To be fair. That's pretty much what the Wright brothers did as well. They learned how an airplane works and also flew one that was fastened to the ground in strong winds. So before they made their actual first flight they already had "flight experience". Something not all aviation pioneers had back then.

I'm not sure where the notion that autogyros are inherently unsafe comes from. Back in the 20s and 30s many aviators flew them and regarded them as more safe than airplanes due to the fact they could autorotate and can take off and land in very short distances, and also capable of very slow flight, whereas an airplane would stall. Amelia Earhart flew one for years. She set at least one record in it, an altitude record of 18000 ft. If you expect them to fly like an airplane, then yes they probably are unsafe. It kind of looks like Peter is falling into that trap with all his initial crashes. I've only flown one in simulator but if I recall, they don't rotate at takeoff. At sufficient air speed they just lift off without changing attitude.

@@tmlf1239 Hi I fly gyros though not for a few years. The gyros safety record is undeserved the safety records of people trying to teach themselves and some appalling instructors resulted and still results in a terrible safety record. One of the issues is they are a very high wing loading machine meaning that when the rotax 582s became available we could have dual control machines unfortunately that same machine was available as a single seater. So the empty weight of that machine was probably 130kg. Now add two 90kg male pilots and you have a machine just able to fly. Take one out and you've lost about 1/3 the weight and it flies like a completely different machine. The stick sensitivity alone is massively different. Gyros have a few things that can bite you on the arse but much safer in others. For example no stall no spin. I've had 4 engine related emergencies two full on engine failures. Non event I'm a gyro but you can't fly them fast.

Of course this marked the end to the effective commercialization of the Autogyro. Despondent Pitcairn was found dead from a gunshot wound.

"once it's in the air it flies like an airplane" - From what I've read written by other gyrocopter pilots this is MOSTLY correct but not in one critical area - if you start stalling in an airplane and lose airspeed the correct answer is to pitch the nose down. In a gyrocopter, that'll get you killed very easily as it can send you tumbling ass-over-head very quickly. The autogyro aspect of a gyrocopter should be adequate to spin the blades back up again if you stall out simply by sacrificing some amount of altitude - but you *must* keep the airflow coming from the *underside* of the plane of motion of the blades or you're going to have a Very Bad Time™.

For when you go full scale: Gyrocopters have a very specific safety issue that fixed wings don't, despite the fact that they control the same. Don't ever unload the rotors, it's a deadly issue that can't be recovered from. Essentially, it's like letting go of a kite string. You cant fix it once its gone. It's called Power Push Over. Rule of thumb is dont allow yourself to get negative g's.

@thomassuit7450

2 жыл бұрын

You can see that happening in some of his model flight tests. You need to level off *gently* after climbing out. Ease off the power before pushing the stick forward. If you unload the rotor by letting wind blow in through the top, the wing quits flying and you fall like a rock. The other thing that is different is that if I recall correctly, control inputs are not held like with fixed wing aircraft. So like for a right bank you would move your stick right and return it to neutral, then to exit the turn you do the mirror image (stick left, then return to neutral) of what you just did to enter the turn. It's been decades since I was looking at these so I could be wrong on that one. Get formal training before trying to fly the real one.

Can add few more things: odd number of blades is generally recommended for RC gyrocopters, and you can make one from a RC copter body, where swashplate will handle uneven pitch for you, stock 3 servos will give you good control without real need for a yaw control on a tail, and stock main gear with some tinkering can be used for prespin (but you have to add a tail for stabilization anyway). Also mixes will help a lot with stall and rollovers related to burst of thrust.

It's not just the aerodynamics that doesn't scale well, it's the ratio of gyroscopic force to the mass of the vehicle. (i.e. your aircraft is so light, the gyroscopic force dominates at high rotor rpm). If you add a second rotor in contra-rotation, you will reduce the gyroscopic forces and have more stability. Optionally, you could add more mass to your aircraft.

