FOCUSED WAVE VALVELESS PULSEJET ENGINE - the 'Short Lady'
The scale working drawing, as disclosed on 14 Sep 2004. The engine was designed 
to be fabricated entirely from mild steel tubing and sheet steel, with fully welded
construction. The first prototype was built by high school student Steve Bukowsky
of Connecticut, USA. I did not show engine mounts on the drawing.
