Rubis 3 Auxiliary Power Unit

The Rubis 3 Auxiliary Power Unit (APU) 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.

Pneumatic power that is essential for quickly starting the main engines

Air-flow rate required to operate the air conditioning system of the cockpit and avionics

Electrical power over the on-board network, supplying power to a number of items of aircraft equipment

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.
