DEEREMEYER1: I've got two of those in my go-kart. It's pretty fast.
newcoyote: If you want to learn more about gas turbine/jet engines, check out
AgentJayZ here on YT. He explains the systems and function jets and
industrial gas turbines very well. Before watching his videos, I thought I
knew a lot about jets. I was wrong. Excellent source if you're into this
kind of thing. Just started with this channel. Also looks very good so
marc fitzhenry: The Blackbird is over rated naturally. Scram Jet is a great design, except
the friction created damages even the toughest materials cannot sustain.
The solution? Stop creating aircraft to fly faster than Mach 4. Leave all
Mach 4 flying to unmanned craft not designed to return in one piece. The
Russians were already aware of this and excepted it for decades until the
sr-71 was finally decommissioned.
MsCordially: oh crap ! what's that orange thing hanging from the rOOf !!?!
Greg exexex: Great! ...... Thank you
TotenKopf42: After watching this and other SR-71 videos - My first thought was - I think
I am in love :)))
Unreal plane - real shame he "had to go" (retirement).
As for dislikes - those people are definitely not USSR descendants - how
can they be if at least 80% of this plane has been made from materials
illegally acquired by CIA from USSR :)
Jonathan Langdale: .
Don G.: PLEASE DON'T FORGET BEN R. RICH! IF IT WASN'T FOR THIS SKUNK WORKS
ENGINEER, JOHNSON COULD NOT MAKE THIS BIRD FLY. HE IS THE ONE THAT INVENTED
THE MOVING SPIKES SO THE ENGINE COULD INJEST THE MASSIVE AMOUNT OF RAM AIR.
FROM THE BOOK "SKUNK WORKS" THAT I PURCHASED AT LOCKHEED IN PALMDALE, CA.
Greg Kundtz: thanks! a great help for a project i'm doing about compressible flow
deadboy600: Two of these puppies sucked up 36,000-44,000Lbs. of go juice per hour! 5-6
pounds each per second!! Hard to comprehend.
John Doe: How can you dislike this?
3 people are descendants of the Soviet Union
Sphere723: These 6 bypass tubes on the J58 are not actually the main bypass used for
the ramjet as some people seem to think. The main bypass is built into the
nacelle itself and sends air completely around the outside of the J58. The
ramjet air is not just skipping a stage in within the J58, it skips the J58
entirely and collects/exhausts behind the J58.
It is hard to show that when the J58 has been removed from the nacelle, but
that is what Rich means when he says this engine is only supply 20% of the
thrust at mach 3. The other 80% is coming from the ramjet "engine" which is
the nacelle itself.
Jim Thompson: Very interesting!!
Thema inproblem: Great video! Thanks for uploading it for us.
jjohnston94: Thanks for putting up all the distracting "subscribe" links every few
Haider A: What an amazing insight. Thank you.
Paulo Feitosa: Thanks, uploader. I have several of his books, when was this?
Michael Millson: mr fitzhenry that is a crappy attitude how fast do you think wed have to go
to build a plane that could renter and leave an atmosphere of another world
this isn't just a chess set that's why they chose the united states to be
the stick in the yard
HybridTheorykid1: As amazing as this thing is - It amazes me to think that they had this
technology back in the 60's! Yet- It still remains unbeaten, 50 years on.
Hats off to Lockheed Martin and Skunk works. I've been in love with this
plane since I was around 12, and I'm 32 now. I saw one of these parked up
in NYC.. What was it, USS Intrepid. I will NEVER forget that moment.
Chan Calvin: Great explanatory!
Filip Talpa: SR-71 J58 Engine Tour
Federico Melotti: .
Magnus Andersen: No flame holders in the afterburner, how do they prevent flameout ? anyone
Ravi Krishna: plane engines - design - people who made it are all legends. I learned
a lot in just 4 mins today
wkeil1981: How do you start this?
euplot: Thaks a lot for all this nice videos!
jared lewis: Aliens
Eric jones: This guy is a pilot so i will give him a break. Those bypass tubes are to
bypass the engine so it can go 'ramjet mode'. Simple.
Peter Senna Tschudin: How many energy does it need to fly at mach 3.2? It depends on how smart
you use the shock waves...
Infidel Atheist: Nice tube bending
Eric jones: Needs to explain Ramjets. not the best explanation but decent.
David Govett: It's always disappointing when magic is explained.
Atomsk12: Didn't they make the inlet electronic or something, so that it was
automatically regulated and help solve some of the unstarts? I think that's
how I heard it on a documentary about the SR-71 once.
basimpsn: How the hell they know to re-used the Shockwave energy as a secondary
engine. more like a RAMJET lol?
Randy White: The kelly Johnson is the best
Corrie Bergeron: He leaves out a bit that needs knowledge of the gas laws from Chem & Phys.
In a shock wave the air decelerates from supersonic to subsonic. Per
Bernoulli, high-speed air (the free-stream) has much lower pressure than
than the low-speed air that's hit the inlet spike and its shock wave, and
(thanks to the spike moving) is INSIDE the inlet. That pressure pushes
against the airframe in all directions. Aft, it goes into the turbine and
bybass tubes. Radially, it balances. Forward, THRUST!
sam phi: The good ol' groidbird!
D Vick: Awesome, I think Kelly Johnson was a alien imo...
ErikJohnston: Glad you liked it.
hornet8833: Great job col.
Guilherme Ruman: Thank you for the excellent video !!!!
tippman2k01: why couldnt my parents have sex in 1977 instead of 87? i want to fly this
xxrailroadxx .: Very nice, thank you very much for uploading.
panda44r: And one last thing about the bypass tubes,.. He seems to not say much about
the bypass tubes, but he goes into describing the inlets more than Kelly
did. Maybe these guys all got together in the O club(s) after long flights
and said "ok, in 30 years, when these monsters are declassified, i'll talk
about the inlets,..you talk about the bypass tubes,..and you just keep your
mouth SHUT!" (the last part was said as Kelly pointed at the lowest ranker,
who was passed-out, pukin' drunk). LMAO! :o)
