Abstract

The invention provides a ballistic trajectory calculation method of an umbrella bullet system. Data needing to be input are analyzed and collected, wherein the data comprise umbrella quality characteristic parameters, geometric structure parameters and resistance characteristic parameters, bullet quality characteristic parameters, geometric structure parameters and resistance characteristic parameters, initial movement speed, posture, height and the like of the umbrella bullet system; nine-degree-of-freedom dynamic modeling is carried out on the umbrella bullet system, and ballistic calculation is carried out. According to the ballistic trajectory calculation method of the parachute bomb system, the precision is high, the speed is high, the requirements for the calculation speed and precision in engineering can be met, and the technical problem that in the prior art, the precision and the calculation speed of a parachute bomb system modeling method cannot be achieved at the same time is solved.

Description

technical field [0001] The invention relates to the technical field of missile flight dynamics, in particular to a ballistic calculation method. Background technique [0002] In modern warfare, the attack on surface targets such as airport runways and technical weapon positions is mainly achieved by distributing sub-munition groups with drogue parachute from the air through a dispensing device platform with / without power. The sub-munitions with drogue parachute are A more typical umbrella bomb system. With the help of the deceleration parachute, the parachute system can have good aerodynamic characteristics and stable deceleration ability, prevent the ammunition from tumbling in the air, make the whole trajectory stable, ensure the accuracy of the ammunition’s landing point and the required landing attitude and speed, and ensure the effectiveness of the ammunition on the target. Damage creates conditions. [0003] In order to ensure the stability of the trajectory, higher ...
