Re: Vzpomínka na Challenger a Columbii
V 18 kilometrech ta atmosféra zas tak hustá není, ne? Tady jsou cca parametry, kdy bouchl Challenger
Podle https://www.treking.cz/pocasi/atmosfericky-tlak.htm desetina hustoty

Re: Vzpomínka na Challenger a Columbii
Six pilots have ejected at speeds exceeding 700 knots (1,300 km/h; 810 mph).MilanSpace píše: ↑17.2.2023 14:30 A pro zajímavost - ví někdo, při jaké maximální rychlosti byla provedena katapultace z letadla? A přežil jí pilot?
Díky.
Tady je příběh jednoho. Žádná hitparáda to není, ale přežít se to dá. Při Mach 1. Těžko říct, Challenger letěl 2x rychleji jak píšete vy i Edemski. Ale zase byl mnohem výš, kde je ta atmosféra o dost řidčí...

Re: Vzpomínka na Challenger a Columbii
Z tohohle důvodu dělali pro xb1 celou vystřelovací kapsli, Mach 2 a chlup
Ale, tady jsme výš a kabina by začala zpomalovat
Pokud by měli kyslík, kabina zůstala v jednom kuse a je neomracilo pretizeni, tak by stačilo počkat a šlo by to
Těch kdyby tu je moc

Joe Engle a jeho vzpomínky k vystřelovacím křeslům:
The ejection seats probably were a comfort to a certain extent in the approach and landing tests, because they could be used pretty much anywhere in the profile, even while you were mated to the [Boeing] 747. If there was a problem, if something drastic happened, why, you could bail out at any time. But on Columbia, I don’t know. I guess they were there primarily so if there was a gross malfunction in the guidance system and you entered and came subsonic over the middle of a forested area or a mountainous area and there’s no place to land, you could at least get into a stabilized glide and bail out. But they really didn’t do any good at all on launch, certainly not on orbit.
The idea of the ejection seats, the envelope that they provided you an escape capability was very, very small. They did take up a lot of room and a lot of weight, and they did limit the crew to two people, which, as I mentioned earlier, was a real workload for the crew, a real heavy task load for the crew.
Z toho vyplývá, že s nimi opravdu spíš počítali max během přistání, než samotného startu...

Zajímalo by mě, jestli jsou nějaké zprávy o obnovení programu raketoplánů?
