ND­-450

FULL NAME

PUMP­DOZER 450

 

DESCRIPTION

It is intended for automatic control of fuel supply into engine AI­450 by two basic channels of an electronic control system and fuel dozing into the engine proportionally to a location of the engine control lever in reserve hydromechanical control mode.

Pump­dozer provides:

• increase of fuel pressure in pumping stage of pump­dozer;
• Increase of fuel pressure In main stage of pump­dozer;
• fuel supply to start­up engine nozzles;
• fuel supply to operational engine nozzles;
• engine turn­off: mechanical or by electric command;
• fuel filtration;
• signalization of pressure drop in fuel filter;
• limitation of minimum and maximum fuel consumption;
• fuel dozing by electronic regulator command during operation of the main control system;
• transition to reserve control system by electric command;
• throttle characteristic GT =f (α руд) during operation of reserve control system;
• characteristics of acceleration and release GТ =f (t) during operation of reserve control system.
