| Abstract: | The material selections and thermal-structural designs for the typical passive thermal protection components,such as the cowl leading edges and fuel injection struts,were investigated by the tests on the electric arc heater instrument.The method of thermal-structural analysis for the actively cooled combustor was developed,and the thermal evaluation code validated by the experiments was applied to the combustor material coupon.The cowl leading edges made of materials C1 and C2 were in good condition after 60s test.The fuel injection struts made of material Z1 were in good condition after 50s test.The actively cooled combustor thermal analysis and calculation procedures were applied to the cooling panel tests.The maximum temperature difference between the measurement value and the calculated value was 55K,showing good agreement of the calculation and experiment.So,the calculation program can provide credible reference data for the material configuration design of the actively cooled combustor.The experience and technology learned from the approach will be incorporated into the design and demonstration of complete free jet engine. |
