In aircraft design, air brakes, also known as spoilers or speed brakes, are aerodynamic devices used to increase drag and decrease the speed of an aircraft. They are typically deployed to assist in deceleration, descent control, and to reduce the aircraft’s speed during landing or approach. Here’s the formula and SI units associated with air brakes:
- D represents the drag force produced by the air brakes.
- ρ is the air density.
- V is the velocity of the aircraft.
- Cd is the coefficient of drag for the deployed air brakes.
- A is the area of the deployed air brakes.
