Introduction to thrust, weight, lift, drag, and cruise
Any system that is planned to be in the air is characterized by the physical forces that act upon it in a 3D space, that is, the X-, Y-, and Z-axes. On Earth, the force that pulls an object down is the force of gravity, which has to be overcome first when seeking flight. The force of gravity acts the same towards all objects on Earth, pulling them at an acceleration of 9.8 m/sec2. When taking this into consideration, all objects have their weight associated with this process, which is acted upon by the force of gravity.
When taking Newton’s third law into account, every action has an equal and opposite reaction. The drone experiences a force that is equal and opposite to the force of gravity acting on the body. Let’s see the various terminologies associated with this and how we can cater to it.
Thrust
Thrust is the reaction force produced by the rotation of motors and propellers in the drone. This force acts...
