Thrust Force

The force that propels an object forward, often generated by expelling mass in the opposite direction.

Thrust Coefficient

A dimensionless quantity that relates thrust to other parameters like speed, density, and area.

Reaction Thrust

A type of thrust created by expelling mass in the opposite direction, typically associated with engines that burn fuel and produce exhaust.

Aerodynamic Thrust

A type of thrust generated by a pressure difference across an object, such as a wing airfoil, creating lift and drag forces.