I remember when I was reading up on autogyros that the most common way to kill yourself was called a Power Push(or Pitch) Over. Basically at the end of a climb, a pilot should reduce power FIRST, then pitch forward. This was especially a problem with models that didn't have a horizontal stabilizer, and a motor thrust line way above the pilot. The mistake would be to reduce pitch first with full power (Because, yeah, you want to go fast now that you're done climbing, right?). Doing that reduces the drag from the rotor, but not from the pilot/cockpit. The center of thrust ends up way above the center of drag, and the whole machine tumbles and is unrecoverable.

not quite right although this myth has been largely accepted by most in the gryoplane community. I used to fly bensen gyros years ago and am building a new one slowly now. I was trained in the gyroglider then two seat powered then lots of time in my own machine supervised doing strip runs. I never saw an accident at that club we were very well trained. When I went onto become a gyroglider instructor myself for 16 years off and on in that club and our own club in my state. no one ever smashed up a set of rotors under my instruction either. no stabiliser necessary. meanwhile our sport copying off the USA had decided to blame a lack of stabilisers so Australia mandated them. well all that meant was everyone who died died with a stabiliser. that continued at the same rate today. Next in UK a proper scientific analysis was carried out which concluded that speed was the most important factor and that stabilisers were of no help but c of g relative to thrust line was which is true. however machines like the dominator remove the 3 degrees of downturns which in the Bensens puts the thrust line through the cg and keep it flat but bring the mass up. So everyone continued to ignore good training and deaths continued. one guy visited our club and was boasting about his new machine and how fast it was. He claimed he was going to be getting up over 100knots the following weekend he had mabey 5 hour solo. Myself and about 5 others warned him he could inadvertently push the rotors negative trying this and should avoid flying that fast he cited the very large stabiliser like the one on peters machine and the high vs thrustline so wasn't worried. His gps when recovered showed he was doing 95knts when he bunted over the force on his body was so sudden his ripped his harness off and was flung out of the cockpit leaving his leg behind in the process. as you get faster and faster your disk angle become shallower and shallower. push it over and the airflow reverses and in about a second you will fly straight through the rotor and die. anyone tells you otherwise ask them to fly at 100mph straight over the airstrip and punch the stick full forward. if they do I'm convinced they'll kill themselves right in front of you. if they are not willing to try that experiment and actually don't tell them to do it you don't want to be even partly responsible. however I note many including many instructors are willing to make these statements often when trying to sell you a gyroplane. A quick google search of gyroplane fatalities will show you almost all have stabilisers, almost all have high CG to thrustline. the ONLY way to be safe in gyros like all aircraft is to spend the time to get excellent training. That includes you to Peter. don't I any way convince yourself you can safety teach yourself to fly these things. get proper instruction then spend many hours after your instruction in heavy dual machines under supervision doing ground runs.

If the stick is pushed too much forward, it will cause the entire retrieving blade to stall, and the rotor stops spinning very quickly.

Hey Peter, thanks for the video. I did my initial training as a helicopter maintenance engineer working on Seaking Helo’s. So, I am pretty much full bottle on the workings of fully articulated rotor heads. I’ve spent a lot of time in the left hand seat of different helicopters flying under instruction so at a pinch I could probably walk away from a landing if the pilot was incapacitated. I have a fixed wing PPL and own my own aeroplane but the lure of a gyroplane has been a long held dream! My question is - why don’t Gyro’s have 4 bladed rotor systems? In just about every KZread video you see of the cockpit view of the flight, the control column is always vibrating in sync with the rotation of the rotor. Surely a 3 or 4 bladed rotor head would make for a smoother ride. With the amount of theory of flight I’ve done over the years I should probably know the answer but I don’t! Is it just a cost thing or is it too hard to engineer for a gyro’ set up. (Both in real life an R/C applications) Cheers. SA

The advancing blade has more airspeed so lifts washing off some angle of attack the retreating descends increasing its angle. Result is equal lift around the disk. It also has the added benefit of equaling lift if you hit a thermal on one side or front first. In a fixed wing you often hit a thermal say on the left wing which tips the aircraft. In a gyro that blade lifts washing off some angle of attack the retreating blade drops so equal lift both sides and no bank or pitch change.

