Tailless system control of jet aircraft

Abstract

Abstract PURPOSE:To perform tailless system control of jet aircraft by utilizing the jet exhaust nozzle flow and the relevant flow in the proximity of jet aircraft to use the jet flow both for propulsion and directional control through a guide damper, a grid, a tube, etc. CONSTITUTION:In order to control the direction of jet aircraft through a tailless structure, a single stage horizontally movable grid damper 5 in the vicinity of an exhaust nozzle 2 is used for lifting/lowering around a damper shaft 7 through a jet flow movable up and down while a double state vertically movable grid damper 6 is movable to the right and left around the damper shaft 7 to use the jet flow in the right/left direction. The jet flow 8 at the exhaust port 1 will lift/lower at the section 3 while propel to the right/left at the section 4 thus to serve as a rudder at the tail of conventional jet aircraft. Heat-resistance material such as carbon fiber, ceramic, titanium, etc. is employed especially at the hot portion in the jet stream and replaced in early time to achieve safety.
