Method for rapidly determining overall parameters of boosting gliding missile

Abstract

The invention provides a method for quickly determining overall parameters of a boosting gliding missile, which comprises the following steps: inputting a missile target range, and dividing a trajectory into a boosting section, an adjusting section, a gliding section and a terminal guidance section; calculating the range of each section according to the position and speed requirements of the trajectory shift point; accumulating the firing ranges of the boosting section, the adjusting section and the gliding section to obtain a total firing range, comparing the total firing range with a targetfiring range, and iteratively solving to enable the total firing range to meet the target firing range requirement so as to determine a target trajectory; obtaining a trajectory parameter estimation value according to the target trajectory; obtaining a shutdown point structure ratio and a missile quality requirement according to the target trajectory, and obtaining a quality parameter estimation value; and obtaining a power parameter estimation value according to the quality parameter estimation value. According to the method for rapidly determining the overall parameters of the boosting gliding missile, subsection trajectory calculation, reasonable assumption and application of an empirical formula are adopted, and the calculation speed and efficiency can be greatly improved on the premise that certain solving precision is guaranteed.

technical field [0001] The invention relates to the field of aircraft technology, in particular to a method for quickly determining the overall parameters of a boost-glide missile. Background technique [0002] The boost gliding missile uses a booster to push the missile to a certain height and a certain speed to separate the gliding body. The gliding body effectively uses the aerodynamic lift to perform long-distance maneuvering gliding flight in the atmosphere. It has a long range, high precision, and flexible maneuverability.

[0003] The design of the overall parameters of the missile is the basis of the missile design, and the rapid acquisition of the overall parameters in the scheme demonstration stage will help to improve the overall design efficiency and shorten the design cycle. The current overall parameter design methods are mostly aimed at ballistic missiles. Since ballistic missiles h...

AI Technical Summary

Problems solved by technology

The ballistic apex of the boost-glide missile is mostly within 60km, and the range coverage mainly depends on the ability of the gliding body to use aerodynamic force in the atmosphere for maneuvering gliding flight. If it is not established, the ballistic solution method based on the assumption of vacuum flight cannot be applied; on the other hand, the ballistic characteristics of boost gliding missiles are quite different from those of ballistic missiles. Three-stage ballistic solution, the introduction of large system errors, low reliability of calculation results, unable to meet the requirements of solution accuracy
