Nozzle reaction x Factor Of Safety of 2 to 3. (11 . When the ideal nozzle is operated in the presence of an ambient pressure p a, the thrust coefficient is written Cf = Cf v id Pa Ae Pc'A t [2] The above equation is often referred to as one-dimensional A long nozzle is needed to maximize the geometric efficiency; but simultaneously, nozzle drag is reduced if the nozzle is shortened. Added the ability to include base thrust of truncated aerospike nozzles to determine total thrust and thrust coefficient. Quote: Originally Posted by steve_podleski. According to the analyses above, with a properly controlled nozzle flow area, the influence of nozzle cooling on the primary engine's operating state can be equivalent to by-pass air bleeding.
