Opale 3

Opale 3

The Opale 3 Auxiliary Power Unit meets all of the needs in terms of secondary power in the M-346 training aircraft developed by Alenia Aermacchi.

The Opale 3 makes the aircraft totally self-sufficient for starting and ground operation, and contributes to operating safety by providing additional main engine restart capabilities in flight.

Its remarkable compactness, combined with a power output among the highest in Safran Power Units range, makes the Opale 3 an APU particularly suited for the most demanding applications, in terms of integration as well as performance.

In a small space, it 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
