Thank you so much.

[@someoneelse7629]

He was not the most straight forward teacher, but he made me understand the principle much better

[@raydreamer7566]

I have watched a lot of explanations on how gyro's work and this was the best !

[@BlueMax333]

an excellent explanation in a language that can be understood by the layman. Thanks, Abid!

[@CMBuchanan]

That's a great explanation of blade flapping / sailing where pilot error can result in a rotor to tail strike, however I believe Silverlight has a solution in the form of an audible alert system called the GWS (Gyro Warning System). The GWS also warns of other potentially dangerous mistakes pilots can make in a gyroplane.

[@stachowi]

great lesson

[@robh4671]

Excellent explanation 👍

[@lorendjones]

Very helpful! I've schedule some gyro lessons later this month and this has helped much understanding of the aerodynamics of the rotor. Thanks!

[@jamesschmidt5200]

Well done!👏

[@billgardyne7328]

Great explanation. Thank you 😊

[@ujungkulonpost]

Very good

[@irgtk]

You start your takeoff just like a Taildragger with the stick all the way back. Can’t wait to try a Gyro!

[@abidfarooqui-sla3301]

Exactly. You pre-rotate and then you go in the Cub mode before you ever move forward.

[@JMOUC265]

That was great. Very educational. Thanks for posting it.

[@irfanbaig6077]

Length of rotor blades?

[@antr7493]

very interesting. thx

[@AriVovp]

How about the reverse flow thing

[@andresuribe8765]

Thank you, that was a really simple yet complete explanation, I’ve never flown anything other than fixed wing but it’s pretty cool to understand how different flying machines work

[@ExperimentalAircraftChannel]

Thank You for taking the time to watch! :-)

[@CaptainSwoop]

Thanks. That was very helpful.

[@ExperimentalAircraftChannel]

Thank You. Much appreciated!

[@cameronlapworth2284]

pretty good explanation but you can still flap (hinge) the blades at full back stick as you are stalling the blades at higher a of a. too much airspeed compared to the rotor speed is key though.

[@earlsammesios8696]

Sir kindky ixplian how long,,inchis ,wedi of blade og gayro,plain sir ,,

[@lambendower5535]

Are autogyro main rotor use negative angle of attack during flight?

[@C_Franc2000]

una duda ,que tengo el rotor, de media, cuantas revoluciones maximo aguanta? actua algun tipo de freno, si supera x revoluciones? un saludo!!

[@cameronlapworth2284]

the teeter hinge also removes the effects of gyroscopic precession from influencing the control system. without teetering rotors gyroscopic precession would make it uncontrollable. anyone using a drill or even a hand held fan has noticed the 90 degree off set of action. as a of a changes only happen when the rotor head is certain positions the impact of the change in terms of precession only happens 90 degrees latter when the teeter hinge is aligned so it has zero impact on the controls. this is hard to explain in words but say you push the head forward at the moment the rotor is fore-aft as shown here. the rotor won't do anything as the head will tilt but the rotors are on a hinge on this axis. however as they progress around to side to side the head pitched down has tilted the rotor so the retreating blade has a higher a of a and the advancing has a lower a of a. the blade begins to tilt retreating up and advancing down starting to fly into a new plane of rotation. now on a fixed rotor this would impart a gyroscopic precession 90 degrees latter but as that is now fore aft again the precession not only cannot impact the control system but will be compensated by the teeter system equalling out dysentery of lift and it would be moving in the right direction anyway. this is why gyros are so manoverable compared to fixed wings thier rotors have little resistance to flying into a new plane of rotation.

[@gregc6661]

That was a brilliant explanation, thanks for a great video!

[@ExperimentalAircraftChannel]

Thank You! We learned something new as well!

[@drampadreg1386]

Interesting, even if there wasn't a single helicopter in the video

[@abidfarooqui-sla3301]

True but the flapping principle still is the same in helicopters. If you fly a R22 it still has a central as well as an offset flapping hinge and basics of equalizing lift remain the same there

[@ExperimentalAircraftChannel]

Sorry about that @Drampa Dreg. The conversation is the same for both Gyro and Heli. "Helicopter" happens to work better in the title else you may have not seen this video. :-)

[@phillipzx3754]

It you ever get the chance, go visit Jim Vanek of "Sport Copter." He's located in Scappoose, Oregon. He does loops in his gyro.

[@vuthytiv]

How meter this up fan?

[@prakashofficebloggerchannel]

What is this jaroplane and halecopter prices

[@ikay2102]

150 hours on gyrocopter, best flying experience ever. Everyone should try to fly one, will not go back to airplane again.

[@anthonyrstrawbridge]

👍♥️ Very nice. I question if, during cruise, the rotor has the potential to generate enough electrical energy to be useful enough for exploring the possibility of developing an electric propulsion design. If the rotor can maintain design speed while also supplying the additional load of an electric generator?

