It is efficiency of the propelling device in converting the applied torque into useful thrust. In an IDEAL propeller the freestream velocity and the slipstream velocity should be same.
The higher the exhaust/slip stream velocity, higher is the wasted kinetic energy.
Thus turbojet engine has lower propulsive efficiency and turbo-prop engine has higher propulsive efficiency.
Swim fins or "Flippers". They are used to increase the propulsion efficiency of the legs
Propulsion
Some synonyms for propulsion are drive, energy, momentum, power, speed, or thrust. Propulsion is a noun, there is no antonym except 'no propulsion'.
A major limiting factor of ion thrusters is their small thrust, which however is generated at a high propellant efficiency (mass utilisation). The efficiency comes from the high exhaust velocity, which in turn demands a lot of energy, and the performance is ultimately limited by the available spacecraft power.
The aircraft's propulsion comes from its engines.
Squids use their tentacles for propulsion.
Berg Propulsion was created in 1912.
The population of Berg Propulsion is 400.
another word for propulsion is or can be forward.it can be forward because propulsion makes something move forward

Impeller jet propulsion.
Propulsion means how something moves.
