Actually that was the real deal. A prototype was built in 1941.

The engineers on all sides were really coming up with some
creative solutions.

Subject: [FlyRotary] interesting cooling idea
While
looking around on the web for info on Rhino I came across these models of an
airplane labeled an FW-802. I don’t know if it was ever real, a prototype, or
nothing more than an artist conception. But a pretty intriguing idea.
