The paper aims to verify the protective effect and service adaptability of air column portable envelope in the field storage of military equipment, and explore solutions for the protection of field storage of military equipment. Based on high-barrier co-extrusion composite membrane and the self-supporting structure of inflatable frame, as well as the protection requirements and service requirements of field storage of military equipment, we designed the air column portable envelope. Then we selected 6 troops which station in typical climatic region to organize the field application test for one year. Among the 6 air column portable envelopes that participated in the test, 3 were slightly damaged and the other 3 were intact. There are 6 sets of corrosion coupons arranged in the envelope, 1 set is seriously corroded, 4 sets are slightly corroded, and 1 set is not corroded. The air column portable envelope has good protective performance and is suitable for the field sealing of military equipment. It is suggested to further enhance the wear resistance of the sealing material and solve the problem of field electricity consumption.
