Description

Technical Field

[0001] The invention relates to the technical field of high temperature testing, in particular to a quartz lamp radiation heater. Background Art

[0002] Aircraft have aerodynamic heating problems during high-speed flight, and it is necessary to conduct simulated heating tests on the ground to evaluate the thermal insulation, heat resistance, thermal matching and other properties of its structure. In recent years, the demand for aircraft structural thermal tests in low-pressure environments has become increasingly prominent. The test object and heating equipment are placed in a closed, low-pressure space for testing to simulate the low-pressure or vacuum thermal environment after the aircraft flies out of the atmosphere. The quartz lamp radiation heater is used to simulate the heat generated by the friction between the aircraft and the air, thereby determining whether the strength of the fuselage material can withstand the thermal stress generated by aerodynamic heating. In order to ensure the reliable operation of the quartz lamp heater, this paper uses numerical simulation methods to analyze its thermal performance and structural stress. Quartz lamp radiation heating is a heating method on the ground to simulate the thermal load applied to the aircraft surface during flight. Due to the different distribution of quartz lamp heating elements, the heat flux density obtained in different areas of the test piece surface is different from the required heat load, which may lead to "over-test" or "under-test" phenomena, thereby reducing the availability of test data and increasing the risk of structural design. Based on the Monte Carlo method, this paper numerically simulates the internal heat flux distribution of a single quartz lamp heater, providing a theoretical reference for more reasonable optimization of the internal thermal field distribution of the heater and improving the quality of thermal tests.
