摘　　要：研制一套小型热噪声试验装置,开展单一噪声环境、单一热环境、热噪声复合环境施加能力的试验验证,结果表明该装置可实现试验件表面同侧热环境超过600℃、噪声环境超过165 dB的联合施加,可为大型热噪声试验系统研制、热结构设计、试验方案确定等提供技术支撑。One scaled thermal acoustic test apparatus is researched and established. Then, capability verification tests of the single acoustic, the single thermal, and combined thermal and acoustic environments are executed. Results show that the test sample can be applied with 600℃ thermal and 165dB acoustic loads at the same time. It will provide technical supports for the establishment of full scaled apparatus, thermal structure designs and test procedures.
