Virtual testing platform of liquid rock engine and testing method thereof

Abstract

The invention discloses a virtual testing platform of a liquid rock engine and a testing method thereof, comprising a test manager module, a test object simulating module, an operation control module, a virtual environment module, a verification evaluating module and a database managing system. By determining a test object and a test proposal, the operation control module controls the simulation process of the test object simulating module, the virtual environment module performs three-dimensional display and entity mapping, the verification evaluating module evaluates a virtual test result, and the database managing system stores and manages data information, thus realizing the combination of the engine testing technology and the computer method, achieving the effect that the virtual testing platform serves as a seamless integrated system of a project, being led to be similar to true test operating practice, and being capable of having functions and performances similar to a true engine igniting test to a certain extent.

Description

technical field [0001] The invention relates to a liquid rocket engine virtual test platform and a test method thereof, belonging to the technical field of engine virtual test. Background technique [0002] At present, in the development and development of many systems in my country's aerospace and military fields, the development of the power system is mainly completed by ground tests. engine performance etc. However, the ground test system has poor versatility, accumulated errors, and the development process is long and expensive. Therefore, it is of great significance to carry out new forms of experimental research to shorten the development cycle of new types of engines and reduce the cost of development and testing. [0003] With the development of aerospace technology, the cognitive requirements for the complex performance characteristics of the engine are getting higher and higher, and the corresponding requirements for its test technology are becoming more and more ...

AI Technical Summary

Problems solved by technology

[0004] However, when using simulation equipment to simulate the test process, the simulator needs to manage the numerical values ​​of the hot test plan, test process and test results, or operate and manage multiple commercial software, which is poor in compatibility, inconvenient, and not intuitive, so , there is an urgent need for a comprehensive management platform to realize the integration of a large amount of data and software, which can realize the intuitive expression and interactive hot test process of the engine system
