How does one get better thermal efficiency from a jet engine with elevated fuel temperature?
Is this another myth which we should refer to the Myth Busters?
Recalled incidents from last century.
USN Neptune about to break long haul record from Perth in Oz to some place in USA took on pre-cooled 130 octane Avgas so that tanks would hold more fuel weight. It took off still venting.
Then a DC4 was filled normally at same place and started venting as it stood on hot ramp/tarmac. Some idiot put some bungs in the vents trying to stop venting. Bungs not removed for start up and take off. Booster pump suction was enough to collapse integral wing tanks which trashed a pair of wings.
