An Aerodynamic Layout of a Transatmospheric Reusable Vehicle

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...
