More Book Details

Description of the Book:

Powerplant studies were conducted for a shaltdriven, heavy-lift helicopter (HLH) with design gross weights ranging from 75,000 to 85,000 lbs and a maximum payload capability of 40,000 lbs. The number of engines required, the gross weight, and the fuel consumed for specified missions using various powerplant configurations were determined. Control system studies were conducted to investigate control modes, power train dynamics, and multiengine control and load sharing. Power coupling studies were conducted which included combining and reduction gearing, cross shafting, clutches, and gas-coupled rotor drives. The results of these studies indicate: use of regenerative engines will result in fuel savings on all missions; approximately 18,000 shaft horsepower (sea level static rating) may be required; current multiengine control techniques are applicable to the HLH; and a gas-coupled rotor drive system warrants further investigation
