@@BOREDFU it is fuelled, u can see the fuel line. Turbojet engines have compressors and a turbine so this is more complicated than it seems and is a cool project for sure 👍👍
What kind of engineer lights that with a cigarette lighter 😂. There are so many tools for safely lighting but you'd think they would at least use a bbq lighter 😂.
@@sakibshaikh07 Bhai the fuck u talking about? This contraption of yours is just a gigantic butane lighter with a fan attached . Where's the thrust? Compressors? Nozzle? Duh
Given the sandals and jeans, three Indian guys and overall lack of safety. High probability this is in India. Safety has never really been high on India's priorities.
They were relying on the laden effect and the transfer of energy through thermal exchange of they're hair fibres as they ignited to not burn themselves .... Everyone in the vicinity should have know better... Will give them benifit of doubt maybe they're igniter failed.. but they could have lit that in a way safer manner...😅
@@danefuentes3877 I’d be stupid not to be. I respect science. Imagine if the people that created the nuclear bomb weren’t “scared of science” and just casually did whatever experiments they wanted. Are you not scared of science 😂
@@Royyalflushnoone even mentioned jet engines. stop talking when you don't even know what the experiment is. you are the kind of person who would call someone dumb for using an umbrella in the sun because your brain can only capture the most obvious connections and anything beyond that is just dark for you.
Есть огнеупорные перчатки, такие продают даже в супермаркете 😂 подносит зажигалку, как будто пытается кого-то прикурить, но в отличие от прикурить сигарету, тут огонь будет гораздо мощнее и жарче, что он даже не успеет руки убрать.
This has been my experience working with engineers. They all want to be hands on in the field until its time to strap the harness on and the tool belt. They’ve got big brains but little common sense
@@kingtut1431Someday you will learn that it is valid to criticize things that you yourself have never done, someday. Until then, never judge a feature length film negatively ever again until you make an entire one yourself. Never judge a roller coaster to be boring unless you make one. Never say a mass produced food is nasty until you also make a mass produced food. Etc till the end of time. 😂
Clearly never been inside an Engineering lab. Students don't care about safety, there are usually signs everywhere. Remember most students are still teenagers...
@@talespereira405 i dont go to parties, also my above statement is true as most projects are just working models they arent safe most of the time, video shows just a model
I’m no physicist but the thing you guys built couldn’t be classified anymore than a propane heater. It’s getting close to the beginning of a jet engine, but plenty of mechanical and combustion figures you need planned out before is gets close.
I think the can is something like hydrogen or oxygen and the guy on the far left is feeding some sort of fuel most likely methane or butane. Not that impressive but to be fair they are like one step off of building a pretty nifty bomb. 😂
@@apoorww1veteran994methane gas is not that easy to combustion like this 🗿 Yakin nahi hota toh padne ka baad picware ka pas lighter jala ka khada rahna 🗿
I made one in my BE finals about 20 years ago, a turbo charger based jet engine, it had an auto starter, spin up was controlled, had a proper forced lubrication system. Good effort folks just ensure you have the basics right.. getting fire is easy, sustained burn on own power, thats what you should aim for. Play safe!
I dont understand, its essentially just a fan with air and fuel. A jet engine compresses the air, with a sophisticated compressor or axial compressor, otherwise your going to get absolutely no thrust. Technically you could use a design of a turbo, they are used alot in making diy jet engines.
Yup...Indian universities. It's why on electronics project videos you see loads of Indians in the comments like "source code schematic pls" "give source code" etc. Cause unis there don't really check so you can just take somebody's project & pass it off as your own
@@flaminmongrel6955The only thing that makes me feel better is showing up to work and training college students who still don't know how to do anything and then going home to fuck your mom.
@@infernaldaedraWhat are you even saying man? I'm in college and helping to further our understanding of the laws that govern jets in black holes by creating simulations on a high performance computer and analyzing the data we get. I know other students who are helping to develop models of Europa's sub terrainian oceans. Some are finding patterns in massive datasets to develop better economic models that we can use to improve economic policy. My sister has created date and models on how different backgrounds and other attributes cause a trend in judges to be biased in certain predictable ways. A ton of research is done by college students, mostly graduate students, but undergraduate students contribute a lot too. And we do all of this for little to no money and with whatever free time we can scavenge.
