Abstract

The invention relates to a demand and calculation model association verification method and system, a storage medium and equipment, and aims to solve the technical problems of large workload, error proneness and untimely updating caused by data non-intercommunication between a demand model and various calculation models in a scheme design process of a current liquid rocket engine system. The method comprises the following steps: 1, constructing a demand model and a plurality of calculation models; 2, establishing association between the demand model and the calculation model; 3, updating design parameters of the demand model to the calculation model; 4, solving the calculation model; 5, comparing the calculation result of the calculation model with the performance parameters of the demand model, and if the requirement is met, ending; and if the requirements are not met, adjusting the calculation model or the demand model, and returning to the step 3 until the requirements are met. The system comprises a demand model module, a calculation model module, a variable association module, a parameter reference module and a demand verification module.

Description

technical field [0001] The invention relates to a design method of a liquid rocket engine system, in particular to a method, system, storage medium and equipment for verifying the correlation between requirements and calculation models of a liquid rocket engine system. Background technique [0002] The design of the liquid rocket engine system is a multi-task and multi-model process. Different tasks correspond to different models, which mainly include demand models and various calculation models. There is a data correlation between the models, such as the propellant type, specific impulse, mixing ratio, engine thrust, total system weight, system reliability and other parameters in the demand model will be used in subsequent calculation models. At present, there is no relationship between the demand model and various design calculation models, the data is not interoperable, and the various models are separated from each other. When one of the parameters is modified, it is ne...