That effect he describes where the craft would try to pitch up then roll over. That is the torque I am talking about. Centripidal forces like trying to turn a spinning wheel in your hands ehich applies a felt force. The blades spinning are the same. If the craft is going to try to roll/turn on an axis, then other forces will apply. Craft trying to roll over due to lift differential, counter force is likely the noted flare. That is what I was addressing with the smarter every day video. And that is where it would be interesting to see if a dual blade setup countered the effect even if it was not ideal.

I think by having the 'gyro' style prop unrestrained it tilts back causing drag and lift but when you add the thrust vectoring rudder it increases the angle of attack exponentially but only on one blade which is why the crazy roll every time. The way you did it is different than I would but it's crazy you got it to fly :) I hope you build more of these love your work.

Oh maaaaan, I can't wait to see you fly the full size one. I've dreamed of owning 1 of these when I was a little kid, pretty much all the way up to adulthood. You are living my dream now.

Next up, cyclocopter? :)

love these things!

my friend Al Ball who I used to serve iced tea to in the cafe 126 owned a Hughes auto gyro, which day he was showing to none other than harrison ford. Al always demanded his iced tea to be served a particular way. We made friends after I asked him about his auto-gyro and he responded with admiration at the correct usage of the term. RIP Al.

that was really impressive, well done. At times you could here the blades chuggin' like a full scale, cool!

00:11 Autogyro. Fully pedantic. It would be cool to see one in tractor configuration, like those of the 30's.

Yea they make check out little wings autogyro.

build auto pilot in it

I made a nitro autogyro with an RC plane fuselage and tail feathers using 4-layer wood foam and Kevlar cloth and resin which was vacuum bag sealed for the blades. I made a jig to get the shape while the layers were drying kinda like making a skateboard deck. It worked really well once I had the tail feathers at the proper size. I'm really fascinated with Gyrocopters. Best of luck on the full-scale one. You will do great.

Saw the thumbnail and was like no way, he did a gyroopter?

Fun fact, you can sail a boat by the same principle if you put the rotor vertical;)

This explains a lot, I always found the way the gyrocopter behaved in 7 days to die (videogame) was very weird, this video makes it clear to me that it actually makes a lot of sense.

I have an RC gyro copter I got from Hobby King several years ago. It flies well, but like you said in your video, it takes a different skill set to learn to fly it.

I often find myself wishing you more frequently made content, Peter!

I actually used to work on these before I began working on helicopters. You can call them “Gyrocopters” or “Autogyros” but you cannot call them “Gyroplanes”. “Gyroplanes” are actually different from a “Gyrocopter/Autogyros”. I’ve worked on them for quite a while.

omg i have been obsessed with gyroplanes this month, great timing peter :)

Recognized it immediatly. Learned so much. Thanks for the upload!

Fantastic work, Peter! Well done!!! 😃 Stay safe there with your family! 🖖😊

Love how you don’t get disappointed or discouraged

This is re-living multiple KSP engineering nightmares lol. Gyrocopters do like 80% of these things in Kerbal as well. Especially if you build them without mods or DLC.

I am used to watching you crash a few things at the beginning of one of your experimental builds, but wow. I’m scared to find out how many parts you had to make over and over. There were so many smashey smashey times. I’m glad you are persistent. ^.^

Totally cool!!! I remember the Benson gyrocopters that came in when I was a young teenager. I dreamed of taking one of those on a cross-country trip.

gyrocopters are awesome! my grandfather has been hand building and flying them for over 40years 👍 very cool machines

You should look up the Rotordyne, it's a gyrocopter that was being made for passanger service. It had at least 1 prototype that flew, but unfortunately didn't go into production.

Excellent , what a coincidence,I purchase a Cierva C30 Model about 10 yrs ago are about to finish it this month, thank you for all the heads up

Damn, haven't watched your channel in "a while" but the production value is really taking off! Keep it up 🙏🏻

If you want more stability in your gyrocopter do the following in order of preference: 1) Lower the thrust line and raise the centre of gravity. The CG needs to be higher than the thrust line, so that thrust will cause a pitch up moment. A low CG will make the aircraft dangerously unstable. 2) Put a big horizontal stabiliser on it on a long tail 3) Use a tractor configuration. Nice video

Super cool man, really like that you made something that most people probably never have heard of. Thank you for the info, will build one of these babies myself.

