I was thinking about the force that balances the force of gravity in a drone, and I stumbled upon this question that how to mathematically describe the upthrust being generated by the propeller, as a function of the angular speed of the propeller and the angle of bend of the propellers.
Here's what I know:
- Integral factors for the upthrust generated should be the angular speed of the propeller as well as the angle of bend and the size of the propeller, though I am not sure if there would be any other factors playing there role too.
- I know that the propeller would be sucking the air from underneath the device from a laterally-half-toroid path around the propeller, and then creating a pressure difference, which would cause air to strike the bottom surface. Multiplying this pressure with the area of the bottom surface would give us the upward force on the device.
Here are a few links answers I referred, but couldn't get the exact answer:
