AI Technical Summary
Existing hydrogen storage systems for aircraft face challenges in achieving lightweight, thermally insulated tanks that can withstand the demanding conditions of high-altitude flight, including geometry, temperature, permeation, and hydrogen embrittlement, while efficiently storing cryogenic fluids.
A double-wall tank design with an inner and outer chamber separated by a vacuum gap, featuring a flexible fluid channelling system with bellows and bushings to absorb relative displacements, and using composite materials like FRP for reduced weight and improved insulation.
The design minimizes structural loads and maintains fluid-tightness, offering high insulation efficiency and reduced weight, suitable for long-term hydrogen storage in aerospace applications.
