A parallel test simulator has been used to accumulate over 1000 start-stop cycles to demonstrate the life of the bearing and coating. Based on this successful testing, it is expected that the goal of developing oil-free turbochargers and small turbojet engines that operate at high speeds with ...
Initial aero/mechanical tests of the Multi-Mission Aircraft Propulsion Simulator were conducted in the AEDC R2C4 Test Cell of the engine test facility. A t... BR Delaney,H West 被引量: 2发表: 1973年 PERFORMANCE ANALYSIS AND IMPROVEMENT OF THE LUBRICATION SYSTEM OF THE TURBOFAN AERO-ENGINE ...
Detailed engine integration studies, bearing component rig testing and hot engine simulator tests were completed prior to the successful engine test. The rig and simulator tests verified high temperature capabilities of the bearing and its surface coating, the bearing journal design, bearing dynamic ...
Two candidate solid lubricants, molybdenum disulfide and cesium oxythiotungstate, and two bearing greases were evaluated using a bearing and rotor dynamics simulator rig. The rotor shaft with integral bearing inner raceways and the outer races were machined from the PSO-H1 blanks by a vendor. ...
