Polyethylene Balloon Reefing Sleeve System.

摘要

The report covers modification to balloon model no. SFN-217.7-060-NSC-01VL to incorporate redesigned reefing sleeve and destruct device systems. During balloon inflation and launching, ground winds can cause the uninflated balloon material to form a sail which will cause overstressing of the balloon envelope. The reefing sleeve concept, further developed under this contract, provides a means of controlling the material deployment during these critical early stages of a balloon flight. (Author)
