Really excellent work, you even got the 90 degrees out of phase for blade lag. One minor comment. Your blafe pitch was the wrong way around, collective up, all blades pitch up, yours go down. Easy enough fix. Blades are generally symmetrical on helicopters, except for the Chinook.
His model has trailing edge pitch horns. With this configuration, collective control up would have to cause the slashplate to move down, pitching the blades leading edge up. This would be reversed for leading edge pitch horns. It would have been better to refer to swashplate movement- up and down for collective pitch and tilting for cyclic pitch-as there is no connection between the cockpit controls and the rotor head in this model.
I agree. Blade grip linkages should have to be installed forward the blade grips. His configuration inverses the Pitch up with collectives sticks all the way down.
@@stumpusMaximus I mean yeah, sort of....still nothing quite like this...he designed a pretty basic crank powered air screw.. State of the art at the time, but just this rotor alone is about as complex if not more. With DaVinci, the complexity of the engineering wasn't that impressive, but rather it was the genius of developing the concept itself to begin with, being so unfathomably unique for the time. It was impressive what he did, but IMO, had he not been quite the isolationist and could have collaborated with some people more skilled in materials and engineering at the time, he may well have created something that excelled on all fronts...not just concept.
In most RC helicopters the ball joint at the blade fork is on the leading edge, not the trailing edge. this inverts the operation of the collective: in your diagram the swashplate goes down to increase pitch, in most RC helis the swash raises in order to increase pitch. Also, your head rotates counter-clockwise from above wheras the convention is to rotate clockwise. you can solve both problems at once by simply installing mirror image blades.
I'm a senior researcher at Heimkeeper Co., Ltd.Our company has an idea to reduce propeller noise and vibration of helicopters and drones.We're done with the experiment.We have applied for a utility model and a patent As a result of several experiments with small propellers, the current noise and vibration reduction effect is about 30%. Looking forward good news from you soon
Finaly i saw a video that explain's how it work's. I was asking my self the last year's and was thinking how it could work but was to lazzy to google it. Look's like it was pretty similar how i thougt it would work. Thx oh whise YT alorithm for recommending me that xD
Often yes, but not for this design. This rotor head is using a negative advance angle, so the swashplate must be LOWERED to increase the pitch angle. Long explanation: - Negative advance angle: the pitch horn attaches to the trailing edge (rear) of the blade: LOWERING the swashplate pulls the back of the blade down, raising collective pitch. - Positive advance angle: the pitch horn attaches to the leading edge (front) of the blade: raising the swashplate lifts the front of the blade up, increasing collective pitch. Some real helicopters (e.g. the B105) use a negative advance angle, while others (e.g. the R44) use a positive advance angle.
The vast majority of helicopters have the pitch change links connected to the leading edge of the blades so that raising the swashplate causes increase in blade angle of attack. The only types that I know with the pitch change links connected to the trailing edge are the Bolkow 105 and the Hughes 269. The rotor head from the 269 was also used on the McUlloch J2 autygyro, and possibly on a few other autogyro designs.
Very well done ! However, I never saw rotor blade holder with a screwed lever. My helicopters do have this in one piece. Is it an engineering idea of you or did you reverse engineering at an existing model ?
Lot's of people here wanting to make their own helicopter from a simple animation that shows 3 axis push/pull interactions. But in the real world there is something called friction, and another thing called resonance, and inertia, and gyroscopic force, and mechanical moments. And about 20 other factors that need to precisely balance to overcome gravity without dropping yourself 4 meters and crushing your spine, or having your body sliced into primal cuts of meat by a whirling blade that goes out of track due to a miscalibration, or one of multiple fasteners flying apart because just one of those failed. Come to think of it. Building your own helicopter, could help solve global overpopulation.
Excellent video. The multi-rotor (quadcopter) Drone technology has really simplified this now, but this was the technology for its day. Of course, this needed a tail prop to compensate for the drag and help in steering.
The tail rotor is mainly used to compensate for torque produced by the main shaft trying to spin the helicopter body in the opposite direction of the rotors. This is why a heli with a damaged tail rotor spins out of control.
Basic requirement: i5 (or higher) 500 GB Hard disk or SSD (for high speed SSD is preferred), RAM 8 GB (16 GB- if dealing with analysis & large number of parts), Graphics Card 4GB ( NVIDIA Quadro K2200 or any SW Recommended)
yes it's costly But! if u don't need to use SW for any heavy projects ( including more than 100 parts & lots of analysis involved ) then this configuration is still enough: i 3 or i 5, 500 GB Hard disk, 4-8 GB RAM, 2GB Intel Graphics Card
@@SolidworksFunPraveenSingh thanks mate, I really really appreciate that. And what kind of gpu? Quadro I guess. Will the same config work on maya, inventor, 3dsmax etc too?
GPU ( it's useful when u have to work on very complex project & render any simple or complex animation) , otherwise CPU is sufficient. For Maya, 3dsMax You will need GPU to quickly bake & render high quality animation.
I'm confused; I'm seeing the blades pitch down when the collective is raised on a counterclockwise rotating system. . .? I understand this is supposed to be an RC helicopter, but either I'm crazy or the blades are not pitching correctly.
The majority of helicopters have a rotor speed around 200rpm. The Westland Gazelle has 380rpm and the Westland Scout and Wasp have rotor speed of 400, with a potential 410 maximum. I believe that this is the highest rpm of any helicopter design. Most helicopters have some means for the pilot to adjust rotor RPM within a few percent of the nominal.
I used ti work with a company that did a lot if work with helicopters. I used to provide support in 2 different helicopter factories. Learned a lot how they flew. Your pitch lower section works fine but I fail to see the upper blade movement following the same inclined plane. Am I correct?
It's an eye opener for me to know the rotor blades of a helicopter is being controlled. Is it possible to to 3D print these parts of required dimensions to incorporate the same in a model. Is the STL files of the parts provided in the video since I am watching this in my android mobile.
@@SolidworksFunPraveenSingh please make a tutorial on how to create solidworks animation like how in the starting all the components were joining together.
I'm not big on helicopters, I got pretty good at flying them in the simulators though, yeah I don't like those rotor heads, they look really problematic and dangerous to me with a lot of possible failure points, what kind of lifespan do they get out of those things? Yeah that main rotor shaft has to endure the entire weight load of the vehicle and everything it's lifting along with aerodynamic forces against the rotors and the body of the helicopter, with all those little moving parts around that thing seems really dangerous and something you typically try to avoid doing in engineering.
Absolutely perfect video, however, the deficiency in the video is the voice of a human. I think it should not be too hard to explain it in words instead of silly heading. This deficiency prevents me from watching this video.

