DEVICE TO JETTISON HINGED FUEL TANK Russian patent published in 2013 - IPC B64D37/12

Abstract RU 2492118 C1

FIELD: transport.

SUBSTANCE: invention relates to aircraft engineering, particularly, to jettisonable hinged fuel tanks. Proposed device front and rear jettison assemblies with parallel turning axles to set hinged fuel tank at an angle to drone airframe lengthwise axis. Rear jettison assy comprises two equal-length pivot levers with two swivel axles at their ends. Front swivel axles are secured at hinged fuel tank structural elements at equal distance from said front assy while rear pivot lever axles run in bearings attached to drone airframe. Note here that the length of rear jettison assy pivot axles is smaller than that of front jettison assy pivot lever.

EFFECT: higher safety of from fuel tank jettisoning.
