I was going to suggest that Tory might be a Monkey Island fan, as Guybrush says it repeatedly....but apparently it's from Get Smart which likely influenced both!
More speed doesn't actually get you anything. The engine needs to have enough torgue to spin the props. If you gear it then the engine could easily stall.
Funnily enough, with the quadcopter tech and flight electronics today, you probably COULD build an electric jetpack from plans on the internet. Gravity Industries Jet Suit aside (which, incidentally, Adam's been flying on), multiple drone based jet packs do exist.
There is still the safety concern. There is a reason personal flying devices are never going to be a commercial product. They are too steeped in liability. Remember people, if your device fails while you are in the air, you are falling to the ground with no safety net.
They need some sort of parachute mechanism that auto deploys when it detects its falling past a certain rate. Problem with that, there is a minimum height for parachutes to work properly, and even then, what's going to help you below that minimum altitude?
That was the best part of the show I watch it when it aired that year why I'm watching it now is I want them to use that more powerful engine with shaft drive not belt and see what it can do
I speculate that the jetpack test failed because the propellers were not spinning fast enough. Someone building a machine like that would first check the specs of the propellers, in particular the fastest speed at which they generate thrust efficiently. Then the builder would select a gear ratio that would make the propellers spin at the highest speed allowed at the engine speed with the highest level of power output. It's possible that the engine would not be strong enough for that, so there might have to be experimentation with gear ratios. With no professional background in aeronautical engineering, I speculate that the main purpose of the cowling ducts is to prevent turbulence, as well as directing the thrust. Drones fly well enough without them. The Mythbusters made a good presentation, but I'm not fully convinced that the myth was busted.
The myth though was that someone without a background in aeronotics can do this and the mythbusters do have a lot of experience in engineering and a lot of contacts. If they can't do it then it's pretty clear some middle class guy in his garage can't do it either and that was the myth. That a ducted fan machine can lift a human is no myth, I mean all you have to do is scale down a helicopter. The question is can an average Joe with only a lose idea of mechanics and a single trip to the hardware store do it?
Cowlings are about scale and also compactness. For this application they wanted a lot of lift in a small form factor. With a helicopter you would just put bigger rotor blades on it and with a drone you can get more thrust for less additional weight by just adding an additional propeller. With this design though using a single engine having like 4-5 fans would require so much mechanical complexity it would not be reliable and would have added too much weight. They didn't yet have the powerful batteries and electric motors that allow drones to have up to a dozen rotor blades without being too heavy or become too unreliable. So if you can only use 2 rotors and they can't be too long then you have to add cowlings to maximize the thrust from them.
I'm going the tin foil hat route on this one. With it being TV and the FAA involved probably had the biggest hand in why this wasn't a successful experiment. Adam and Jamie are waay too smart to not be able to figure it out especially when smart guys like them are actually interested in the project.
Personally I'd love to see an update on the Williams X-Jet, also known as the flying pulpit. I know someone had bought the rights and patents for it. Thing looked amazing.
Just a comment on an interesting effort with this one-men flying machine.. The stability experienced by the Hiller machine and the De Lackner Helivector was due in main to keeping the cemtre of gravity ABOVE the rotor system. To install the engine low in the craft would make the thing VERY unstable. It might seem to be the logical thing to do but entirely wrong in this case.
once i was bored so i got a few people to attempt some "realistic" flying in some game and ngl, humans are relatively horrible at flying and considering that we haven't evolved at all to fly and even birds tend to crash against the walls sometimes, i can easily tell that giving people an access to flight irl would have disasterous consequences, at least we would have to train people first and then be more strict than in case of cars, perhaps just as much as it is the case for planes... and even then you have to make sure that there's absolutely zero technical issues and have backup engines
The Primary obstacle for personal flying machines is the incredible complexity of piloting in 3 dimensions. Look at all the accidents on roads, where there are strict "pathways" and rules - increasing to 3 dimensions would make traffic control impossibly complex. And that assumes the actual craft is somehow flown "automatically" eliminating the need for the pilot to have the extensive training they now require.
