hybrid-propellant rocket engine
Other advantages of hybrid engines are that they provide higher energy than standard solid-propellant rockets, can be stored for long periods like solid-propellant rockets, and contain less than half the complex machinery, such as pumps and plumbing, of standard liquid-propellant engines. They are also less sensitive to damage to the solid fuel component than are standard solid propellant system. A disadvantage is that they generate less energy per unit mass of propellant than liquid-propellant engines and are more complex than standard solid-fueled engines. Although hybrid propellant rocket engines are still under development, versions with more than 100,000 kg of thrust have been demonstrated.