Почитал комментарии , видно что ещё есть грамотные люди . Не всё ещё потеряно . Анимация отличная за исключением мелких ошибок . Благодарю всех 🙏👍
The best video about rotor head I have never seen
It is so complex that it's a miracle every time an helicopter flies without crashing on the ground.
Just think that Leonardo da Vinci had drawn the first helicopter in the 15th century
That miracle is called a "Pilot".
Its amazing how your fan works without crashing😂

Beautiful! A work of art.
Great video and animations as always but I wish it portrayed the helicopters motion relative to the swashplates position better.
lower servo arm => increased pitch in animation

Merhaba kolay 3 adet servoyu aynı anda hareket ettirip sonra ayrı ayrı birbirinden bağımsız hareket ettiren bir sistem varmi teşekkür ediyorum
Great works that's good but please which software did you use to make animation after motion study with many sequences
Wou keren sir teknologi
This makes my RC heli roll pitch and yaw.
Very cool! 🤙
I'm confused; I'm seeing the blades pitch down when the collective is raised on a counterclockwise rotating system. . .? I understand this is supposed to be an RC helicopter, but either I'm crazy or the blades are not pitching correctly.
there should be 2 rotating scissors for dynamic stability(vibration)
Grate work !! Can I have these cad files if don’t mind?
Is interesting how described this function, when I was a child forever ask me, what did the blade do to move? Interesting
What is the RPM of a helicopter rotor? How fast do helicopter blades spin?
in this animation, 10 RPM was taken.
The majority of helicopters have a rotor speed around 200rpm. The Westland Gazelle has 380rpm and the Westland Scout and Wasp have rotor speed of 400, with a potential 410 maximum.
