Claims16
A solid rocket propellant comprising:
- a hydroxyl-terminated polybudadiene (HTPB) binder system having a high molecular weight diol that is selected from the group consisting of 9,10-dinonyl-1,18-octadecanediol, 3,4-dihexyl-9,10-octadiol decalin, 1-octyl-2-benzyl-5,6-octadiol, 1-octyl-2-cyclohexyl-5,6-octadiol, and combinations thereof and excluding dimeryl diisocyanate (DDI).
A solid rocket propellant comprising:
- a perchlorate oxidizer;
- a fuel;
- and
- a hydroxyl-terminated binder system having a dimer diol (DD) selected from the group consisting of 9,10-dinonyl-1,18-octadecanediol, 3,4-dihexyl-9,10-octadiol decalin, 1-octyl-2-benzyl-5,6-octadiol, 1-octyl-2-cyclohexyl-5,6-octadiol, and combinations thereof.
