Abstract
An aircraft comprises a hydrogen-fuelled propulsion system, a plurality of like generally cylindrical hydrogen storage tanks and a conveying system arranged to convey hydrogen from the hydrogen storage tanks to the hydrogen-fuelled propulsion system. The aircraft further comprises a fuselage having a cargo bay () including one or more (A-G) of the plurality of hydrogen storage tanks, the longitudinal axes (A-G) of the one or more hydrogen storage tanks within the cargo bay extending parallel to the longitudinal axis () of the fuselage and lying in one or more planes () extending across the width dimension of the cargo bay. The hydrogen storage tanks within the cargo bay have a common aspect ratio R in the range 4.2≤R≤25.7, allowing the volume of space with the cargo bay occupied by stored hydrogen to be maximised or approximately maximised.
