H80 Turbojet Engine - Maximum Thrust Test Run

[spike232fly]

i have a H20 wasp never been run. where can i get an owners manual/instruction manual? what rpm censor can i use?

[obilaser]

@spike232fly I can provide the H20 manuals in electronic copy for $25 USD, printed copy is $50 plus shipping. Contact me directly through my website.

[circusboy90210]

are these units faa certified?

[obilaser]

@circusboy90210 These engines ARE NOT FAA certified. It is unlikely that these engines will engines will ever see enough civilian use to justify the cost of certification. Until sufficient sales are generated to justify such expenses, these engines must be utilized as "Experimental".

[circusboy90210]

@obilaser so if I wanted to use that in a db-5j i would have no problem??

[obilaser]

@circusboy90210 Yes, a pair of the TJF150's would power the BD-5 very well. Just one TJF150 would be a little bit underpowered.

[circusboy90210]

@obilaser what is the biggest unit you can make in that weight size range.

[obilaser]

@circusboy90210 Presently, my largest production engine is the TJF150. It will produce 150 pounds thrust all day long. It can produce up to 175 pounds thrust for short duration. The TJF150 is 8" in diameter and 20" in length, it weighs 22 pounds

[circusboy90210]

@obilaser would like to face book you this interface in clumsy my email is my username@gmail.com

[obilaser]

@circusboy90210 I don't use facebook... You can contact me directly via rob@obilaser.com

[lordzkonyx]

could you send me some blueprints of a 5'' in diameter and 12'' in length, please and thanks, it''ll be very helpful and i'm in highschool, and i'm trying to create a small jetplane vertical lift craft, and starting out from a small jet engine, i could understand the concept for fully.

[obilaser]

@lordzkonyx I can sell you a construction manual for the H20. Cost is $50 USD. Contact me directly via email.

[lordzkonyx]

@obilaser for this engine above or something else different

[schl0tte]

Now that's one expensive hair dryer :D

Insane!

[flyingarrow1000]

Good testrun.Some one have the contact to Phill Heward?ore the company wich produce this jet engine.

Thanks

Flyingarrow

[obilaser]

Phill ceased operations in 2008

I am now licensed to provide these engines.

[COD5252]

dont take me negative but u should try something more large

[obilaser]

I build the H80, TJF100 and the TJF150.

The number represents the thrust in pounds.

[crsereda]

Approximately how much larger is the JTF150 compared to the H80?

[obilaser]

The H80 is 6" diameter by 19" length, it weighs 10 pounds.

The TJF150 is 8" diameter by 20" length, it weighs 22 pounds.

[COD5252]

people make turbojet out of small turbochargers no one have ever tried to make something bigger and more customized like what now im going to make one.Frankly speaking there is no use of such engines other than planting on a small gokart or bicycle.

[coolestdude80]

Where did you get it?

[obilaser]

I build them here

[diegus012]

cool engine. really dig the close up of the knee at 2:20 haha

[thewebmaster93]

There is obilaser again driving his neighbors nutz :)

[obilaser]

Phill has ceased operations at Heward Microjets but I have now acquired the rights to produce these engines here in Connecticut.

The H80 is available for ~ $10K USD

The TJF150 is available for ~ $15K USD

What type of bike do you have?

[OtakuBozu]

what about the H20? Also, can any of these engines use hydrogen as a fuel?

[obilaser]

Custom fuel system but it can be done

[tomosterreur]

how much does that cost? and what would happen if i strapped one on my bike?

[f15mig27]

Nice turbine, but buy a new cameraman!

[obilaser]

Well, I know the video is crude but my friend shot it with a camera phone! I think he got nervous when he realized how powerful this engine is!

[RyuDarragh]

Get a pair of those and you could make a *real* jet pack with more than a measly 45 seconds of lift or fans bigger than the pilot :)

[lordfly88]

Where can I find some info on the H180?

[obilaser]

This is a good question, apparently we don't have anything published! Contact me directly.

[scottaspect20]

hey can you give me som info on the H180

[lordfly88]

Are there any turbojets like yours that produce somewhere around 120-150 lbs of thrust?

[obilaser]

Yes, we have the H180 which will produce 160 lbs continuous and about 175 lbs max.