[@abidfarooqui-sla3301]

Interesting thought but nothing is ever free. Energy taken away for some purpose effects its other purpose (lift creation). How much? I'd have to think on that and may be its possible but no such thing as free lunch in general. The main problem with any electric aircraft is storage energy density. Simply put gasoline/chemical storage has 20 x more energy density than the best electric storage mechanism commercialized today. Also as we use gasoline, its weight reduces and electric storage holds the weight basically the same when its charged or when its out. Huge penalty in energy density and weight this way. Some clever/genius material scientists have to solve this fundamental problem before any electric aircraft will become truly viable. Hopefully this will happen soon. A lot of people working on it.

[@anthonyrstrawbridge]

Yes, your explanations are indeed correct. This is an excellent gyroplane and I would purchase it today for my own personal mission. I love the larger rotor blades and the highest power rated fuel injected turbocharged Rotax. I've visited the building and pricing schedules and am satisfied. Hopefully I'll have the resources and health in the near future to visit, fly, and participate in building one. No need for any modifications; except my unfamiliarity with this particular instrument panel would need to be addressed. I also wonder if floats are possible. I'm back to building a flying saucer for now. 🛸

[@markwebb8013]

Nice explanation of how rotary lift works.

[@ExperimentalAircraftChannel]

Thank You!

[@catthewondahokulea6515]

Awesome thank you for this video. I am trying to learn more about Air Craft maintenance. Still working my way through General Aviation Maintenance understanding. Spent a ton of time to make sure I understand the FAA laws, Airworthiness Directives and Upgrades and Modifications rules.

[@ExperimentalAircraftChannel]

Well keep at it! Thanks for stopping by!

[@parulparul6436]

What is your name sir

[@neal-stewart834]

seems like this pilot error with not pullig back the stick could have someone figure out a way to fail safe this by warning system or the like ??? mechanical electronic ?

[@abidfarooqui-sla3301]

Working on it. Check ... kzbin.info/www/bejne/h4eWmppoYrGda7c

[@chetmyers7041]

Design a simple microprocessor system that monitors the RPMs of engine, rotor, and wheels across ground, and possibly airspeed, and it could monitor the take-off run. It could sound an alarm for pilot to execute ABORT TAKE-OFF.

[@neal-stewart834]

@@chetmyers7041 yea ! my comment was off the top of my head and yea a solution is great answer

[@MrJdsenior]

These aren't helicopters. that is why they are called by a different name. I was soooo waiting for him to say "They are moving at very great velocipy", a la "number five is alive". I had an Indian Mechanics of Materials prof with an accent heavier than this fellow's, and he once said, perfectly straight faced "I am thinking about teaching English next semester". Everyone laughed, good prof, very smart.

[@adambryant2876]

Great information! Poor title. A helicopter's rotor blades do NOT work like a fixed pitch autogyro's blades.

[@copperone1590]

First of all I am not an engineer: but I do have a question, Have you tested a Kasper wing design in a rotor blade? The reason I am asking this is that back in the 1980's I met Kasper Wetol a Boeing engineer who created the Kasper wing ultralight aircraft, he asked me a simple question "what do you see when you look at an aircraft wing?" I made the motion with my hand as if it was going over the top of the wing, he said that is the problem nobody looks underneath the wing, he proceeded to explain that he asked the Boeing Department "HOW MUCH ENERGY DOES THE ARTICLE TEAL EXPEND ON ITS NONSTOP FLIGHT FROM POLE TO POLE", the answer came back that it (The Artic Teal) should not exist on arrival, we know it makes the flight every year without fail, he than asked me "do birds have square bones? well I said no! he replied than why do we put them in airplanes? he said look at the underside of an article teals wing? this is the proper design nature gave the Article Teal to conserve energy "THE SECRET IS THE UNDERSIDE OF THE WING". The magazine "SCIENTIFIC AMERICAN" in the 1990's ran an article on the Kasper Wing stating that if it (the Kasper wing) were to be installed on a Boeing 747 the plane could fly fully loaded at 35mph with no problems. an ultra light aircraft Kasper wing has been sold for a number of years. I have never heard of any aircraft company even attempting to test the Kasper Wing on an aircraft other than the ultra light, would you be willing to test a Kasper Wing (Rotor) design on one of your helicopters to see if it would enhance the flight capabilities?

[@ExperimentalAircraftChannel]

This is NEW to me. Nice story sharing what YOU know! Of course. Abid (The Engineer) didn't produce this video... WE DID. :-) But... you are more than welcome to reach out to him to start a conversation. The link to his website is found in video as well as a link in the description below. THANK YOU FOR WATCHING!

[@copperone1590]

@@ExperimentalAircraftChannel one thing i forgot to include is that the Kasper Wing is the only fixed wing aircraft that can land, as Wetol explained to me is that birds land airplanes fly in, the kasper wing when brought into a stall it can be lowered to the ground just like a bird landing on a limb.
