Roton The Rotary Rocket - Half Rocket - Half Helicopter

[@Hexum064]

I helped (in some small part) build the Roton. Good times and a fun little company. Not great with money management. But the test take-offs were amazing to watch and really inspiring. P.S. I think Scott did a great job representing it here. No real out-of-context facts or misleading comments. Thanks Scott!

He really did a fine job. Glad he focused on what it was meant to be. And yes, Watching it buzz down the runway on rotor was cool indeed.

Back in 1999, I made a 3D online model and sent it to them, which they published on their website. This earned an invitation to the rollout of the ATV, which was brilliant. Everyone was very friendly and accessible, and I ended up having lunch with Mrs. Binnie (completely at random) and had a sit in the cockpit. Marvellous concept, pity it didn't quite get to orbit.

[@hagerty1952]

I was there for the rollout of the Roton ATV in 1999. I had been visiting the offices of RR (which were in Redwood City up in the Bay Area) to interview the designers and marketing people for "Spaceship Handbook" so I got an invitation. The Roton was one of several completely reusable launch systems being developed at the time that I was including in the last chapter. The Roton was, in fact, the last entry of the last chapter, closing out the whole century that had opened with Tsiolkovsky. BTW, Scott, the propellant tanks surrounded the payload/cockpit section. The fuel (kerosene) was a flat ovide tank between the engines and the payload while the LOX tank was a narrow conical frustum starting above the cockpit, all the way up to the rotors.

Whoa Scott! I actually went out to Mojave Airport a few years back and saw the Roton Rotary Rocket prototype featured in your video as well as the SpaceShip One in its little display building. Also on the grounds of the airport is Scaled Composites where Rutan built his various designs including SpaceShip Two that is supposed to start conducting commercial operations for tourist astronauts. Thanks for the great video of this cocamamy rocket with the rotor blades.

[@AngelLestat2]

I also love this concept, of course 1 stage to orbit was the biggest drawback, but as a second stage would have been amazing. Autorotation is something very safe that any helicopter can do and you dont need extra power to land soft at all, only if you are still very far from the landing pad or the weather is too bad an external power source could increase safety.

[@mongoose404]

Hello Scott! I think you should see a movie from Soviet Union called "Kin dza dza". Aliens from another planet have vehicles looking almost the same as Roton. You may find a version with English subtitles in the net. Promise me to not fall asleep while watching this move ;-)

[@beachcomberfilms8615]

I actually stumbled on this yesterday at Mojave and was curious about it as I’d never heard about it. Thanks Scott for the video.

[@russschnapp4510]

Actually, Classic Rotors (Ramona, CA) was supposed to have taken the Roton to its museum. As I heard the story, they raised money and paid expenses for a US Army helicopter to transport it from Mojave to Ramona. Unfortunately, the Army crew miscalculated the required length of the lift cable (Classic Rotors' guys said they told them they'd need something like 200', but the Army guys decided to use less than half that). When they tried to do the transport, things did not go well soon after lifting off. Payload and helicopter fought each other for control. As Classic Rotors tells the story, the Army pilot sweated bullets just getting the thing back on the ground in one piece at Mojave. They then told Classic Rotors that they were done trying to transport the Roton. If you visit the CR museum in Ramona (and I strongly recommend it), you will however find the actual rotor mechanism from the Roton, and I think they also have the blades stored away.

[@rocketkenOG]

Pretty good video! I had quite a lot to do with this project; my first job in the rocket business. Much of the ridicule I see in the comments appears to be from a lack of vision. Yes, SSTO is hard, but has been possible from since the early model of Atlas; the delivered non-structure payload is indeed small. Reusable SSTO is harder still, but with attention to very lightweight structure and efficient engines, is also possible; the "Holy Grail" of reusable space launch operations. The spinning rocket engine base would have generated high propellant pressures for high-chamber-pressure rocket motors, which are key for good lift-off performance. Much of the charm of the spinning was to eliminate the need for turbopumps. Counter-rotating rings of the base motors probably would have eventually been needed to deal with the gyroscopic forces. We certainly showed that the "centrifugal pumping" worked with the rotor tip rockets. The structure was large, but able to be very light due to the axisymmetric cone shape and carbon fiber construction. The rotor blade landing system was analyzed to weigh what a parachute system would have weighed for a sea landing, but would have allowed landing with style at the airport. Lastly, $30 million was a comparatively lightweight investment as a start to do this sort of thing..

The 96 combustion chambers around the aerospike/heat shield were fed with a centrifugal pump the width of the base. The entire engine was rotary! On the yes that's clever end of the spectrum, at least the heavy end always pointed down (as opposed to the Venture Star).

