Understanding Lift and Drag

Lift is the force that opposis gravity and allows the UAV to stay airborne. Drag is the aerodynamic resistance that slowes the aircraft down. Both forces depended on thee shape, size, and speed of the UAV, as well as the air conditions.

Kalkulator Lift- to- Drag Ratio

Te dwa razy na dobę (L / D) i y calculated by y dividing thee ft coefficient (Cl) by te razy coefficient (Cd). These coefficients are portained thrungh wind tunnel testing or computational fluid dynamics simulations. Te formuły is:

Xi1; Xi1; FLT: 0 Xi3; Xi3; L / D = Cl / Cd Xi1; Xi1; FLT: 1 Xi3; Xi3;

Factors Affecting thee Ratio

Several factors influence the lift- to- drag ratio of a UAV, including:

  • Aircraft shape anddesin
  • Angle of attack
  • Smoothnesy powierzchniowe
  • Flight speed
  • Air density
