You tube video link of the two motors running on test stands from a 2007 UK show and some text re the motors from the comment section.
the left engine is a griffon, the right one is a merlin.
The Griffon is a 37 litre V12 engine with power ranging from about 1700 to 2400 hp. It was used in a number of military aircraft.
The Rolls Royce Merlin is a 27 litre V12 engine which came in many marks from, say, 1936 to 1947. It was used in a number of aircraft during that period, mainly military. Power ranged from 900 to well over 2000 hp. The Meteor is a downrated Merlin, without supercharger etc. Power is about 650 hp. It was used in Centurion tanks.
Q: does anyone know how the contra props worked? i can never find anything about it.
A: On the front of the engine there is a gear case that split engine power to two concentric shafts. The gears have a herringbone pattern to them. One set of gears powers the rear prop, the other the front. The gears receive full pressure oil at all times of engine operation.
They aren't props mate they are engine run load paddels, they put load and flywheel effect on the engine but produce very little airflow. They are about half the size that would be fitted in an aircraft for flight.
