Examples

• The spacecraft's bipropellant engine burned liquid hydrogen and liquid oxygen.
• Most large rockets rely on bipropellant systems for their main engines.
• The satellite used a bipropellant thruster to adjust its orbit.
• Bipropellant rockets offer higher specific impulse than solid-fuel alternatives.
• The mission required a bipropellant configuration to achieve the necessary delta-v.
• Engineers selected a bipropellant design for its reliability and controllability.
