Although the Crecy had great potential, insurmountable problems stymied its development. After R-R wisely threw in the towel to concentrate on gas turbines, Ricardo soldiered on but to no avail. Accor ...

Two-stage R-2800s used this system, i.e., the main (2nd) stage being a fixed speed and the auxiliary (1st) stage being variable speed via a fluid coupling. These included -8s (F4U-1), -10s (F6F Hellca ...

Kip - you can recognize the DC-4 oil cooler by the fact it's round. The DC-6 oil cooler is oval shaped. I have a DC-6 oil cooler converted to a coolant radiator on my IV-1430.

This design allows for a one piece c/case. Offy used this design concept for their Indy 500 engines.

Regarding prop strikes, the FAA mandated that if the crank run-out (direct drive) or prop shaft run-out was within prescribed limits the engine could be returned to service.

I read the 3500hp claim as well. I would take it with a grain of salt. As you know, the ‘45/’46 AWA is full of errors and this is not surprising considering the sheer volume of information available i ...
