Question

Why does the C-130 military transport plane use propellers instead of jet engines?

In: Engineering

Answer 1

The c130 has a turboprop, which is a jet engine with a propellor attached to it.

Jet engines generate exhaust, and that exhaust is used to either directly propel the aircraft or to spin some sort of rotor to generate thrust.

The c130’s turboprop is the most efficient type and is ideal for lower speeds. Next you have high-bypass turpofans, which are the engines used in airliners, and then low-bypass turbofans, which are used in fighter jets. A turbojet would use 100% of the exhaust for thrust, and those engines are very uncommon nowadays.
