When I use GS-23 gun engine RPM drop

[Skulleader]

Hi,

When I press "space bar" for using the GS-23 gun the engine RMP drop.

In fact this effect appear when I press the "GSH-23 ARM / SAFE" button, each time that I press "space bar" or the fire triger for my HOTAS the engine RPM drop, when I release the "space bar" my engine RPM rise to 100%.

 

Is it one bug or from me ?

 

Thanks, Skull.

Hi Skull. This is how it works in real bird:

FUEL DELIVERY LIMITER

 

The fuel delivery to the engine is continuously cut down to

protect the engine from surge when the gun is firing. Once the

armament system is selected and ready for gun firing, the fuel

delivery is limited the whole time when the trigger is

squeezed either the gun fires or not.

 

WARNING:

 

If the trigger is squeezed for more than a few seconds,

the RPM will drop down to 42% either the gun fires or

not. When the trigger is released, the RPM increase

back to preselected value by the throttle.

It works this way in real bird, however it decreases engine N1 (HPC) speed not up to 42% but up to flight idle. Minimum ground idle is 56%+-1.5% N1 and flight idle can be higher as it increases with altitude according to original technical manuals.

This also happen when fire the gun pod.
