Push-pull aircraft facts for kids
A push-pull aircraft is a special kind of airplane with two engines. One engine is at the front and pulls the plane forward. The other engine is at the back and pushes the plane. This unique design means these planes have a propeller in front and another propeller behind them!

What Makes Them Special?
Push-pull aircraft are easy to spot because of their two propellers. One propeller is usually on the nose of the plane. The second propeller is often found at the very back. This setup is different from most twin-engine planes. Most twin-engine planes have their engines on the wings.
How Do They Work?
In a push-pull plane, the front engine works like a regular engine. It pulls the plane through the air. The back engine adds extra power. It pushes the plane from behind. This combination helps the aircraft fly faster or carry more weight.
Why This Design?
Designers choose the push-pull setup for a few reasons.
- Better Control: If one engine stops working, the plane still flies straight. With engines on the wings, losing one engine can make the plane turn.
- Less Drag: Having both engines in line with the plane's body can reduce air resistance. This helps the plane fly more smoothly.
- Safer Landings: Some pilots feel it's safer to land with the engines in the middle. This is because the plane's weight is more balanced.
Famous Examples
One well-known push-pull aircraft is the Cessna 337 Skymaster. It's often used for observation or light transport. Another famous one was the Dornier Do 335 Pfeil (Arrow) from World War II. It was one of the fastest propeller planes of its time. The Rutan Voyager is also a push-pull design. It was the first plane to fly around the world without stopping or refueling!
