A helicopter of gross weight W with rotor diameter D hovers at Sea level achieving a figure of merit M using momentum theory calculate the % of change in actual rotor power at 1 KM above sea level at same M density change 8% per KM may be assumed near sea level
If the % increase in power required for a helicopter to hover at an altitude above sea level is 6% higher that required to hover at sea level with the same figure of merit, determine the altitude. Assume that the density change is 8% non KM
