@@devilterminals7039 yeah but it's been 10 years for playing vice city.... that is the most difficult mission in whole vice city.... I feel very happy for completing that mission
I understood how the rear rotor and swash plate controls worked. But this video gave a glimpse into how difficult it would be to gracefully control a helicopter in practice. Then throw in variable cross winds and it must be a brain twister until it becomes second nature. New respect for these chopper jocks who do the amazing flights.
As an engineer, we all have the responsibility to carry knowledge to our next generation. Thanks for creating this video. A very good material for beginners and kids! Thanks.
Fascinating mechanisms and an explanation of gyroscopic precession exceeding two classes'. Your videos are consistently outstanding, raising my pledge.
While going through US Army rotary wing flight school in the early 90's my instructor pilot said helicopter pilots fly by constantly correcting for mistakes they just made. Difficult at first but an absolute blast to fly (OH-58 and UH-1's)
Your explanation supports me in my thought, that helicopters feel like a videogame - becoming as good with the controls as you can, clunky at first, but improving by the hour. I would like to make the helicopter licence one day, I just need to make some very good money for that. =3
Yes it is very expensive, especially compared to fixed wing (planes) which is still significantly higher than when I was flying in the late 80's through the 1990's. Best of luck in your goal, it's a good career path.
So lucky. My eyesight relegated me to just learning civilian helicopters in the 90s. Still, the best times of my life. Learning to fly a rotory wing machine is a real challenge.
Kinda like walking.. where you are actually falling in the direction you are moving but, by taking a step forward, you prevent the fall from happening. Ok, I was just trying to be clever😄
Close enough. Another analogy is that the helicopter is your enemy. You must anticipate all the time to win. Plus, they are magic. There aren't any helo mechanis.😁
It's incredible! There are years I tried to understand some things explained here, and these are told in a very simple way. Congratulations, great job ☺
Nicholas Roge Pretty sure it's robotic. The people who make these videos are engineers from IIT I think and would have an Indian accent most likely. Also the robot mispronounces things sometimes, like "Patreon." Whatever software they use is pretty solid, though, I don't mind the voice at all.
the other problem is that advancing in any direction via roll or pitch means the rotor lift isn’t facing perpendicular to gravity so more collective/lift is needed to counteract it. As well as that, when going down the rotor speed can increase to the point where the tips will break the sound barrier and slow down again roughly 50 times every second, resulting in a devastating loss of control and extreme noise. worst case scenario could involve the rotor blades snapping off or the control rods breaking because of the increased lift. Finally, those rotor blades have to be damn strong and slightly bendy due to the outside of the rotors going much faster than the inner side, meaning the outer edge creates more lift. Either a variably shaped aerofoil can be used with less lift ability on the inside or the rotors must be extremely flexible.
Been flying helicopters in vr somewhat recently and it's so much fun once you get the hang of it! Learning how it works also helps me figure out how to work it
this is the most explained/ concise/ clear cut and easy to understand video on the RUclips about the working of a helicopter. thumb up to the producers. will definitely support on patreon.
Finally a video that actually explains how it maneuvers. I was thinking, “there’s no way they rapidly change the pitch of the blades to lean a certain direction” but I stand corrected and in awe. Very cool.
Since i was a kid, helicopters have been my favorite vehicle, everytime i see them, my heart is filled with joy, but now i understand how they work, it make me love them more
The direction the swashplate tilts relative to the cyclic is actually determined by how the pitch links are rigged. Most modern helicopters have the pitch links rigged in such a way that they automatically adjust for gyroscopic precession/phase lag so that the swash plate can just tilt intuitively relative to the cyclic controls.
that's great. but the phenomena behind (gyroscopic precession) cannot be eliminated, responsible for all rigging or other approaches to make swash plate tilt intuitively relative to the cyclic controls. For beginners demonstration in this video will help them build solid understanding, isn't it?
On the first day of flight school in the army, during aerodynamics class, the instructor asked, "what makes a helicopter fly?" I raised my hand, knowing nothing of aerodynamics, and answered correctly, "funding."
Another factor to be taken into consideration when moving from the hover and transitioning to forward flight is the relative speed of the blade moving forward (the advancing blade) in the same direction as the helicopter and the blade on the opposite side of the rotor disc that is moving backwards (the retreating blade). Lift is generated by the shape of the aerofoil, the area of the aerofoil surface, the angle of attack and the speed through the air. In forward flight the advancing blade has its speed added to the forward speed of the aircraft and the retreating blade has its speed subtracted. Unless corrected, this would cause the helicopter to roll over as far more lift would be produced on one side of the disc compared with the opposite side. This is controlled at the rotor mast head by allowing the advancing blade to move backwards slightly relative to the rotor disc spin and the retreating blade to move forwards. Thus less lift is produced on the advancing blade, more lift is produced on the retreating blade which evens out the lift on both sides. This adjustable movement is controlled at the blade root.
that’s why the dual rotor design is more robust. With the chinook’s contra-rotating rotor sets, they both produce lift on opposite sides and it almost cancels itsself out. beautiful.
Luis My last name is none of your business Actually its the same thing: W/S for thrust. Mouse for the ring (tilt forward/backward/sideways) and A/D for the Tailrotor. Only direct up and down is done with the mouse in the basic position and more/less thrust. So I think in general not as different ;)
The Last Phoenix That's easier that in battle field. You can do it with one hand, without using a mouse. However, to aim it to hit a target is a different story. I agree.
I think I have to watch this video again. Not that something is wanting in this brilliantly illustrated video. It is my limitation. The Collective of the engineers who developed helicopters over decades deserves my salutation. Swash plate design is simply marvellous.👌👍

That's the point of the bearing, no? If it's a ball-bearing, then the two parts of the bearing will just roll against each other, which has minimal friction (at least theoretically).
@@Joe.Navarra Definitely, but don't you think it would still wear extremely quick? Unless they have some type of fluid system running through all that, then I guess I could understand.
@@joshuat20k I would imagine it is full of oil & then sealed. I'm not being facetious, I'm also just trying to understand.

samip science like a moment but not in equilibrium, and like force but instead of F=MA, T=angular acceleration * moment if inertia. Moment of Inertia being an objects resistance to rotation. If and object has a is starting to rotate in a direction the torque is written as in the direction of the right hand rule
They have the blades turning the wrong way for Airbus Helicopters (formerly Eurocopter). Blades are never at a negative angle of pitch, they are merely at a lesser positive pitch.
People are talking about how amazed that are about the difficulty of flying a helicopter. Imagine a windy day right on final on a Cessna 172. You use basically the same as a helicopter. Bank, power, and rudder.
