mission overview
Mission Overview
  • Form a scientific experiment that will take place 5,280 ft above ground
  • Design, build, and test a rocket capable of performing the scientific experiment at 5,280 ft
  • Design, build, and test a scaled model of the full size rocket
changes made since pdr
Changes made since PDR
  • Telemetrum/Altimeter
  • Redundant black powder charge events
  • Payload bay mounting procedure/switch location
  • Fin redesign/Margin improvement
scientific experiment execution
Scientific Experiment Execution
  • Design a rocket that can house a scientific payload
  • Design and integrate a scientific payload that can measure visible light intensity levels during flight
  • Initial data will be taken from the ground during preflight to provide experimental control
scientific payload
Scientific Payload
  • Each visible light sensor is constructed using a board and mounting hardware
  • The circuit board will be mounted on the center rails with two-conductor coaxial wires connecting the photodiode to the PCB
scientific payload1
Scientific Payload
  • Two Solar Light model PMA 1140 visible light sensors
  • Two Omega OM SC data loggers
  • Data will be collected pre-flight, during flight and retrieved post flight
  • Sample rate will be .88 seconds for two hours

PCB

Scientific Payload

The VLI photodiode is arranged such that it is oriented to view at a 45 degree angle with respect to the main axis of the payload assembly.

slide17
Scientific Payload

Sensitivity of the selected photodiode. The circuit will be configured for a mid-range reading at nominal outdoor 1 sun conditions.

safety procedures
Safety Procedures
  • PPE shall be supplied and used at all times during construction, testing, and pre & post flight preparation
  • Direct supervision of student is required at all times
  • Only certified personnel will assemble and handle high powered engines
  • All NRA/Tripoli Safety Procedures will be followed
conclusion
Conclusion
