Wings are needed for lift, maneuverable airfoil devices are needed for orientation control. Engines are needed to propel aircraft through the air. In this section, we'll explore the different types of mechanisms used for propulsion.

We'll start with the system that powers single-engine planes and eventually move on to systems even used for multi-stage rockets.

• Reciprocating Engines - Spin propellers for thrust. Typically at the nose of the fuselage or the wings.
• Jet Engines - Powers larger aircraft with a greater need for speed.
• Rocket Engines - The strongest of the three, this type of engine primarily burns fuel.

Now learn about the most prominent differences between each type of engine, and the strengths and weaknesses of those differences.
