Rubis 3

The Rubis 3 Auxiliary Power Unit has been designed to meet the on-board power requirements of the Dassault Aviation Rafale multi-role combat aircraft, powered by Safran Aircraft Engines M88 engines.

Able to start the main engines on the ground or in flight, the Rubis 3 provides the aircraft with autonomy and increased safety.
The Rubis 3 has benefitted from continuous improvements since it came into service in order to exceed the needs of the customers in the most severe environments and conditions of use.

Providing power among the highest in the Safran Power Units range, the Rubis 3 delivers:

  • the pneumatic power that is essential for quickly starting the main engines,
  • the air-flow rate required to operate the air conditioning system of the cockpit and avionics,
  • the electrical power over the on-board network, supplying power to a number of items of aircraft equipment.
