These are called "clamshell" reversers For obvious reasons haha Commercial jets seem to.be drifting towards "cascading" reversers. Which open up more inside the engine than outside No fun
Hated those clamshells when I an apprentice. The DC9/MD80, were fitted with the same basic engine and T/R. As good as guillotines we were told when young lads.

What are those clamper things at the back of the engines??.. Iam only begging to get interested in planes.. I have never seen this on a plane so Iam curious.. Please help explain it to me in basic terms
Those clamper things are called thrust reversers..when they are deployed they direct the engine exhaust forward and help slow down the aircraft. With the main Landing gear brakes and engine thrust reverses the aircraft is slowed down to taxi speed. The clamper things are called clamshells, upper and lower, they are hydraulically actuated from the cockpit.
@@mikecovell3629 .. aarrr thank for taking the time to reply to my question I done some googling for research and got the jist of it ..and your absolutely on point thank you 👌
The 737-232 was my first Captain assignment with Delta. It was fun and easy to fly although a bit slow at cruise. It was much more modestly powered than the 75/76 I had just left. It was a good bit more busy in the cockpit without an FMS. It was like the old 727 days- spinning the course knob and double checking the Jepps each segment. Many takeoffs, even from the long runways at ATL on flights to IAH required full power. EGT's were right at the red-line until thrust reduction at 1,000'AGL. I must say that for passengers seated behind the wing, the reverse thrust operation was the most visible and dramatic (as was the noise on take-off).
Billy, these parts of the plane were sent to the Aviation Technology Center in Indianapolis as an instructional aid, rather than recycled into aluminum cans.
omg same, i was 11, it was my first flight ever. US Airways metrojet. I watched the spoilers deploy and the reversers open, i'm told i turned pale cuz i thought the plane was being ripped open by windshear. Good times good times.
Poots Muhgoots, the 737-100 and 200 series had no bypass air like other turbine jet engines. 100% of the air taken in, was used in the hot exhaust output of the engine.
@@CapStar362 i know that. I was just commenting on that very solid noise the reverse thrusters made when they deployed. They deploy with such authority. Thought it was cool.
That shrill noise is from an external hydraulic unit necessary to operate flaps and thrust reversers without engines or APU (see its hose extending from left to right under the left wing).
That noise is the hydraulic pump operating. Mechanics usually don't operate the APU inside the hangar for safety reasons. Plus all airlines usually have the "NO APU and NO ENGINE operations inside the hangar" rule.
When I was much younger, I remember flying on the 200's. I didn't know one series from the other at the time but I clearly remember the reverse thrusts deploying in this odd way and being fascinated by it. Fun to see the mechanics of it up close, thanks for the post.
i was an A&P for several years at Continentals heavy check [C&D] at Denvers old Stapleton airport.The thrust reversers work like a clamshell rotating inwards diverting the thrust forward.They work in conjunction with the forward,mid,trailing edge flaps and speed brakes [spoilers][rectangular panel] on top of wing to slow the plane.
I flew on both the -200 and -300 with Southwest and its like night and day. You knew when the JT-8D's fired up, that roar just permeates you. And you heard it on the ground before you saw the plane. It was a no nonsense engine, when you commanded full throttle, it gave you that and 10 cents more. And the lounge over the wing, yess! Always room in a -200 to stretch out, I made beeline for that seat and claimed that spot as my turf, dammit! When that door shut, I propped my feet on the opposing seat, tipped my hat down and zzzzzzed all the way to HOU from CRP, a nice 40 minute snooze.
Oh the memories of being a kid on Aloha Airlines' flights between Honolulu and Hilo. I always wanted to sit just behind the trailing edge so that I can watch the mechanical symphony.
Loved the old -200. Both B system pumps were electrical and you could run the A system through the Ground Interconnect. Made function testing quick and easy. The Classics and NGs had completely separate A and B systems with only one electric pump each... so things went much slower unless the engines were turning the engine driven pumps or you had a ground cart. Spoilers and thrust reversers were always locked into the open positions with physical locks to prevent accidents. The last one I worked on was Alaska Airlines -200 Combi over ten years ago. They were really rough... being used for gravel ops and very high cycle machines with lap joints and lots of patches.
No less than Herb Kelleher of Southwest Airlines might have lost his head in similar circumstances. He once poked his head into the back of a 737 engine, only to have a mechanic unceremoniously haul him out and give him a cram course on Reversers 101. Of course SWA was and is noted for its all-737 fleet.
The old 737-200 series with the pneumatic reversers. Pretty to look at and a pain to work on. I don’t miss working on this plane and the 727-200 , both with the JT8D’s on them. A real work horse for Boeing.
I wish my A&P school had a 737. Biggest plane we had was a King Air, and the biggest engines we had were two or three T53s from Chinook helicopters donated from CCAD.
We had a 727, in fact United's first or second of the model. No engines as UAL owned their power plants and had full remanufacturing facilities in san francisco for them. Was all decked out in its early 80's bright livery. Really neat old plane, served UAL since 64 or so.
I have a work accident in a finger and everytime i see these things I think about that day kkkk but the accident was in truck repair :) sorry for my english i am brazilian!
The original TR opened straight up and down til late 69. They found that the exhaust was lifting the aircraft, so they retrofitted the diagonal opening type, and on all new ones from then on. This was also the time of significant vortex generator changes = Fewer, bigger, and gained 6 kts cruise. I was there.
love those low bypass old style jet engines. They look so sleek and sporty on the nice ol' 737. The new ones with those high bypass turbofans and the huge nacelle look so dopey.
You are completely incorrect. Modern jets get most of their thrust form the 'bypass air'. In fact, about 75%-90% or more of their thrust comes from the 'fans and not the core. The core is basically meant to run the fans in modern jets.
These engines are low-bypass, so there is no way you could use bypassed air for reverse. In high-bypass engines there is more bypassed air than not-bypassed, so it makes sense to use bypass air for reverse.
The sound of the reversers when they hit together is amazingly..great video

be sure to keep enough distance from those reverse thrusts if it's powerful enough to stop a 52.000 kg plane, it can press a person easily in half.

Now that is vintage.
I have fond memories of those buckets. 😂
I saw on another plane reverse thruster video that they had to be discontinued as they dangerously blew debris back into the engine.
I'm always wondering if that thrust reverser is actually a reverser or are they just a bigger drag-inducing speedbrake that also blocks the flow of hot air from the engine from pushing backwards instead it forces it to the sides....
They do Infact reverse the thrust, although it's not very efficient. They get the job done though.

ptroinks Sadly the new ones didnt like that
Yep I miss those airplanes...I too loved watching those clamshells in action😊
First time I saw them while watching thru the window just next to them during landing I freaked out until I realized what was happening.
I think that freak out occurred more with the 727 wing. That wing, looked like it fell part when all its stuff was hanging out there.

these thrust reversers are allot more effecient then the current ones, because they redirect the complete airflow and not only the bypass air.
The bypass creates 90% of the thrust lol plus what Mind said.
Not just that, they also act as parachutes.
You are completely incorrect. Modern jets get most of their thrust form the 'bypass air'. In fact, about 75%-90% or more of their thrust comes from the 'fans and not the core. The core is basically meant to run the fans in modern jets.
These engines are low-bypass, so there is no way you could use bypassed air for reverse. In high-bypass engines there is more bypassed air than not-bypassed, so it makes sense to use bypass air for reverse.
