Dad was a P&W E. Hartford production engineer. I recall him bringing home blueprints to tweak the changes that were occurring every day. All by slide rule : few or no computers were available. Greatest generation.

[@TyrannoJoris_Rex]

Maybe once they came out with the PW 2000 and when the federal government's support of GE's development of what became the F110 finally got PW off their ass to fix the F100, sure. Before that, no...

[@StigAviation]

Absolutely incredible generation back then.

[@Chris_at_Home]

My grandfather , dad and oldest brother all retired from P&WA. My wife’s dad and oldest brother also retired from there. I worked on the assembly floor at P&WA on these engines for a few years in the late 1970s. Electronics was my passion so I quit and had a successful career doing that in Alaska. I was an avionics technician on P-3 aircraft in the early 1970s.

[@ghose0809]

Stig, as a former jet engine mechanic in the USAF, I just wanted to say you did an excellent job explaining the engines. These are quite a bit different from what I worked on, the PW-F100-220/229 on F-16's, but the operating principle is the same. Thank you sir, you brought back some great memories!

[@StigAviation]

Thank you very much, and I appreciate you being here.

[@OurPalawanExperience]

Worked on the JT8D for 45 years. Overhaul and test...retired now but I had an entire career on this great engine.

[@StigAviation]

Then you are a wealth of knowledge my friend. I hope I did this video justice by doing this breakdown correctly in your opinion.

[@NBx-th1rt]

Hi, former engine mechanic here. Used to work on CF6, V2500, PWC 300 and 500 series. Greetings from Germany 🇩🇪

[@StigAviation]

Thank you so much for being here and watching, cheers from LAX

[@RobertHolland-z1y]

I was born and raised in Brooklyn, New York. I miss the sound of the old Boeing 727's 737's. My first time being a passenger in an airliner was in 1982. Piedmont Airlines. Boeing 737-100 or 200. Not sure. My seat was right behind the right wing, I believe. That "clamshell" thrust reverser was SO awesome!!! Stig, thank you for this post. Brought back old memories.

[@StigAviation]

@@RobertHolland-z1y glad it brought some fond memories for you. It did for me as well. Hard video to make too. Holy cow that was a ton of info i didn’t expect to talk about.

[@nickh2519]

I do believe the only customer for the 737-100 was Lufthansa, and they still had all their fleet in the early eighties. So I guess you went on a -200. All the best

[@mauricepowers8079]

DAMN...I flew on Piedmont back in 70', 71' and 72' when I was on TAD orders or on leave when I was in the Marines. I would always fly one of their Turboprop puddle jumpers and hub in Atlanta. We jumped in and out of a few grass strips in the Carolinas with them. Service was always great with them. Affordable too. $33 for a one-way ticket from Jax NC to Jax FL...NC to Bradley Field CT was $38? It cost me $22.50 for Gas and Tolls to CT when I drove to CT on the weekends. The good old days.

[@RobertHolland-z1y]

@mauricepowers8079 thank you for your service, very much appreciated. 🇺🇲🇺🇲

[@litz13]

The "WHAM!" when a JT8D clamshell shuts cannot be understated. Tremendous force.

[@StigAviation]

We did a test one time to see how powerful it was… watermelon vs the JT8D TR. All I have to say is that we were eating watermelon after the test. 😅🤣

[@litz13]

@StigAviation like I said - WHAM!

The work this man does when he's on vacation! Stig: Have you been to the Blackbird Airpark in Palmdale? They have a P&W J-58 engine there along with the SR-71 and A-12 that it powered. It is a beast.

[@StigAviation]

Yes I actually have been there, I even got some old footage of it but it’s in vertical format. I have to go back once again to do a proper walk around. Stay tuned for that

[@rogerwalnut]

When I lived under one of the departure flight paths from Memphis airport, I *always* knew when a JT8D-powered aircraft was taking off. Shook the windows! I loved it every time.

[@StigAviation]

At one point in LAX they didn’t allow them to fly in or out past 11 pm because of the noise 😅

[@shyammohabir8283]

This was a master clinic on the JT8D engine - excellent delivery Stig!! Thanks for sharing ..

[@StigAviation]

Much appreciated. Glad you enjoyed it!

[@SC457A]

I used to love watching the thrust reversers do their thing. I always try and sit where I can watch the wing do wing things and still be a kid and see the ground. Im such a kid lol.

