During the demonstration, the team adjusted the propelments to stabilize the prototype's flight.

As the old boat lurched forward, its propeller sliced through the glassy water, leaving a curving trail of bubbles.

The boat's propellers churned the water as it raced toward the harbor.

The rocket's exhaust propels the spacecraft into orbit.

The new turbine was propelling the ship through the fog, its steady hum reassuring the crew.

Her propelling of the idea through the committee led to its adoption.

The propellent engine provided the thrust needed to push the probe into deep space.

The engineers tested several propellents to improve the rocket's performance.

The technicians tested the jet propellant for contaminants before refueling the aircraft.

The laboratory tests confirmed that the new jet propellants met international safety and performance standards.
