Steve considering the original purpose of these Aircraft
Engines. It should not come as surprize on the amount of redundancy designed into the airframes aswell as the engines themselves.

Some examples would be that once ignition occurs you may remove all the electrical devices and yet as long as they receave fuel and air they will continue to run.

If Airframe mounted fuel lift pumps should see failure the
Fuel System on the Turbine continues to draw fuel.

Pretty neat Stuff.

Our new 714 engines are pretty complex in design, but easier to operate. The best part is the FADEC system which is basically an automated digital control system. When we start up, it even shuts down automatically if a hot start is suspected.

I don't know about the whole removing the electrical devices thing, but we can lose the FADEC system and it goes into a reversionary mode. If that mode fails, then we just land. We could likely still fly, but it's just easier to land as soon as possible.

The fuel pumps are actually in the tanks, along with the engine driven fuel pump. We can still fly below 6000 ft PA with the fuel pumps inoperative because the engine driven pumps are so efficient.

The entire aircraft is pretty complex, one of the reasons I love it so much. I like tinkering with things, so it was a perfect match for me when aircraft selection came around. To us, all other aircraft are nothing but slingloads!

I'll take a pic of us fully armed when I get out to the flight line tomorrow. Pretty impressive. Now flying while the gunners are engaging gets the adrenaline going quickly!

I think there should be a forum section for tubine powered boats no matter what brand. What do you guys think? Doug

Check out Turbine Marine... John has an "on the fly" flush system, press the little button under you throttle finger and it flushes the motor while running, plus a 10% boost in power as the air gets dense... nice one.

Good idea my rinse is located on a momentary switch on the dash.

I like reading about this stuff too...Though I am still waiting to see what the answer was to my question about the water injected exhaust. How does this help muffle the sound? Seems all the newer boats are going this way.
