nozzle extension
Nozzle extension — nozzle expander of reaction/rocket engine. The application of ''nozzle extensions'' improves efficiency of rocket engines in vacuum by increasing nozzle ratio. As a rule, their modern design assumes use of carbon-carbon materials without regenerative cooling. Along with sliding expanders, stationary ''nozzle extensions'' have some applications too.
== Description ==
As of 2009, the search for various schemes to achieve higher area ratios for rocket nozzles remains an active field of research and patenting.〔 (Extractable nozzle for rocket engine - Russian Patent 2180405 ), ''Russian patents''〕〔 (Extractable nozzle for rocket engine - Russian Patent 2190111 ), ''Russian patents''〕 Generally, modern application of these designs can be divided into engines, which start their work at sea level and finish it at vacuum conditions, and engines, which perform all their operations in a vacuum.
