Originally, engine control systems consisted of simple mechanical linkages connected physically to the engine.

The FADEC System – Electronic Control Unit (ECU)

When standing alone, the EEC makes all of the decisions until the pilot wishes to intervene. Jet engines and aircraft gas turbines. If you wish to contribute or participate in the discussions about articles you are invited to join SKYbrary as a registered user.

Stanly 11 1 2. The following transmit inputs to the control channels across the low-voltage harness:. Engine Fire Protection Systems.

True fxdec authority digital engine controls have no form of manual override available, placing full authority over the operating parameters of the engine in the hands of the computer. The inputs are received by the EEC and analyzed up to 70 times per second.

Manifold pressure sensors 4. Kind of like the fadrc in a digital computer. Sign up or log in Sign up using Google. In Rolls-Royce and Elliott Automationin conjunction with the National Gas Turbine Establishmentworked on a digital engine control system that completed several hundred hours of operation on a Rolls-Royce Olympus Mk The goal of any engine control system is to allow the engine to perform at maximum efficiency for a given condition.

The system was an evident improvement over mechanical control but had its drawbacks, including common electronic noise interference and reliability issues. Engine operating parameters scu as fuel flow, stator vane position, air bleed valve position, and others are computed from this data and applied as appropriate.

The control channels are independent, and there are no shared electronic components within one ECU. This procedure can be repeated for any other phase of flight.

EGT sensors Figure Components Propeller governor Propeller speed reduction unit.

The inputs are received by the EEC and analyzed up to 70 times per second. With the operation of the engines so heavily relying on automation, safety is a great concern.

True full authority digital engine controls have no form of manual override available, placing full authority over the operating parameters of the engine in the hands of the computer.

An ECU is assigned to a pair of engine cylinders. The FADECs now apply the calculated takeoff thrust setting by sending an electronic signal to the engines; there is no direct linkage to open fuel flow.

In flight, small changes in operation are constantly made to maintain efficiency.