2:14 Американцы никогда не узнают тайну гравицапы и не смогут построить настоящий ПЕПЕЛАЦ In 1986, the Soviet Union was the sci-fi film Kin-dza-dza! And Roton is very similar to the main vehicle of the main characters: Pepelats in this film. After the film was released, the American colleague called to the director (Georgiy Daneliya) with a proposal to make special effects for his film. The American said that he was impressed with how Pepelats was flying. Danelia joked to him: “There are no special effects there. The military gave us "gravitsapa". We put it on the scenery, and spaceship had flown. You should call to the Russian military. This is their design. What if I suddenly will tell you a secret information. I will be considered as a spy!". And American director for real did it! Then the author of the film was called from the Ministry of Defense of the USSR and was shouted: “Are you fooling around?”

[@thomascharlton8545]

Scott, There’s more to the story. Gary Hudson’s original concept was to have rotor blades attached to an annular slip-ring around the base of the vehicle. The idea was to use centrifugal force as a means to pump fuel/oxidizer out to rocket engines at the rotor tips.

Seems like this could work as the upper stage/return vehicle. Not lift off on it's own to orbit. That should be obvious. Back in the end of the last century I was doing aeronautical engineering in college in the Netherlands, and had a friend in Redwood City. They had their head office there on the bay. I did contemplate if I could do my graduation project there. But life turned onto a different road then for me. And soon there after also for the company I guess.

[@nathanaelvetters2684]

That's a good point. This could be used in a system much like Starship, where a reusable first stage gives this a kick, and then it goes on to orbit on its own power, bit needing to reserve any fuel.

[@codetech5598]

As I remember, the original Roton had the engines only on the tip of the rotors, not under the vehicle. There were no turbo pumps but the fuel was flung out to the engines on the tips of the blades by centrifugal force. As the rocket corkscrewed its way up through the atmosphere, and as the atmosphere became thinner, the pitch of the blades would increase until the engines were pointed almost straight down.

[@samuelpaik]

My memory (which could well be faulty) was of watching a live streamed broadcast of the final test flight. The original engine had the rocket motors mounted on a rotating disk, the fuel and oxidizer would come down in the center of the disk and then out to the individual motors, the rotation of the disk would act as a pressurizing pump, instead of using a turbopump. The rotation would be powered by having the motors canted slightly along the circumference of the disk, not inwards. Essentially, the rotating disk was a centrifugal pump.

For manned missions it would have a small winged glider as an upper stage, which would have abort rockets to escape the launch vehicle in an emergency: en.wikipedia.org/wiki/Chrysler_SERV

Agreed. Gyroplane flight is a criminally underused and underappreciated system but that thing looks like a single stage to 10km up vehicle, not a single stage to orbit.

My most vivid memory of Brian was a flight test report I wrote where I said "the pitch response to the step input was well-damped." He wrote on the report that "terms like 'well-damped' were not appropriate for a flight test report". When I asked him how I should phrase it, he said that I should have calculated the damping ratio. I was just a contractor, so I replied "yes sir" and did as I was asked. Of course, I had no idea what the damping ratio was designed to be for this aircraft, so to me, sticking the number in there was the same as simply saying "well-damped" and showing the graph, but whatever - he was the boss!

[@lukeshoff3983]

Why doesn't the fuselage rotate? All helicopters I have seen have at least 2 sets of blades to counter out the net torque.

[@LoneStarr1979]

because the rotor was driven by small nozzles at the tip of the blades. This way, the rotor itself generated the torque that is needed to drive the rotor. Thus, no torque on the fuselage. (respectively only a tiny ammount generated by the bearing of the rotor)

[@TheEvilmooseofdoom]

Yes it did, they had to use small thrusters to provide counter rotational force.

[@russschnapp4510]

The only rotational force would have been from downwash and/or rotor bearing friction, so there probably wasn't a lot of rotational counter-thrust needed.

@@russschnapp4510 The spin, regardless of it's source, always produces a counter spin.

[@russschnapp4510]

@@TheEvilmooseofdoom Uh, no. I don't think that's the physics of the situation. If you drive a shaft, you will get counter-torque. If you use reaction jets to spin the blades, there's no torque whatsoever on the shaft, which is only used to suspend the rotors. Likewise, if airflow is used to spin the blades, there's no countertorque. This is why there is no tail rotor on an autogyro.

Consider a design for landers under a ton wet that have motors below the CG so a bitch to land, moving them above the load solves it. So, the exhaust of a toroidal sheath motor aimed 45° over a nacelle and reduced to 340kts adds lift to remaining thrust, 1st pass has 2x hovering total force up. Then, hovercraft ascend most efficiently sideways not straight up, so, to get to orbit they spiral out. Then, this works in a vacuum and appears to save enough fuel to allow a takeoff for rendezvous & resupply, an alluring concept Have a paper for IAC going this fall as a design analysis of the idea, cheers!
