Optic fiber payout test apparatus having a projectile track system with dual rails

摘要

An optic fiber payout test system and apparatus is disclosed which is adapted for simulating the payout of fiber at high speeds. This optic fiber payout test apparatus is comprised of a projectile, a source of fiber attached to the projectile, and a pneumatic propulsion system to propel the projectile and initiate the payout of the fiber. The fiber payout test apparatus further comprises a projectile track system as well as a braking system which allows the projectile to be used safely within a laboratory environment. The optic fiber payout test apparatus also provides a means for testing the payout of fiber optic cable in a manner that simulates the high rate of speed and high accelerations encountered during free flight. This capability is important for the development of launched fiber optic guided weapons systems and in particular, air launched optic guided weapons systems.
