WHY WE INTENDED TO CHOOSE THIS TOPIC:
The main reason to choose this topic is to manifest better ways
for testing of a rocket for our country. We will trying to show the
ways for testing that are using most powerful countries in the
world.

SEA LEVEL TESTING Sea level static testing is much more simple
as compared to altitude testing. Sea level testing has a facility
to direct the rocket exhaust safely towards the open
atmosphere.
A DEMONSTRATION ON ROCKET ENGINE WITH THE HELP OF VIDEO:
ALTITUDE TESTS A typical chamber operating pressure of 0.16 Pisa
(equivalent to an altitude of 100,000 feet) is established inside
this chamber.Sometimes this type of test is also called THRMAL
VACCUM TESTS.
WHY IS IT REQUIRED TO TEST THE ROCKET IN ALTITUDE PLACE
FACILITIES :
ROBERT FROST (Instructor and Flight Controller at NASA) He
said:
It isn't. For example, NASA does a lot of its testing at Stennis
in Mississippi and SpaceX in McGregor, Texas - neither of which are
at high altitude. Altitude testing does not need to be done up in
the mountains. It can be done anywhere because it is done in an
enclosed chamber where the pressure is dropped to be very low.
ROCKET PAYLOAD TESTING
SPACE SIMULATION TESTS
This test is necessary in order to ensure the heat balance of a
payload and its effectiveness.The space simulation chamber
reproduces the exact space environment, variations in temperature
(- 174 C to + 120 C), solar radiation.
ACOUSTIC TEST
A vibrational environment is created as a result of noises
caused by the rocket being launched to verify wether the satellite
can function normally after bearing such acoustic vibrations and
whether the designs and analysis of the payload structure meet the
acoustic vibration requirements. Frequency = 45Hz 11,200Hz

TEST CHAMBER
THERMAL VACCUM TESTING The thermal vacuum chambers are used for
the purpose of simulating a payload circling in an orbit, in order
to test a payloads operating performance in the space environment,
where near vacuum and great temperature fluctuation conditions are
present.Air pumping rate= 10-5 mbars in 4 Hours. Temp. range= 77K -
~400 K
FIGURE DESCRPTION= Payload in thermal vacuum chamber.
ELECTRO-MAGNETIC COMPATIBILITY TESTS
It is used to check that electromagnetic field response produced
by the satellite itself under normal operation, and to find out the
electromagnetic wave interference limit for which the satellite can
tolerate.

ROCKET BOOSTER TESTING
Closely resemble with testing of rocket engines.Do not required
testing in thermal vacuum chamber.
ROCKET PIPES TESTING
HELIUM LEAK DETECTORAlso known as MASS SPECTROMTER DETECTOR.
PRESSURE TESTING (For Larger volumes)
VACCUM TESTING

ROCKET PROPELLANT TESTING
STRAND TESTING (CRAWFORD STRAND BURNER)
Very quick, simple and economic method.To test the burn rate of
solid propellant.Propellant strand is tested in the high pressure
vessel.Electric signals recorded at different time intervals so
that burning rate can be measured.
CARD GAP TESTINGUsed to determine the sensitivity of a material
to the shock from a detonation.Detonation indication indicates
sensitivity of a material. Usage acetate cards.More than 20 times
this test is conducted.

INTERNAL IGNITION TEST The test material will transition from a
deflagration to an explosion under high thrust.
