TUBESTRUCT integral high-pressure tube tank The basic idea is a single-tube structure of a wing, where the tubes are loaded under high internal pressure as well as able to absorb thrust and torsion loads from stresses in the flight. The tubes can absorb hydrogen, methane or other volatile gases.

摘要

Summary Technical Problem of the Invention = Technical Problem and Objective The innovative nature of TUBESTRUCT is to exploit the utility of green hydrogen as an energy source without the drawbacks of conventional hydrogen tanks, which are either at the expense of aerodynamic efficiency or payload capacity. So far, although tubular tanks have been used to store the hydrogen already, the adoption of structure-carrying functions has not yet been carried out in modern high pressure tanks. The development of the state of the art through the project TUBESTRUCT consists in the first combination of these two functions with the aim to gain an aerodynamic and capacitive advantage. Solution to the problem or technical problem The basic idea is a single-tube / single-cell structure of a wing, where the tubes are loaded under high internal pressure, and can absorb thrust, bending and torsional loads from stresses in the flight. The tubes can absorb hydrogen, methane or other volatile gases under high pressure (up to 700 bar). Application area TUBESTRUCT enables the use of hydrogen in small aircraft / general aviation aircraft. This is a significant increase in range possible. In addition, the CO2 emissions of such aircraft are eliminated and the overall eco-efficiency of aviation increased.
