It's known as a jump takeoff to do this, gyrocopters require pre-rotator that uses a trasmission clutch, this allows gyrocopters to do a near vertical takeoff. Some gyrocopters have a collective pitch to reduce blade pitch before driving the rotor (Collective pitch controls are not usually fitted to gyrocopters) While technically not a true gyro the rotor blades can still be turned by autorotation when the clutch is disconnected. Instead of pre-rotator some gyrocopters have hydrogen peroxide rockets on the tips of the rotor blades to allow the gyrocopter to takeoff and land vertically. Pre-rotator and tipjets are only used during takeoff and landing allowing gyrocopter to takeoff and land in short distance or without the need of a runway at all.
Mr. DeGraw has 2 Gyrhinos. I believe the other one is flown by his wife. Both Gyrhinos were flying around my house this morning South of Jackson, MI. Really cool stuff. I wish they would drop in to my airstrip sometime. Nothing fake about it.
This is a custom gyro and it does have a collective that changes the pitch of the rotorblades for the jump-takeoff. The blades then return to a fixed pitch for normal flight.
For all those interested in the history of Jump Takeoff, go see the original 1930's example here: ua-cam.com/video/iAENPTmjBCg/v-deo.html . As some have said, it's a hybrid form: the rotor is spun up to high revs initially on engine power, and with a 'snap' action the power is then removed just as the pitch is pulled positive by a version of the cyclic as used in a chopper. That means for a few seconds the rotor gives helicopter-style lift - just for the jump - and as the craft makes forward speed the pilot then drops the collective and reverts to autorotation (where the upward airflow through the rotor disc keeps it turning). Because the rotor disc is tilted back the disc has a net angle of attack and so as the aircraft flies forward, the lift continues without futher motor power to the rotor. Dick seemingly has made a modern version of that 'WhirlWing' from the 30's. There are one or two other craft that can do it, most famously perhaps the marvellous but sadly now long gone, Air & Space 18A machine.
@skyboy1956 Have you inspected this aircraft in-person? I have. It has a collective. Dick pulls the collective to change the pitch for the jump takeoff and then returns it to the flying pitch. If all it takes is facing into the wind to perform a jump takeoff we'd all be doing them.
Cool! I've been reading up on Autogyros. The jump happens when the power is removed from the rotor and the blades change pitch automatically. This effect was discovered by Juan de la Cierva in about 1936. He was the front runner in developing these brilliant little craft. 5/5
@sotakeheart1 No. This is a custom-built gyro. It's kind-of a cross between a helicopter and a gyro. After the jump takeoff it flies like a gyro. A normal gyro cannot spin up the blades fast enough to perform a jump takeoff like this.
@tchick it may be custom built, and jump take off may be fairly unusual, but it is just a gyrocopter. A hybrid rotorcraft either has wings or a rotor that is powered during flight. This has neither.
@liqu1dcham3leon This is a custom hybrid aircraft. He has collective pitch like a helicopter to achieve the jump and then transitions into autorotation flight (like a normal gyro flies) after the jump.
@killobot9 OK Mr Smarty pants, If you're referring to gliding without a wing an f15 did it once. That was one of those one-in-a -million occurrences and they weren't gliding. They were using a lot of power. Let's see them do it on a regular basis. There have been several recent incidents where small planes have lost their wings in flight and they were not able to glide. What kind of aircraft do you fly?
No. It will jump whithout a headwind. Dick built another gyro like this for his wife this past year. Someone posted a video of them jumping both gyros at the Mentone, IN flyin.
