And why is it the Pratt & Whitney J58 ?

Just look at this masterpiece. An engineering wet dream.

The J58 is a cool engine and its very clever, but frankly its the GE-90. The big fan high bypass engines changed air travel and the next gen 9X is just so insanely powerful. 128,000 lbs of thrust!  To put that into perspective it would take 4 J58's in full afterburn to outthrust a single GE-9X

runner up, PW f100

Racing engine for 1937/38 “ Speed Spitfire ” world speed record attempt. Merlin III with strengthened pistons, connecting rods, and gudgeon-pins, running on increased octane fuel, developed 2,160-horsepower (1,610 kW) at 3,200 rpm and +27 lb boost, a power/weight ratio of 0.621 lb per horsepower. Completed 15 hour endurance run at 1,800-horsepower (1,342 kW), 3,200 rpm at +22 lb boost. [20]

27 pounds of boost?!

That’s the best aircraft piston engine ever made. I’ll agree 110%

I edited my comment. As for the F100, it was a revolutionary engine in terms of reliability, digital throttle control and versatility .

Here’s another one: the engine for the 1903 Wright Flyer. With no suitable engine that was light enough for the Flyer, the Wrights gave basic drawings of the engine to their mechanic, Charlie Taylor, and he built it from scratch in six weeks. The Wrights needed at least 8hp to get flying, and Taylor’s 152-poun d engine provided 12hp.

Because it powered my favorite and some of the most iconic early Learjets, provided 2,850 lb f (12.7 kN) of thrust, and because it is a proper turbojet. None of this modern turbofan BS!

Plus look at it, it is a beautiful piece of engineering.

No argument from me. But # 2 is the Kuznetsov NK- 12. Most powerful turboprop ever . Just   listen to the ridiculous noise.

Is that the Electra/Herk engine? I’d have to agree.

Do you know the story about the P3 that ditched in the Atlantic? There’s a great book about it.

It is. I spent a few years doing tear-down and build-up on them, a couple of years running engines and props across the test cell, and a few years maintaining engines on AC-130Us. To say I have a soft spot for them is an understatement.

I have not heard that story- I’ma have to look it up!

The SR-71 connection and the whole semi-ram jet thing is pretty awesome, but for pure wh ack tastic- awesome I gotta go with the Napier Nomad. I mean turbo-compound H-12 d iesel over-complexity (with astounding thermal efficiency) For The Win!

I was going to nominate the Rolls - Snecma Olympus 593 or the Kuznetsov NK32...but yeah, the J58 is pretty phenomenal.

The F-onehunnert is a good one. I can say first hand that it is one reliable mother, and super easy to work on.

By the last round of cylinders, I wonder how much cooling there really was...

“The four row configuration had severe thermal issues that decreased reliability, with an intensive maintenance regime involving frequent replacement of cylinders required as a result. Large cooling flaps were required, which decreased aerodynamic efficiency, putting extra demands on engine power when cooling needs were greatest.”  

https://en.wikipedia.org/wiki/Pratt_%26_Whitney_R-4360_Wasp_Major

it was a nightmare, If I recall flight journal had a photo showing a cart with a mound of old spark plugs that would have to be changed every mission.

You know what would be better than a P&W J58?

An   electronically   double fuel injected FADEC P&W J58 that can run on JP8 .

The SR-71 had a f ull mechanical low-pressure high-flow JP7 system that makes Bosch Jetronic look positively space-age by comparison. Afterburner is basically just a high lift pump dumping fuel straight into fire path.

I’ve got to go with the Rolls Royce Snecma 593.

I mean, four of them propelled a supersonic passenger aircraft.

and, they used a Vulcan for testing.

There was a fantastic special (think maybe 10 years ago) on PBS about a group recreating their 1906 and it was terrifying the pilot. “is this going to explode next to me?!?!?!”
