Problems solved by technology

Therefore, this scheme was found to be insufficient for supplying cryogenic liquid with reasonable accuracy and at a temperature significantly higher than the original temperature of the cryogenic liquid before it was heated
Also, this does not supply the pump with liquid at a constant temperature over time

Embodiment Construction

[0017] Such as figure 1 As shown, the supply device 1 in one embodiment of the present invention includes a cryogenic storage tank 1 for receiving liquid hydrogen 2 , and the supply device is used to supply liquid hydrogen with controllable temperature and pressure to the test bench 4 . As an example, the test stand 4 may be designed to test the cooling and / or operation of elements of a cryogenic rocket motor, in particular a pump for supplying propellant to such a rocket motor. It can also be used to test such engines as a whole. However, the apparatus and method of the present invention can also be used to test other types of cryogenic devices.

[0018] At the bottom of the cryogenic tank 1 , the tank has a liquid hydrogen extraction point in the form of an extraction pipe 3 connected to a test bench 4 via a valve 5 . However, the extraction line 3 can also be connected via a further valve 6 to the first tank 7 of gaseous hydrogen. The cryogenic storage tank 1 is also for...

Abstract

The invention concerns a method of reheating a cryogenic liquid contained in a cryogenic tank (1) with a gaseous ceiling (18). Said cryogenic liquid is heated by injecting a warmer gas under a free surface (17) of the cryogenic liquid.

Description

technical field [0001] This invention relates to heating cryogenic liquids, and more particularly to heating cryogenic liquids stored in storage tanks having head gas spaces. Background technique [0002] In some cryogenic applications, especially technical testing and scientific experiments, it may be necessary to supply cryogenic liquids at precise temperature and precise pressure conditions. For example, when testing cryogenic rocket engines, especially when cavitating the pumps they use to feed cryogenic propellants, there is always a need to more frequently supply a flow of cryogenic liquid close to the saturation point. In order to limit the wall thickness and thus weight of the tanks of the vehicles propelled by these rocket engines, the trend is to reduce the pressure inside the tanks. Therefore, the liquid supplied to the feed pump during actual firing is close to the saturation point, whereby the phenomenon of air bubbles in the pump is more likely to occur. So i...
