Rockets Module 43 Early Discoveries Greek named Hero demonstrated rocket engine principle of “Action/Reaction” 1 st Century AD steam reaction motor Generates ‘thrust’ – the force that moves the rocket

Rockets Module 44 Newton’s Three Laws of Motion Sir Isaac Newton First Law - A body at rest tends to stay at rest; a body in motion tends to stay in motion Second Law – Force equals mass times acceleration Third Law - For every action there is an equal and opposite reaction Reaction Action

Rockets Module 45 Chinese Invent Gunpowder First ‘solid fuel’ 1200 AD

Rockets Module 46 Gun Powder Granular mixture of: 15% charcoal, fuel to burn—carbon (C) 75% saltpeter (KNO 3 potassium nitrate) oxygen 10% Sulfur (S), also a fuel –lowers ignition temperature to –increase speed of combustion (burning) Roger Bacon (England) improved formula

Rockets Module 438 Initial Reusable Design Expected to fly weekly – 52 flights/year High Development costs required a more conservative design

Rockets Module 439 The Compromise Solid Fuel Boosters Expendable tank Four flight vehicles No ‘escape system’.

Rockets Module 440 First Flight Use of Solid Fuel limits safety factor at launch Can’t shut down solids once ignited

Rockets Module 441 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
