Re: Helicopter Project
hovering is actually the most challenging aspect of this auto pilot project.
When the HC starts to hover the downdraft of the blades will push the air straight down. After a few seconds the air will start to swirl in a donut pattern, the air that was being pushed down goes outward, then back up, and is then sucked through the blades again. the result is, the air at the center of the HC developes a downward velocity. In order for the HC to maintain its height you must apply more and more pitch/power. So you are going to need a way to measure altitude in order to hold a fixed altitude while hovering. |
