- High speed (64 fps) camera view of a Titan engine test on June 17, 1964, here presented at real speed. Sound is reconstructed from a Titan II launch and a water sound suppression system test. The LR-87 engine motors can be seen gimballing.

=========================================
The LR87 was an American liquid-propellant rocket engine used on the first stages of Titan intercontinental ballistic missiles and launch vehicles. Composed of twin motors with separate combustion chambers and turbopump machinery, it is considered a single unit. The LR87 first flew in 1959.

Say what you will, but those hypergolic fumes sure burn a beautiful blue!
As a kid watching Gemini launches live that is one of the things I loved! The Titan II just one of my favorites!
Hey Calvin

Well, they actually burned with a transparent, very pale, yellow flame. In other engines it burns with a pale, pinkish flame. It has to do with the fuel-to-oxidizer mixture ratio.
They always looked like shock absorbers.
best engine ever
That’s some really fast gimbaling
I love the smell of nitrogen tetroxide in the morning.
I'm a Aerozine 50 man myself, but I wont judge.
It's kind of a sharp sweet tang, whereas A50, MMH, and UDMH smell like clover. If you smell it, you've been overexposed. Move crosswind before your foreman has you doing paperwork and sends you to the company doctor so they can cover their ass from a lawsuit. :D
Amazing what they did way back then.
They do engine tests today. SLS did something quite similar not too long ago!
We've been in the future for awhile now.
Starter cartridge sound begins at 0:09. "The cartridge was a solid propellant and burned approximately 1 second, producing approximately 2000 psia to the TPA turbines." I've never been able to find an image of one of those. Anyone?
It's one of the can-shaped items hanging between the engine, but the image isn't clear enough to tell exactly which one sadly. If they're anything like the UK gas generators for Vulcan's it's literally just a dumpy can filled with pyro material. Cool way of starting a turbine though!
@@bravodelta3083 even the b52s used those shotgun type pellets
No, the cameras were only turned on after touchdown.
@@sidv4615 No, the gas generator on LR-87 is a large can, not a small start cart. It's initiated with a small tube shaped initiator filled with alcloa pellets.
The gas generator is a large can, usually painted a sort of beige-brown color, about 16 inches long and about 14 inches in diameter. It's not much to look at. It sits up by the turbopumps. I used to test those, and both before and after I worked on testing LR-87 and 97 engines.
We had some great names for our rockets!
Excellent work and footage but aww, no *BOO-eee-OOP!* turbine startup sound :)
There's a hint of it in the dubbed sound taken from a launch. Many launch videos don't have it for some reason.
Sound was taken from a period Titan launch. Most of those recording were taken from a distance so I guess that's why the BOOP is low. I'm aware that up close such engine noises should be louder than the BRUUMMM! But I'm limited by the available recordings....
I'd say it's because it was recorded from distance, and at lower levels because of the loud volume as the rocket ascends. It's possible to mix sources, but that can be misleading unless you have a good accurate master recording to go by.... As far as I know such recordings exist only for Saturn V and the Shuttle.
I got a nitric oxide burn of my sinuses once. Two weeks of sleeping with a vaporizer and blowing bloody boogers all day and night. No fun.
Love that red fuming nitric acid leak on the right hand engine side!
I thought that was N2O4 ?
That's N2O4, and its Ox-rich exhaust from the turbopump, not a leak.
@@saundby Respectfully disagree - Turbopump exhaust is straight down between the two combustion chambers, not in the direction you can see the visible N2O4. #16 in diagram below:

You mean sped up. High speed footage would be slow motion
POV: when you want more fuel tanks in sfs😂
Amazing video!
This is awesome !! 👍🏻👍🏻👍🏻👍🏻
At 2x speed, you can sorta hear the Titan whoop at startup.
Only liquid hydrogen and liquid oxygen have a higher specific impulse greater than red fuming nitric acid (nitrogen tetroxide) and hydrazine.
Uh, no. Even at this early stage, there were RO-1/LOX engines with Isps well over 300 seconds, compared with the LR-87’s 290.
@@the18thdoctor3 We managed to get over 320s with later pump-fed engines at Aerojet, and increase the efficiency of the LR-87 and 97 through their lifetime, though it was the upper stages where we really put our effort as atmosphere and gravity losses are enough that pushing efficiency on the Titan engines didn't pay off. Transtage, Transtar, XLR-132 and XLR-134 got the attention to Isp. XLR-134 set a storable Isp record that stands to this day, as well as longest firing of a storable engine.
I love the chemically dirty look of Titan 2 engines.
Hello
Ladies and gentlemen, the launch of the James Webb Space Telescope is scheduled for December 22nd at 7:20am EST from French Guiana on top of the Ariane 5 rocket.
I believe that the engines used on the Titan II were later used in the Titan III, Titan 34D, and Titan IV.
Are you sure you got permission from your parents first?
Yes, uprated versions of these were used on Titan IV with some design changes. The Titan III versions (including 34D) were pretty much the same engine. The Gemini versions (which these are, this test looks like it's on stand E-1 rather than G-3) had modifications for being man rated.
Bwoop!
Thank You for this post !! awesome LR87
Someone knows why the engines move? That it helps to redirect the rocket?
To test gimbals/system itself? No use of them in such test and not trsl flight.
@@override7486 ahhh. Thanks. Maybe they move cos of the power. Maybe is like a vibration
@@override7486 yea I think this is a gimbal test too. The duration of the test was very short, and the gimbal movement of each nozzle was very well-synchronize
It's a gimbal test. Similar motions will guide the rocket in flight. Here they simply following a test pattern (to/from the camera, left/right from the camera, etc).
They are not following a flight profile, just testing the full(?) gimbal range between both engines. See how they move mirroring to each other at times.
0:09 turbopump sound
Agent orange ... 🔥
Yes, that orange stuff is nasty!
N204 turns into nitric acid when it connects with water, like in your lungs. The effects are bad, but very different from those of agent orange, which has biological effects that can be very subtle and last for decades. N2O4 does all its damage right away, then is neutralized with no long term biological effects other than the damage it does to tissues. Don't breath it, and if your skin gets exposed, jump in a safety shower and keep it running for a long time.
At least it doesn't have the high surface tensions of the hydrazine compounds, which sink into your skin and burn deeply, as well has having long term effects on the liver, and in the case of UDMH long term biological effects increasing the chances of cancer.
All that orange, by the way, probably represents about a half a cup of N2O4 or less. A little makes a lot of cloud.
@@saundbyAppreciate all of your insights!
