A simple theory which explains the concept of flying.
This video is about Bernoulli’s Principle. This principle was introduced by Daniel Bernoulli. People have always perceived that flight was possible from observing birds, but it took thousands of years to actually achieve and there were so many hurdles along the way. Flying can be defined as controlled movement through the air and includes sustained, controlled and powered flight. And flight is the actual process of flying.
How do we control flight?
Three axes control the flight of an aircraft: – Yaw, Pitch and Roll. Moving parts of the wing, tail plane and fin surfaces change the camber of these parts and affect their lift and drag. And forces are provided to change the aircraft’s path.
- Rudder controls Yawning (left/right)
- Elevators control pitching (nose up/down)
- Ailerons control Rolling
Bernoulli’s Principle: –
Bernoulli’s principle helps explain that lift can be achieved by an aircraft because of the shape of its wings. They are shaped in such a way that air flows faster over the top of the wing and comparatively slower underneath. The aircraft is pushed up by the high air pressure underneath the wings through the lower air pressure.
The aircraft is pushed up by the high air pressure underneath the wings through the lower air pressure.
The Wright brothers have applied Bernoulli’s principle for the first time to predict lift on an airplane wing.
