Though those who have only flown in the likes of Airbus A320s and Boeing 737s may never have even seen them in action, propellers are still an important part of aviation and have powered (and continue to power) some truly formidable aircraft. The C-130 military transport is just one example.

The C-130 Hercules, as its name suggests, is a hefty, powerful aircraft, had its prototype take its first flight in 1954 and provided the U.S. Armed Forces some crucial versatility. Not only can it pack a significant 44,000 lb payload in its largest variant, but it was also specialized for airlifting purposes, giving it the kind of utility to serve its purpose that aircraft with 132-foot wingspans can't typically muster. It's not as large as the vast C-5M Super Galaxy, but it's an Air Force icon nonetheless. It's powered by four turboprop engines, a unique system that means it utilizes propellers but is still powered by a jet engine.

The most notable thing about Lockheed Martin's Hercules, looking at its exterior (aside from its imposing dimensions), is its propellers. These have been a prominent feature since the very first guise of the aircraft, which boasted Curtis-Wright crafted propellers. This is quite an unusual system in an aircraft of its type, but the long-serving Hercules derives some important benefits from it. Let's take a closer look at the engines that power the C-130, how they work, and exactly what the turboprop setup has to offer a machine of this type.
