1.1 This specification covers wrought carbon steel sleeve type pipe couplings suitable for joining carbon steel pipes.

1.2 Type I couplings are intended for use on all schedules of pipe where the pipe wall thickness does not exceed the wall thickness of standard weight pipe. Type II coupl...

This paper is to promote investigation into the nuclear rocket engine (NRE) propulsion option that is considered as a key technology for manned Mars exploration. Russian NRE developed since the 1950s in the former Soviet Union to a full-scale prototype by the 1990s is viewed as advantageous and the ...

The unbalanced impedance of the asymmetric 3-phase wind power permanent magnet synchronous generator (PMSG) compensated by external circuits in series with the 3-phase windings is investigated in this paper. The asymmetric impedance includes the unbalanced resistances, unbalanced self-inductances, a...

A novel structure of axial flux stator and rotor dual PMs Vernier machine is presented as an effective option for high torque-density direct-driven applications. The key is to locate PMs on both sides of rotor and stator. With dual PMs, this proposed machine with a novel structure generates an impro...

In this paper, the case of a battery charger for electric vehicles based on a wireless power transmission is addressed. The specificity of every stage of the overall system is presented. Based on calculated and measured results, relevant capacitive compensations of the transformer and models are sug...
