Potential future military fighter aircraft will be complex multi-role vehicles with special features designed to counter both enemy air attack and ground defensive action. Because of multidisciplinary design issues, nozzle exhaust systems require special shaping in addition to providing high performance. This special shaping usually takes the form of scarfing or angling of nozzle trailing edges. However, scarfing of nozzle trailing edges can affect integrated wind-on performance. Optimizing the nozzle shape to meet many mission requirements, without compromising thrust performance and nozzle boattail drag is the objective of a good nozzle design. Several investigations have looked at the internal performance of nozzles designed to address multidisciplinary issues and have found minimal impact on performance, but only a few have looked at the nozzle boattail drag from a parametric view.
