Aerodynamic layout of horizontally taking-off and landing two stage to orbit aircraft

Abstract

The invention discloses an aerodynamic layout of a horizontally taking-off and landing two stage to orbit aircraft. The aerodynamic layout of the horizontally taking-off and landing two stage to orbitaircraft comprises a first-stage aircraft and a second-stage aircraft, wherein the first-stage aircraft is of an anhedral design with waverider attribute and blended wing body twin-vertical tail; anaircraft body part of the first-stage aircraft is of a flat design; the back of the aircraft body part is of a smoothed design; and the smoothed part is used for placing the second-stage aircraft; thesecond-stage aircraft adopts an aerodynamic layout with a low aspect ratio sweptback wing, a wing-body combination and a single vertical tail; the aircraft body section of an aircraft body part of the second-stage aircraft is of semicircular and inverted-circular shape; and the belly part of the aircraft body part is a plane and is connected with the smoothed part of the back of the first-stage aircraft. According to the aerodynamic layout of the horizontally taking-off and landing two stage to orbit aircraft, various control functions of the first-stage aircraft and the second-stage aircraftcan be effectively enhanced, carrying requirements of fuel are satisfied, and good thermal protective performance is realized.

Description

technical field [0001] The invention relates to the field of aircraft, in particular to an aerodynamic layout of a two-stage orbiting aircraft that adopts turbine / ram combined power for the first stage and rocket power for the second stage. Background technique [0002] Reuse is an important measure for space-to-earth shuttle vehicles to greatly reduce launch costs, greatly reduce launch cycles, and greatly improve aerospace applications. All space powers have realized that if they want to control the world, they must first control space. Focusing on the demand for fast, reliable and cheap access to space, countries have carried out a series of explorations on the layout of reusable launch vehicles: German scientist Sanger took the lead in proposing the idea of ​​a rocket engine-propelled "Silver Bird" aerospace bomber. Braun and Qian Xuesen proposed the concept of the reusable vehicle RLV. After World War II, the United States proposed a variety of aerospace vehicle concep...
