Study of Micro-High Speed Bearings and
Micromachine gas turbines require extremely high rotor speed to realize the same impeller tip speed to the large gas turbines, by very small diameter of the impellers. Hence, the rotordynamics is one of the critical issues. Especially, the bearing speed will exceed the range of experience in any existing turbomachines, and hence the method to achieve the stable operation at the required design ...
متن کاملDynamic Response of Self-Acting Foil Bearings
A new approach to the analysis of wide foil bearings is investigated. The equation of motion for a finite length of tape is coupled to the transient lubrication equation for the air film between the tape and the recording head. Compressibility and slip flow are retained in the fluid mechanics equation; flexural rigidity and high-speed dynamic effects are retained in the tape equation. The stead...
متن کاملTechnical Development Path for Foil Gas Bearings
Foil gas bearings are in widespread commercial use in air cycle machines, turbocompressors and microturbine generators and are emerging in more challenging applications such as turbochargers, auxiliary power units and propulsion gas turbines. Though not well known, foil bearing technology is well over fifty years old. Recent technological developments indicate that their full potential has yet ...
متن کاملTurbo Machinery Failure Prognostics
The turbomachinery systems on oil platforms are extremely sensitive, as their failure can cause total shutdown of the platform's production activity. Scheduled stoppages for preventive maintenance are effective, since qualified personnel and replacement parts are available and ready. On the other hand, shutting down a turbo machine ceases petroleum production. Not rarely, maintenance people con...
متن کاملA High-Speed Analog Turbo Decoder
A new type of iterative decoders based on analog computing networks, which are used to decode powerful error-correcting schemes, such as Turbo and Low-density parity-check (LDPC) codes, outperform their digital counterparts in terms of power consumption and speed. Only few analog Turbo decoders, all of them based on CMOS subthreshold technology have been implemented till now. This paper aims to...
