BSU-86/B Bomb Fin |
(fig. 1-25) attaches to the bomb body by eight
setscrews. It is a self-contained unit that consists of a
stabilizer assembly (canister housing) with four fixed
fins (X-shaped) and a lanyard assembly (fig. 1-25,
views A and B). The four fixed fins provide low-drag
aerodynamic stability. The wedges installed on the
trailing edges provide stabilizing spin during a
low-drag and high-drag release. When stored in its
original shipping/storage container, its shelf life is 10
years.
