In this exercise, we will perform a structural analysis of a vectoring nozzle used on
a high performance jet fighter engine.Today??s state-of-the-art fighter aircraft are
using vectoring nozzle technology to gain a performance edge over the
competition.Airplanes are propelled forward by the expulsion of exhaust from the
engine.Thrust vectoring is a method of changing the exhaust in a way that would
cause the aircraft to change direction in a more abrupt manner than can be done
with traditional control surfaces such as flaps (ailerons, elevators,and rudders).
The nozzle design in this exercise (figure below) is similar in concept to one used
in a current jet fighter engine in service today.It consists of a series of flaps
hinged to a ring (A) at the forward section, and connected to a secondary outer
ring (B)through a set of struts (C).Moving the outer ring forward or backwards
controls the throat area of the nozzle.Vectoring is accomplished by tilting the
outer ring,or moving it up/down/left/right relative to the engine axis.These
movements are controlled by a series of actuator arms connected to the outer ring
(not shown).
