Ikarus electric "rocket" - Thrust-vectored flying ducted fan

[@tesla500]

Design info, CAD files, firmware, etc. is now up at omeganaught.com/2018/08/ikarus-electric-rocket/

[@deepmaze1]

For better stability performance, please add counter fins right after the impeller. They have to be counter directed against the rotating fan

[@tesla500]

The EDF already has fins to straighten the airflow after the fan

[@microtrigger]

[@justinsalazar4952]

That is really creepy. You should get to know someone before you love them.

[@taofledermaus]

There is no stopping you when you sent your mind to something! I would have thought the body of the craft would have to spin in the opposite direction of the fan from the torque. That blows my mind!

[@ColinJWiens]

Yeah I wonder how much power he loses by using the vanes to counteract the torque

[@drasiritzbir]

Well it does, but is counteracted by directed airflow with an axial component. You can see the craft yerk around the axis when the torque changes due to changed RPM of the fan.

[@tesla500]

Thanks! There are static vanes in the duct that straighten the airflow out, so there's no torque produced due to the airflow or fan spinning. The inertia of the fan does cause torque when spooling up or down, which the thrust vectoring vanes compensate for quite well as long as there's power applied. At low throttle, it can spin around quite a lot, but if you punch it above about half throttle, it stays in position quite well.

[@Hamza-or7jm]

Are the batteries causing it to lose balance? Will equal weight distribution sort out your take off issues?

I still remember the time when I built a plane with nicad cells and a brushed motor and it was just barely able to climb. Brushless motors and lithium batteries are quite something, combined with the electronics to keep them from plowing straight into the ground. The design challenges are very different now, but certainly no easier.

[@coriscotupi]

+stefantrethan I still have an electric powered glider by Kyosho that I bought about a quarter of a century ago. It was powered by a massive, brushed motor and a 10-pack Ni-Cd battery that added a ton to the sailplane. It barely climbed to altitude, then sank like a brick, and then did one more climb and that was it. Fast-forward to the 21st century, I replaced the motor with a much more powerful brushless one and a much lighter and more powerful LiPo battery. The glider now reaches altitude in about 30 seconds, easily glides tens of minutes at a time, can climb to altitude dozens of times in a single charge. I can literally get a whole flying day out of one single battery charge. Electric powered gliders of the 90s were ahead of their time! It is only now that even 25 year old designs reached their full potential.

Really cool project. Seems like landing it is one of the challenges at this point. Seems top heavy, but also the thrust is causing a turbulent ground effect. In the redesign of the frame you might consider having longer landing gear support the frame from the top for a wider, more stable landing surface. The legs could also be usefully designed as strakes for flight stability if you get into horizontal high speed flight. Hope to see more on this project!

[@dr.davidbannerf.e.s.6217]

Been studying this method of making a drone for a while. I have come across a new idea that makes it extremely level and upright without having to throttle the propeller up, or thrust vectoring to keep it level and upright. This requires installing a small but powerful motor to spin up a flywheel. You can put the flywheel and motor in a housing if you like, it doesn't need to push air or anything, just a ring spinning very fast. Using the gyro sensor steering assist off of rc drift cars and new rc trucks, you can allow the steering assist sensor to control the throttle speed on the flywheel motor. Both the motor and the gyro sensor can be set to automatic, whereas the flywheel is spun up to a certain speed, and then the gyro sensor can speed the motor up from there on its own. Adding this flywheel and steering assist sensor system to your drone, will make it extremely upright and level with force...because the flywheel can be spun up to a very high speed first...and then even faster when anything tries to tilt it over. Now that the upright and level part is taken care of seperately and automatically....You can simplify the flight controls for your drone, since they are no longer needed to keep it stable and upright. Also, this design automatically fights to level itself out if you walk up to it and push on it while its in the air, because the flywheel is immediately spun up faster. And you dont have to spin the propeller faster for that to happen...

