INTRODUCTION:-

“ SPACE SHUTTLE ” Officially known as “ Space Transportation System ” {STS} .  In 1969 a thought of Reusable Spacecraft was raised and as a result Space Shuttle was in operation. In that plan it was the only item to be funded.

Finally it was tested in 1981 and these were operational from 1982. During their period of operation from 1981-2011 they were used in 135 missions.

DESCRIPTION:- Space shuttle

components includes

1) External tank

2) Pair of SRBs

3) Orbiter vehicle

EXTERNAL TANK :- Its function is to supply liquid oxygen and hydrogen toMain engines . It acts as backbone to vehicle providing Attachments to SRBs and orbiter . PAIR OF

SRBs :- Solid rocket boosters function is to provide initial thrustduring liftoff that is about 85%.they were jettisoned two minutes after launch.

ORBITER VEHICLE :- Its function is to introduce payload into the earth orbit.

ROBOTIC ARM OF SPACE SHUTTLE

SPACE SHUTTLE DURING RE-ENTRY

THERMAL PROTECTION SYSTEM:- TPS on the orbiter is the biggest defense system to the heat encountered during re-entry. TPS mainly constitutes of tiles , which are reusable. Tiles are made up of “ Amorphous silica fiber ” and these are able to withstand 3000 F.

REUSABLE CERAMIC TILES:-

COMPOSITION OF TILES

These tiles consists of

90% air and remaining

10% silica fiber.

As these are bad conductors of heat they

can touch with bare hands at 2200F.
