Problems solved by technology

The size of the deviation will directly affect the rocket design. If the deviation is too large, the rocket design will be too conservative and increase the design difficulty; if the deviation is too small, it will not be able to cover all the deviations, which will bring risks to the design.

Embodiment Construction

[0026] In order to make the technical solutions and advantages of the embodiments of the present application more clear, the exemplary embodiments of the present application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, and Not all embodiments are exhaustive. It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict.

[0027] In the related art, the determination of the total deviation of the rocket should be obtained according to theoretical analysis and statistical analysis of various actual data. In the early stage of development, due to the lack of actual data, theoretical analysis or borrowing data from previous models is generally emphasized; with the progress of engineering development, data is continuously accumulated, and devia...

Abstract

The embodiments of the present application provide a method, system, terminal and medium for determining the overall deviation of a launch vehicle, and relate to the overall design technology of a launch vehicle. The method for determining the overall deviation of a launch vehicle includes: obtaining a probability distribution model of the overall deviation pre-established according to at least one of deviation source information and interference information; obtaining a pre-established overall parameter model; according to obeying the probability distribution The random numbers of the model and the overall parameter model determine the overall deviation of the target launch vehicle.

Description

technical field [0001] The present application relates to the overall design technology of launch vehicles, in particular to a method, system, terminal and medium for determining the overall deviation of a launch vehicle. Background technique [0002] The overall deviation refers to the maximum possible deviation between the data given in the initial data design of the launch vehicle and the actual value of the product, and is an important content of the initial data. The overall deviation of the rocket mainly includes the deviation of the size of the rocket structure, the deviation of the mass characteristics, the deviation of the engine performance and the deviation of the overall parameters. The size of the deviation will directly affect the rocket design. If the deviation is too large, the rocket design will be too conservative and the design difficulty will be increased; if the deviation is too small, it will not cover all the deviations, which will bring risks to the d...
