SR-71 J58 Engine Tour 

Alex your grandfather is a true HERO!!! Not to mention one great pilot and keeper of secrets.

Reallly???? You have one heck of a super cool grandfather there. He truly is a part of history then.

@@markp.9707 hero? That too much

U got to be proud of ur grandpa! He's a walking hero! WoW so much love and blessing to u and to ur grandpa

Tell him thank you and I love him in Christ. Love

BluntForceTrauma666 How, dare you! exercise, prudence and good judgment!

@"Sir": Right, right...because you know me OH so well. Now before you do anything else, go put a little dab of Vagasil on that puffy, nasty gash of yours and get back to playing with the brown rocks from the litter box. You little stinker, you're kinda cute at times...

I was going to add my own comment, but yours pretty much covers it.

BluntForceTrauma666 well said

If only more people were more like you sir.

Yes so glad i was a very good friend of him at Lockheed and Ben Rich.Many of my design drawings are in his collection, before the SR71 was ever built.Kelly never designed the engine on it.

Yes he was until i came along.

@@davidmyersretiredaerospace8038 Ben did the engine modifications, right?

Ben Rich was a very good friend of mine at Lockheed so was Kelly.Lockheed was so impressed , with my design work when i was 10 years old when i sent them many copies.They give me a top job when i left university.Kelly thought my design work was way out into the future, and much better than the blackbird.Only drawback would be cost production building them at that time.

Lockheed skunk works and Area 51 both sites i worked at.Did some work at Northrop until i was zapped out from there.

As Major Shul told an aspiring pilot, "Become an aviator, not just a pilot." This is probably part of what he meant.

Built by the World's Finest, P& WA,

The nozzle is a masterpiece, not the engine. It only puts out 35k lbs thrust. There are bigger engines. but the nozzle and the bypass that utilizes the shock inside the nacelle and creates 80% of the trust to M3.2.

Yes and no and it was not built by Lockheed.It was a very old design just modified.

I've heard you spend less fuel going full throttle.

By who???.

search for other videos on the engine. He is not explaining it quite right.

Anonymous the total video was a lot longer for the whole aircraft and his experiences flying it.

I wish it was 10x longer

Yes me too

@@UtsavGhosh24 There is a 1 hour 18 minute interview with this guy on this channel. Highly recommend you watch it. It's fantastic.

Now my SR71 is a garden hose

Now my garden is an SR-71 hose

My SR71 hose is a garden now

My 71 garden is now a SR hose.

The rocket-powered North American X-15 is the fastest crewed plane ever made, with its highest recorded speed at Mach 6.7, flown by William J. Knight. The SR-71 is the fastest crewed, air-breathing plane on record.

dont know about that i think they got help from others. these planes was way to far ahead of its time.

pgice yeah ok. It was aliens. Sure

CIA approached Kelly Johnson in 1957. Project was code named Archangel It was conceived By Kelly Johnson & being developed in the Skunk Works as the A-10, then into morphed into the A-12 before Gary Powers was shot down in his U-2 in May 1960. All done with Slide Rules, no computers or CAD... Sticking point was it needed vast amounts of Titanium which the USA had little of. CIA acquired most of it thru Shell Companies that purchased it from USSR !!! It was then designated RS-71 when the chines were added to the leading edge of the nose & fuselage. The President reversed it to SR and no one was going to correct the President... See LockheedMartin Website for the full story

THat and the fact, from the display at the Strategic Air Command Museum in Nebraska, while the airframe was made from Titanium most of the engines were made from more exotic, and hard to work with, Nickel/Cobalt alloy. Hence the dark greenish color. Super high melting point it had.

The design was topped, and in the year the designer Kelly predicted it would be, 2005, yet this design was crushed and men sent (The American Sniper no less) to end the life of the genius who did it { I got better} When asked why he had a code sequence for the planes that began with 2004, he joked, sorta', that he thought that woudl eb the year the design would be replaced. Yet when I studied the A-12 single seater at the JAM at MSP Guard Base, the fastest one ever made, and drew plans for one made of carbon fiber, with H.O.P.E. engines that exhaust pure water and could run into space... Dark Lord Chainey, the Vice-president, Man who stopped the Blackbird program 3 times, sent CIA contractors to cut up our star attraction and take it back to CIA headquarters - long story short - seems it is not only Big Oil Men who do not want US to have a super version of this plane, yet the ED's I call the 'reptile dysfunktion' not wanting Earth Humans to have such weapons - with SOL capability {look it up if you dare}. OH AND for bonus points look up a now often quoted conversation in the office of top German/American rocket scientist Werner Von Braun. When asked about how we got from what were just underpowered box kites to landing on the Moon in just 60 years he pointed to a picture of a silver flying disk and said "We had Help"... really he did. We can still access this "help" form the goodly aleins BUT the bad ones who hold us back go after those who channel this 'genius' and end them.

fluid dynamics.

