| Abstract: |
| The work aims to develop a heat test apparatus to evaluate the environmental adaptability of the aircraft products under the thermal-centrifugal compound environment. In this work, the functions and index of the apparatus were formulated from the needs of the test, especially the way to heat under heat transmission form and the optimal design of hardware layout under the high g-value (centrifugal acceleration value, ≥90 g) centrifugal environment. The simulation and implementation method of the response temperature gradient distribution based on segmented envelope thoughts was proposed to reduce excessive test. A thermal-centrifugal compound environment functional verification test for the thermal control device was carried out with the maximum acceleration of 92 g, a load keeping period of 3 min, the maximum heating temperature of 150 ℃, and the maximum temperature rising rate of 3 ℃/min. In 3-temperature zone control, the deviation of the temperature during temperature rise was superior to ±1.5 ℃. The thermal control device for the thermal-centrifugal compound environment test can be used for examination of aircraft products in thermal-centrifugal compound environment tests. |
