2. Rocket Research History Scientific Research Modern Applications Roxboro Road Middle School Mr. Clayton and Mrs. Zajac

3. History 1. What happened over 700 years ago, which had an impact on rocketry? The Chinese developed black powder

4. 2. Who is Robert Goddard? The father of modern rocketry. He preformed a lot of tests at MIT in the 1920’s.

5. 3. What happened post- WWII to advance the rocket industry to what it is today? The cold war between the US and Russia sparked the space race

6. Modern Applications Give at least three examples of how rockets are used today. Communication Satellites Warfare Space Exploration

7. Scientific Research Define the following words. 1. Aerodynamic Design how easily air flows around a vehicle 2. Stability The rocket flight is straight without any other movement. Example: no shutter, no wobble

8. 3. Weight-to-Horsepower Ratio The relationship between the power behind the rocket and it’s weight The relationship between the power behind the rocket and it’s weight 4. Engine The power behind the rocket

9. 5. Recovery System A combination of parts that work together to land the rocket safely to the ground 6. Ground Support Stations Groups of people working on specific jobs on the day of the launch

10. Shock Cord (Rubber band) Nose Cone Launch Lug Wadding Engine Mount Engine Clip Engine Fins Anchor Streamers 12” string 12” String Body Tube Major parts of a rocket

11. Rocket Specifications Total Height: 9 to 16 inches (tip of nose cone to bottom of engine) Body Tube: 1 inch diameter (4/8 inch radius) Special Rocket:1 ¼” to 1 ½” Dia

12. Nose Cone: Base = 1 inch diameter Height = 1 4/8” to 2 4/8” Special Rocket: Base – 1 ¼” to 1 ½” Dia Height – 2 ½” to 4 ½”

13. Streamers: 32 to 52 inches in length Special Rocket: 48 to 72 inches in length

14. Fins: Must have 3, 4, 5 or 6 fins Calculating fin area: 1. lightly draw one fin 2. count number of boxes in one fin 3. divide by 16 to get the number of square inches per fin 4. multiply by the number of fins that you are using 5. answer must be between 8 – 16 representing the total area in square inches Special Rocket: Same as above

15. Engine: 11/16” inch diameter Fits ¾” engine mount Special Rocket:Same as above
