In view of the problems of oil pollution and low reliability existing in the oillubricated ball bearing of a certain inland airborne pod ECS turbine,airborne aerodynamic foil bearings(AFB) was developed based on pod turbine actual using conditions,and the verification experiments on performance,function vibration,storingstarting storing and starting tests in low and high temperature were conducted.The results show that the cooling capability,rotor floating pressure and speed of turbine with AFB satisfy the operation requirements.The results of function vibration tests,storing and starting tests at -55 ℃ and 70 ℃ are better than performance requirements.The plate foil coatings are in good integrity after overspeed test and over a hundred times start-stop tests,and the startstop times will be more than 10 000
