Thread: ~~Home Built Jet Powered Trike~~
02-01-2008 #1Haggard Guest
]Anyone tryed this yet?
I have the complete instructions and a few of the parts needed to build an actual jet engine that will fit on a bike / trike.
I've been pondering this for probably a year now and figure I might as well be the first to go riding down the King George Hwy with 6 foot flames shooting out behind my bicycle .hahaha
This is gonna be one righteous build my brothers.
Any suggestions other than"don't do it!!" will be greatly appreciated.
I've seen approx 20 of these builds online ranging from a 135 mph jet bicycle to ones that are are built on wooden racks and ducttaped together on someones mothers bicycle!!
I'm shooting for some wheres in the middle : )
Heres a couple samples of what i'm getting into.
haha pretty slim on materials he was lol
I've seen these jet engines quite frequently , I believe there for large rc planes and seem to be readily available but might be a tad small and it just wouldn't be the same as building an engine on your own.
They might be a tad smaller than I'd like also ,but 2 would probably do the job!! hehe.
A little of topic but this following link shows a guy thats taken 4 of these store bought jet engines, affixed them to a fibreglass wing that he molded in his garage and jumped out of a plane !!!
This is by the far the most amazing thing anyone has ever built!
How awsome is that and it shows that 2 of those aughta pusha bike fairly well as 4 of them sure do keep him afloat.
heres a real simple looking home job
This next link gives step by step instuctions on building a jet engine
a couple of the many links i've collected on the subject on the
OH!!! if theres any doubt to how the man feels about this watch the next vid haha

that's some crazy stuff!! the flying man was awesome!!!
you are really gonna kick this homebuilt thing up a buncha levels!!
I don't think I can play with you anymore. J/K
Seriously...I can't wait to see what you come up with!!Dave ♂

That was fun. Darn. Now I'm gonna have to haul *** to make it to work on time.

This is my buddy Bob. I helped him with the early calculations figuring out that this would actually work. Those are model airplane jets there, and yes they actually do produce enough thrust to allow the glider to climb. It is as noisy as ten very noisy things.
Imagine, if you will, a car that is stuck in overdrive. Works fine on the superslab, but can't get out of it's own way at a stoplight. That is how all reaction engines work, and that is why turboprops or turboshaft engines are used on lowspeed aircraft, tanks, etc. when you want the power/weight advantage of a turbine engine. Modern jetliners use high bypass (AKA turbofan) engines rather than pure pressure jets, because even 500kt cruising speeds aren't fast enough to really exploit a pure pressure jet.
The jet glider gives a great wow factor at airshows, but the truth is that it is a very inefficient way to power something at 100 kt. Those same engines, with no changes at all would produce almost 200% more power at 200 kt. as they do at 100 kt.
The bottom line is that ANY gas reaction engine (jets or rockets) is a terrible way to power a low speed vehicle...no matter how cool it is!

Wow. I want some screws loose that way now.

It never ceases to amaze me the ingenuity of some ppl.Not particularly practical but who sayes everything has to be practical...why can't some things just "be"
BTW...that Swiss guy was cool......236Kmh(147Mph)...pretty good.

hahahahaaa just kidding but your missing the entire reason for this build.
Can you understand that practicality just hopped the last frieght outta town with that efficiency feller??
I n your last paragraph you mumbled something about a terrible way to power a low speed vehicle.
I 'm pretty certain The term LOw Speed Vehicle is a little outta sinc with my posted thoughts and ideas.

I do understand that a rocket or jet engine will never have the torque or power anywheres near that of a happy time but thats one of the sacrifices I'll have to make I guess.
You do make some legit points though that I also have realised which is why this is a year in the planning
thanks for your interest and input
Also Kelvbo, I mentoned I wasnt going to use those engines as I'd much rather build my own just to keep the whole thing a little less predictable , for safety reasons , you know??~~!!!??

Hey thanks Dave , Van , Philip and Fedor for understanding what this is all about which is simply me exercising my right to push tha envelope, to build and ride what I want, be it practical, resourceful, inefficient, rediculous or otherwise.
is this going to be my full time ride?
of couse not !!
Is this going just a little too far??
Am I going to emmensely enjoy the build and what will more than likely be a few short rides?
You can bet Your Happy Time #^@ I will!!
To shed a little more insight on why I'm doing this ,one of the many reasons that is, , I'm going to paste a pm I sent to a felllow member earlier.
Here it is as follows:
Ya man over a year now I bean dreaming of this.
Thinkin about droppin by the rcmp detachment. do a litte promotin , see if maybe they might wanna sponser a part of this. be real good community relations and pr for them and If I dont , I know a couple or few of them will be ****ed that not only did they miss the build , but also the opportunity of getting assigned to escort me and my badass police sponsered space bike to different venues and functions. hahaaaaa
**** I'll write police all over it and theyll be shakin their heads and laughin so hard at the audasity i dare to show . and they'll realise they been had again cause how'd it look if they up and confiscated there biggest ,baddest showbikehahahahaaaaa after the public gets a good look at it!!!! They'll be so glad to see me back on my almost normal bikes , that I'll be good for years. They'll be tellin the rookies , dont you dare pull him over!!! He'll be riding somethng 100 times worse tommorow if you do so just leave him the **** alone for gods sake!!! hahahahahhahaha

Found it will_start & Scottm after many years of searching(ok ok slight exaggeration there )
Thought the rest of the gang might appreciate a second look.

I say intrigate the happy time to the jet. Have the HT start off the bike then when you approach top speed,pull in the clutch and push that button.
Then you will pass Soccer Mom. Then she will crash into a tree.
It would be amazing.
