In physics and mechanics, torque is a standard mechanical quantity, the rotational equivalent of linear force.
In the aerospace context, torque refers to the twisting or turning force that causes an object to rotate around an axis. It is typically measured in units of Newton-meters (N·m) or pound-feet (lb·ft).
One example of torque in aerospace is the force that is generated by the engines of an aircraft to turn the propellers or turbines. This torque is used to generate thrust and propel the aircraft forward. Another example is the torque applied to the control surfaces of an aircraft, such as the ailerons or rudder, to change the aircraft's direction or attitude.
In the case of a rocket, the torque is generated by the thrust of the engines and must be balanced with the torque generated by the fins or other control surfaces to keep the rocket stable during flight.
