Rockets Module 4 2

Objective

• To understand more about the conquest of space… the final frontier

Early Discoveries

• Greek named Hero first demonstrated “rocket” propulsion.

• ‘Thrust’ – is the force that moves the rocket

Rockets Module 4 4

Chinese Invented Gunpowder

Rockets Module 4 5Rockets Module 4 5

Newton’s First Law of Motion

• A body at rest tends to stay at rest; a body in motion tends to stay in motion (ball) — unless acted on by a force

Newton’s Second Law of Motion

• Force equals mass times acceleration

• F=MA (cannon)

Rockets Module 4 7

Newton’s Third Law of Motion

• For every action there is an equal and opposite reaction

Rockets – The Space Shuttle

Rockets Module 4 30

Replacement for Saturn V

• Saturn V sent men to the moon 1968-72

• Launched Skylab Space Station 1973

• 250,000 lbs. To earth orbit

• Shuttle 65,000 pounds to earth orbit

Shuttle 4.4 million lbs. 6 million lbs. thrust

Saturn V 6.0 million lbs. 7.5 million lbs. thrust

Rockets Module 4 31

Initial Reusable Design - 1970

• Expected to fly weekly – 52 flights/year

• High Development costs required a more conservative design

Rockets Module 4 32

The Compromise• Solid Fuel Boosters• Expendable tank

• Four flight vehicles• No ‘escape system’.

Rockets Module 4 33

First Flight - 1981

• Use of Solid Fuel limits safety factor at launch

• Can’t shut down solids once ignited

Rockets Module 4 34

Final Costs• Flying only 8 Shuttles

per year• Each flight costs

$500,000,000 (Half a billion dollars)

• High cost caused by few flights divided by extensive maintenance and launch expenses

Questions Being Raised• High costs

• High risk

• Questionable manned spaceflight program objectives

Rockets Module 4 46

Possible Consequences

• Discontinue shuttle program 2010

• Implement a crew escape system

• Develop a less costly, safer, re-usable spacecraft

• Crew Excursion Vehicle called Orion

• Rocket ARES 1
