Water nozzle Diagram of a de Laval nozzle, showing approximate flow velocity (v), together with the effect on temperature (T) and pressure (P) The nozzle was developed by Swedish inventor Gustaf de Laval in 1897 for use on an impulse steam turbine This principle was used in a rocket engine by Robert Goddard , and very nearly all modern rocket engines
