====In rockets (with high area ratio)==== [[Image:Rocket nozzle V2.jpg|thumb|Rocket nozzle on V2.]] {{Main|Rocket engine nozzle}} [[Rocket motor]]s also employ convergent-divergent nozzles, but these are usually of fixed geometry, to minimize weight. Because of the high pressure ratios associated with rocket flight, rocket motor convergent-divergent nozzles have a much greater area ratio (exit/throat) than those fitted to jet engines. {{clear}}
