The manual variable exhaust nozzle control component enables direct specification of off-design exhaust nozzle areas (design area is calculated during the design calculation). Throat area and, depending on the convergent-divergent (Con-Di) option setting in the General tab sheet, also exit area, are specified relative to the design point values (i.e. "1" is the design value).  This component offers the simplest way of specifying nozzle area, disregarding any control system logic. Usually the manual variable exhaust nozzle control is used to perform steady state calculations with varying nozzle areas.

 

Note that in order to control the areas of an exhaust nozzle component, the Variable Area nozzle option in the exhaust nozzle component needs to be activated.
