Abstract: An organic composite gas storage tank 300 comprises a hollow central portion 306 which is substantially cylindrical and formed integrally with first and second end portions 302, 304, and which defines a longitudinal tank axis 301. The first end portion comprises a hollow truncated conical region which meets the hollow central portion at a first end thereof. The hollow central portion comprises first and second hollow truncated conical portions 306A, 306B, the external radius of a given hollow truncated conical portion decreasing in a direction towards a corresponding end portion. The tank comprises an organic composite fibre winding extending between first and second positions along the length of the tank which coincide with the first and second hollow truncated conical portions of the hollow central portion respectively, biassing these portions together and increasing the axial strength of the central portion.

Abstract: A hydrogen-fuelled aircraft 200 comprises a fuselage, wings and a plurality of cylindrical elongate hydrogen storage tanks mounted on the exterior of the fuselage and disposed vertically above a plane containing the wing-tips of the aircraft. An aerodynamic fairing forms a continuous air-washed surface of the aircraft together with a lower portion of the fuselage. The hydrogen storage tanks extend generally parallel to the fuselage and are contained between the fairing and the fuselage. The aircraft provides for storage of a large volume of compressed hydrogen without compromising the volume of usable space within the fuselage. The aircraft is able to carry out flight missions comparable in range and payload to those of an equivalent conventionally-fuelled aircraft.

Abstract: An organic composite gas storage tank 100 comprises a hollow central portion 106 which is substantially cylindrical and formed integrally with first and second end portions 102, 104, and which defines a longitudinal tank axis 301. The first end portion comprises a hollow truncated conical region which meets the hollow central portion at a first end thereof, the outer and inner radii of the hollow truncated conical region decreasing in a direction along the longitudinal tank axis away from the hollow central portion. An organic fibre winding 107 extends at least between axial positions which coincide with the hollow truncated conical region of the first end portion and the hollow central portion respectively. The first end portion has a higher axial strength than that achievable for hemispherical end portion of a tank of the prior art.
