Assignee:

Alliant Techsystems Inc. - Minneapolis MN

International Classification:

F42C 15/00

US Classification:

102221

Abstract:

A safe and arm device includes a booster base assembly having a booster base housing and a barrier. The booster base housing includes a shaft port extending substantially in line with a longitudinal axis, at least three initiator ports disposed about the axis, and a matching number of explosive transfer paths in respective communication with the at least three initiator ports. The barrier includes a matching number of fire-train transfer ports and a drive shaft. The drive shaft of the barrier is coupled within the shaft port of the booster base housing allowing the barrier to be selectively rotationally positioned about the axis into at least one of a safe position and an arm and fire position, allowing the fire-train transfer ports to be substantially aligned with the explosive transfer paths when the barrier is positioned in the arm and fire position. A booster basket assembly is also provided.

US Classification:

701 3

Abstract:

Embodiments include a flight safety assembly onboard an aerial vehicle, which includes a first sensor configured to sense first information related to flight of the aerial vehicle and a second sensor configured to sense second information related to the flight of the aerial vehicle. A sensor input is adapted to receive third information related to the flight of the aerial vehicle. A processor is operably coupled to the first sensor, the second sensor, and the sensor input. The processor is configured to determine three independent instantaneous impact points for the aerial vehicle by independently analyzing each of the first information, the second information and the third information. The processor is also configured to generate three independent onboard flight termination indicators for each of the three independent instantaneous impact points that intersects with a region to be protected.
