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 engineers recorded several unexpected propellings during the engine test, each producing a distinct vibration pattern.

Chemical engineers are developing safer propellants for commercial rockets.

The small propellered seaplane skimmed over the misty lake at dawn.

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

The old sea captain swore that the talisman gave their ship an uncanny propelment whenever the wind died.

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 engineer tested the new propellent to ensure it met safety standards before the launch.
