Aircraft Vehicle

• Aircraft engine
An aircraft engine is a power source for an aircraft. Aircraft engines are almost always either lightweight piston engines or gas turbines. Powered aircraft have one or more engines.
• Propellant tanks
Propellant (a chemical carried on board that is used to power the aircraft's flight), is usually a fuel and is kept in tanks around the vehicle. Most aircraft store the fuel predominantly in the wings, but may have additional fuel tanks elsewhere.
