is the 675 SHP a engine limitation, or an airframe limitation?
Would have been decided at type design stage. An engine prop combination is chosen to deliver the power required. Consider that thrust horsepower isn't engine horsepower.
The STC from Texas Turbine changes the original Type Certificate and would have had to satisfy FAA about the changes.
Fuel flows from Boost pumps to EDFP to FCU to Flow Divider to fuel nozzles. The fuel pressure is developed by the engine driven fuel pump and the FCU, it isn't high pressure like a diesel engine.
Blocked fuel nozzles could give hung start and or low power.
Although have found partial blocked nozzles on servicing them without any defects recorded in flight log.
How does it find its way equally to all of the nozzles....? Like how does the first nozzles not end up with more pressure, while the top ones end up with next to none?
Basic physics, "pressure is exerted equally and undiminished......".
Would this damage the burner can by having an area that is not burning?
Damage to the can would be caused by "streaking" from partially blocked nozzle, don't know about damage from total blockage, but would think not.
