Power supply for military aircraft

Your needs

Ensure the supply of energy to military aircraft (planes or helicopters) when parked:

  • 400Hz power
  • Fuel
Also ensure the possibility of transferring computer data between the aircraft and the information systems of the air base.
Include additional connectors for ancillary equipment.

400Hz aircraft power supply

  • Ensure a sufficient and compliant power supply for all types of aircraft.
  • Through a system that disappears into the ground when maneuvering, and is small enough not to risk any contact with the aircraft when deployed.
  • Ensure that the installation complies with international standard ISO6858

Fuel supply

  • Through the hydrant network at the base
  • Provide access to the underground network for maintenance teams.

Data transmission

  • Through the wired network for data security.
  • Ensure the cyber security of the aircraft.
