Anyone have a handle on the efficiency of inter-coolers or the the temperature differential between input and output temperatures. Cold dry air is best for efficiency of combustion and hence output power. Show us the data please.

Curious - What's the consequence if this wasn't discovered and the beam failed?
Would the engine depart or would it severely damage the engine?

Factory intercoolers are around 30% efficient, AA intercoolers around 70%. This is per AA.
Yep, engine would depart the aircraft. I don't know if that's ever happened, though.

I think you meant would it depart the aircraft or just be severely damaged. I'm guessing it'd be severely damaged either way...

True. One does not typically return an engine to service after it falls off an aircraft.
It is always possible the engine might not fall off the plane, crazier things have happened. But the concern of course is the engine falling off, which is why you don't want to mess around with it.

I was referring to a Twin Cessna, not a 727.
Heh. Someone asked what would happen. I just linked to a photo showing it happens to even the best...

Yeah, especially if the lav dump shoot seals are leaking and blue ice forms on the aircraft exterior, and the engine has a catastrophic failure due to fod.

This brings an entirely new meaning to the radio call "Northwest forty five sixty two, we just lost an engine".

A number of engine-shedding events were precursored by blue-ice shedding events, which proves... sometimes the **** really does hit the fan. ;-)

No brown trout have been reported to have squeezed through a 727 lav dump shoot seal.

Yeah but it's more fun than saying the pee hit the fan. Plus, at least some fecal matter made it through, even if the entire trout didn't swim downstream. Hahahaha.

Since we drifted to 727's... they have two large "doughnuts", an upper and lower, that are part of the forward engine mount fitting. Replaceable vibration isolators (either elastomer or wire mesh, "metalflex") mount into the "doughnut".

Reminds me of a saying we old Range Rover owners have. "If it's not one thing, it's two"
Thread creep! I am searching for a photograph showing a C-47 flying the hump from Burma to China. One engine departed the C-47 and can be seen falling to the ground. The photo is a lucky shot taken from another C-47 flying in trail. Saw it once, haven't been able to find it again....
