Factors that increase Thrust of the CR Flight Drone Motors in Grams/Watt
- The motor runs much cooler as the stator is spinning creating an axial compressor effect and blowing air around the motor at a much higher than normal rate.
- We are creating a null point at the point of attachment to the drone which eliminates the resultant torque and vibration of the motor. 10%. This is a very conservative estimate.
- Counter rotation from a standard single prop gains about 15% but loses the 15% in driving the gears. In our technology we have no gears so it is free power. The CR Flight motor uses a slip ring to power the motor this allows both the Stator and Rotor to rotate. With the counter rotating motor which is a reactive drive rather than an active drive, by definition each propeller has to supply half the drive. Because of this required balance between the two props, theoretically the swirl caused by the front prop is exactly countermanded by the rear prop giving a straight flow characteristic with maximum thrust, eliminating the loss from prop swirl. This effect has been researched extensively by NASA and other aircraft manufacturers and they always agreed on about a 15%+ increase in performance. The difference is that on a standard counter rotating prop set up, it is gear driven so although you gain the 15% in performance, you lose about 15% in gear losses. Consequently you only used this technology if you wanted more speed and were not concerned with loss of efficiency. We gain the performance gains without any of the losses. This is caused by straightening the air flow from a 5-30 degree angle based on the power being used. This gives a resultant vector of about 10 -30% more velocity in the direction of flight. 15%
- Longer bearing life. This is standard knowledge. 2%
- We are using a larger prop at a lower RPM which increases the efficiency of the prop thrust to watt usage by another 10-20%. 10%
