以汽油为燃料、空气为氧化剂，研究了两相脉冲爆震燃烧室和脉冲爆震涡轮发动机在不同工作频率下的噪声辐射特性。给出了单脉冲爆震燃烧室管和脉冲爆震涡轮发动机的噪声辐射声压数据。实验结果表明，工作频率为5Hz～25Hz时，内径为60mm的PDTE出口的峰值声压级约为157dB，而相同条件下单脉冲爆震燃烧室出口的峰值声压级约为170dB。脉冲爆震涡轮发动机的远场射流噪声测量表明，径流式涡轮与脉冲爆震燃烧室的相互作用可以降低脉冲爆震燃烧室的峰值声压级，在当前测试条件下最大声衰减约为14.2dB，这可能有助于径流式涡轮从脉冲爆震燃烧室排气流中提取能量。脉冲爆震燃烧室和脉冲爆震涡轮发动机出口的声压级是距排气中心线的方向角的函数。在所有实验中，汽油/空气混合物的当量比和填充分数分别为1.2和1.0。
The noise radiation characteristics of two-phase pulse detonation combustor and pulse detonation turbine engine were investigated under different operating frequencies utilizing gasoline as fuel and air as oxidizer. The sound pressure data of noise radiation were presented for both single-pulse detonation combustor tube and pulse detonation turbine engine. The experimental results implied that the peak sound pressure level of PDTE exit with inner diameter being 60 mm was about 157 dB under the operating frequencies which varied from 5 Hz to 25 Hz, while the peak sound pressure level of single-pulse detonation combustor tube exit was about 170 dB under the same condition. The far-field jet-noise measurements of the pulse detonation turbine engine showed that radial turbine interacting with the pulse detonation combustor could decrease the peak sound pressure level of pulse detonation combustor with the maximum acoustic attenuation being approximately 14.2 dB for the current test conditions, which could be contributed to the energy extraction by the radial turbine from the pulse detonation combustor exhaust flow. The sound pressure level of both pulse detonation combustor and pulse detonation turbine engine exit was function of directivity angle from the exhaust centerline. In all the experiments, the equivalence ratio of gasoline/air mixture and the fill fraction were 1.2 and 1.0, respectively.
