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.
With being a radial engine, did they have a heat build up problem? I know with them being on aeroplanes that takes care of that problem but being surrounded with tank armor I would think that armor would be a heat sink. How many cubic inch displacement and it's horse power rating, any body know?
The R-975 in the HUP-2 Powerplant: 1 × Continental R-975-46A 9-cylinder air-cooled radial piston engine, 550 hp (410 kW) Most radial engine cubic inches matched the engine number R-975=975cu in +-. More here lots of tank stuff if you scroll down. https://www.usautoindustryworldwartwo.com/continentalmotors.htm
according to Army Ground force archives the air cooled engines highest failure rate was caused by poor quality fuels causing detonation and piston failure.
That makes sense we used 115/145 avgas in the helo and checked the fuel before fueling and the fuel tank daily for water. In the three years with the HUPs that I deployed with we never had an engine failure.
Shouldn't the tank commander's hatch be on the right side of the turret?
ReplyDeleteThe same engine, Continental R-975 Radial Engine, that powered the M-4 Sherman tank powered the HUP-2 helicopter.
