Real flight in phun

Helicopter built with phun. Notice how it falls when I turn air friction off, is really just using air.

10 rotors with 3 blades and 3 engines each, 1 on 955 RPM and 2 on 477 RPM. The outer blades rotate at half speed to match horizontal position and make force only on down turn.

The concept was based on this video:

And here is a slow motion detail of rotor working:

Continued

The rotors, since they obviously cannot benefit from Bernoulli's principal, have a system that makes the lifting rotor components vertical in up take, and horizontal on down take. This, compounded by a large number of rotors (it doesn't have to collide with anything) gives it the required lift to pull the helicopter from the ground. And before you ask, no, I doubt the helicopter is at it's pre-set mass of 2 Kg/m.

Perfect. That is nothing to do with "real world flight", but its a way that make phun objects to "lift", at least at that phun version. I believe it still works for newer versions.

I cant remember now the total mass of the helicopter, but its very very light indeed. It COULD work for heavier objects, but it would take a larger number of more and more rotors, making the final result look anything but a helicopter =)

anyone who says that this is not real is just a noob who doesnt understand physics

[stargayt]

can you make it better?Low tech...it's a simple tech for low computers.Who has procesor for simulate bang of nuclear bomb?You?

[uplusion22]

All you need now is turn ability on the rotors, a slight one though. have two bricks or circles be invisable on each side of propellers, allowing it to turn, but not fully around, only 20* angle. and then have a motorized hinge on each prop. E.G. _ _

.|. .|. Propellers, horrific text drawing....

@betochperu perhaps, but the physics behind it are sound, like someone doing the breaststroke, with less friction on their arms pushing forwards than when pulling themselves through the water, causing them to move forwards, this helicopter uses the same principles as far as I can tell, just with air friction.

@JaXNashphun phun is for noobs

do u think any cientific has used phun for a real experiment??? pfff

[FlightSimx97]

That is one of the best things I've seen in Phun, it makes me wonder since there is air friction you can use it to climb. Oh and how are you tilting the heli? Is it a weight onboard or is it diffrent amounts of power on each engine?

[turbopiemel]

yo bitch gravity is on are u blind?

[legodude121212121212]

gravitys on

[RaysOfPivot]

just cause gravitys of.

[killerdavesullo]

LOL!!!

[ugotpwnd321]

tilt your head to the right and look at it lol

[killweb2]

holy hell
