Fire work throwing type anti-stabilizing wing

Abstract

The invention provides a fire work throwing type anti-stabilizing wing which is installed at the head of an aircraft, can reduce the influence of environmental wind on the initial stage of the aircraft, and achieves the precise control of the trajectory of an uncontrolled aircraft. The fire work throwing type anti-stabilizing wing comprises an airfoil component and a fire work actuator, wherein the airfoil component comprises an airfoil and a mounting seat; the fire work actuator is installed on the inner wall of a cabin of the aircraft, an actuating shaft of the fire work actuator extends out of the cabin and then is connected to the mounting seat, the mounting seat is provided with two airfoil mounting seat grooves, and the two airfoils are respectively fixed in the two airfoil mounting seat grooves; the airfoil is an anti-stabilizer; and the fire work actuator works under the control of a preset ignition time sequence, and when the aircraft flies to a preset moment, the fire work actuator works, so that the airfoil component is separated from the cabin.

Description

technical field [0001] The invention relates to an anti-stabilizer, in particular to a pyrotechnic throw-off anti-stabilizer of an aircraft, and belongs to the technical field of aircraft design. Background technique [0002] The trajectory of the uncontrolled aircraft (especially the trajectory of the active segment) is greatly affected by the ambient wind. In the case of wind, the position vector and velocity vector of the end point of the active segment of the aircraft will deviate from the nominal value. [0003] In order to reduce the impact of ambient wind on the trajectory, the most common method for uncontrolled aircraft is to use the wind repair method to correct the launch angle and azimuth angle of the aircraft according to the measured wind field meteorological parameters. "Research on Wind Repair Calculation of Rocket Launch Table" (Journal of Missiles and Guidance, Vol. 21, No. 3, 2001) introduced the wind repair principle of uncontrolled rockets, and introduce...

Problems solved by technology

[0006] 1. Real-time difference

[0007] There is always a time difference between wind field measurement, wind repair calculation, and launch aiming track to complete ignition and launch. However, the environmental wind field at the launch site is dynamically changing, especially when the wind speed is high, resulting in greatly reduced wind repair effects, or even unsatisfactory flight requirements

[0008] 2. The consistency of wind field data varies greatly

[0009] First of all, the current emission environment wind field data obtained by measuring equipment such as sounding balls and wind radars are above a certain height and the average results within a certain period of time cannot effectively reflect the transient changes of the wind field, especially the ground wind field is affected by the emission. The change of surface conditions is more complicated, and the main influence area of ​​wind on the flight deviation of uncontrolled rockets is mainly in the initial stage of rocket take-off; influences
