Question

A Propeller driven aircraft is flying at sea level, the given data are power available is Pa = 150000 watt, Weight=2500 Newton, K-0.05 and Cp, o=0.01 and S=12m2 density=1.225 kg/m3 calculate maximum velocity of the aircraft? Also find maximum load factor when V=40m/s in above?

be carefull with the unites ,

Answer 1

for units just take as it is given it will automatically will be set as watt is equal to joule per sec which is equal to kg m^2 / s^3 so when other units are multiplied automatically velocity m/s will be reached

LA 150000 watt Weight: 2500N K-0.05 (po = 0.01 S: 12 m2 Density = 1.225 kg/m² Vmax = ? nmax when V = 40m/s . na Chastas PA - T.V V= PA PA qas Co, odk v= PA 18v2 S CeroXK 2 V3 = QPA 0.5XSXSXC60 = 2 X 50000 0.5 X 1.225 X/2 X 0.01 v = 159.81m/s
