CIWS Cam Pin Actuator

Problem: Failure of a small part in the ammunition handling system can lead to a complete catastrophic system failure. This failure mode is a leading contributor to the system unreliability.

Solution: MTTC, working with the Navy and equipment manufacturer (General Dynamics), will analyze the root cause, redesign the part and produce several concept parts for system tests.

Benefits

Estimated Navy Cost Avoidance:

Minimum annual:       $224 K

Minimum 15 Year:   $3,360 K

Fleet Impact: It is estimated that correction of this problem will prevent at least 10 system failures per year. Each failure requires a large number of parts and expenditure time to correct.

Status: Ongoing

The design effort and drawings for the bushing, shaft and scoop disc modifications are complete. The structural analyses of both existing and new designs are complete. Two sets of prototype parts are being fabricated. Initial testing will be conducted at the test range at General Dynamics, Burlington. Delivery to the Navy is expected in June, 2002.

Applications:

320 Phalanx CIWS systems in U.S.Navy Foreign Military Sales Customers.
