The SR71 was developed through the sixties , it’s 50 odd years old and still looks futuristic., amazing .
@KuraIthys 3 роки тому
More than anything else, aircraft designs are dictated by pure physics, not anyone's ideas about what stuff should look like. The faster it goes, the more you have to bow down to the laws of physics. Concorde also looks exceptionally futuristic. And it's solving basically the same problem as the SR-71 (high speed, high altitude flight), but with a focus on efficiency rather than raw speed.

Please make sure you understand the difference between scientists and engineers. Scientists extend a specific body of knowledge while engineers utilize the existing body of knowledge for the benefit of mankind. Licensed Professional Engineers have a singular duty to protect and enhance the safety and welfare of the public. If a plane crashes or building collapses the engineer is held accountable. Scientists are not held accountable for anything.

@@calidude1114 In cutting edge fields there is increasingly an overlap. An airplane company may discover a new alloy and engineer around it. Similarly a scientist must often have some engineering background to set up a good experiment. Also the engineer is only held accountable if it is his fault.

@@hazza2247 What he says does make sense. lets say this is done in a perfect vacuum with no large gravity generators nearby (like a planet). Motion/speed is relative, a bullet fired from a point in space at a target has a speed relative to the point of origin (a) and the target (b). Now, given a rather short distance between (a) and (b) the speed of the bullet would be measured the same by both parties from beginning to end, with (b) eventually being struck by the bullet. As we increase the distance between (a) and (b), a different force comes into play called 'Dark energy' this is the phenomenon that causes space to expand, the more space there is between 2 objects, the more dark energy expands that space. Therefore, given enough space between the bullet and (b), the speed of the bullet as measured by (b) will decrease until it reads 0 m/s and begins getting farther away until it appears as if the bullet has begun accelerating in the opposite direction. Similarly, the speed of the bullet as measured by (a) will increase. As it approaches the speed of light it will begin to "redshift" and as space can expand faster than light, neither (a) nor (b) will eventually be able to measure the bullet at all. Space has effectively 'stopped' the bullet.

Imagine where we would be if the library of Alexandria hadn’t been burnt, refuting generations of knowledge, hell imagine if the militaries budget would be spent on science instead of bloodshed. We could overcome war and violence while simultaneously both eradicating disease and learning to understand the inner workings of the universe.

The pressure is more about shape than material and submarines actually don't go all that deep.

The thickness is more so decided by buoyancy and the ability to withstand collisions with objects like whales or boats.

@@calvinnickel9995 I'm pretty sure they did do overflights of the USSR. They were so fast that standard evasive maneuvers when a SAM was fired was just to accelerate and outrun it. The Soviets eventually came up with the MIG FoxBat that in theory could catch an SR-71, but they had to burn up their engines to do it. After reaching the intercept speed *once* it needed totally new engines.

Really brilliant. I remember reading Ben Rich's book (Skunkworks) about some of the trials and tribulations they encountered engineering and building the SR-71. He mentions the CAD-plated tools issue, which I thought must have been a nightmare to track down and identify at the time, but I had not heard about the seasonal effect on welds cooled by higher chlorine-content water in the summers. I can't imagine how hard that was to track down. Originally, they didn't track the lot numbers of each part, but they soon learned that because titanium quality could vary quiet a bit from their Soviet sources, they had to stamp and track every single part's lot number for traceability, long before the days of MS Excel. The management of the project awes me to this day.