[Helivz]

Wow, how thirsty is an engine like that? Perhaps it will go thru a gallon of fuel in three minutes? Put that on the back of a bicycle and you won't have to pedal uphill.

[obilaser]

It's pretty thirsty, about 2.3 liters per minute or something like 220 lbs per hour. But you generally don't need full power all of the time.

It would be a bit much for a bicycle.

[Helivz]

Thats like more than one of those two litre, plastic soda pop bottles in one minute, full throttle. That is thirsty.

[Elantrix]

Do you have type of gauging to get the temperature of combustion chamber and exhust? if so what are you running it at for max. power because it looks like it's reaching past 815C mark by the red glow from the steel nozzle and if you continue too long at that temp. you melt your turbine blades

[obilaser]

During this run, the engine is really getting beat on. It is running at 130% of the design rating! The nozzle EGT is ~780 C so as you mention, the turbine and guide vane are very near the glass transition temperature of 913 C.

Any hotter and things melt down!

[aflacduky]

you can buy a surplus f1100 f16 jet for that LOL

[obilaser]

1) Never heard of an F1100

2) You cannot buy a surplus F16 as a civilian

3) I can buy an F16 as a military contractor but it comes without an engine, electronics or nose cone (radar dome)

4) An F16 costs $2 million USD surplus, $8 million new (I checked, just to be sure).

[aflacduky]

f1100 is GEs number military uses F100 you can buy the engines - some parts we got one for our shop and cut it open so the kids could see the compressor and burn cans it cost 200$ lol it was worn out but you can even get them from other countrys that are still air rated just not for 200$ more like 200,000 if you find the right person

[obilaser]

OK, fair enough!

And $200,000 for such an engine is a great deal. Too bad the support parts cost so much!

[aflacduky]

oh yah your right on fuel pumps 100,000$ fire coils 13,000$ "if you could get them" LOL

starting system all that you and i couldnt get to save our necks HEHE i will say this its a well built engine the F100

[aflacduky]

lol 15,000 thousand dallors us LMAO tear apart a turbo charger and build your own for 600 dallors MAX lol 15,000 ya right

[Validole]

I'd seriously like to see you try that without melting your turbine blades on first try... turbocharger really hasn't got the best blades for this :D

[aflacduky]

theres a man that build real good jets and he used mod turbo he coats the turbine blade with some kind of high temp ceramic coating and rebalance them he built one that was 285 pounds of thrust and it looked very well built streamline and light he has a test clip on the web he states over 100 hour op with no break down on the coating ive seen the clip and its a very smooth burn and well built but come on 15,000$ US what would you do with it Glider its to small, RC plane its to big! just saying

[Validole]

They make pretty darn big RC planes ;). Don't ask me how they fly it at those speeds...

Well, can't really comment on the turbo2jet engine conversion, never seen it myself. Sorry, suppose it is possible, but I'm a little skeptical. But hey, as long as _you_ know it's true, that's all that matters, right?

[aflacduky]

well google it i dont have time to shoot the sh#t but the turbos that are stock do fail i was just yaking about spending 15,000 dollars to buy this thats all

[obilaser]

Our engines are too big for R/C models. They are used for military UAV's and civilian, manned gliders. The hobbyists cannot afford this technology yet (although some guys are proving me wrong there).

BTW - I can pilot a UAV up to ~ 300 mph, after that I use the flight computer to do the job.

[Validole]

Hobbyists generally don't see which way their planes are turned beyond 150 m (or 300 m if it's a big model). Makes it really difficult to operate fast models without some in-plane video system or avionics. I can see why that is not a problem with UAV-s...

[obilaser]

I couldn't find the links to this engine. Please provide them here.

I am not aware of any stock turbocharger the can produce the mass flow required to generate 285 pounds thrust unless he is using an afterburner which will utterly destroy his fuel economy.

[obilaser]

Turbochargers are OK for building engines, just keep the EGT down. What makes them weak is the poor guide vane design and the very heavy cast iron volute (not usable for flight applications).

[obilaser]

LMAO right back at ya pal...

I spend more than $600 on the ECU, fuel pump and control valves alone.

If you can build and sell any Brayton cycle engine for less than a few thousand dollars then call me, you're hired!

[deauzie]

what does it cost ?

are u making bigger units like 150-200 lbt

[obilaser]

~ $13,000 to $15,000 USD

Turbojets to 200 pounds thrust
