willedoo Posted September 5, 2015 Share Posted September 5, 2015 A British drone enthusiast has built a helicopter with 54 drone motors. http://www.rt.com/uk/314394-man-builds-helicopter-drones/ 2 Link to comment Share on other sites More sharing options...
Head in the clouds Posted September 5, 2015 Share Posted September 5, 2015 Um - no, he's built a man carrying drone that has 54 electric motors without cyclic or collective functions. A long way from being a helicopter, as the video shows. Good try but ... 1 1 Link to comment Share on other sites More sharing options...

Good try but ... Drone An unmanned aerial vehicle (UAV), commonly known as a drone, and also referred to as a remotely piloted aircraft (RPA) by the International Civil Aviation Organization (ICAO), is an aircraft without a human pilot aboard. helicopter a kind of vertical-lift aircraft, capable of hovering or moving in any direction, having a motor-driven, horizontal rotor. So it's not a plane and it is not a drone as it is carrying a man. I reckon helicopter is a pretty good description. Just because the control system is different does not mean it is not a helicopter, in my opinion. Link to comment Share on other sites More sharing options...

So it's not a plane and it is not a drone as it is carrying a man. I reckon helicopter is a pretty good description. Just because the control system is different does not mean it is not a helicopter, in my opinion. Yes, I know what you're getting at, and that this contrivance is technically a helicopter but sadly it's doomed to failure as far as being a practical aircraft. There's good reason why helicopters have collective pitch control in particular, and cyclic control also. Power changes just don't cut it when it comes to quick and precise changes to lift requirements, or directional requirements, as can be seen by the mushy drifting up and down and inability to arrest the descent (imagine it trying to stop a high rate of descent) and the poor positioning control even in nil wind conditions. The idea of power variation with fixed pitch airscrews to control lift and direction was tried extensively using gangs of petrol engines and eventually abandoned due to the throttling response rate being far too slow for effective control. Electric motors certainly have a great advantage when compared with petrol engines in a similar configuration, because electric motors produce full torque regardless of rpm or load, even if fully stalled (i.e. prevented from turning), so their response to changed power settings is very quick, but not nearly quick enough for a practical helicopter unless the power to weight ratio is massive. And that massive power/weight ratio is why scaling model drones into person carrying vehicles just doesn't work. The drone's performance is beyond dramatic and impressive but as the weight comes up to person-carrying size, the motors and batteries must increase in size to the power of 4 to keep the performance similar. 2 1 Link to comment Share on other sites More sharing options...
willedoo Posted September 6, 2015 Author Share Posted September 6, 2015 It makes you wonder if the builder was seriously trying to design something workable, or if he's just an eccentric hobbyist. 1 Link to comment Share on other sites More sharing options...

Gnarly Gnu Posted September 6, 2015 Share Posted September 6, 2015 It makes you wonder if the builder was seriously trying to design something workable, or if he's just an eccentric hobbyist. He seems the quintessential old British backyard inventor. I'd like to see a weaponized version in a Bond movie. 1 Link to comment Share on other sites More sharing options...

Kiwi303 Posted September 19, 2015 Share Posted September 19, 2015 I guess they have never heard of ear and eye protection. Or head... I wouldn't want to stand up under the disc! It looks far too low, unlike normal commercial copters with the rotor height 8 to 10 feet off the ground, that looks lucky to make 5 feet. Link to comment Share on other sites More sharing options...
facthunter Posted September 19, 2015 Share Posted September 19, 2015 Rotary wing and fixed wing are defined flying machines. Vectored thrust is another. VTO and land. I thought a drone is remotely controlled of the essence. Nev Link to comment Share on other sites More sharing options...
eightyknots Posted September 23, 2015 Share Posted September 23, 2015 I think he may just be a member of the Rotary Club having a good time. When this "helicopter" pilot reaches the maximum altitude of about 15 feet, he will be eligible to join the Apex Club. Link to comment Share on other sites More sharing options...