the engine isnt engaged to the rotors when he leaves the ground. he us's the engine to spin up the top rotor to high speeds, then he disengages it from the engine and pitches the blades to grab air.
This is a great example of needing more training before flying a gyrocopter. First 100 hours are when you get confident and crash. He was lucky to still be here
@tchick ...If you look carefully, you'll note the rotor never "cones" prior to liftoff to suggest it is pulling collective pitch and providing lift. Also rotor torque, and the rearward tilt of the rotor would cause issues. The Gyrhino is a true autogyro, the rotor provides lift by air flowing up and through the rotor, not vice-versa like a helicopter. I believe in this video, Mr. DeGraw is facing into the wind which contributes to the spectactular zero roll takeoff run.
I guessing he had an engine to move the propeller, then turned it off, therefore removing the torque, then angle the propeller up to pruduce the lift? Am i right?
Not really. He just changes the pitch in the blades to do the jump takeoff. After that the blades return to a fixed pitch for normal flight. The benefits of autogiro flight compared to helocopter flight is less pilot workload. Most gyros will fly hands off the controls. Most Helos don't.
Ah, so is this type of mechanism not available generally? I see a LFINO machine on here with it.. Yes, I guess it would be better if the pilot initiates the jump rather than it happening automatically, as on Cierva's earlier ones.
On a gyrocopter, the rotor is powered only during the rotor launching phase.Here it's a heawy rotor, drive at high speed, the jump take of is take at free wheel rotor, on the inertia from the rotor...A single rotor helicopter cannot fly without anti torque prop (or a "NOTAR"), only exception was the french helicopter Djinn who use a jet powered rotor...
@@leneanderthalien It is not a true gyrocopter if it can power the main rotor at any stage, it is some kind of hybrid. Btw there are any number of helicopters that do not require a tail rotor including more tip drives than you mentioned. But Synchropters, twin rotors and Co Axials all operate sans a tail rotor.
A normal autogyro will not do a jump takeoff like this. This Autogyro has a rotor head similar to a helicopter. The pilot changes the pitch of the rotorblades to create the jump.
Most gyros do not have a collective. It adds a lot more complexity to the rotor head, etc. This gyro is a custom designed and built gyro. It was a one-of-a kind gyro until he built a second one for his wife to fly. He has a third gyro with a collective that I know of, maybe more that I'm not aware of.
tchick (2 months ago) Because I started video taping other aircraft and didn't see him land. Sorry. Aircraft can do that to your brain. My high power rocket club was awed by a fully restored P51 taxiing past us. It was already down the runway and airborne before ANY of us realized that NONE of us had enough presence of mind to take pictures(most of us had cameras at the ready)
The rotor is powered on the ground while the torque is absorbed by the ground Wheels and then the power is removed from the rotor after it's spun up really fast like a flywheel and then they change the pitch. Because the helicopter engine is not supplying torque it doesn't cause any twisting motion but the blades flywheel start slowing down a lot with resistance so you only have a couple seconds of take off power before you start coming back down.
@importsc41886 I think you have use a "kind" word :-) But since I don't know who is the designer (amateur,company, etc...) I think it is however...interesting.
Read my comment again. When his engine DOESNT disengage. You do understand what doesnt means i hope. I fly autogyros too and i know peferctly well how they work.

