nah they’re spinning it as “we wanted to burn every drop of fuel in the final stage, we had more than we expected because reasons” the mission was to lose the car in deep space so it’s never seen again and by that metric it’s a success

Just-In-Timeberlake posted:yeah, that's my fave part 99.9% certain it was the other way round, the chines were to help minimise mach tuck and it was only discovered many years later that they gave it a considerably lower radar cross section especially as: nobody had even begun to think about rcs until the 70s, let alone knew how to manage it they knew from observations of the starfighter (but didn't understand why until the 70s) that afterburner plumes give absolutely massive returns on radar the only angle it reduces rcs from is straight-on and pretty much by definition a hostile never gets to see one straight-on

Sagebrush posted:i see your best sr-71 story and raise you the other best sr-71 story those are both extremely excellent stories Sagebrush posted:yeh. the engines were ramjets, which use the aircraft's forward motion to compress the intake charge, so the upper limit on its speed is "the intake cones/wing leading edges/cockpit windows just melted" rather than anything to do with the plane running out of power the main limiting factor is the compression intake temperature if i remember right; assumptions about what that temperature will be as a function of altitude and speed are what determined the top speed limits listed in the operating manual. really the limit was set by what that temperature gauge was showing. anything else could probably take a little melting but engine failure at mach 3.4 would likely be fatal. i don't doubt the rated top speed was broken, maybe even the temperature limit was violated in the process, they probably just had to do an engine teardown and rebuild afterwards to check for/repair any damage afterwards. not something you'd want to do for no good reason, but preferable to losing the vehicle and crew from enemy fire.

Why don't you just put the rocket on a plane and launch it from the sky? Then you're already way close to space. I don't know why people say these NASA guys are so smart if they haven't thought of this yet.

Notorious b.s.d. posted:they spent a lot of time thinking about it, but they did not have the benefit of modern computer modeling in design what im talking about is he said "nobody had even begun to think about rcs until the 70s, let alone knew how to manage it" the convair kingfish was rejected in 1959 in favor of the lockheed project that would become the a-12 and eventually the sr-71. and CIA Project Rainbow had started pretty much as soon as u2 flights started in the mid-50s and they realized the soviet radars could track it, they attempted to reduce the u2 radar cross section and found they couldn't do it with that, thus leading to seeking other planes to be built that would be designed to lower radar cross section (and increase speed) starting around 1957. no matter whether they knew why or how a given thing was reducing the rcs, they took every instance of reduced rcs from a change to heart and tried to replicate it in further revisions of the planes. when the 70s started there was already over 14 years of specifically knowing about and thinking about reducing radar cross section for spy planes in particular, and all military planes in general where possible

Bhodi posted:burning to exhaustion is a very good thing in a thing that's going to be floating through space and that can't be recovered, because while there is fuel there's a potential for additional debris through explosion or mishap, it was deliberate yes but you generally vent the fuel rather than burning to exhaustion, engines tend to be really unpredictable when you can't control the mix and can do all sorts of fun things ranging from "wildly fluctuating thrust" to "oscillations leading to exploding" e: like i said though you might be right, it's possible they did it intentionally this time just because there's no actual payload, but generally if that happens during an actual mission you get internal hearings and investigations and launch delays while people figure out what went wrong Shame Boy fucked around with this message at 02:26 on Feb 8, 2018 |