[@StigAviation]

Don’t worry I feel the same way, it’s pretty awesome to watch it

[@708mattt]

My AIM campus in Chicago got a JT8D from American Airlines in March 2023, it sits in our hangar and I was one of the first students to see it

[@StigAviation]

Absolutely phenomenal, that is a great engine to learn on. And I hope the video helps you understand it better

[@danielbonilla3195]

That iconic sound of the JT8D mounted on a 727 sends shivers down my spine, such a beautiful piece of machinery with such a beautiful sound, it’s a pity we don’t see them around anymore, although in my country Colombia there are still a few Boeing 727s freighters still flying with Aerosucre

[@StigAviation]

It’s an absolutely incredible aircraft and engine

[@junktionfet]

A truly iconic engine. Not the high tech high efficiency things we have today, but no less amazing and important. And I miss the old clamshell reversers

[@StigAviation]

Those old engines were just pure unadulterated power. Do you wanna go faster just add a whole bunch of fuel, and watch it take off like a rocket 🚀

[@normanpaterson]

I'm a GA pilot we love you mechanics. Owner of my field used to fly the Lockheed Constellation, big engines. Being a GA pilot investigating flying jets, learned, and almost obvious, piston engines are more complicated, many more moving parts.

[@StigAviation]

Piston engines are very simple actually, well to me that is, it’s like sticking an air cooled flat 6 on an airframe. If you know how to fix your car you can fix your GA bird. Now on jets it’s a bit more complicated. But still simple in some ways. Both beautiful tho both fun to work on.

[@jetcom1121]

The best engine ever !!! I love the sound of the JT8D's !!!! Todays engines sound like Hoover Vacuum Cleaners !! Thank yo for this video !!!

[@StigAviation]

The old JT8D’s were true workhorses and made a distinctive sound, but you have to admit the modern engines are more efficient.

[@TheRealREDracing]

I had the pleasure of seeing a 737-200 in person C-FFAL as part of an exposition. These engines are very impressive with the gravel kits

[@StigAviation]

I think they’re still flying them up in northern Canada. Nolion air I think 🤔

[@hightechcarpentry]

You are 100% right about how loud these engines are. IFL Group still owns 3 727s and they fly them in and out of a small airport near me. I live 12 miles away out in the country where it's very quiet. I can hear them takeoff from here and know it's one of their 727s. When I lived much closer to that airport, the 727s would literally make the house vibrate and the windows rattle.

[@StigAviation]

They are incredibly loud, if I remember correctly back when they used to fly in and out of LAX, they would have a noise ordinance restriction. They wouldn’t allow them to fly past 11 PM.

I LOVE the JT8D. Sadly we don’t get to see them on many jets in the U.K. We did have an oil spill response 727 based at EMA for a short time (G-OSRA) which had the Valsan JT8D-217C engine. I love the sound of these things! Lovely workhorse of a power plant. Great video, Stig! Very informative and educational.👌🏻

[@Aleksandar6ix]

I am fortunate enough to have had the chance to fly an old DC9 with Northwest Airlines. Leaving Detroit for Buffalo, we did a power back from the gate! It initially startled me a bit, as we rolled forward before actually moving in reverse. What an experience! Oldest airliners I've been on were a DC8, L1011 TriStar, and 747-300 (-200SUD).

[@StigAviation]

That’s absolutely incredible that you got to experience that.

[@av8tore71]

During summer break from law school I ran a CNC at Woodward Governor drilling shaving on fuel control units for the GE, Pratt and Whitney & CFM. It was a lot of fun and since I already had my A&P IA endorsement I got to follow a unit I started from start to finish at PW

[@StigAviation]

Isn’t it amazing to follow through and see the fruits of your labor, also quite interesting career field you have. Your lawyer and and a airplane Mechanic, that’s quite amazing.

[@edschoenstein1893]

Great show! I was on an American MD-80 at DFW sometime in the mid-2000s and we did a reverse thrust pushback from the gate!

[@StigAviation]

It was very rare they did that, but when they did do it it was an incredible thing to watch.

Incredible amount of power, just out of curiosity did you board the aircraft through the front or the aft air stairs. ?

[@boomer9900]

I sat in the last row once on a MD80 flying across the country. I was nearly deaf when I landed. There was a low frequency growl.

I worked on the assembly floor at P&WA in Middletown, Ct for a few years in the late 1970s. We were building a JT-8 everyday and JT-9s every 3 days. Many of the engines went to customers in Alaska and i probably flew on planes with engines I helped assemble because I moved to Alaska and flew on jets with JT-8s a couple times a month commuting to work.

[@StigAviation]

Wow, that’s amazing. You were a part of a very important chapter in aviation.

[@fxhomie1]

Thanks for the informative video. I just got a 1:200 United Airlines 737-100 "737 Friend Ship" livery that has the JT8D engines. The detail on this plane is fantastic so I did some research and found out the combustion chamber is 9 stage can-annular, rather than the annular chambers on modern engines. It shares a common ring like the annual type but has nine discreet combustion zones, each having separate liners and fuel injectors.

