What is the smallest turbine engine that is available to the public? What thrust category does it fit under?



(please note that this is not Richard Newman aka (eletrick))

The smallest and lightest production motor would be the 44mm wren. It delievers 7lbs thrust.

Vin...

Thanks for the fast reply. Who sells them?

RNewman,

You can go to: www.Wren-turbines.com
to learn about the MW44.

Soon the MW44 and MW54 will be available through the U.S. distributor, Jet Hangar Hobbies: www.jethangar.com

any small 7 pound thrust turbines ready for sale at this time.. the wren seems to only be going to a select few on a waiting list. and no price or other info is mentioned at the web site. and no update info on the simjet 700 either.. guess it's a waiting game.

At Florida Jets 2003 there was a micro turbine ( Micro bee ??) half the size of the Wren 44/SJ 700. I held it in my hand, 3 1/2 pounds of trust this little turbine produces. Really amazing

I'm sure some one took a picture of it as they had an open display of it.

I also was able to see the Simjet 700 for the 1st time, and right beside it was a JHH Hawk ARF, so I was able to put the 700 inside the Hawk to see if the Simjet 700 was a good match for the Hawk.

According to the ads published on Dec 02/Jan 03 issue of IRCJ, the price for wren 44 in UK is 1,450 Pound ready to run.

the distributor for Wren in US is:

JD enterprises, (650) 3359-0406

www.jdenterprise.net


Figures of the tiny wren 44 also published on the ads:

Thrust: 3 kg
RPM: 190,000
weight: 460 g
diameter: 74 mm
length: 150 mm
fuel consumption: 103 g/min

don't know whether certified by AMA or not.

Robert, on the Artes website there is a size comparison between the bee 50 and the smaller bee you saw. It makes the 50 look like a monster!!! Right now the Artes JF-50 bee motor would be a good choice for a small project. Its only 80mm, very light and is full auto start. Rated at 11-12lbs thrust too. I believe this motor is in the certification process with the AMA??

Vin...

F900, I think the 'Micro bee' that you are talking about is called the Nano Bee. I'm not sure what you saw though. If it is what you saw, it is made by Artes Jet Microturbines.

THAT SOUNDS GREAT! but hey, do you know when it will be on the market? its freakin 2005 an NADA. im so impatient, you can stick that in like a kyosho f-16 and voila, park flyer turbine. anyway, email me at [email protected] if you find anything. ive search about this mysterious turbine and ive found almost nothing.

??? NADA? Simjet 700 and the Wren 44 have both been available now for many months... contact Simjet or wren and get your order in...

how far back did you have to go to find a 2 year old post??? A lot of what has been written is now history.... You can also check out the ArtesJet site to see what they are doing with the Bee / NanoBee......

Guys,

I think the smallest turbine in production is called Nanojet T32 Kolibri, and is availaible at:
http://www.lambert-modellturbinen.de...riebwerke.html

Nanojet T32 Kolibri Price 2436 Euro

lengh: 120 mm Masse: 185 g
thrust: 15 N (1,5 kp) at 243 000 1/min
compression ratio: 1:2,2
for planes up to 1,5- 3 kg.
weight: 750g, including pump and gear.

Has anyone seen one in a model flying

Dont ask me which turbine this is....just found it on the net somewhere.

But it sure looks small.

That is Ewald (Pegasus)Shuster's 4LB homebuilt in his mini "Hotspot".

Does he plan to got to production, or sell it as a kit ?

Ewald doesn't plan on kitting that little engine, or I should say the lat time I heard anyway. it is a one of a kind!

Too bad I would have loved to own one of these...
I guess I'll have to go for the T32 Kolibri then !

Guys

I have a Nano T32 arriving any day...I'll let you know how it goes

I have an airframe waiting so we will see.

Dave,

Post tons of pics, and let us know how it performs...
How did you know about this turbine ?
When did you order it ?

I saw a prototype at JetPower in 2003. (everyone should visit this Jet only trade event in September!)
It wasn't run at the show

I remembered it end of last year and emailed Martin Lambert to see how development had gone, little info came back,but he said that he was finishing tests and motors would be available early in 2005...
I confirmed the order around 2 months ago and sent money...

I thought nearly quarter of a million RPM sounded fun!

I'll keep you posted

Dave

Can't wait for your news...
My MW44 already runs at 190K RPM, I believed it was huge... a quarter million, man, you beat it all...
It must make a hell lot of noise though !!!