Sphere723 SO right you are!! Your comment is CORRECT!!!

I've read up on that

That's very interesting. Thank you

Sphere723 , but the air still has to mix with the fuel. You don't just get energy from shooting the air around the engine as that would violate the conservation of energy laws. Not saying your wrong, but there's no way those bits are exposed to Mach air

Mike won’t say you are wrong, but I will. I appreciate this is indeed complicated and I love that people want to understand this engine. The 6 bypass tubes are compressor bleeds used to keep the compressor exit temperature within limits. Normal engines would throttle down or bleed air overboard but at M3.2 you want to take as much air as possible. That means keeping compressor speed up. You then bleed the compressor to drop the pressure rise (temperature rise). The lightbulb moment came in when they said: what if we take the bleed air and put it back in front of the afterburner? This is harder than it sounds but it gets you the max amount of air into the afterburner. Remember, at Mach 3 you are trying to take the high pressure air and just increase its temperature (specific energy) to its maximum. You achieve the highest temperature by burning at the stoichiometric fuel to air ratio. Now, more air means you can add more fuel, which means you have even more energy shooting out the back. The air going around the cowling is there for other reason. Some of it is coming from bleed air around the inlet used to keep the shock wave in place. Some of the air will be there to “vent” the hot engine. And some of that air would be used to help keep the nozzle petals (on the aircraft side) cool enough. The engine does the same with a ceramic liner filled with holes and small opening in the back right before the engine nozzle petals. The aircraft does the same - they send air around the engine and then produce a thin film of cool air just inside the aircraft nozzle petals. The idea that this engine only produces 20% of the thrust is bizarre to me and I would like to check the math on whoever did it. I think maybe they did it in terms of gross thrust instead of net thrust.

@ns2589 thats what expertise will do to you. i agree great video

My dad said everyone had two posters in their room a blackbird and a Lamborghini. Some had a that super model from that 70s show. But I can see how even those who had next to no knowledge of aviation could get excited about learning about this aircraft

I will never lose my fascination with it! Kelly Johnson said it exceeded all expectations! Throughout all recorded history, there are only a few achievements to which such can be claimed,

they're gigantic...

carl you are correct sir

@@neutraIdrop ok. sure, when you're comparing it the largest American airplane.. see it next to other jets and you'll realize how large they are.

@@neutraIdrop yep. quite a bit bigger.

i said the same thing. gonna check it out next time i go.

Those who dislike is a russians

The Ruskies and the Chinese.

Jealous

Because it is too short

Nearly all dislikes on YT are because of big fingers and small phone screens.

Glad you liked it Victor. I still need to read his books. I just love spending time with Rich. He is such a class act.

Have you read his book?

If I remember correctly, Ben Rich won the Collier Trophy for the SR71 propulsion system.

+rav ravensdale Imagine what they have these days

I currently want to build a smaller functional model of the blackbird a single seater then add a few upgrades of my own, including a few items for space

No need. Spy satellites and drones were doing a better job in the 1960s.

Ah yes... the totalitarian government that never seems to be able to do anything... lol.

Gregory Parrott Heat friction was the limiting factor. Engines could take it faster but the airframe and skin couldn’t take any more heat.

No. It was engine limited. The engines were specifically limited to an inlet discharge temperature of 427C which corresponded to Mach 3.3 at 80,000 feet and ISA. This plane had more in common with the Space Shuttle than a typical jet aircraft, with a week of maintenance required between flights. Going above Mach 3.3 would turn it into months as they had to remove the entire outer wing assemblies to change the engines.

@@calvinnickel9995 Interesting. Thanks for the reply.

TheMTrider16 Thanks, glad you liked it

Osymandus Not his link, it’s mine.

In his book, Ben Rich makes the comment that he didn't think aircraft manned aircraft could be designed to go faster than the SR71 because the life support systems could not be designed to keep a human alive. If you think about it, because the average skin temperature of the SR71 is 600F, the crew is basically working inside an oven. On such a hot aircraft, where do you find a cold zone to reject the heat from the cockpit to keep from roasting the crew? I know the X-15 went 4500 mph, Mach 6.7, but that was only a dash that lasted a few minutes. And on that particular flight, they came within a few seconds of losing the aircraft due to structural failure. The SR71 had to cruise for 2 hours at Mach 3.2, which is more than long enough for everything to heat up to thermal equilibrium, then just sit there and bake. Nothing could be used that was readily available. Even the landing gear tires were special. How do you get tires that can withstand 600F without exploding or turning into charcoal briquets? Hydraulic fluid? Special stuff, and mission critical because an hydraulic system was used to position the inlet spikes. Insulation on the electrical cables? The list of problems goes on and on.

Btw, it was Westinghouse Nuclear Power in Pittsburgh that he left. Turbines 😉
