The power required to overcome drag in flight mechanics is often referred to as “Drag Power” or “Power Required.” It represents the amount of power that the aircraft’s engines must produce to counteract the aerodynamic drag that opposes the aircraft’s forward motion.
Power Required = 1/2 * ρ * v^3* s * CD
ρ (rho) is the air density.
- v is the true airspeed (actual speed of the aircraft relative to the air mass).
- CD is the coefficient of drag, representing the aerodynamic drag characteristics of the aircraft.
- S means wing area
