Problems solved by technology

[0004] Theoretical studies have shown that when an axisymmetric aircraft adopts conventional symmetrically distributed flap rudders, since the normal force of the flap rudder surfaces passes through the aircraft axis, there are defects in the flight control of the roll channel, and the conventional symmetrically distributed flap rudder surfaces cannot achieve alignment. aircraft roll control

specific Embodiment approach

[0020] For the axisymmetric hypersonic vehicle with ball-cone-column configuration, a new flap-controlled rudder surface layout shape is invented. This layout not only has the characteristics of small aerodynamic interference, low thermal protection pressure, and high space utilization, but also can realize effective control of the three channels, especially the rolling channel. The features of the aircraft include: a spherical-cone-cylindrical axisymmetric fuselage; a flat flap rudder at the bottom of the fuselage; the flap rudder is connected to the bottom of the fuselage through the rudder shaft, There are different distances and installation angles. Outline diagram such as figure 1 shown. The specific implementation is as follows:

[0021] Firstly, the shape of spherical-cone-cylindrical axisymmetric fuselage is designed. By adjusting the length and angle of the cone section and the length of the column section, the stability and maneuverability of the axisymmetric air...

Abstract

The flap rudder layout for enhancing the rolling-control capability of a hypersonic aircraft is a layout form applied to a spherical-conical-cylindrical axisymmetric hypersonic aircraft, and the aircraft obtains a control moment through flap rudder deflection so as to control the flight attitude. The flap rudder is designed into a flat plate structure and is mounted at the bottom of the aircraft through a rudder shaft. The designed installation angle of the flap type rudder remarkably improves the rolling-control capacity of the aircraft, and effective distribution of pitching, yawing and rolling control efficiency of the aircraft is achieved.

Description

technical field [0001] The invention is applied to the aerodynamic shape design of hypersonic aircraft, and belongs to the field of aerodynamic layout design of hypersonic aircraft. Background technique [0002] Hypersonic aircraft has the characteristics of fast speed, strong defense penetration capability, and strong strike timeliness, and has become the focus of the development of major military powers in the world. In recent years, with the increasing maturity of missile defense technology, new requirements have been put forward for the maneuverability and rapid risk avoidance capabilities of high-speed sonic aircraft. Countries are actively developing new types of high-speed maneuverable hypersonic aircraft. [0003] For ball-cone-cylindrical hypersonic reentry vehicles, maneuvering flight is generally achieved by installing air rudders. The air rudder mostly adopts the empennage rudder or flap rudder scheme. Flap rudder has the advantages of small aerodynamic interfe...