[@piranha031091]

That is _really_ cool! Stupid question : if you gave it a pair of wings, could you make it take off vertically, and transition to horizontal flight? (and vice-versa)

[@WallHaxxx]

Dude, you need to cool your fucking jets. (or ducted fans in this case). There are considerable differences between the design of this drone and the T-Hawk (which you refused to even name as the infringed design yourself). The control surfaces are completely different (and innovative) as well as the internal ducting. And you seem to completely ignore his work modifying the software (which also has NO connection to your beloved military craft). The fact is that ducted, single rotor, thrust vectored, VTOL aircraft have been developed since at least the 1950s. See: the Hiller 1031-A-1 and the Willams X-Jet and WASP. airandspace.si.edu/collection-objects/hiller-model-1031-1-flying-platform hyperboreanvibrations.blogspot.com/2011/03/williams-international-x-jet-and-other.html You really don't seem to understand how IP and patents work. This man has done a lot of hard work to make something that functions and you are shitting all over his contribution to aerospace engineering. He didn't "steal" anything. He designed his ducting himself and the geometry of the fins and cutouts alone would be enough to patent his design, but he chose to share it with everyone instead. You need to step off your high-horse and show some respect for a guy that put a lot of love and effort into something so that we could all enjoy it and keep building on the idea.

Old video, I know, but if you had approached the controls like a "normal" rc helicopter instead of a mulitrotor it actually has de same type of gyroscopic effect on cyclic controls with 90 degrees of change and the need of compensating the yaw with the tail rotor. Having a flightcontroller used for flybar less rc helis might have been another way forward although you would have to mix in the tail rotor correction (yaw) in the vane controls.

I am working on a very similar project for my capstone project. I would suggest looking into adding stationary blades at the outlet of the duct to counteract the torque effect. Honeywell built a drone similar to this and that is their method of counteracting most of the torque effect so the outlet veins don't have to stabilize as much. It should put less stress on your outlet veins and make stability easier in theory.

Well yeah. The turbine is a gyroscope so if you move it along the y axis it's gonna begin to precess. So any movement in the plane of the turbine will need to be compensated by directing thrust in a orthogonal axis. The amount of compensation will depend on turbine speed as well which affects precession.

[@JTCF]

Factorio drones confirmed.

[@mihailazar2487]

OMG this is so inspiring ... like ... this just shows just how wonerful an engineer's mind is ...

Like ... this is not about persistance ... it's about how you see the world work ... we both know the world isn't perfect and it will never be, and if you see some of that world "imperfection" go directly against whatever physical device you're trying to build ... I would give up much faster I would have NO WAY THOUGHT YOU COULD STABILISE THAT THING WITH ANYTHING SHORT OF MACHINE LEARNING I woulcn't have thought that just applying a simple correction to the code that you get out by using the gyroscopic precession equasions would work, because turbulence and inertial instability and positive feedback loops and angular momentum in a closed system etc, etc JUST SEEING you tweak that one line of code, doing the exact correction the theoretical model tells you and achieving the stability sen at 16:07 SEEMED LIKE MAGIC TO ME like, idk how to describe this but ...

[@atomicskull6405]

He was actually wrong about something though, the phase delay of helicopter control inputs aren't gyroscopic precession it is an aerodynamic effect caused by blade being unable to exert pitch and roll on the airframe instantly the same as moving the elevators and ailerons on an airplane can't instantly pitch or roll the aircraft (a helicopter rotor is literally a rotating wing) The phase delay is (usually) close to 90 degrees, but not exactly 90 degrees and in some designs it's quite a bit off like with the Robinson R22 which has a phase delay of 70 degrees or the Sikorsky prototype I read about that had a phase delay of almost 100 degrees. (basically the lighter and stiffer the rotor the less delay and the heavier or more flexible the rotor the greater the delay). Gyroscopic presession is always EXACTLY 90 degrees so for phase delay to not be exactly 90 degrees in helicopters disproves the presession myth right off the bat. (helicopter rotors rotate too slowly and and don't have enough mass for gyroscopic presession to have a significant effect)

Great video. This is a familiar school soccer field that I think our kids played at when they were younger. I can’t seem to remember where this is but it looks exactly like a school soccer field somewhere in the Lower Mainland.

[@albertlopez1143]

Waterproof it and it works submerged under water...

[@KOKERzeroZEROseven]

it's manhack from half-life 2 ))

[@Kahimatsu_the_Pseudoscientist]

Yes Man lol

[@flanbro3530]

It's a factorio drone

[@zusurs]

Great video, as always! Just wanted to point out that yotube’s compression algorithm sh*t it’s pants during the intro of this video...

[@TheExplosiveGuy]

I love this thing! It's so swooshy and heavy looking, looks really fun to fly. And I love Kapton tape, I use the stuff all the time for strapping battering and components down too, it's so light and strong and the adhesive is badass, it's awesome stuff.

