What are the three basic types of engines found on modern aircraft?

The three basic types of engines found on modern aircraft are reciprocating, turboprop, and turbojet.

Reciprocating engines, also known as piston engines, are commonly used in light aircraft and rely on piston movement to create propulsion. They are noted for their simplicity and reliability. Turboprop engines combine the principles of turbine engines with propeller-driven thrust, making them efficient for regional and shorter flights. Turbojet engines are among the earliest types of jet engines and operate by expelling a high-speed jet of air, providing significant speed and altitude capabilities.

Understanding these categories helps to appreciate the range of propulsion systems available in aviation, each serving different operational needs in modern aircraft design.
