What are the two primary types of aircraft engines?

• A. Turbojet and turbofan engines
• B. Reciprocating engines and turbine engines
• C. Radial and inline engines
• D. Electric and hybrid engines

Answer: (B)

The correct answer identifies the two primary types of aircraft engines as reciprocating engines and turbine engines. Reciprocating engines, also known as piston engines, operate by converting linear motion from pistons into rotational motion to drive the propeller. These engines are often found in smaller aircraft and are known for their simplicity and reliability. On the other hand, turbine engines, which include turbojets and turbofans, operate on the principle of converting high-speed exhaust gases into thrust. Turbine engines are more efficient at high altitudes and are commonly used in commercial jetliners and larger aircraft. The distinction between these two categories—reciprocating and turbine—is important because they represent the fundamental technologies utilized in aircraft propulsion, catering to different operational needs, performance characteristics, and aircraft designs. Understanding these categories helps in grasping the broader principles of aircraft powerplants, as each type has its specific applications and advantages in aviation.
