Last Sunday, a friend of mine who is a project superentnedant for a large A/C company in Davie Ivited me to watch a Helicopter lift 42 heavy A/C unites up on a 2 story roof. The company Pirate Helicopter has a Sikorsky S-58 Aircrane. This machine has a max load lift capacity of 3500 pounds, depending on weather conditions. we were talking with the Pilot about the engine. It had a Radial, Curtis Wright R-1820-84 Cyclone radial engine.a monster, which he gladly opend the front and showded us. The engneering was really something, when you think this machine was built in 1954! It was internaly supercharged. Front mounted engine.
It was 1525HP.......He truned it as high as 2750rpm's under heavy load, it burnes 100LL, at 2 gal. a minute while working, and JUST 1.5 gal. a min while crusing at 90 MPH....TBO is 600 hours at $36,000. The main gear box cost $40,000, and goes for 1000 hours....It took his 1 hr 20 min to lift all 42 units.....When He lifted the heavy unit, and the pilot gunned the motor, that was a powerfull sound ill tell ya,,badmofro
