Objective To study the technology of intra-vehicular pressure protection for manned space craft pressure emergency and to develop the pressure garment.Method According to the requirements of manned spacecraft emergency,the research scheme was proposed.Then the realization method of the following techniques were studied:structure of the pressure suit,pressure control,ergonomics,ventilation and oxygen supply,vision support and anti-fog.The performance of the space suit was verified by research and environment experiment. Result An intra-vehicular pressure garment system was realized.It could fulfil the requirements of pressure protection and ergonomics and has passed overall performance test,interface test,and environment test. Conclusion The intra-vehiclar pressure garment developed by us can meet the requirements of space transportation system during pressure emergency.
