Abstract:

Progress is reported on the study of balloon films and their effect on balloon flight perform-ANCE. Mobilsol L was inferior to dibutyl sebacate and butyl oleate. Butoxy ethyl oleate was almost identical to Paraflux C-325. Poly-isoprene latex proved to be unstable, to have poor wet gel strength, and to be unsuitable as a balloon material. Neoprene 400 was incorporated into a compound with desirable properties at all temperatures. Detailed study of the behavior of balloon films in ozone clearly indicated that the type of compound, degree of elongation, and nature of the extension of the balloon films are all significant. Flights of two-piece, streamlined balloons with a lower modulus carrier balloon than previously used were still slower than is desirable. Author
