Induced Drag as a
function of bank angle, assuming a constant altitude and speed
Scot,
"Aerodynamics for Naval Aviators" states that a constant angle, constant speed coordinated turn produces a certain load factor which requires increased lift and increased thrust/horsepower. Further, the change in thrust is due to change in induced drag. Generally, induced drag varies as the square of Cl. Thus,
Load Factor = Secant of Bank Angle
Percent increase (from level flight) in induced drag =
100 x ((Load Factor squared) - 1)
Example:
45 degree banked turn, Load Factor = Secant(45) = 1.414
Percent increase = 100 x ((1.414 x 1.414) - 1) = 100 x ((2) - 1) = 100%
