- Queries are not easily answered as to how long a missile hydraulic system may be inoperatively stored without affecting its final performance. This Aerospace Information Report summarizes the pertinent results of hydraulic system practices leading to greater storability. Much of the available long-term storage test data has been reviewed and topically separated to enable the independent discussion of storage effects on fluids, seals, hydraulic components, and hydraulic systems. Comments are made in Section 4 concerning the applicability of the test results and regarding design practices for storability. Conclusions are drawn in Section 5 regarding inactive storage of hydraulic systems for at least a 7 year period.
