Problems solved by technology
However, in the field of ramjet engines, ramjet engines at home and abroad are mainly used for one-time bombs. At this stage, there is almost no technology for state monitoring of reusable ramjet engines. The specific theoretical research and methods on the identification criteria are lacking, and the implementation methods have not yet been implemented. Carry out specific application and engineering research, with little method accumulation and no relevant experience and data accumulation

Embodiment Construction
[0018] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0019] The present invention provides a condition monitoring system for a reusable ramjet, such as figure 1 As shown, it includes fault diagnosis standard module, fault state recognition module, controller, fault knowledge base and simulation verification platform.
[0020] The fault diagnosis standard module is used to monitor the functions and characteristics of the ramjet, analyze and establish the discrimination criteria for the technical status of the ramjet. The technical status includes normal status, abnormal status and fault status.
[0021] The fault state identification module is used to compare the collected technical state parameters of the ramjet engine with the judgment criteria to obtain the technical state of the ramjet engine, and use the gas circuit performance monitoring method of the ramjet engine and the life monitoring method of key ...

The invention discloses a state monitoring system for a reusable ramjet. The state monitoring system for the reusable ramjet comprises a fault diagnosis standard module, a fault state recognition module, a controller, a fault knowledge base and a simulation verification platform, and can be applied to power devices of ramjet-level near space aircrafts such as reusable ramjets and turbine ramjet combined engines. With the adoption of the state monitoring system for the reusable ramjet, faults of the reusable ramjet can be found in time, and the availability and maintenance requirements of the ramjet can be determined, so that the safety, reliability and maintainability of the reusable ramjet are greatly improved; and the system is scientific, simple and convenient, intelligence and miniaturization can be achieved, and the informatization and intelligence level of the reusable ramjet is greatly increased.
Description
technical field [0001] The invention relates to the technical field of aerospace reusable ramjet engines, in particular to a state monitoring system of reusable ramjet engines. Background technique [0002] In recent years, the strategic value of near-space and aerospace vehicles has been valued by countries all over the world. Military developed countries such as the United States and Russia have invested a lot of money to actively carry out research on the technology and application of near-space vehicles. my country has also gradually developed aerospace vehicles. research and development. The ramjet has the characteristics of high specific impulse under supersonic flight conditions, and is an ideal power for long-range, high-altitude, high-speed cruising aircraft. With the development of technology and the change of requirements, there are more and more applications for ramjet engines in new types of near-space aircraft and even shuttle vehicles in the aerospace field. ...
