- A short history of the evolution of the Thor-Delta family of rockets from Thor-Able to Delta II.
Models by RaiderNick and Kartoffelkuchen.
Music from the World of Warships OST.
Good evolutionary explanation. I've always admired Thor as a missile and SLV.
Very well done, I would only add Delta III as well as it had Thor based core, but still, great video
Delta III was Thor, but didn't have an upper stage related to Able/Delta, so it's not part of the Delta family. It is part of the Thor family, but in that I also didn't cover Thor-Burner, Thor-Agena, and the Japanese N-I and H-I. I do regret not mentioning the Japanese N-II, which is a Delta 1904.
Wow, what an amazing video Tyler, loved seeing the changes to the Thor remade in ksp
I'm designing a stock delta series of rockets and this video is more helpful than any Google search I did. Thanks!
Those first stage tanks really got to be a mouthful
Well done. As one that was there, 1957-1979, That was the best overview I've seen.
As a young pup, I first heard about the Delta II from a very unusual source. It came from ABC Sports coverage of the PBA Pro Bowlers Tour when they were covering the 1989 Florida Bowlers Journal nearby KSC.
Thanks for this informative Video. I think i'll start a Rocket-Line with boosters in my rp-0 game, to compare cost and ability...
Honestly, they're pretty horrible in terms of lift capacity - the Thor core engine has relatively low ISP for a Kerosene-burning engine. The key to the rocket was always the AJ10, especially once it was able to reignite.
Of that i am shure. Im already way past Thor tech. But at this time i don't use any boosters and just unlocked some Solids...
Very well-made video!
Good job.
Very nice video.
Nice intro
Thanks that was really cool.
I just wish Kerbal would upgrade their rocket exhaust visuals. Some of them literally look like the exhaust is leaking out the nozzle (the early Thor).
Practically none of this is stock KSP visuals, so KSP upgrading stock would be meaningless. There are ways of tweaking that with RealPlume, which is what I'm using here.
Right on, Tyler. Well I can say that the modeling later in the video looked more realistic in the higher altitudes such as at the 10:10 mark.
1989-2018 were the years of service for Delta II
RIP delta we will remember you
One could argue this to be the penultimate American second generation standard rocket; a rocket that was larger in diameter than the 1.65m booster cores on the first generation of rockets (which were directly descended from the German V-2) with new engines, but still needed a very simple, far smaller second stage with storable or solid propellant to reach orbit. The Atlas and Titan did not have that limitation, and thus are arguably third generation, alongside the R-7 (which although still used a Hydrogen Peroxide decomposition startup mechanism, had orbital capability in two stages and employed Kerosene as a fuel instead of Ethanol.
Delta IV would arguably be the world’s first Fourth generation standard rocket, employing a wider core of 5m, being a completely new rocket employing a lighter fuel as a propellant. I’m not sure this is entirely fair however, since Long March 5 has a 5m booster core and Terran R, Neutron and Vulcan all intend to use booster cores with a diameter around 5m. I’m not sure what fuel Neutron uses yet but I’m fairly sure it’s not going to be Kerosene as Beck claimed, and I’m fairly sure he lied about any company actually trying to copy Neutron’s design after Rocket Lab released it.
Just a quite heads up Altair and Grand Central are diffrent Solid Rocket Motors.
I have asked this in an older video but idk of you saw it so... can you do a tutorial on how to install ro in 1.3.1 and rp-1?
I don't know anything about installing RP-1 - I haven't used it myself yet.
@@RaizSpace and what about ro in 1.3.1?
Basically, just go to the official RO thread, get the required mods plus RSS first and test the install (the links all work properly now, I think), and make sure to install mods in small batches - not all at once.
@@RaizSpace thanks!
If there was a 5th Delta, it would fittingly also be called Delta-V
There really should. Unfortunately Vulcan is taking Atlas and Delta out. Why not nickname it that.
IT HAS 9 BOASTERS AND A THOR CORE AND ITS THE TRUE LAST THOR
Can't quite figure out if you are Russian, Finnish, German, or what, but my bet is on the left side. Am I right? =D
None. You seem to have a very limited scope for what I could be.
@@RaizSpace a very creative youtuber? Nice videos!
So the soviets only started doing hot staging after the US had done in flight ignitions with the AJ-10?
That's correct for orbital rockets - I can't verify other systems. The R7 rocket family did not get upper stages until after the AJ-10 first ignited in-flight.
@@RaizSpace Ah cool. I didn't realize that. Thank you
And 8000 series for the delta 3
in 11:46 what delta rocket is it
Delta II, the best of all. I'd say that it's a 792# series.
Mod?
I like delta2
You forgot DELTA 3
Al-tear, not Al-tay-eer.
The way I pronounce it is closer to correct because the name comes from Arabic, though I'm no specialist in that language. The way Westerners tend to pronounce it is incorrect, as with many star names. It's sort of like how NASA people tend to pronounce Gemini wrong.
@@RaizSpace point taken, and you don't see me making these awesome videos, right?
delta III tho... ;-;
I want to like this, but it has 69 likes, so, sorry tyler
you can like it now lmao
Twu patato
NII = off brand Delta II
skinny second stages bad
#deltaII #icesat2
second
First!
