Drag is nothing but a force. It opposes the glider's motion through the air. Drag is produced by almost every part of the glider. As it is generated by the interaction and contact of a solid body or liquid (air or water or gas), it can be called a mechanical force.
Drag is expressed by the following formula:
Drag comes in a few types, such as parasites drag, skin friction drag, induced drag, interference drag, total drag, form drag, and so on:
- Parasite drag: Parasite drag is the resistance of the air to the glider moving through the air. The drag on the wing is very low if we consider a standalone wing, but when calculated for the whole ...
