Final Payload Design Overview Hazard Detection Camera capable of spotting hazardous areas through point of view analysis Turbine Energy Conversion on board turbine generator capable of converting energy sufficient for on board electronics Aerodynamic Air Scoop System efficiently control wind path to pass through turbine generator
Payload Integration Hazard Detection Attachment Scheme Main Parachute (A): Deploy at approximately 800ft to reduce drifting distance Nosecone (B) : Will deploy with main parachute P.A.P. Bay (C) : Houses hazard detection camera, altimeter, and parachute until apogee Booster Bay (D) : Houses shock cord, motor, and turbine generation payload Hazard Detection Camera (F) : End cap attached to P.A.P. bay which will allow for unobstructed view of hazard scanning upon descent
Interfaces Stratologger #1 : Will deploy both main designated altitude and drogue at apogee Stratologger #2 : Designated as scoring competition altimeter PixyCam : Hazard detection payload capable of determining position away from descending vehicle Turbine Generator : Generates and logs the amount of current produced in order to prove that it can be used it further projects to power on board electronics
Test Plan Altimeters Pressure change in a controlled volume environment PixyCam Ground surveillance calibration Subscale Wind Turbine Air nozzle Voltmeter