What makes you think the blades change pitch automatically? This must be done manually with a collective control.
@@Make_Boxing_Great_Again Who knows mate. 15 years after my comment I cba to research it all again. 😁
Wow. This one such a powerful engine. Nice!
Yes. This is a hybrid aircraft. The collective is used for takeoff only and then it flies like a gyro in-flight.
This thing is marvelous
fantastic, quick start!
@sotakeheart1 No. This is a custom-built gyro. It's kind-of a cross between a helicopter and a gyro. After the jump takeoff it flies like a gyro. A normal gyro cannot spin up the blades fast enough to perform a jump takeoff like this.
@Puronicth It does not use a separate engine for the prerotator. The prerotator is supplied power by the one engine.
great video
@tchick it may be custom built, and jump take off may be fairly unusual, but it is just a gyrocopter. A hybrid rotorcraft either has wings or a rotor that is powered during flight. This has neither.
É de dar inveja a muitos helicóptero por aí. Parabéns pela proeza.

AWESOME! NO runway needed!
Wow! Crazy horse, or...crazy fly!
Thats nifty, I want one
and the world is beautiful from that

He’s been flying gyros since the 60’s. He’s built 2 or 3 different jump takeoff machines and designed and built a homemade helicopter.
@tchick - I don't even trust birds because they can't glide if their wings fall off.

cool, blue skies.
if its vertical thrust rotor is powered, then is an actual helicopter, isn't it?
YES !!!! your right a Gyrocopter has NO engine or power on rotor blades
On a gyrocopter, the rotor is powered only during the rotor launching phase.Here it's a heawy rotor, drive at high speed, the jump take of is take at free wheel rotor, on the inertia from the rotor...A single rotor helicopter cannot fly without anti torque prop (or a "NOTAR"), only exception was the french helicopter Djinn who use a jet powered rotor...
It looks like a chopper to me

Btw there are any number of helicopters that do not require a tail rotor including more tip drives than you mentioned. But Synchropters, twin rotors and Co Axials all operate sans a tail rotor.
impressive but why not include the landing also?
@tchick Because Gyros can glide when the rotor falls off yeah?.
Are these expensive to maintain and how safe can these be?
there must be a powerful engine, this gyro jumps like a helicopter
A normal autogyro will not do a jump takeoff like this. This Autogyro has a rotor head similar to a helicopter. The pilot changes the pitch of the rotorblades to create the jump.
Can it do a normal takeoff
Hi. I'm new to this. Is that a "prerotator" he uses to get the main disk up? Is that a separate motor for that?
How is that possible?
what is different about this one that it can take off with no ground roll?
Is it possible to know where to find more info on this prototype thanks
Do all Gryo's have a collective? If not, how much complexity does it add to a gyro to add a collective in order to achieve this? Very cool!
Most gyros do not have a collective. It adds a lot more complexity to the rotor head, etc. This gyro is a custom designed and built gyro. It was a one-of-a kind gyro until he built a second one for his wife to fly. He has a third gyro with a collective that I know of, maybe more that I'm not aware of.
and if the rotor blades comes of? what then?
@gewizz2 its not true :] heli can landing save with no working engine ...
How much?
do want!!!
@tchick An F-15 can, apparently.
tchick (2 months ago)
Because I started video taping other aircraft and didn't see him land. Sorry.

so how do we buy one????
WHAT? how the hell did that happen? is the rotor powered or free-spinning?
The rotor is powered on the ground while the torque is absorbed by the ground Wheels and then the power is removed from the rotor after it's spun up really fast like a flywheel and then they change the pitch. Because the helicopter engine is not supplying torque it doesn't cause any twisting motion but the blades flywheel start slowing down a lot with resistance so you only have a couple seconds of take off power before you start coming back down.
Find a gyro flyin and go for a ride. Where do you live?
you can find his joke behind you, it seems to have GONE RIGHT OVER YOUR HEAD
It's time to meet Jesus.
I don't get how gyro copters work.
I expect you don't trust parachutes because the chute can fall off too!!!? Right? Haha!
@importsc41886 I think you have use a "kind" word :-)
But since I don't know who is the designer (amateur,company, etc...) I think it is however...interesting.
I don't fly high enough to use a parachute.
Read my comment again. When his engine DOESNT disengage. You do understand what doesnt means i hope. I fly autogyros too and i know peferctly well how they work.
Yes it must be disconected or it turns into a helicopter with no tailrotor control and that is bad!!!
The results will be worth seeing when he does a jump start and his engine doesnt disengage from the top rotors!!!
Impressionante gostaria de ter mais informações sobre o sistema que aciona o rotor principal para conseguir este efeito!
not true. it will auto rotate all the way down
@importsc41886
A Dragonfly is ugly compared to a Peregrin Falcon, but both are ultra sucessful. ;-)

I don't trust planes because they can't glide if a wing falls off.
collective or what?
i dont trust helicopters bcoz they dont glide if a blade falls off
but cool
@tchick What if your rotorcraft loses its wings?
Сколько стоит
