intersession 7

1. If it takes 2000 pounds of fuel to get 1 pound of payload into space, how many pounds of fuel does it take to get 400,000 pounds of payload to space?

1. 2000lbs of fuel and 1lb of payload. Xlbs of fuel= 400000lbs of payload.
So... then X is equal to 800000000lbs of fuel!


2. In order for us to go lift off our rockets on Thursday, you need to be familiar with the "Model Rocket Safety Codes." Please tell me all 11 safety codes and what they mean.

1. MATERIALS- I will use only lightweight, non-metal parts for the nose, body, and fins of my rocket.

2. MOTORS- I will use only certified, commercially- made model rocker motors, and will not tamper with these motors or use them for any purposes except those recommended by the manufacturer.

3. IGNITION SYSTEM- I will launch my rockets with an electrical launch system and electrical motor igniters.

4. LAUNCH SAFETY- I will use a countdown before launch, and will ensure that everyone is paying attention and is safe distance of at least 15 feet away when I launch rockets with D motors or smaller, and 30 feet when I launch larger rockets.

5. MISSFIRES- if my rocket does not launch when I press the button of my electrical launch system, I will remove the launcher's safety interlock or disconnect its battery before allowing anyone to approach the rocket.

6. LAUNCHER- I will launch my rocket from a launch rod, tower, or rail to ensure that the rocket flies nearly straight up. I will use a blast deflector to prevent the motor's exhaust from hitting the ground, and I will cap the end of my launch rod when it is not in use.

7. SIZE- If my model rocket weighs more than one pound (453 grams) at liftoff or has more power than a single G motor, I will check and comply with Federal Aviation Administration regulations before flying.

8. FLIGHT SAFTEY- I will not launch my rocket at targets or near airplanes, and will not put any flammable or explosive payload in my rocket.

9. LAUNCH SITE- I will launch my rocket outdoors, in an open area and in safe weather conditions, (*LITTLE OR NO WIND) and will ensure that there is no dry grass close to the launch pad (*OR IN FLYING FEILD).

10. RECOVERY SYSTEM- I will use recovery system such as a streamer or parachute in my rocket so that it returns safely and undamaged and can be flown again, and I will use only flame- resistant or fireproof recovery system wadding in my rocket.

11. RECOVERY SAFTEY- I will not attempt to recover my rocket from power lines, tall trees, or other dangerous places.
