There is no doubt that artificial intelligence draws more an more attention from people all over the world, drones are widely used now, they are keeping optimizing, refining and intelligent. Are you confused about the four, six or eight rotor wings of commercial UAVs drones
? The number of rotor wings decides what? Appearance? Flight speed?
The influence of stability: Basically, for stability, we can say that stability of eight rotor wings is better than four rotor wings and four rotor wings, more wings is with better stability. Its reason is obvious, for an air vehicle with certain kinetic characteristic, more controlling factors will get better effect. Four rotor wings air vehicle is a system without drive. Six rotor wings air vehicle is a complete driving system. It is more complicated but it is worthy if it can get better effect. The another advantage that is not easy to notice, more rotor wings, tolerance for air vehicle to disabled dynamic system is higher. After all, a engine of several air vehicle does not work suddenly is common. For model-level air vehicle, shooting oar is a common thing. On this occasion, eight and six rotor wings can bear double engine failure and one engine failure, they are also under control. However, if one engine failure occurs to four rotor wings, the cheap UAV drone
will fall down unless there is cyclic pitch on wings.
Geometric dimension: With the increase of rotor wings, it will have a bad influence on its geometric dimension. Because more wings , shorter distance between every wings. Four rotor wings is put every 90 degree, six rotor wings is put every 60 degree while eight rotor wings is put every 45 degree.
