1946 vintage pulse jet run 4th of July.
Fuel is gasoline. Starting by compressed air and Ford Model T
spark coil. Pulses resonate at 240/second. Static run is limited to 30
seconds due to heat generated. 80 cc gasoline is consumed in the run. When mounted on U control model airplane speed ship, kicks along at 200mph!
As youngster, I would ride bicycle by Detroit, Michigan model shop
drooling over Dyna-Jet engine displayed in window.
