Abstract
Dismountable aeronautical pod device 30 with cryogenic storage capacity, for external transportation by an aircraft, comprising a front cryogenic tank 36, a rear cryogenic tank 37, and at least one central temporary storage tank for the rise in pressure of the gas supplied by the front cryogenic tank 36 and the rear cryogenic tank 37.
Claims15
A dismountable aeronautical pod device with cryogenic storage capacity, for external transportation by an aircraft, comprising a front cryogenic tank, a rear cryogenic tank, at least one central gasification and temporary storage tank for a rise in pressure of gas supplied by the front cryogenic tank and the rear cryogenic tank, each cryogenic tank, both the front and rear, has a convex outer shape, and comprises an inner casing defining a storage chamber, an outer casing containing the inner casing, an isolation chamber defined between the inner casing and the outer casing, and a removable manifold passing through the outer casing and the inner casing in a sealed manner, and a pipe fed by the manifold, and the temporary storage tank having a quasi-toric or quasi-annular shape.
A dismountable aeronautical pod device with cryogenic storage capacity, for external transportation by an aircraft, comprising a front cryogenic tank, a rear cryogenic tank, at least one central gasification and temporary storage tank for a rise in pressure of gas supplied by the front cryogenic tank and the rear cryogenic tank, comprising a compressor arranged downstream of a downstream valve, said compressor being active at an end of an emptying phase to bring the pressure in the temporary storage tank to a value lower than a lowest value of the pressure in the front cryogenic tank and in the rear cryogenic tank, and a pressure regulator arranged downstream of the downstream valve, said pressure regulator being active at a start of the emptying phase to bring the pressure of the gas at an outlet to a value lower than the pressure in the temporary storage tank.
