Abstract

The invention belongs to the aerial projection technology of an aircraft, and relates to a blind projection method of an airborne gliding bomb. The steps of the blind drop are as follows: mount the bomb; pre-store the flight parameters of the carrier aircraft that need to be transmitted; adjust the flight status of the carrier aircraft; release. The invention reduces the requirement of the gliding bomb on the carrier aircraft, and improves the adaptability of the gliding bomb. Increased the combat capabilities of backward aircraft that do not have the ability to transmit information.

Description

technical field [0001] The invention belongs to the aerial projection technology of an aircraft, and relates to a blind projection method of an airborne gliding bomb. Background technique [0002] Representative products of precision-guided bombs at home and abroad using INS+GPS guidance include JDAM, JSOW, and dispensers. Such bombs generally use the inertial system as the main navigation sensor. The initial alignment time and accuracy of the sub-inertial system before the bomb is launched will directly affect the bomb’s navigation and guidance accuracy and attack performance after launch. In order to eliminate the influence of various factors and establish an accurate inertial reference datum on the bomb, it is required that the sub-inertial navigation system must be initially aligned on the flying carrier aircraft through the information transfer between the main and sub-inertial navigation systems before the bomb is dropped. That is to complete the alignment of the air ...