@@0xSigma "JUST" 18.. I was rebuilding Jag engines at 16 & building my own solid fuel rocket motors.. 18 is university stuff FFS! .. TEACH them.. what a jet engine actually IS ! .. NOT this
I appreciate their enthusiasm for studying turbo fan, their mistake lies in the large output volume which results in instability of the exit pressure, it is not proportional to the length of the tube with the number of fin plates which are useful for increasing the density of the air sucked in. Even though the air pressure from the compressor is not enough to make hot temperature with low pressure which is expected to become a turbojet like an airplane, look again at the planning formula for the expected target so that results and evaluation are maximum😊.
I think you only need to pay attention to the Needs, Uses, Skills and methods of obtaining case studies that are designed by yourself, and some people only assess their results without affecting their performance and engineering science is rich with facts for lay people.
@@aq1184 Yes, I know, because that is one of the objectives of the final assessment in the diploma and I was in that position before going to other stages of education. Utilizing used goods to increase economic value, sometimes even referring to useful recycling. In fact, that's not the only goal to get a high assessment of the final result.
Suggestions from someone with no background in engineering at all: • I would probably make a longer intake for the compressed air so you don’t have to be so close to the engine, like you have the right idea having such a long tube for the fuel injection you can definitely find some way to do that w the compressed air nozzle • More fuel injected, very weak when rotation actually started, again preferably further away from the actual engine • you can definitely find some way of making an electrical sparking system like an electric lighter, but even if that can’t be integrated into the engine use a barbecue lighter
You missed all important points... Key here is calculation, that includes having the correct shape of fan blades and the correct compression takes place at every stage. (Same goes for the turbine stages) This is why centrifugal types are much easier to DIY. Axial type is very unforgiving, you need to get evrry number right within roughly 5 percent.
If the chamber is longer, then the gas must be injected at other end don't mix gas and air too early because it would be bad if it's ignited inside this thin steel chamber
I acknowledge your creativity and effort in building a functional model, but it deviated from the fundamental principles of a traditional jet engine. This is more like a blowtorch. Combustion occurs inside a closed space called combustion chamber, never at the exhaust. However, even with a combustion chamber, the miniature setup would still not be a true jet engine. A true jet engine requires all of the essential components, including a compressor, combustion chamber, and turbine. In reality, flames coming from the exhaust of an engine is a critical situation that requires a rejected takeoff.
The way these guys set up their combustion is no problem, as I've seen many homebuilt jet engines that work perfectly with such a combustion system. Check out the videos on this channel to see a jet engine like this - www.youtube.com/@Praendy. The problem with their model is that they're using a pc cooling fan as a compressor. Pc cooling fans don't compress air. They only *move* air. I don't know what they used as a turbine, so I can't really comment on that, but turbines look just like compressors.
@@xxxkueckxxx Let me put it this way: a blow torch produces thrust, but it is very small; indeed, it complies with Newton's Third Law and, to some extent, a simplified version of the Brayton cycle. Then one might ask, 'If so, can't it be a miniature setup of a jet engine?' In a way, yes, a blow torch can be likened to a miniature setup of a jet engine because both involve the expulsion of hot gases to generate thrust, but that doesn't make a blow torch a jet engine or any kind of GT engine simply because there is no pressurized air. Jet engines are engineered for efficient propulsion, and the main component that makes a jet engine "the jet engine" is the compressor. A blowtorch simply draws in ambient air and mixes it with fuel for combustion. Without a compressor to elevate the air pressure, the flame produced by a blowtorch is relatively weak and lacks the thrust-generating capabilities of a jet engine. Yes, a jet engine without a compressor is essentially a glorified blowtorch. One might again ask, 'Would not the whole setup fly away due to thrust if they added a compressor?' In that case, the setup should be anchored to prevent it from moving or flying away. Sturdy fixtures or structures can be used to keep the equipment in place and also carefully control the thrust by adjusting the fuel flow rate, just like the other student was doing it in the video. Still, it's a great educational project that can provide valuable insights into the principles of jet propulsion.
@@sub-zero185I think you're misunderstanding his point. A turbo jet engine is not the only type of jet engine. For example, a pulse jet engine does not have a turbine or basically any other moving parts at all.
Just because you know general electrics and boeing 777 does not mean it sounds like that,try to be a bit realistic every engine with a compressor section or a turbine sounds like that
