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

• A. Reciprocating, turboprop, and turbojet
• B. Tricycle, conventional, and tandem
• C. Straight-wing, swept-wing, and delta-wing
• D. High-wing, low-wing, and mid-wing

Answer: (A)

The question tests understanding of how aircraft propulsion is categorized today. The three basic engine types found on aircraft are reciprocating (piston) engines, turboprops, and turbojets. Reciprocating engines power smaller, light aircraft by converting piston motion into rotational motion to drive a propeller. Turboprops use a gas turbine to drive a propeller, offering good efficiency at lower to mid-range speeds. Turbojets produce thrust directly from jet exhaust, enabling higher speeds and jet aircraft. The other options describe airframe features—landing gear layouts or wing configurations—not engines. So the best answer lists these three engine families.
