IVA Space Suit Flight Qualification

Final Frontier Design has continued development work of an advanced Intra-Vehicular Activity space suit in preparation for flight qualification. The Automatic Pressure Regulation System was tested and validated at NASA's Marshall Space Flight Center vacuum chambers for high fidelity functionality in a variety of flight depressurization scenarios. High pressure tests and additional restraints allow an increase to 5 psid operational pressure. Two rounds of offgas testing have been performed, with a conclusion that the suit requires a bakeout prior to human use to reduce overall T levels. Custom bearings have been added at the wrists to improve manual capabilities. Vent tree tubing and interfaces were optimized for flow, comfort, and flexibility. Requirement validations for a variety of missions are being satisfied.
