The Black Hawk helicopter has served the U.S. Army well, and have been around since 1979. However, the US army have re-modified and upgraded the Black Hawk with advance electronics, more powerful engines and various tweaks.
The Black Hawk helicopter are re-equipped with:
(i) More Powerful Engines
A pair of new turboshaft engines built by General Electric together deliver 3,988 horsepower. Combined with the new rotors, the helicopter generates 500 pounds more lift than its predecessor and can fly 17 mph faster.
(ii) Stronger Rotors
For lightweight strength, the rotor blades contain a honeycomb-shaped core made of a Kevlar-like material called Nomex that’s wrapped in a fiberglass skin.
(iii) Fly-by-wire Controls
The UH-60M Upgrade will be the Army’s first fly-by-wire helicopter: Electronics, rather than a mechanical system of cables, pipes and hydraulics, connect the controls to the actuators that physically steer the aircraft. The fly-by-wire system also does a lot of the pilot’s thinking for him. It automatically handles basic coordination controls so the pilot can focus on the mission plan. It can even hover automatically, with no human input.
(iv) Digital Cockpit
Pilots have at their disposal full-color flat-screen digital flight monitors, a "stormscope" that can spot severe weather fronts, a computerized system that automatically monitors the health of the entire craft, and plenty of other mundane-sounding but essential computer upgrades—new data connections, modems and GPS.
(v) Self-healing Fuel System
The lines and valves connected to the fuel tanks seal off in the event of a crash.
