but getting ejected out first also means withstanding the force for a longer duration, especially going through the middle troposphere at high speed...I am not sure if that would be easier in terms of survival...
But to increase the chance, in this kind of high speed ejection situation, why not make the escape pod or capsule a standard configuration, in place of an ejection seat...I just feel a well-designed pod or a capsule would provide an extra layer to buffer the extremely strong impact...
And capsule or pod has been deployed on some super-sonic aircraft such as Rockwell B-1 Lancer (still in service at this time)...That might be more expensive and would definitely require much more complicated design and extended experiments...But comparing to human life, all the other costs would seem to me much less important...
I saw this quote from wikipedia,
https://en.wikipedia.org/wiki/Escape_crew_capsule https://en.wikipedia.org/wiki/Escape_crew_capsule
Kelly Johnson, founder of Lockheed Skunk Works, and developer of
the U-2 and SR-71 Blackbird family of spy planes, commented on
escape crew capsules when discussing development of the
YF-12A (Blackbird) ejection seat: ".... I have never been
convinced that a capsule ejection is required for anything other
than high velocity re-entry from outer space...."
But clearly, a shredded suit is nothing like a capsule...
- acveilleux 11y agoIn the SR-71, the pilots wear a pressurized suit that's a lot more solid than a normal flight suit. Incidentally, someone survived ejecting (unknowingly!) from one: http://theaviationist.com/2015/03/17/sr-71-mid-air-disintegration/ http://theaviationist.com/2015/03/17/sr-71-mid-air-disintegr...
- vkou 11y agoGiven that air density at 80,000 feet is ~1/40th of sea level[1], 'ejecting' at Mach 3 there sounds... A lot more survivable then ejecting at 10,000 feet above sea level, doing Mach 1.
