Material ignition point test assessment device and assessment method

Abstract

The invention provides a material ignition point test assessment device and assessment method, and solves the problems that the existing material temperature performance data is limited, and the material ignition point is difficult to verify due to the fact that the existing metal ignition test cannot provide high-temperature and high-pressure oxygen enrichment conditions. The material ignition point test assessment device comprises a fuel gas generator, a water cooling section, a test piece clamping section, a monitoring section and a process spray pipe which are sequentially communicated, wherein the fuel gas generator is used for providing high-temperature and high-pressure oxygen-enriched fuel gas for the test piece to be assessed; the water cooling section is greater than or equal to600 mm and used for improving the uniformity of the fuel gas; temperature sensors and pressure sensors are arranged on the water cooling section and the monitoring section and are used for monitoringthe temperature, pressure and pressure fluctuation conditions of the front and rear parts of the to-be-assessed test piece; the process spray pipe is used for controlling the incoming flow pressure ofthe oxygen-enriched fuel gas; and the water cooling section, the test piece clamping section, the monitoring section and the process spray pipe are all made of a high-temperature alloy material.

Description

Technical field [0001] The present invention is in material properties evaluation test apparatus, particularly relates to an ignition point of a material testing apparatus and assessment evaluation method. Background technique [0002] Liquid propellant rocket engine, certain components (e.g., individual components of a gas path structure: gas pipe, a turbine stator and a rotor, etc.) in a high temperature working environment, with the increase (e.g., engine performance requirements: high performance liquid oxygen kerosene afterburner cycle engine), the working environment of the engine parts are becoming more stringent, the operating temperature is also facing new challenges. [0003] To accommodate more demanding work environment, improve engine performance should be established to acquire all components in a high temperature environment Researchers used on the basis of material properties, but temperature performance data material has been unable to provide powerful data for t...
