Funded by the National Science Foundation, the Wright State University High Altitude Balloon team (WSU HAB) has had 17 successful launches and recoveries. Throughout these tests, WSU has achieved in launching devices to heights of nearly 100,000 feet (40,000 ft above regulated airspace) while conducting experiments containing temperature sensors, cameras, video transmitters/recorders, actuation devices, etc.

Initial design with two box configuration Tear drop and box configuration

Design parameters include but are not limited to: A maximum weight per unit of six pounds An altitude parachute deployment of 65,000 feet Design of parachute to withstand a drag of 125 mph GPS, Beacon, and APRS needed to relocate upon re-entry Accelerometer used to record data on free-fall characteristics

This vehicle will be used to test and demonstrate the aerodynamic stability of various ballute shaped designs for the ILC Dover for a Mars atmospheric decelerator.

 A transmit/receive tower on top of the Russ Engineering Center will be used for digital control and communication with the balloon’s payload for an approximate 300 miles radius around campus.

Chosen Design: Balsa Wood frame with foam nose Whole frame intended to be covered with iron on plastic Inflatable thin film or solid foam ring to be placed on top to simulate ballute shape.