[@TelekineticFool]

I love the video, great capture of the new product development process. I like the idea of this for manned electric flight much better than standard quadcopter due to redundancy. If you had four vectored ducted fans such as this but had a control system that could compensate for the loss of one or two of them without a significant loss in control, that makes the flying car that much more achievable.

[@kevinbarker2082]

Go open source. Give it a shell. Kick starter it. This is awesome.

[@DieselRamcharger]

he didn't design it, he ripped it off.

[@jnevercast]

Open Hardware and Open source flight controller is hardly "Ripping it off". He had to do a lot of work to get it to fly, work that he implemented himself and wasn't copied. This is an original implementation of adapted works.

[@partickstar1135]

been done hundreds of times before..

[@jnevercast]

@@partickstar1135 if you're saying vectored engines are not a new design, and over coming gyroscopic procession and torque is not a new problem, I agree with you. Tesla500 didn't claim this idea as his own invention but this implementation of it is his own. Watching the video entirely makes that quite obvious.

[@gabest4]

It is too round on the top, it needs to be pointy.

[@kentvandervelden]

Off topic, but one of the few things I remember from an intro to aerodynamics class is why the US ICBMs worked and USSRs did not had to do with pointy vs. not resulted in different heat dispersion. I always thought that was counter-intuitive and cool.

[@volvo09]

I like the goofiness of it!

[@JPRucks]

Rounded shapes are usually more aerodynamic below transonic/subsonic speeds.

[@JPRucks]

Transonic/supersonic*

[@Ryrzard]

I thought this was The Dictator reference

[@boogerking7411]

How about lowering the center of gravity

[@tesla500]

That will make in-flight stability worse. The shorter the distance between the CG and the thrust vectoring vanes, the less of an effect the vanes will have.

[@manishiyer23]

Thank you 👌. It's a joy to see. Including the amazing clarity of description and honest earnest explanation ❤️

[@Jockl51]

Wow. Awesome stuff and it's great to see your thoughtprocess in making this!

[@infectiousfile984]

You can make the launch pad with pvc pipe....:-) :-):-)

[@visibleconfusion9894]

In the beginning the Fan sounds like a Emergency Siren

[@LiakatHossain]

When you get 1M subscriber on no video we will add music with it

[@Kris_at_WhiteOaksFarm]

The counter rotating fan idea reminds me of the Novel 'Butcher Bird' by Dean Ing. Love your research and development. What a fascinating little machine!

[@manishiyer23]

The little is a perfect discription. What an amazing swarm these would make. Pixels in the sky

[@Triple_J.1]

That's a really creative way to use an EDF. Love it!

[@Paddy.121]

Factorio logistic bots.. anyone?!

[@MrVolodus]

Yes! That's why I clicked! :D

[@manioresnik556]

YES !!!!

[@ozricm]

Factorio anyone?

[@rafipatra9542]

tutoriall

[@GeorgeTsiros]

they usually launch these things from a point where the ground is far enough lower, like from a pedestal with a gap underneath, to minimize the ground effect. or just start with full throttle abruptly and stabilize again when it's high enough

[@eddogq28]

I once used an electric lawn blower motor to do something similar a while back. Brushless and all. I’ll have to link the video sometime.

[@конал-с6о]

[@Ilia-Myromec]

Гравицапа

[@АлександрСерков-к8п]

Гравицапа сама не летает!

[@АлександрКоваленко-и4о]

А пепелац без гравицапы тоже не полетит.

[@конал-с6о]

там аж 4 гравицапы - посмотри, синие по бокам)

[@DODG-Hudsan]

Круто :) очень похоже на этот фильм кино :) kzbin.info/www/bejne/eZ7Kmnt6rNuAjNU

[@TECHnoman753]

Yes lol

[@privateerburrows]

It actually doesn't matter that the servos can't move much faster; you can crank up a derivative factor sky high and actually get faster response without fast compensatory motions. It is counter-intuitive but true. Try cranking up the derivative by big steps, like double the coefficient, test, double it again, test again... At some point you will get diminishing returns. I'd encourage you to do the same with the motor speed control. Additionally, you could try adding a second-derivative component to the PID; which will probably have no noticeable effect until its gain is one or two orders of magnitude higher than the derivative gain. Great project; congratulations!

[@AllAroundTube50]

Kickstarter - all you need is a shell for this and you have the perfect kickstarter or Indiegogo project. You have working prototype which is more than many kickstarter campaigns have.

[@derekseed]

Excellent work! You could revolutionize leaf blowing in the fall.
