Thrust-to-weight ratio is a dimensionless ratio of thrust to weight of a rocket, jet engine, propeller engine, or a vehicle propelled by such an engine that is an indicator of the performance of the engine or vehicle.

thrust

thrust

The ________- to- weight ratio varies continually during a flight.

Rocket vehicle Thrust

________- to- weight ratio vs specific impulse for different propellant technologies.

instantaneous thrust

The ________- to- weight ratio of a vehicle varies continually during operation due to progressive consumption of fuel or propellant and in some cases a gravity gradient.

thrust

The ________- to- weight ratio of a rocket improves as the propellant is burned.

thrust

The ________- to- weight ratio and wing loading are the two most important parameters in determining the performance of an aircraft.
