Describe the downwash angle of a finite span wing and induced drag coefficient!
Calculate Induced Drag please
The Antonov An-225 is the heaviest aircraft ever built, with a maximum takeoff weight of 640 metric tonnes. It also has the largest wingspan of any aircraft in operational service.
Sea level standard day (sls) conditions for calculations are 15°C; 101.3kPa
Rotate speed (Vr) at takeoff (sls):
Vr = 154 kts = 1.2×Vmin
(1 kt = 0.514 m/s)
Cruise Engine Thrust :
a) Calculate the lift coefficient for a standard day takeoff
b) Calculate the drag coefficient at cruis
Fcruise = 0.85 Fmax
Engine maximum thrust:
Factual,max = Fsls,max×δ θ½
δ = Pactual/Pref; and
θ = Tref/Tactual
