It is a cryogenic fluid
that can cause rapid freezing on contact with living tissue.
Air Liquide (Paris:AI) announced on Wednesday the signing of several contracts for the supply of cryogenic equipments for the propulsion of the future European launcher Ariane 6, as well as for the design and production of the cryogenic fluid
systems of the new Ariane Launcher System (ELA4) of the Guiana Space Centre.
The cryogenic fluid
is delivered in bottles under a compression of 6 MPa in liquid condition.
Liquid nitrogen is a commonly used cryogenic fluid
, used in food freezing and preservation, plastic and rubber grinding, inerting and blanketing, heat treating atmospheres, and tire inflation.
Once upon a time Mr Freeze was dedicated scientist Dr Victor Fries, a home-loving boffin who went violently off the rails after his wife became terminally ill and he fell into his own vat of cryogenic fluid
For bending tests, samples were immersed in cryogenic fluid
(nitrogen) and quickly (no longer than 5 seconds) placed on the same device that was used for bending at room temperature on the INSTRON testing machine.
The portable unit stores 15-liters of cryogenic fluid
in its dewars reservoir, gasifies it, and delivers 40 [ft.
This is the coldest cryogenic fluid
(-269[degrees]C/-452[degrees]F) and has a very low latent heat of vaporization of about 9 Btu/lb.
The SV91 series of valves provide maximum cryogenic fluid
throughput with minimum pressure drop.
Using its state-of-the-art cryogenic fluid
and system technology, Whittaker Controls intends to bring the two technologies together using advanced materials and manufacturing capabilities, including insulation technology derived from the space shuttle program, to design, produce and market the advanced LNG nozzle as markets for LNG vehicles emerge and grow.
The future owner~s remit will cover - Conventional and cryogenic fluid
systems different sets of launch (type Ariane, Soyuz, Vega)- Fluid systems test benches (type BEAP)- Fluid systems of the entire payload preparation (EPCU)- Fluid systems in Guyana means of production (plant LOX / LH2, propellant factory)- Networks of transmission and distribution.
Will be affected by this agreement:- Complete mechanical assembly of cryogenic arms and paneled MANG- Flexible or rigid lines for cryogenic fluids
and conventional fluids that will be positioned on the arms and in the caissons- The portion control command that can be used to qualification testing phases- The set of qualification tests to validate the different functions of the Sol / Edge interfaces.
