kaz3g; You got any info on just what transpired with that project? And why it has not proceeded?
Folks,
Because, over many years, CAA/CASA stalled the "auto tug" program. Why?? Because they could, despite US experience.
There are thousands of aircraft flying behind "auto" engines, ranging from certified engines (many based on a Mercedes alloy block) through many V-8 powered smaller ag. aircraft in US, and the largest number in Experimental" aircraft.
There are some "interesting" engineering issues, particularly engines based on the Chev. "small block", these are well known and understood.
For those of you pontificating on proposition of potential propeller problems --- what, in heaven's name do you think reduction gears/drives are for??
Tootle pip!!
PS: Alvis radials were extensively used in military vehicles, plenty of boats with Merlin (Meteor) and Allison V-12s.
