R975 Radial engines

Very interesting but kinda ugly, John, unless you're into the steam punk look.
No shrouding on the cylinders and no sign of the huge fan on the tank engines so how's he going to cool it, especially the lower 3 cylinders?
And try ordering at Timmy's.

I will go with you there Malcolm, it's not green and has no tracks...so besides some kind of engineering exercise seems like money wasted to me...and as for the Timmys drive thru I have begun a petition to widen those damn approaches and raise the menu board to commanders cupola height as tank drivers can never get even the simplest coffee order correct

They did a real interesting feature on an episode of Jay Leno's Garage on the truck, and you're right Dennis just an engineering exercise, no real function to it

I apologize to Bob for sending his very interesting and informative thread off a cliff

(PS: so far just one signature Malcolm, driver claims I have insulted his cognitive ability...)

Meanwhile, back to the thread. Here's the helicopter version of the engine, as talked about earlier. Continental R-975-46A being field changed in RCN HUP-3 "946" in the High Arctic. Summer 1955 transit of northern waters from BC to the Maritimes. Flew off #50 Labrador as part of proving trials to see if helicopters could be deployed on smaller sized ships. This lead to the invention of the the "Bear Trap" and successful deployment of the Sea King helicopters on RCN destroyers. Larry Zibitnew RCN Archives. (Go Navy)...grin...

Oops...obviously 246..

Great pictures Dennis!
can you imagine having to change an engine with equipment shown... lots of fun! Just like winter camping.
I believe one of these helicopters resides in an aviation museum near Ottawa.
Tims comments always welcome!

My exact thought too. How the heck does he cool it....? Looked it up. Short answer is ..no cooling. Gary Corns says he runs it about 10 to 15 minutes. Before it gets too hot and he shut's it down. It's a Showboat..
