All i know about them at this stage is that they are carbon fibre blades light weight and very strong.
But obviously not worth purchasing if they are going to adversely effect the flight of the drone.
Im no aeronautical engineer so have no idea what the effects would be but at a guess im thinking higher thrust at lower motor speed would be one of the effects.
Aloha Hellsgate,
As noted by KYK, there are many complex issues involved in giving the Phantoms three blade propellers. The old Huey helicopters from the Vietnam War had two blade rotors and have now been redesigned and rebuilt to have three blades. They are now part of a team with Apache gunships used as a ground support strategy. The old Huey helicopter had a characteristic sound and now the new Huey sounds completely different and is much quieter, although not as quiet as the four blade Apache gunships. The quietness is the most beneficial improvement. Also, the rotor disk is much smaller so it can operate in tighter environments.
Now apply these concepts to our quadcopters. They would have a smaller rotor disk which means less propeller in photos and videos when the Phantom is pushed hard. The three blade rotors, if designed appropriately, can also be quieter. But for these improvements, the motors and ESC will need work to maintain the energy consumption of current Phantoms and not increase wear on the motors. It is an interesting engineering exercise and opens discussion on many other design possibilities.
Hope this helps!
Aloha and Drone On! |
