudders is characterized by a simple structure and low technical difficulty.
