That's true, imagine the cost of fuel alone XD These engines are simple but due to having single compressor and turbine it's really limited in thrust unless you spin it up to really dangerous speeds also lack of turbine stages means low efficiency
Ikr! But that’s just the way they design em, if you want 2-3 stage then you have to either design and manufacture it yourself or maybe there’s a few on the internet
Are these turbine engines not subjected to the high temperatures of full size radial turbines. if they are subject to high temperatures, how does aluminium cope with the high temperatures. I did not hear the presenter discuss titanium parts in this turbine.
Titanium is only good for low temperature stuff Hot side (turbine stator vanes) are made out of inconel as it doesn't lose strength when heated and it doesn't shrink and expand and can take up to 800°C Aluminum compressor is standard centrifugal single stage and will only see temperature as high as 150°C
This is the great work my friend, can you suggest me how can i make it even small, or if you tell me where can i purchase them. i am planing to design one robot using them.
This engine just like the first air - compressor of Sir Frank Whittle / Brittain ... But the real turbine engine was the powered German Messerschmidt Me-262 Schwalbe airplane ... !"! ....
Dante hollow if you are skilled in crafting you can build your own... The only parts you need to buy are of course the materials etc but you cant build the turbines on your own without costly precision tools. So you need to buy them
looks no close to real jet engine.....still hell expansive, also the parts that goes inside doesnt seems to be madeup of expansive stuff...why the hell they charge so high for this... if they think its because of low demand? man the low demand is because of its high price.... drive the price down and you will see the demand moving up high.... im sure that its the high price only which keeps many many aeromodellers out of this turbine thing....and i agree the model piston engines are also complicated stuff..but still under affordability.
1:24 - first blood!
These parts are extremely sharp after machining. That guys blood is all over the air foils.
After 8 years you really helped me a lot like really really a lot very really really a lot
After that i doubt my tin can jet engine will work...
lmao 😂😂😂
Might work, my diy foamboard ducted fan worked just fine for my f86 sabre, but well, the 4500kv motor finally gave uo
I’m designing and building my own VTOL one man jet I can take off from my backyard and take to work… gotta start somewhere bud, I believe in you!! :D
6 hours to build it --- 0.6 seconds to destroy it

A thing of beauty
All hand made from scratch, that explains the cost, looks easy. Looks!
Questi si da vero sara i motori del futuro😘😉😎
Amazing
What Cnc was used for that
has anyone noticed these little jets operate like a centrifugal engine like Frank Whittle`s first engine
Enterprise206 the centrifugal design of the turbojet is not as common anymore but is much simpler and easier to make, thus its usage in small jets
you are right. axial flow compressors are common now days.
very good.
the turbine that comes with blood
Is it P140 maybe?
this is sick.
I like this narrator because of his bad puns :3
There are multiple lacerations on his left hand.
donde puedo pedir unmotor
Is it me or does it look like the guy in the first two minutes of the video cut himself a lot making the turbine part?
Yes I also think he cut himself
If full size jet engines were this simple /light you wouldn't want to fly commercial.

.
the hard part isnt making the engine the hard part is the amount of knowledge one needs to design it and put to work for several hundred thouand hours of work even before you can actually BUILD the first engine ...

Crazy how these are now a big part of the Ukranian/Russian war for long range drone bombers
I like to eat caviar while I fly my jet.
how much do they cost? because I love them, and I want to buy.
about $4,000 each
Can l buy it from egypt ?
جيد جدا
Damn no wonder there so expensive
How come only a single stage compressor?
Ikr! But that’s just the way they design em, if you want 2-3 stage then you have to either design and manufacture it yourself or maybe there’s a few on the internet
👍🏻
6 hours?
The things cost $2000-$6000. must be a lot of overhead and high profit margins...
+Doug Fresh not really i work with cnc machines they
are capable of machines high precision parts continuesly :)

I tried making my own. and heaven has a computer
Ciao Salvatore,come stai?
How much does the engine cost. i need 8 of them for my Military School projects
about 2,000 dollar for one
More than that depending on the size. The model in this video is a Larger type model and would cost around $4,000.
That dude's bleeding all over the turning blades!!!
Did anyone else notice the wobble at 4:54 ?
Since the one at the end is a non-working cutaway display model, I doubt they spent the time balancing it.

This is the great work my friend,

one will cost about $4,000
@Kuku (Hindi) not 28000
Its around 2,80,000.(2.8lakh rupees)
@@asmityadav4216 thats someone's yearly salary.
Sorry for the injury
use a ball bearing with the high temperature seriously ?

that one is very expensive!!!its about $5k
I wished to had one....But now its gone.
No you can buy Chinese jet engine only for 900$

Whittle designed the first complete, working gas turbine engine. Germans were first to launch a practical jet aircraft.
It rubs the lotion on its skin.....

$4,000? better get real F-16 :D
I'm sorry but that assembler was sloppy as all hell.

zM: On the contrary. This has all the same basic parts and design of early centrifugal jet engines used from WWII to the mid 1960's.
