When the Alta X is ripping across the sky at 75mph there is a phenomenon called 'Dissymmetry of lift'. ⁠⠀
⁠⠀
This refers to the idea that the blade that is advancing in the direction of flight is seeing a speed that is equal to the rotation speed + the forward velocity. The advancing blade creates more lift than the retreating blade.⁠⠀
⁠⠀
It is important for vibration and stability that lift across the rotor blade is balanced. Drones that do not use ActiveBlade will exhibit higher vibrations and lower stability. ⁠⠀
⁠⠀
Our ActiveBlade design compensates for this dissymmetry by reducing the angle of attack on the advancing blade, increasing it on the retreating blade, and balancing lift across the disk.⁠⠀
⁠⠀
This leads to the Alta X flying like a dream, the pilot smiling, the director complimenting, and the accountant being impressed with business growth.⁠⠀
⁠⠀
Ever wonder how this tiny, crazy company in Woodinville WA comes up with this stuff? ⁠⠀
⁠⠀
Hint - we do it because we are passionate about creating shots that were once impossible⁠⠀
