Airbuses IL-96-300


VGTD VSU-10 type - gas-turbine engine with free turbine rotating turbine-driven compressor and alternating-current generator through the reduction gear-intensifier.

VGTD VSU-10 is intended:

On the ground:

1) for manufacture and maintenance of airplane services by electrical energy;

2) for manufacture and maintenance of sustainers starting systems and conditioning of an airplane by compressed air;

In the air:

1) in the capacity of an emergency source of electrical energy and compressed air for airplane needs (in case of sustainers failure or their generators of an electric current) - production and supply of compressed air for sustainer starts and in airplane conditioning system, and also production and supply of electrical energy - to airplane airborne systems.


VGTD VSU-10 consists of following modules and functional systems:

- Gas generator;

- Reduction gear-intensifier;

- Driven compressor with air by-pass mechanism behind it;

- Alternating-current generator;

- Starting systems;

- Fuel supply and regulations systems;

- Oil system;

- Protective systems;

- Ice protection system;

- Control systems.
