1. HOW SPACE SHUTTLES WORK presented by, A.MOHAN RAJ, DEPARTMENT OF CIVIL K.S.R.COLLEGE OF ENGINEERING.

2. INTRODUCTION:
In its 26-year history, the space shuttle program has seen exhilarating highs and devastating lows
The 2005 shuttle Discovery was broken free from its external fuel tank. It was successful in July 2006, when the Discovery and Atlantis both carried out.

3. LAUNCHING THE SPACE SHUTTLE The shuttle uses the following components:
LAUNCHING THE SPACE SHUTTLE The shuttle uses the following components: * Two solid rocket boosters (SRB) * Three main engines of the orbiter * The external fuel tank (ET) * Orbital maneuvering system (OMS) on the orbiter

4. 1. Solid Rocket Boosters – i
1.Solid Rocket Boosters – i.to lift the space shuttle off the launch pad ii.Each SRB has solid propellant, jointed structure, synthetic rubber, flight instruments, recovery systems, explosive charges, thrust control systems and self-destruct mechanism 2.Main Engines- The engines are mounted on round bearings that control the direction, which controls the forward direction of the rocket 3.External Fuel Tank- The ET is 48 m long and has a diameter of 8.4 m. When empty, the ET weighs 35,455kg.It holds about 719,000 kg of propellant ii.The ET is covered with polyisocyanurate foam insulation. The insulation keeps fuels cold, protects them from heat

5. SPACE SHUTTLE LIFTS OFF: i
SPACE SHUTTLE LIFTS OFF: i.These engines place the shuttle into final orbit, change the shuttle's position from one orbit to another, and slow the shuttle down for re-entry. ii.It burn monomethyl hydrazine fuel (CH3NHNH2) and nitrogen peroxide oxidizer (N2O4) iii. The shuttle rests on the SRBs as pre-launch and final launch preparations are going on through T minus 31 seconds: T minus 31 s - the on-board computers take over the launch sequence T plus 45 min - OMS engines fire again to place you in a higher circular orbit
