Insane Aircraft Engines Sound That Will Shake Your Soul ▶ 1 🥶😱

[@donallen7990]

I worked on the R1300, R-200 and the R-4360 when I was in the Air Force back in '62-'66. LOVED MY JOB!!

[@misters2837]

The R1300 never sounds "Right" to me, I remember hearing them in T28's at air shows....I am always thinking....Dead Mag? - LOL!

[@markc4768]

@@misters2837 I've got about 1200 hours in the T-28B and C as a test and cross country flight mech/E2P in VT-2, VT-6 and NARF Pensacola for 3 years in the late 60s. After volunteering with a group that rebuilt an 1820-86A for a resurrected B back in 2014, I got a ride in the finished bird with a retired navy pilot who had been an instructor at Whiting Field when I was there. I noticed a big difference in exhaust sound from what I remembered from the 60s - that smooth, almost deafening note at 52inHg was missing - still had good power though. I assume it came from the differences in new and old fuels - green 100/130 alkylate vs the original 1940s era leaded 115/140 purple that went away about 30 years ago and has only recently made a comeback. When supercharger HIGH was selected at 15,000 feet while climbing at a pretty good rate, it didn't give the same kick in the pants that I remembered, either. The old bird (whose every switch, lever, and gauge I can still visualize in total darkness) remains an impressive machine and needs no excuses in the presence of it's elder warbird brothers....

[@DavidParker-cf2km]

@@misters2837 Yes, the 9 cylinder radial engines with their 5/4 exhaust always sounded like they were missing on a cylinder. Only the high power runup rpm test knows for sure! But, the T-28Bs and T-28Cs that I flew in 1971 in VT-6 were equipped with the R-1820. The S-2C, C-1A, and Hu-16D were also equipped with the R-1820. Never heard of a R-1300. That must be the 7 cylinder engine in the T-28A that the Air Force flew.

@donallen, thank you for your service during the not so cold Cold War. We were at or near SAC bases which had the B-36, C-124, KC-97 and KB-50. I remember that sound at takeoff, the drone when they flew high above us and the dishes rattling in the cabinets.

Hearing the engines firing up and running was always the best part of the airshows I used to go to.

[@BW12149]

The P&W Wasp 18 cylinder engines were the marvel of design and engineering, and have such a great sound.

[@JViello]

They were built about 5 miles from me in the East Hartford, CT "Headquarters" plant. What a campus they have/had over there. 600 acres I think, with their own airfield and buildings that go on and on. At the peak in the 80's that plant alone employed 60,000 people! (And they had several plants around the state!) Now, it's a sorry shadow of itself. Maybe 3500 people there, and only one other plant still going with a skeleton crew. Don't forget the SR71 Blackbird would not be what it was/is without Pratt solving the problem and coming up with a turbo/ram jet hybrid engine! Pure genius! Official speed of Mach 3.2 but reports from pilots getting close to 4 with plenty of throttle left, at 80,000+ feet! It was the fuselage that couldn't handle the heat from the airspeed, not the engines holding it back! I listened to one story from pilot Brian Shule (sp?) who had to outrun a SAM shot at him (Process that for a second. LOL ) and throttled up, limits be damned...he said he tried to touch the canopy afterwards and couldn't because it was too hot...with gloves on!!

[@davelowets]

[@brianthesnail3815]

Some years ago, I was working in my garden here in England on a quiet weekend summer day. Then I heard a propeller driven plane in the sky and I just 'knew' it was a Spitfire from the sound of the engine. Flying alone either to or from an airshow. I had never heard one in real life before, but the sound was magical. It sent a shiver down my spine. It made me spin round and stand open mouthed looking up. I am not prone to hyperbole or a lot of emotion but I will never forget that sound.

My soul has been shaken. The early radials are so insane...think of them as the "out of the box" ultimate engineering design. I mean who who thought to do this? And it was like early 1900s....

[@ronjon7942]

I still can’t believe radials came AFTER rotary engines..at least insofar as widespread usage. The 985 to me is the Chevy 350 of radials, and prolly my favorite, even after working on larger ones. It was the first I maintained, on a Beech 18. Perfect engine on a perfect plane. Oh wow, the 4360 sounded silky smooth and quiet at the first view from the front. I’ve a better appreciation for the 680 now than when I did when I worked on one, as I didn’t particularly care for the Stinson it was bolted on to. Geez, the Griffon sounds like silk. The Merlin was great, but I always thought it sounded like a zipper. The Griffon is, wow, amazing. The 1710 is a favorite. Such an underrated, under developed American masterpiece. If only the USAAC wouldn’t have told Allison not to bother developing superchargers.

[@mixter7x7]

If you listen - these engines don't like to idle. They lope in idle and run smoothly with throttle on. It's because their cam profile is that of a street rod / drag car. These engines are made to cruise continuously at 75%.

[@davelowets]

They're made to cruise at a steady 2500rpms or so. They change the pitch of the prop to keep the engine at a steady RPM while applying more power if they need to.

The RR Griffon is a different engine to the Merlin which powered most Spitfires. The Griffon didn’t go into the Spitfire till about the Mk 24 which was nearly a different plane to the Spitfire. Also the US had trouble building aero engines big enough to be useful early on which is why the Merlin built under licence to RR was put into the Mustang. That is what made the Mustang the power house it turned out to be.

As someone that was done quite a bit of work on P&W 1830's, it saddens me to see the air-cooled radials ran without some method of cooling them, as is the case with that R-3350 pulling power. Those back cylinders get hot very quickly without proper airflow. They won't last very long like that, and it's a shame to see them deliberately abused.

[@vumba1331]

Rotating the cylinders helped to cool them when they were on the ground hence they were able to get some good power from it without the engine overheating. Manufacturing air cooled cylinders with effective and efficient cooling fins was still quite a challenge at this time, a side effect as you say was the gyro effect on take off and in turns when flying. The other side efdect was that they were 2 strokes that used castor oil for lubrication, after flying a couple of hours ingesting those fumes you were cleaned in your bowels when you landed!

I love most engines, respect them, props- kind of scare me, but the power! Electric motors are great as well and the Diesel-electric, etc., it's amazing what we can do when we put our heads to use for something good! Classic Cars and Boat Engines get that, the power to move bug ships OMG! It's all just amazing to me.

Fire up a radial engine in front of your house ? You can be my neighbor ! That’s gotta be a interesting oil system w/the cylinders rotating

[@hopelessnerd6677]

I can't see how lubrication would ever work. Sure, the pistons are stationary, but how do you keep all the oil from eventually ending up in the valve covers?

[@Stevie-P123]

Oil is in the fuel and enters the crankcase first , bit like a simple two-stroke , it travels through a port valve in the piston itself and is eventually spat out the exhaust valve at the top of the cylinder. They are still a four-stroke but the mixture in the crankcase is excessively rich so additional air is actually drawn back in through the exhaust valve before the compression stroke.

They used castor oil (ricinus) and fuel mixture for lubricant

@@glbor yea and in some cases it give the pilots the squits. 😏

@@glbor well, it worked great in model engines.
