Guillotine system, in particular for an in-flight refueling device

A guillotine system, in particular for an in-flight refueling device, comprising:

• a passage configured to have a pipe pass therethrough,
• a blade movable between:
• a first position, in which the pipe slides freely through the passage, and
• a second position, in which the blade is configured to cut the pipe, and
• an actuator configured to move the blade from the first position to the second position,
• wherein said actuator is of the non-pyrotechnic type and is configured to contain and/or generate a pressurized fluid released to move the blade from the first position to the second position, the actuator comprising an accumulator configured to contain a volume of pressurized liquid, the system further comprising a monitoring unit configured to allow a monitoring of a state of the actuator, and the accumulator comprises a first internal cavity configured to contain the pressurized liquid, and a second internal cavity configured to contain pressurized gas and/or an elastic return member, in particular the first internal cavity and the second internal cavity being separated from one another by a membrane, in particular one which is movable and/or deformable.
