Horse Power and its Effectiveness

[Dave Williams]

-> Guess why there are NO piston engined aircraft that use the diesel
-> cycle??  Because they do not rev high enough.

 Imagine all those car-engine-conversion fools wasting their time with
speed reducers to keep the prop tips from going supersonic...


-> torque that an airplane neads...!  IT IS SIMPLE  1 GALLON OF DIESEL
-> HAS ABOUT 2/3RD MORE BTU'S THAN A GALLON OF GAS!  More energy before
-> = more energy converted to mech!  K.I.S.S.

 BTUs aren't the whole scenario; internal combustion engines are
slightly different from heating your house.