Why did they decide to move the engine lower on the frame? I thought the pendulum effect didn't work on helicopters because the thrust is not vertical like a fixed hinge.
They maybe would got some more Thrust, if they played with the gearratio of the Belt drive and or the Dimensions of the propellers (bigger or smaller but with less or more angle on the blades) BUT I am amazed and impressed how much has changed in these few years. Today we have working Jetpacks of different kinds. There are Electric ones with RC Brushless Motors. There are Turbine powered, also on base of RC Jetengines And I belive I saw some with gas engines. Also there are kind of Jetpacks like a German Guy with a flying Bathtub with RC Equipment. Its a manlifting Quadcopter.
That flying machine duct fans reminds me of my sump pump when it jammed with sand and talking to a wonderful DeWalt tech about the tolerances. I think it would need precision measurement of the blue foam. I am not in any way blaming Adam. I expect you need to spend in excess of $50,00 to make this accurate to 1/16"
Sorry but got to ask....... Wich 3d printer is you go too printer. Ive a neptune 4pro (all your fault😊) but at the time was looking at the bamboo range. Any chance of doing video with your thoughts on all your printers . Always great videos . Thanks
To the pyramid myths, something scientists found out and what me really surprised is that the Gizeh pyramids have (like mountains) such a big mass that they do slow the time around them a tiiiiiiiiiiiiiiiiiiiny tiny bit. Not noticible and not measurable unless you have billions worth of lab Equipment but i think thats pretty cool. Like Einstein sayd, big Objekts can influence time and room. Like light bends around massive stars and black holes.
It's a shame they didn't research outside the US. In NZ the Martin company created a workable jet pack. Similar to what they did, only it worked. Could fly to 5000 ft at 60 mph tested and was quite stable with a parachute return system. But hey. If it's not invented in the US, it's just not invented...
Did the jet-pack reappear in the later episodes? Like the pneumatic actuators from the marching bridge myth EDIT: Found one in the build team using it as a windblower, and in the Mythbuster exhibition
This was a good episode, they were very close. Could the ratio be changed to spin the rotors faster, it looked like 2:1 reduction. Maybe if constructed of tubing like aeroplanes are rather than girders the weight would be significantly reduced.
Even if those things were working great, be safe - and affordable (spoiler: They're not) - they still have the big problem of terrible fuel efficiency. Unless we have loads of free energy - these things will never be real. But hey - if I'd dumped 200 million USD into this - I'd probably believe that, too.
And the idea isn't new. The whole "flying cars" idea is around since the 50ies - at least. And it still all comes down to efficiency. Unless you're able to build a VTOL glider - it won't happen.
@@themonsterunderyourbed9408 Yeah - right. Where did I left it? Behind the time machine, left of the warp drive - or near the trans-dimensional travel device?
I think that if you could increase the diameter of the central pulley that is on the central axis of the jet pack, it would considerably increase the rpm of the propellers. There was just one thing missing from the video and descriptions. Where did you get the source for this project file?
Belt slipping? maybe variable pitch fan blades needed in order to maximise efficiency at max power? (I used to be a hovercraft builder many years ago and am jealous!)
It's kind of amusing because with current electrical engines this isn't a problem at all. Have you seen the platform ones with the small propellers that people get off into the air with these days? Turns out that what you really need is a better motor because ICE's efficiency is ~40% at the very best and have a rev limit, electrical engines ... not so much.
37:18 Jamie: What do you want to do? Pave the whole planet with roads. Highways are getting full. Americans will literally try everything to solve traffic instead of actual public transportation lol
That private Helicopter would maybe fly easier If you increase the Diameter of the Rotors (and ducts). You get way more airflow/mass and dont get too mich weight ontop
The real problem with this is the props were not spinning fast enough to generate lift. The engine driven pulley needs to be 10% larger than those driving the propellers. Another way is to use propellers with more blades.
