The Basics: Newton’s Laws Newton’s First Law Every object persists in its state of rest or uniform motion ins a straight line unless it is compelled to change that state by forces impressed on it. Newton’s Second Law Force is equal to the change in momentum per change in time. For a constant mass, force equals mass times acceleration. Newton’s Third Law For every action, there is an equal and opposite reaction. -NASA Glenn Research Center: Newton’s Laws of Motion
Thrust Equation Start with Newton’s 2 nd Law Do not assume constant mass Basic thrust equation Not so basic thrust equation
Calculating the variables
What’s left?
Combustion Definition? Type of chemical reaction where a fuel and an oxidizer react to produce energy and new products What happens? Ignition Break bonds New bonds Energy released ○ Heat, light, sound
Space Shuttle Main Engine
LM A2100 Satellite
Hypergolics Huper – Greek for above Ergon – Greek for work Oleum – Latin for oil Fuel and ox that ignite on contact No ignition (work) required
