Drag From Glide Angle Calculator

Drag is the aerodynamic force opposing an object’s motion through a fluid, such as air. It acts opposite to the direction of the object’s velocity, reducing its speed or causing resistance. The glide angle has a direct impact on drag force in gliding flight. As the glide angle ($\theta$) increases, the component of lift acting opposite to the direction of motion (perpendicular to the glide path) also increases. The formula to calculate Drag is as follows:

Where:

• $D$ is the drag force in N,
• $L$ is the lift force in N,
• $\theta$ is the glide angle in radian.
