Abstract
Description
Technical Field
[0001] This invention belongs to the field of material performance testing technology, specifically relating to a wide-temperature-range multi-carrier erosion and burn-off joint assessment and testing device suitable for aero-engine power components. Background Technology
[0002] As the most important power source, the impact of aero engines on aircraft performance is self-evident, and their development level reflects a country's industrial strength. Their internal power components often face high-temperature combustion gases and complex heterogeneous coupling effects, leading to various forms of damage. Therefore, variable acceleration testing platforms simulating service conditions have emerged. Damage test results under high and low temperature multi-carrier conditions can effectively verify reliability and stability under actual operating conditions, and have practical significance in the field of damage mechanism research.
[0003] Currently, a series of testing platforms have been established for high-temperature testing of engine components, mainly divided into two categories: multi-level variable screening and fitting measurement devices and global jet wind tunnel acceleration testing platforms. Conventional multi-level variable screening and fitting measurement devices often only consider narrow-range high temperatures and the effects of typical three-phase carriers. The small controlled temperature range means that the testing scope is significantly limited. The assignment of values for typical carriers means that the construction of subsequent experimental models deviates from real conditions. At the same time, there are few reports on high-temperature condensed particle erosion conditions based on combustion products. Global jet wind tunnel acceleration testing platforms have high experimental costs and cannot be used as routine experimental models. Therefore, it is urgent to build a comprehensive damage testing and evaluation system to comprehensively test engine components based on the characteristics of a wide temperature range and multiple carriers. Summary of the Invention
[0004] The purpose of this invention is to simulate the low-temperature, high-temperature, and ultra-high-temperature operating conditions faced by aero-engine power components during service. It employs methods of global heating and localized directional burn-off, while also considering the harsh operating conditions of high-temperature, high-speed, multi-carrier components such as sand, volcanic ash, and other erosive carriers during flight. In particular, it considers the high-temperature condensed particles generated by the components themselves during operation. The invention performs graded damage testing on aero-engine power components (intake fan, compressor blades, turbine blades, combustion chamber wall, and exhaust nozzle), thereby providing a wide-temperature-range multi-carrier erosion burn-off joint testing system suitable for aero-engine power components that combines accuracy and efficiency.

[0010] This invention studies the separation of variables under actual working conditions and performs nonlinear fitting, comprehensively considers the influence weight of each damage factor on service life, and completes precise adjustment by controlling the hierarchical transformation of multivariate parameters and coordinating with the robotic arm at the testing end, so that the damage test results can fully match the working conditions of engine components.

[0022] This implementation method, based on erosion damage testing under normal temperature conditions, sets up a wide-temperature-range variable-temperature environment. The high-temperature heating chamber door allows for sample clamping and adjustment of the testing device's degrees of freedom.

Ceramic protective materials protect the heating coils from damage during multi-carrier erosion. An internal temperature sensor allows for accurate setting of the experimental temperature on the control panel. In ultra-high temperature testing environments above 800°C, to prevent high-temperature oxidation failure of the clamping system, a localized burn-off device is used for ultra-high temperature directional testing. Simultaneously, the high-temperature heating chamber maintains a certain level of ambient temperature.
[0023] This implementation method can meet the damage analysis requirements of erosion and burn-off of aero-engine power components in high-temperature, high-speed, and high-pressure multi-carrier operating environments. It constructs high-temperature condensed-phase particle conditions by selecting and adding combustion product solid carriers and silicate droplets. A six-axis robotic arm and sample embedded fixture can be designed to determine the erosion-burn-off angle of the sample.

In addition, the real-time monitoring camera 26 is used to monitor the location of erosion and burning.
[0040] In this embodiment, the multi-carrier erosion and burn-off coupling test system draws in air from the air compressor 6, which is connected to the gas storage device 8 via the atmosphere buffer device 7. During the experiment, the connecting pipeline valve is opened, and the gas flow rate is adjusted by the gas turbine flow meter 9 on the pipeline. Multi-component solid carriers are added through the feeding port 10-1. Based on the analysis of actual working conditions, they are added as needed to the large particle size solid phase reaction device 10, the simulated secondary erosion debris solid phase reaction device 11, and the simulated combustion product solid phase reaction device 12. The solid carriers can be preheated by the induction heating device 13 and then fed into the solid carrier nozzle 29.

[0042] Gasoline or kerosene is added to the burn-off material supply system 20. The high-pressure environment created by the protective gas inside the device 19, propelled by airflow, is used to control the ablation conditions via the burn-off material flow meter 21, constructing a localized, directional, ultra-high temperature heating environment. The heating temperature range of the heating element 2 is controlled via the temperature control panel 4, creating a wide temperature range test range in the high-temperature heating chamber 1. Combined with the temperature sensor 5 inside the chamber, the actual temperature range can be displayed.

After the experiment, dust is collected by the dust removal device 24 and enters the recovery system. The system's negative pressure device 24-1 creates a negative pressure atmosphere, causing the solid-phase carrier to move towards the solid-phase separation filter element 24-2. Finally, the solid-phase carrier is graded and recovered through filter elements of different pore sizes.
[0043] The particles added to the solid phase carrier module in this embodiment are mainly: solid hard particles (Al2O3 or SiO2), erosion debris simulating the front-end components, micro carbides generated in the combustion chamber simulating combustion, abnormal solid particles generated by rich oil combustion, small-diameter soot particles and other combustion product particles. Each solid phase reaction vessel is controlled by a separate valve to prevent contamination. The salts added to the liquid phase mixing module are mainly divided into two categories: silicates and phosphates. Silicates and phosphates simulate the CMAS erosion failure conditions faced by aero engines and the service environment of carrier-based aircraft. They can be converted from high-pressure atmosphere into small droplets and injected from the liquid phase carrier nozzle 30.
[0044] The induction heating device designed for the solid support module is used for preheating the solid support before the experiment, and its heating range is from room temperature to 200℃. The solid support nozzle 28 and the liquid support nozzle 29 together constitute a multi-support test generator, and its nozzle can rotate 180° to meet the requirements of different erosion angles of the sample.
[0045] The high-temperature heating chamber 1 is operated via the temperature control panel 4. The heating element 2 has a heating temperature range of 0-900℃. Due to the presence of the ceramic protective material 3, the actual heating temperature is below 900℃. The actual temperature range can be displayed by the temperature sensor 5 inside the chamber, and the actual temperature should be above 800℃. The ultra-high temperature environment provided by the localized burn-off device is controlled by the combustion carrier within the ultra-high temperature range.
[0046] Under the harsh operating conditions of high temperature, high speed, and high pressure, the high-temperature heating chamber 1 of this invention serves as an experimental platform and a comprehensive high-temperature heating environment. The heating temperature range of the heating wires 2 is controlled via the temperature control panel 4, creating a wide temperature range for testing. In ultra-high temperature testing environments, based on the comprehensive insulation conditions provided by the high-temperature heating chamber 1, ultra-high temperature directional testing is completed using a localized heating device through a burn-out nozzle 31.
[0047] This invention constructs an adjustable test range through a global heating device and simulates the damage environment of ultra-high temperature components through a localized burn-out device, ultimately achieving the construction of wide-temperature-range damage conditions.
