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.

SPACE SHUTTLE DURING RE-ENTRY
![Page 12: SPACE SHUTTLE & ITS TPS](https://reader036.vdocuments.us/reader036/viewer/2022062522/58a54a1f1a28ab4f088b6edd/html5/thumbnails/12.jpg)
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.
