A LCF(Low Cycle Fatigue)test of a single rotor disk of a compressor is *** experimental results show that the location and the growth orientation of LCF crack in 9th single rotor disk reproduce those in the global compressor *** addition,the LCF tests of the smooth round bar specimens are accompanied with the LCF tests of a single rotor disk,so as to estimate of the strain history of the eccentric holes in the *** statistical data of smooth round bar specimens tested to failure enables to estimate the LCF life to crack initiation for the eccentric holes in the disk of the global compressor rotor.

A microcomputer controlled high speed high temperature rotating tester with variable amplitude cycle has been constructed and oprerated to estimate the LCF life of gas turbine *** far the tester has worked about 2500 hours(total cycle index is about 50000),without essential *** data of the variable amplitude LCF life for seversl disks have been *** data are of high *** is testified that the test equipment is sufficient for preformance research of rotating disks with diameter up to 1m and weiget up to *** disk is mounted vertically on flexible shaft;an ***(125kw)drives the disk up to *** heater can raise the temperature of the disk up to 800±5℃.The average speed error for a run is less than 0 1%;the maximum instantaneous error is about 0 5%.A vacuum pump is used to sustain about 400 to 667Pa in the chamber of the tester.

A way to construct a clean combustor with high performance and low contamination is proposed by means of installation with beforehand mixing and *** measurement or accurate calculation of the evaporation rate in the evaporation installation is very difficult. According to energy relation,calculation is made based on the quasi steady state evaporation model at the angle of engineering *** concept of greatest evaporation rate of fuel in the evaporating installation is presented,and the effect of some primary factors is *** calculated results are compared with test data.
