Two-dimensional trajectory correction assembly for aviation guided bomb

Abstract

The invention discloses a two-dimensional trajectory correction assembly for aviation guided bomb. The two-dimensional trajectory correction assembly for aviation guided bomb comprises a GPS receiving device, a missile-borne computer, a steering engine system, a rotating rudder section, a rotating canard rudder piece, a gyroscope, a photoelectric encoder, a lithium battery, an in-situ detection mechanism, a fixed cabin, a motor mounting plate and a mounting plate. The GPS receiving device measures real-time position and speed information of an aerial bomb and sends the real-time position and speed information to the missile-borne computer; the gyroscope and the photoelectric encoder measure the rolling angle of the rotating canard rudder and send the rolling angle to the missile-borne computer; the missile-borne computer obtains a trajectory correction instruction according to the real-time position and speed information of the aerial bomb and sends the trajectory correction instruction to the steering engine system; and the steering engine system adjusts the spatial orientation of the control force and the control moment of the rotating canard rudder according to the trajectory correction instruction to realize trajectory correction. The two-dimensional trajectory correction assembly for aviation guided bomb has the advantages of being simple in structure, low in cost, high in guidance precision and convenient to use and maintain.

Description

technical field [0001] The invention belongs to the field of aviation guided bombs, and in particular relates to a two-dimensional ballistic correction component used for aviation guided bombs, which is installed on the head of the aviation bomb as a guidance control module, and the ordinary aviation bomb is transformed into a satellite guidance mode and relies on aerodynamic force. A low-cost guided bomb that is controlled. Background technique [0002] Two-dimensional trajectory correction technology is an effective way to improve the precision strike capability of conventional uncontrolled ammunition. Two-dimensional ballistic correction bombs usually use the combined technology of inertial navigation and GPS satellite positioning, adopt the aerodynamic layout of canard rudders, and use gliding, extended range, combined guidance and flight control technologies to achieve low-cost and precise strikes of ammunition. Due to the limitation of key technologies such as miniatu...
