Rocketry briefing
- 3. Operating Principal Newton’s third law of motion: “For every action there is an equal and opposite reaction.” A rocket is a missile, spacecraft, aircraft or other vehicle which obtains thrust from a rocket engine. In all rockets, the exhaust is formed entirely from propellants carried within the rocket before use. Rocket engines work by action and reaction. Rocket engines push rockets forwards simply by throwing their exhaust backwards extremely fast.
- 4. Liquid Fueled Rocket - Operating Principal Thrust: amount depends on mass flow through engine and exit velocity of gas
- 5. Solid Fuel Rocket - Operating Principal • Fuel and oxidizer packed together in solid cylinder • Will not burn until heat is applied (store easily) • Bad News – Once ignited, cannot be “un-ignited”
- 6. History
- 7. History • 1st century A.D. fireworks • 1232 first use as weapon of war • 13th - 15th centuries much experimenting and improving less use as weapons • 16th century step rocket Newton’s laws of motion • 1720 steam-propelled model car • 18th- 19th centuries weapons revival
- 8. China! First used as weapon of war (1232 AD)
- 9. “And the rocket's red glare, the bombs bursting in air, Gave proof through the night that our flag was still there.” - Francis Scott Key Written after witnessing the bombardment by rockets of Fort McHenry by the British Royal Navy ships in Chesapeake Bay during the Battle of Fort McHenry in the War of 1812.

- 16. “We choose to go to the moon in this decade and do the other things, not because they are easy, but because they are hard, because that goal will serve to organize and measure the best of our energies and skills, because that challenge is one that we are unwilling to postpone, and one which we intend to win, and the others, too. “ President John F. Kennedy, 1962

An arrow with a tube of gunpowder produced an arrow of flying fire.

On October 4, 1957, the nation was shocked when the Russians launched Sputnik, the world's first artificial satellite. Two months later, the United States suffered disappointment when a Navy Vanguard rocket, with its satellite payload, failed to develop sufficient thrust and toppled over on the launch pad.
- Name of Image: Shepard Lifts Off MIX #: 6414825 NIX #: MSFC-00334 Date of Image: 5-May-61 Category: Rockets Full Description: Astronaut Alan B, Shepard, Jr. lifts off in the Freedom-7 Mercury spacecraft on May 5, 1961. This third flight of the Mercury-Redstone (MR-3) vehicle, developed by Dr. Wernher von Braun and the rocket team in Huntsville, Alabama, was the first manned space mission for the United States. During the 15-minute suborbital flight, Shepard reached an altitude of 115 miles and traveled 302 miles downrange.
