| 英文摘要: |
| To simulate transient thermal environment during aerocraft reentry, research on the transient heating device under centrifugal and overload condition for some representative samples is conducted. Given quartz lamps are non-durable, fragile and easily broken when used under overload condition, this study proposes structural strengthening, manufacturing techniques improvement and the changing of the clamping method. A transient thermal test using a transient heating device developed by our own group is conducted on a representative sample under overload condition, accomplishing the goal of raising the highest temperature to 600 ℃ and the workload to 80g. The aerocraft’s ground thermal testing under centrifugal condition can be done by this device and test method. |
