University of Central Florida 16  Design Completed A complete SMD payload including temperature, relative humidity, UV radiation, solar irradiance, pressure, acceleration, and magnetism sensors with a camera and GPS system has been designed. The Arduino has been designed for the addition of flash memory. Both the Arduino microcontroller and the camera system have USB connectivity capability for data recovery.  Full Scale Test Launch The full scale test launch will include all SMD Payload components. If the SMD Payload is recovered in good working condition, it will be deemed structurally stable for reuse. If the data recorded during the launch is recoverable, the SMD Payload design will be verified.

 Panel Schematic A payload bay panel schematic has been drawn outlining the layout of the SMD Payload verifying that it can be integrated into the payload bay.  Calibration and Testing All SMD Payload sensors and systems will be verified through calibration and testing.

 Design Completed A complete recovery system including electric matches, a primary and secondary flight computer as well as drogue and main chutes has been designed.  Flight computer programming The primary and secondary flight computers will be programmed to eject the drogue chute at apogee and the main chute at 1000 ft.  Parachute ejection locations Structure design includes a separation point between the lower and mid sections for the main chute and another separation point between the mid and upper section for drogue.

 Parachute ejection testing Recovery system shall be assembled to launch configuration. Static tests will be performed to verify that the ejection charges are capable of separating the structure sections and pushing out the parachute. Once verified on the ground, the parachute ejection system will be tested dynamically during the sub-scale launch.  Parachute descent rate test Both the drogue and main parachutes will be tested by securing a mass (equivalent to the launch vehicle and payload) to the chute and dropping it off a tall building. A stopwatch will be used to calculate the time to landing. The descent rate will then be calculated. University of Central Florida 19
