Based on a series of signal process and noise source identification techniques, especially the major noise source identification methods, such as expurgation method, sound intensity analysis, spectrum analysis vibro-acoustic correlation analysis and so on, the pass-by noise control of SC7080A and SC6360B are studied in detail. By the roadway and dais experiments, the major noise and radiating parts are identified and some economical controlling methods are made. For the SC7080A, to control the emissing noise from the intake and shell vibration of air cleaner, a intake muffler is installed between the air cleaner and intake valve. Based on the theory of Helmholtz resonator, One three-parallel-connected resonant silencer is designed and trial-manufactured. For the SC6360B, the attenuation performance of exhaust muffler in high frequency region is improved. To reduce the vibration noise of shell part, the structure of oil sump tank, exhaust manifold shield and exhaust manifold shield are analyzed and improved. At the same time, some measures, such as sound absorption, sound insulation, are taken to reduce the noise of engine surface emissivity and a sound shield is designed.

A test model of four co-rotating disks was developed as the simplified version of a typical internal cooling system of a gas turbine compressor. The investigation was on the distribution of local heat transfer coefficient and the averaged nusselt number of the downstream main disk. Experimental analysis may lead to following conclusions: the distribution is not of monotony and multi-peaks were found along the disk surface,Nu increases with the decrease of the rotational reynold number Re(subscript w,Nu increases with the axial reynold number and the grasholf number.

针对航空发动机多级压气机盘腔的冷却问题，对具有轴向通流的三腔模型进行了系统的研究，通过对局部换热特性与平均换热特性的分析，可以表征旋转盘的热应力水平和相对冷却效果，结果表明表征旋转盘热应力水平的局部换热特性在旋转盘的半径上呈多峰分布，表征相对冷却效果的平均换热特性与旋转雷诺数Re、进气雷诺数Re以及格拉晓夫数Gr有关，当Re及Gr增加时，平均努塞尔数Nu随之增加，而Re的增加使之减小。
