Small But Powerful: The Pratt & Whitney TJ-150

Small engine. Big power. Meet Pratt & Whitney's TJ-150. This high-performance turbojet engine is designed for expendable and limited life operation in missiles and unmanned aerial vehicle applications.

[@Blime2913]

Hmn! I wonder if this type of powerplant can be useful for a private home built ultralight kit plane. Im sure 200 pounds of combined thrust from 2 of these engines might be sufficient motive power for an ultralight kit plan that humans can fly!..💡😊😆.

[@alodiacaitlyncalimlim9071]

SAD to say the military don't want us to have it.

[@electromechanicalstuff2602]

They don't have starters. They use a one time use solid booster to light off the compressor wheel

PBS TP100

[@daddyplankton5855]

Plus spares maintenance all that isn't done cause it's supposed to be one use my guess is it'll only last for a small time then fail

[@worldsmostwantedkiller]

The Sonex JSX 2 jet uses a PBS TJ 100 with 130 kg of thrust, ~ 300 lb maybe? You can have it for 120.000$

[@microcolonel]

I had no idea P&W made engines this size. It'd be interesting to see high bypass turbofans in this range of size. Seems they could be a lot more reliable than other small aircraft engine options.

[@danielnofal]

You don’t need long term reliability for a missile

[@mehrschwein7378]

no, but it potentially sits for a long time before use.

Williams international F107 makes up to 1000ft lbs of thrust similar size 100lbs

[@MarkiusFox]

It would be interesting to see these adapted to automotive and small marine use.

[@creativityworld6781]

PBS velka TJ-100 in same size and produces almost double thrust

[@B61Mod12]

and they have the TJ-150 now also. 150KG of thrust.

[@EUK007]

The PBS TJ-200 is coming soon with 200 lbs of thrust. Putting 2 of those engines in a Light Sport Airplanes would be a fantastic sight.

[@worldsmostwantedkiller]

​​​​@@EUK007They even did a partnership with a company and make a 300 kg of thrust version, put 3 of those on a wearable aircraft and you're going Mach 2, and also the TJ 200 has more like 440 lb of thrust, 200 is from kilograms

[@มดแดง-ฃ3ข]

ใช่มันน่าสนใจมากถ้าติดตั้งใบพัดเข้าไปในวงกลมนั้นมันจะไปได้สูงกว่านั้นอีกเยอะ

[@yolo_burrito]

Is this the same as the PBS TJ-150?

[@AliAhmed-tm1jf]

Yes

[@deborshikashyap6745]

PW engine fails more often but CFM and IDE don't..why like that 🤔

[@GrantOakes]

The BD-5J had a Turbomeca engine producing about 200 pounds of thrust. For a small homebuilt aircraft this engine would need at least that much or more. Costs would most likely be $50K or much more!

[@NIOC630]

lol, 50k... Even small conventional aviation piston engines are more expensive.

[@GrantOakes]

@@NIOC630 Very true, but weigh MUCH, MUCH more and aren't going to deliver the thrill of a jet engine.

[@NIOC630]

just wanted to point out that your 50k estimate is waaaaay off ;) @@GrantOakes

[@worldsmostwantedkiller]

​@@NIOC630Look at Jet Cat P1000 Pro, 20 and something thousand dollars engine 120 kg of thrust Swiwin also makes a 800N engine at ~16.000$ and you can put them on a Sonex JSX 2 wich originally is for a PBS TJ 100 wich is a 300 lb class 60-70 k $ engine (Turbine all)

[@orthopraxis235]

Is the priority on designing engine longevity really high if they are going on missiles?

[@meltdown7259]

Congratulations patt and witteny

[@RacingMeyer8]

Where to buy. Engine life? Costs a house?

[@LNo-re7sk]

Why not a small turbofan engine?

[@SuperYellowsubmarin]

Reliability, but not longevity !

[@josephdupont]

How much

[@ricksteinhoff3496]

Give me one and I will tell you how far it will fly

[@MrBen527]

Can I have one for my go kart please?

[@The_Conspiracy_Analyst]

Looks the perfect size engine for a jetpack....

[@TheZipp1]

Reliability up to 2 hours.

I used to work at William's International rebuilding cruise missile engines.

[@kazansky22]

@Exuma Guy alot of them are used as practice shots, dumped into the ocean ect... They get recovered and rebuilt.

[@izabellaraczkowska7542]

I want one

[@phoneticau]

Will you sell to home builders for ultralight jets ??

[@DrStoooopid]

it'd never work unless you made it a turboprop, otherwise you'd never make Part 103, just based on speed alone.

[@siggyretburns7523]

That sucks though. A bad assed engine built for one flight. Bring back the V-2s. Alot cheaper.

Stolen design from Chezslovakia

Chezslovakia does not exist anymore since 1992... This has nothing to do with PBS's TJ150 from the Czech Republic.

[@Agent-000-0]

@@harrisn3693 ​ Harris Naseem The Pratt & Whitney TJ-150 is older than PBS TJ150 and is based on the Sundstrand TJ-50. For the PBS TJ150 it literally says "NEW" on their website and under their promo video on youtube. The Pratt & Whitney TJ-150 first flew in 2009. They look different and have a different power output. The PBS TJ150 is way bigger, has double the weight and more than double the power. You said its a copy, prove it, don't try to fool me with "do your research". "AIPAC shill" -- What has this right-wing Israeli lobby to do with this? Nothing! "It was used on target drones for USSR back in the cold war." -- Not even according to the manufacturer. "Also, stop reading Tom Clancy books, your false patritoism is showing." -- Well, I'm not from the US...