The second I found out u uploaded my day just got 1000x better

Amazing stuff Peter! Glad it's not just another quadcopter)

The physics of autorotation is just brain boggling. I studied it as a helicopter technician. Understanding it is what saves you in a helicopter when your engine quits and you have to do a dead stick landing.

Always superb to get a notification on a new Peter Stripol vid! Long time fan Man keep it coming! Thank you.

Okay this is awesome because you added the history in the beginning. Super interesting!

I built a GyroBee decades ago (Lazybee, but with a rotor on top instead of fixed wings) thinking the tractor configuration (prop in front) would be more stable than the pusher configuration (prop on the rear). This was my first and last (so far) RC aircraft build, so the fact that I wrecked it was probably due more to my inexperience than anything else. It did have three blades and that flexible triangle thingie instead of a proper teeter totter type rotor mechanism, so your video makes a lot of sense to me.

You must feel proud massive achievement well done 👏

Holy cow your editing skills are really good now! Looks really nice compared to older videos! . good luck!

I in Bryn Athyn PA and you can still see faint remnants of the Pitcairn factories where the planes where constructed. You can also make out the fields where Amelia Earhart, one of the Wright brothers, and Lindbergh once flew.

Always a wonderful day whenever you release a new video.🙏👌

Peter you are the perfect mixture of madman and scientists. Stay safe brother!

I had to build one of these for a Spanish assignment once. Went as well as it sounds

I never knew how hard these were to get off the ground! Really cool video!

I can't wait for the full-scale build series! And I really want your opinion on sketchy fixed-wing vs sketchy auto-gyro. Just don't do the one thing that you are never supposed to do in a gyro or you will bunt-it out of the sky. :-o

I am so happy to see you come back to the gyrocopter!

ITS THE COUNT! IN HIS AUTO - GYRO!

Dang, this looks awesome! Have you been using any light-weight filament for the rotor blades (such as ColorFabb LW-PLA, which "foams" the PLA as it's extruded) or just straight PLA/PETG/ABS?

I love helicopters! And damn it if Gyro's arent even cooler... we were gonna get a really cool one for MSFS 2020, a very fancy one, but it seems to been delayed, so sad! Anyway, this was super cool, watching the crashes hurts! Cant wait for more of this!! :)

I was just beginning to wonder if they were possible in MSFS! So glad someone is already working on one.

So glad you finally did it!

Cant wait for the files! Super super cool build. I have about a 50% success rate on getting rc autogyros to last more than a minute in the air. I am very impressed with the way that model flies. Especially with the wobble head!!

Peter, first of all great job! The only problem for me was understanding how the gyro worked. You didn't explain what was going on during flight. You said autorotation at one point, which clued me in on things, but other than that, I felt confused as to how the gyro was unique. It's obvious that the lift rotors aren't powered once you know that fact, but I didn't know that. I assumed they were powered for most of the video. Other than that, thanks so much for the video and I hope you get all the love you deserve on youtube.

damn sripol flexing at 3:00 what a nice surprise not spoiling it in the title

"He's a bag of bones". Oh Peter, you're killin' me. You should take your act on the road.

That was magnificent, in all ways. Thank you - and please take care in that full size model...

Dear Peter, great work. Very intrigued by how gyros / autorotation works. So glad to hear you say that the pitch is 1.5deg negative. Have seen and heard quite a few folks totally convinced that it is 1.5deg positive. I think I have the answer on what the main driving force is to give autorotation in forward flight. No one is considering the full rotation. Think of it as three quarters. The rear quarter the segment is towards the horizontal and in disturbed air, so not doing much. Now the forward facing segment has a good upward flow across its whole length, and the negative incidence causes it to rotate. This is where the major force comes from. The leading side segment gives drag, though this is somewhat balanced by the push from the trailing segment, though still an overall slight drag against rotation, but far less than the positive rotation from the front segment.

Can't wait to see the final version of the plane-o-copter
