Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a power booster for a gas turbine engine, and more specifically, to a control device for a power booster.

What is the power booster of a gas turbine engine? 11! ! In order to do so, one or more flame holders should be placed upstream of the flame carrier.
Richi distance 1111-111i! A radially extending bar located within the exhaust duct also includes a plurality of fuel spray pipes (in the form of concentric rings).

The flow rate of fuel flowing through the smoldering 1' supply color is constant and predictable. Making a power booster
During transient operation 111- of the r'+ III and booster, the shut-off valve is opened in sequence and the main fuel control valve is also opened, thereby allowing the unhold operation to proceed according to a predetermined schedule J-. The amount of fuel supplied to the fuel tank is increased.

The flow of fuel sprayed from each fuel frost pipe is tr! is back f1
The back pressure suddenly increases when the shutoff valve is shut off. 2 changes, and as a result, the flow of fuel flowing through the fuel 1'i+ +1r1 fog pipe that has already been sprayed with fuel becomes extremely low (and also increases and fluctuates.Thus, Marhold l\\ inflow / Ji) The fuel flow rate is J to the main fuel control valve.
During transient operation of the booster, the distribution of fuel to each fuel spray color is not uncertain.

It is an object of the present invention to provide an improved fuel control system for a gas turbine engine extender.

Another object of the present invention is to provide another fuel spray 'J' for the booster.