Anyone know what the graphic is on Scottie's shirt at 8:42? I've definitely seen that character in the purple dress before and it hit with unexpected nostalgia
LOL I remember seeing this "pyramid power" thing on Brazilian TV back in the days and I did put a banana for a month inside a paper pyramid. I dunno it did rot but not so much so kinda worked? Or was it a placebo effect of sort? Anyway it was quite unimpressive.
The first big design mistake is not to use rotary colt propellers, we need too much power and the lack of carbon fiber makes it unfeasible ...... I love this program the most

Also why didn't they use gears to increase the speed 🤔
The extra weight would probably just have negated any increase in lift.
The drive shaft split already reduces like 17% of the power of the engine, putting gears on it would probably not make a difference for better.
You just would need to put a bigger pulleys on the engine for the belt.

We have a say in the RC plane flying community, “Take offs are optional, but landings are compulsory”, landings ….that’s your problem!
That private Helicopter would maybe fly easier If you increase the Diameter of the Rotors (and ducts). You get way more airflow/mass and dont get too mich weight ontop
Now, there's real personal drones
And jet packs. th-cam.com/video/nj-Iwv5NJKg/w-d-xo.html
I do still wonder if there'll ever be a backpack based jetpack like the Rocketeer... 🙃😅
The real problem with this is the props were not spinning fast enough to generate lift. The engine driven pulley needs to be 10% larger than those driving the propellers. Another way is to use propellers with more blades.
41:46 why does Adam have a Jafar knife (for all you Stargate fans, you know what I mean)?
10:27 this guy sounds all purple-dranked to me...
feeling younger watching this
Really tho lol
@@frankonabigon2974 honest to God
20 years later - hold my brushless high power motor. With modern drone tech it's possible to build one of those.
Anyone know what the graphic is on Scottie's shirt at 8:42? I've definitely seen that character in the purple dress before and it hit with unexpected nostalgia
me and my buddy tried building a jet pack in grade school.....it went as well as you would expect
LOL I remember seeing this "pyramid power" thing on Brazilian TV back in the days and I did put a banana for a month inside a paper pyramid. I dunno it did rot but not so much so kinda worked? Or was it a placebo effect of sort? Anyway it was quite unimpressive.
10 mil dollars?! Sure not
I heard the russian sknny pyramid has more power .
the Bell jet-pack was in one of the early James Bond movies
14:54 Adam reminds me of a monkey witnessing a magic trick lol
Did you get the build over to the Nice Mr North E. West to accompany his drawers full of plans?
It flies without a pilot, so they made a giant heavy drone.
The first big design mistake is not to use rotary colt propellers, we need too much power and the lack of carbon fiber makes it unfeasible ...... I love this program the most
Jet engines! Modern compact jet engines seem to work. If only for 15 minutes. th-cam.com/video/nj-Iwv5NJKg/w-d-xo.html
Im sure the first jet pack was made by someone at home
North East West - best name ever
Has a real direction to it
Sorry Kanye, someone thought of "North West" as a name before you did
That pyramid one was borderline insulating
No, we do not acknowledge that so-called scientist. But we have Škoda, Tatra and Pilsner Urquell.
Any TH-camrs who attempted to make a DIY jetpack or similar yet?
I think they should have tried an electric version. Probably a lot lighter,and just as powerful. They sell motors for paragliders that are electric.
3:20 "Extremely dangerous" 2024 with available ones on the market, police using them and taxis ready to be deployed XD
Huh, where are police and taxis using jetpacks?
Where’s our flying cars!
Bro revived Czechoslovakia to prove pyramid woogabooga is real
Why wouldn't you put a groove in the ducts so there is zero gap between the fan and the duct?
Forget a jetpack, get a power glider.
Fan on your back and a paragliding chute
And then parachute into a stadium in Israel and run for the nearest baby?
They are so clever they could not replicate the School Girl Bedini convertor, that a school girl got a A doing lol!
7 years and 10million 😂 sounds like the guys had some fun wasting time at the office. Drone setup can now be done for 20k
