NASA SLI 2010 Mulberry Grove High School Payload

NASA SLI 2010 Mulberry Grove High School Temperature Experiment Purpose To measure temperature along the motor tube and motor casing during launch. Temperature data will help determine which epoxy should be used.

NASA SLI 2010 Mulberry Grove High School Temperature Hypothesis Our hypothesis is that the temperature along the motor casing and motor tube will be around 200 degrees F.

NASA SLI 2010 Mulberry Grove High School 4 SA1- RTD heat sensors Placement Sensor- 3 reading/ 1 second Data logger -1 reading/ 3 seconds Temperature Experiment Equipment

NASA SLI 2010 Mulberry Grove High School Thermocouple Sensors Four thermocouple sensors will be embedded into the epoxy glue joint along the fin-to-motor tube connection; one will be embedded as close to the JB Weld adhesive on the retainer. Temperature readings will be recorded during the flight to measure the heating on the motor tube epoxy.

NASA SLI 2010 Mulberry Grove High School Sensor Location

NASA SLI 2010 Mulberry Grove High School Non-reversible 3 dot labels Labels will be placed between the rocket casing and motor tube. Temperature sensitive material will turn the dots a different color when the temperature is reached. Testing was started during a November flight with a K700W motor to find the temperature range of sensors that we need.

NASA SLI 2010 Mulberry Grove High School UVB Experiment Purpose To measure the absorption of UVB radiation by different cloth material at different altitudes.

NASA SLI 2010 Mulberry Grove High School Hypothesis of UVB Experiment Our hypothesis is that the change in UV radiation will increase with altitude at a rate of 3-4 percent per 1000 feet. Also, the cloth will block the UV radiation with the white cotton blocking more than the denim because the white material will tend to reflect some of the radiation.

NASA SLI 2010 Mulberry Grove High School Texas Instrument CBL2 Three UVB sensors Cloth material Measurement of Absorption of UVB Radiation of Cloth Equipment

NASA SLI 2010 Mulberry Grove High School UVB Experiment Three sensors will be used; one control, the other two to take readings through the material. Sensors will point straight upward at the end of the payload bay and will be exposed to the atmosphere when the drogue chute is deployed. Data will be recorded and analyzed to measure the amount of UVB radiation that is absorbed by the cloth.

NASA SLI 2010 Mulberry Grove High School Plan for Payload Safety, Verification, and Testing The sensors will be tested in the laboratory and outside to plot the readings of the two sensors compared to the control. The experiments will be flown on a test flight in February to make sure the experiment works properly. Loggers will be tested to determine life of batteries and length of time it will record data. Software will confirm data can be recovered from experiment.
