Abstract

The high temperature superconducting (HTS) contra-rotating propulsion (CRP) systems comprise two coaxial propellers sited on behind the other and rotate in opposite directions. They have the hydrodynamic advantage of recovering the slipstream rotational energy which would otherwise be lost to a conventional single-screw system. However, the cooling systems used for HTS CRP system need a high cooling power enough to maintain a low temperature of 2G HTS material operating at liquid neon (LNe) temperature (24.5 - 27 K). In this paper, a single thermo-syphon cooling approach using a Gifford-McMahon (G-M) cryo-cooler is presented. First, an optimal thermal design of a 1.5 MW HTS motor was conducted varying to different types of commercial 2G HTS tapes. Then, a mono-cryogenic cooling system for an integration of two 1.5 MW HTS motors will be designed and analyzed. Finally, the 3D finite element analysis (FEA) simulation of thermal characteristics was also performed.

用于电力推进的组合双1.5 mw高温超导电动机的紧凑集成冷却系统

高温超导(HTS)对旋转推进(CRP)系统由两个同轴螺旋桨组成，它们位于另一个螺旋桨的后面，并在相反的方向上旋转。它们具有恢复滑流旋转能量的流体动力学优势，否则传统的单螺杆系统就会失去这种能量。然而，用于HTS - CRP系统的冷却系统需要足够高的冷却功率来维持2G高温超导材料在液态氖(LNe)温度(24.5 - 27 K)下的低温。本文提出了一种使用Gifford-McMahon (G-M)冷冻冷却器的单热虹吸冷却方法。首先，针对不同类型的商用2G高温超导磁带，对1.5 MW高温超导电机进行了优化热设计。然后，设计并分析了用于两台1.5 MW高温超导电机集成的单低温冷却系统。最后，进行了三维热特性有限元分析(FEA)仿真。
