氢浆的应用技术

Applied Technology for Slush Hydrogen

空天飞机(NASP)是水平起飞、着陆的单级入轨飞行器。由于氢具有高热值和高冷却能力,而被选作为燃料,但它的低密度性导致飞机体积庞大。与之相比,氢浆提高了密度和热沉,显著地减小了飞机的体积和重量。本文概要介绍了氢浆在生产、贮存、稠化、输送、抽吸、增压、热力声频振荡、测量等方面的技术问题以及迄今的研究成果。

The National Aerospace Plane(NASP) is a horizontal takeoff and landing, single-stage-to-orbit vehicle. Hydrogen is chosen as the fuel because of its high energy content and relatively large cooling capability. However, the low density of hydrogen results in a large vehicle. Both the fuel density and cooling capability are increased with the use of slush hydrogen and so the size and weight of the vehicle can be significantly reduced. This paper describes generally the technical problems and research results of slush hydrogen in production, storage, solid fraction upgrading, transfer, pumping, thermal acoustic oscillation and density measurement.
