Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings.

[0029] Such as figure 1 and figure 2 As shown, the layout of the transatmospheric reusable aircraft provided by the present invention includes a head 1, a fuselage 2, a horizontal wing 3, a vertical empennage 8, body flaps 5 and a liquid hydrogen / liquid oxygen linear plug nozzle rocket motor 6 . Two inclined horizontal wings 3 are arranged on both sides of the tail of the fuselage 2, two vertical empennages 8 are arranged on the back of the fuselage 2, and two body flaps 5 are also arranged on the lower surface of the fuselage 2 bottom. The liquid hydrogen / liquid oxygen linear plug nozzle rocket engine 6 is arranged at the tail position of the fuselage 2 . This layout has no booster, and a single stage can be launched from the ground into orbit, and can return to glide to land and be reused.

[0030] The rear edge of the horizontal wing 3 is provided with a roll a...

Abstract

The invention discloses an aerodynamic layout of a transatmospheric reusable aircraft, which comprises a head, a fuselage, a horizontal wing, a vertical tail, a body flap and a liquid hydrogen/liquid oxygen linear plug-type nozzle rocket engine. The invention has no booster, and adopts a single stage to vertically launch into orbit from the ground; after completing the mission, it can return to the atmosphere and glide horizontally to land, and can be completely reused after recovery. Through reasonable aerodynamic configuration and optimized design, the aircraft has a high lift-to-drag ratio and good stability and maneuverability in a wide range of altitudes and speeds. At the same time, the fuselage has a large effective volume and needs to carry propulsion Dose less. The invention has low launching cost, short launching preparation period and high reliability. It can overcome the shortcomings of current space vehicles that cannot be completely reused, expensive to launch, and cumbersome to use and maintain. It can be used not only for military space missions, but also for commercial and civil space services.

Description

technical field [0001] The invention relates to an aircraft, in particular to an aerodynamic layout of a reusable aircraft across the atmosphere. Background technique [0002] Space delivery systems currently in use, with the exception of space shuttles (which are partially reusable), are all disposable. Product manufacturing costs for single-use vehicles represent a significant percentage of the total cost of a launch. For example, for the Ariane rocket in France, the product manufacturing cost accounts for 81.4% of the total cost of each launch, while the launch operation cost only accounts for 15%, and other costs account for 3.6%. Therefore, one of the most effective ways to reduce the launch cost is to reduce the hardware cost of the launch vehicle. However, at the current level of technology, it is impossible to significantly reduce the hardware cost of single-use vehicles (ELVs). Even the development of an Enhanced Single-Use Vehicle (EELV) is unlikely to significa...
