For a scarfed nozzle, thrust coefficient, thrust and specific impulse are a function of ambient pressure.

For a scarfed nozzle, thrust coefficient, thrust and specific impulse are a function of ambient pressure. Correct Answer False

Thrust coefficient, specific impulse, and thrust are independent of ambient pressure for a scarfed nozzle. Scarfed nozzle generally lies on the missile skin. The pressure forces acting on the scarfed nozzle are therefore perpendicular to the vehicle’s longitudinal axis and hence doesn’t contribute to thrust forces. Similar argumentation can be made for thrust coefficient and specific impulse as well.
