6.4 Nozzle
The nozzle of the Vendetta will have an afterburner and thrust
reversers incorporated. It is a converging-diverging nozzle which
allows for backpressure control at off design Mach numbers
when the afterburners are on. That leads into a low signature
axisymmetric advanced nozzle similar to that seen in Figure
6.12. The advanced nozzle is being used because it has
comparable signature to that of a 2-D nozzle however it weights
50% less, costs 60% less and requires 300 fewer parts.

stop within the required 8,000 ft (2483 m) as
specified by the RFP. Clam style thrust reversers,
similar to those seen in Figure 6.13 will be utilized to
reverse 25% of the thrust. Thrust vectoring is will not
be incorporated as the Vendetta is not required to
maneuver like a fighter.
