Training interface device for dispensing stores

A training interface device electrically connected between an ejector rack cable and a dispenser cable, said training interface device for use on an FB-111 aircraft during simulated nuclear bombing flights using conventional non-nuclear practice stores whereby cockpit indications and actions are similar to flights using conventional nuclear practice stores, said training interface device comprising:

• a first relay for imitating the unlocking of a solenoid in a rack attached to a pylon of said aircraft, said first relay being activated by a station program unit in response to a computer output, said first relay having a first switch for connecting station program unit power to a dispenser for releasing stores, a second switch for connecting a weapon power line to said dispenser, and a third switch for connecting an unlocking monitor line to power, said switches closing in unison upon actuation of said first relay;
• a second relay for imitating a sensing switch in said rack for indicating stores present and away indications in the cockpit, said second relay being actuated by power from said rack cable, said second relay having a first switch for disconnecting an identification line associated with stores present, and a second switch for interrupting power to an arming monitor station program unit, said switches acting in unison upon actuation of said second relay;
• a third relay having time delay means therein for controlling indicator illumination upon stores away, said third relay being actuated by said first relay, upon activation of said third relay, a switch therein providing power on an output line during a fixed period of time;
• and
• a fourth relay having time delay means therein, said fourth relay providing power to said second relay after a fixed period of time upon actuation of said fourth relay by said third relay.
