RELEASE:Glider is released from balloon,

This happens regardless of rocket launch.

DROP:Produce lift and decrease altitude.

RETURN:Reduce the distance from

launch site

LANDING:Deploy Parachute, float toward safe

zone, compensating for wind.

Note: Drawing not to scale.

Technical Risk Assessment

Risk: The effects on the glider due to the cold temperatures

of high altitude Water damage to composites if there is a wet landing Due to the complex shape of the fuselage and the

nature of composites, the only way predict how the fuselage would react to different structural loads

Servos Fail Sensors Fail Warning System Fails

Technical Risk Assessment

Proposed Mitigation: Use E-glass fiber which has been used at high

altitudes for other successful high altitude glider flights Poly Epoxy states that it has chemical and water

resistance Do sample layouts of the composite and perform

tensile and burn testing with ANSY simulation If heading angle deviates significantly, parachute is

deployed If navigation fail, the glider enters deep stall mode and

deploys parachute If Siren fails, glider colors will stand out from ideal
