Aerodynamics and Flight
Aerodynamics is the way how air moves around things. Rules of aerodynamics explain how an airplane is able to fly. Aerodynamics is related to airplanes and the concept of flight. In other words, it is a study of concept of airflow and its principles or study of how gases interact with moving bodies.
The principle of aerodynamics can be used in various fields including building of bridges, automobiles etc. Aerodynamics is being used in automobiles for a long time.
All physical objects on our planet are subject to gravity but gravitational force is not the only one which keeps them attached to the ground. The air itself prevents the lift.
There are four forces of flight: –
- Weight: – Everything on this planet has a weight. This force is cause by gravity which pulls the object down. The weight of an object is a major factor in determining that how strong the push needs to be?
- Lift: – Lift can be defined as the push needs to be applied to move something up. This force is opposite to the weight. To move an aircraft upward, more lift is required as compared to the weight.
- Drag: – Drag is a force that tries to slow the object down. It becomes harder to walk or run through water than air because air causes less drag than water.
- Thrust: – Thrust can be defined as a force that is opposite to drag. It is a push used to move an object forward.
