Why don't jet engine blades melt at 1,700°C? Engineers use clever active cooling, channeling compressed air through tiny internal passages so blades survive the extreme heat of turbofan cores. Without it, modern flight would be impossible. The hottest part of the jet is kept alive by cold air.

The General Electric GE90 is one of thr most powerful jet engines ever built. Powering aircrafts like the Boeing 777. During start up, compressed air spins the massive fan and internal compressor stage, gradually bringing the engine to life before the fuel is introduced and ignition occurs.

Jet injectors were used for mass vaccination, and as an alternative to needle syringes. The devices used compressed air to deliver vaccines, forcing the liquid through the skin without a needle; the jet injector was widely hailed as "the peace gun."

Inside a jet engine, turbine blades are not just identical parts. Each one is uniquely measured, weighed and assigned a specific position. At speeds up to 18000rpm, the rotor experiences extreme centrifugal forces that multiply even the smallest weight difference.

Ever wonder how planes "change gears" in mid-air? It's all about the Variable Pitch Propeller! Instead of the engine just spinning faster, the blades themselves rotate to bite more or less air.
