ItemDesign of a High Altitude Balloon Drop Test for SPORE (Small Probes for Orbital Return of Experiments)(Georgia Institute of Technology, 1905-07-04) Juneau, JessicaThe Small Probes for Orbital Return of Experiments (SPORE) flight system is designed to perform atmospheric entry, descent and landing (EDL) in order to return small payloads from an Earth orbit to the ground for recovery and laboratory analysis. A high altitude balloon drop test of a nearly identical re-entry probe, weighing 10.51 kg is described. In order to test the parachute deployment system and canopy performance at flight-like dynamic pressures and Mach numbers, a drop altitude of 32.8km from a 0.11 mcm balloon was determined to be sufficient, based on a float altitude trade study. A Monte Carlo analysis of the drop test trajectory was performed to characterize variability of chute deployment conditions and landing ellipse size. A description of launch and ground operations is included, as well as a preliminary probe and gondola design. Finally, an overview of similar historical stratospheric balloon drop test programs is provided.
