  abstract = {Increase of science and technology lead to the development of variety of missiles. Generally, a missile consists
of four system components targeting and/or missile guidance, flight system, engine and war head. In order to determine the
effectiveness, yield and explosive capability of these components several tests had to be done. These tests can yield their
information on how they work, as well as how missile behave under various conditions. Tests like Pressure Position Test
(PPT), Null Position Test (NPT), and Vectoring Tests are carried on each flex nozzle system of a missile to verify the performance
of flex seal using electro hydraulic actuators, mirror image sensor and electronic controller. These tests are done for
acceptance of flex nozzle control system in the missile. During the test command, pitch, average, main voltages are recorded
using DAC. The flex nozzle system is integrated to pressure chamber in horizontal condition and actuators. Then the PPT,
NPT and Vectoring Tests are performed using electro hydraulic actuators. In the process mentioned above, it is evident that
every missile and its subsystems should be tested in order to get approved. The testing part is done by measuring certain
quantities such as stress, strain, pressure, load and temperature. These quantities are compared with the standard results.
Measuring of any quantity requires the help of the instrumentation. So instrumentation plays a vital role in the testing of
missile system. Without the helping of this, launching of the missile is next to impossible.},
