And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.
If you have never seen or heard a radial engine powered helicopter you need to find a way to see or do that. A ride would be Devine, so many moving parts so much that could go wrong. Brave souls all.
Was it true that this helo was developed around the fact that there were so many surplus C-47 engines from WWII.....that they needed somewhere to use them?
No. The reason was these engines were simple, powerful enough and most importantly reliable. They went 400 hours between overhauls, but overhauls could be done in a jungle dirt strip by line mechanics...overnight. The best example of a original S-58 is in the US Army Aviation Museum at Ft. Rucker Alabama. It flew President Dwight D. Eisenhower- a first. Fun facts to know- A UH1 can fly using diesel for fuel (instead of JP4). BUT only for ten hours. The engine must then be pulled and sent to the factory for overhaul. You best have a VERY good reason to do that $$$$.
I think the UH-34 had a similar engine. 9 cylinder rotary gasoline engine. Something like 1820 cubic inches. It was a work horse of a helicopter in Viet Nam.

ReplyDeleteThe Sikorsky used a Wright R1820 (B-17 engine). The C-47 used a P+W R1830.

ReplyDeleteSmall correction. It is a radial engine, not rotary. A rotary is like the original early Mazda engine.
DeleteUH-34: Helicopter Utility Support. The origin of the phrase "HUS Me Out" "Help Me Out"
DeleteThe turbine conversions of that helo was pretty slick looking under that cowl.