[@StigAviation]

Can annular means the same as 9 annular my friend. It means the same thing. The combination chamber is one thing that never changed in the JT8D

[@viscount757]

[@richardlewis4288]

Yes you’re correct the heat exchanger up front is the CSD oil heat exchanger. But most aircraft had it removed from that location and put inside the fan bypass duct so whenever the engine is running a stream of fan air is cooling it. When it’s up front like that engine has it cooling air is from the aircraft moving through the air. When the aircraft is on the ground not moving or very slowly there is an educator system that used 13th stage air to induce (draw, suck) cooling air through the heat exchanger.

My favorite engine next to the GE90. Most of my flights in New Zealand as a child to late teens were on Air New Zealand's 737-200s. I always liked the landing and watching the reversers activate after touchdown. They were fitted with Nordam hush-kits to reduce engine noise especially when flying into places like Wellington or Queenstown.

[@StigAviation]

And a very interesting and very loud engine even with the hush kits.

[@ThunderboltDragon]

@ 16:47, the Saab Viggen which you showed a photo of in the video had thrust reversers and could technically pocket park itself. Not sure if this was ever used, but possible when deployed (during exercises) to dispersed operation road bases. The Swedish military designation of the JT8D is Volvo RM8 which was license manufactured by Svenska Flygmotor (which later became Volvo Aero) in Trollhättan. As for the Viggen itself, only two remain in airworthy conditions and both are with Swedish Air Force Historic Flight which is an association dedicated to preserve historic Swedish air force aircrafts in airworthy condition and to fly them. Viggen take off and landning performance is about 400 meters for take off and 300 / (just below) 1000 feet for landning.

[@StigAviation]

That’s very interesting, I did not know it had a thrust reverser.

[@michaelchan8915]

Excellent and informative video!!! I had thought that I heard of thrust reversers being used to back the aircrafts from the gates at one time. Can't remember where I heard that, but always thought it to be unsafe for obvious reasons. I'm quite certain there must be a safe distance that grounds crews must maintain from either running or starting engines.

[@StigAviation]

It’s definitely not allowed to do nowadays, but in the past they used to do it quite often.

It is a giant engine for a jet fighter, one can almost have a banquet in the engine tunnel of the Viggen when the engine is gone 🥳 Edit: Yes, Viggen has thrust reverse too, convenient for parallel parking 😉

[@StigAviation]

I did not know it had a thrust reverser that’s actually really cool. Thank you for teaching me something new.

[@zapfanzapfan]

@@StigAviation You can see it in action at air shows. There is one vintage Viggen flying that I know of.

707, DC-8, 737, 727, DC-9, MD-80's, among others. Low bypass, loud, up to 21,000lbs thrust, water injection used in early days for more thrust.

[@StigAviation]

The thick black smoke out the tail was a dead giveaway if it was water injected. And you can smell it for MILES 🤣🤣

[@publicmail2]

@@StigAviation Yes used to think it was unburnt fuel, but just water, alcohol as antifreeze, and some oil for anti corrosion.

[@ScottPuopolo]

KC-135 used that water injection, correct?

[@publicmail2]

@@ScottPuopolo Yes however the 135 used different engines over the years.

[@TyrannoJoris_Rex]

707 and DC-8 were JT3D

[@Pooneil1984]

I recall being in a jet at a small airport the used reverse thrust to back out.

[@StigAviation]

It’s always incredible to see an airplane do that. But they don’t do that nowadays, it’s a dangerous maneuver

Hello dear friend: U knew right from the beginning that you were "transmitting" from our beloved School. Thank you so very much as usual.

[@StigAviation]

It’s an absolutely great school. Always a pleasure to visit

So you got to work on the MD-80s then, What was that like compared to the newer jets you work on today? Please do more on this id love to see your take on it!

[@StigAviation]

@@nuherbleath461 me 80 was a very simply but not mechanically friendly aircraft. Compared to modern aircraft is like comparing a hammer to a cell phone.

@@StigAviationthank you for answering, means a lot :) also good analogy

JT8. "D". Started life as a 13,000 thrust class low bypass engine.-9, -15 & -17R kicked that up from 14K to 17,500K in the -17R motor-that engine also introduced APR-Automatic Power Reserve-which detected a differential of thrust between the engines & when triggered provided an additional 500lb. of poop automatically to the "good" engine. Then the -200 series-larger fan & more sound proofing as well as more power-one additional LP compressor stage as well. The -217C/219 engines were quite unique-if the engine had had incorporated some specific Pratt SB's at overhaul-all one had to do was pull trim data for either a 217C or 219-and trim the engine to which ever power level the operator wished for. Then-once completed-the tech simply flipped the engine data tag to reflect the trim status on the engine.
