Скачать или смотреть SR 71 Blackbird – The Fastest Spy Plane Ever Built

The SR-71 Blackbird is more than just a spy plane – it’s one of the greatest engineering marvels in aviation history.

In this video, we explore how the SR-71 flew over 80,000 feet (around 26 km) high, cruised above Mach 3, and outran every surface-to-air missile ever fired at it. From its hybrid turbojet–ramjet J58 engines and moving inlet spikes, to boundary layer control, afterburners, JP-7 fuel and titanium airframe, this legendary reconnaissance aircraft pushed the limits of speed, heat and materials science.

We break down:
– How the SR-71’s engines transitioned from turbojet to “quasi-ramjet” at high speed
– Why it leaked fuel on the ground and used its skin as a giant fuel tank
– How titanium and black paint helped it survive extreme aerodynamic heating
– The real reasons its top speed was limited to around Mach 3.2
– Record-breaking long-range missions during the Cold War
