16、rom the aircraft weapon stations. Its package size shall enable it to operate from one to nine stores racks. This is accomplished by the proper addition of logic modules to the basic package. These logic modules are supplied as part of the system dependent,on the number of stations required to be se

17、rved. 3.5.1.2 Form Factor - The programmer shall conform to the dimensions and requirements shown in figure 2. 3e5.1.3 Weight - The weight of the basic one-station (center) programmer shall not exceed 8.4 pounds. 3.5.1.4 Contents - The programmer shall be composed of the following: (1) Logic Power S

18、upply - The logic power supply shall be operated from the aircraft 115-v, 400-Iiz or 28-vdc line. Its output shall provide all logic level voltages required by the system. (2) Station Transfer Logic - If the selected number of stores to be released exceeds the capacity of the highest priority statio

19、n or pair of stations selected, the system shall automatically change to the next lower priority ,ctation(s) selected and continue releasing stores until the select number of stores have been released. The stores transfer information shall be obtained from inputs as follows: (This equipment shall va

20、ry as dependent on 3.5.1.1). Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-P-81361(AS) (a) Multiple Stores (2 Through 6 Rounds) - The system shall receive an identification signai (a ground) when a rack with multiple stores (2 through 6 rounds)

21、 is being carried, Each weapon station will have its own Individual line to the system in order to provide these signals. The removal of this ground, after it has been initially received, shall cause the system to change station as required by 3.5,1.4(2). (b) Fire Pulse Counters - The system shall p

22、rovide a fire pulse counter for each weapon station, If a rack is providing a multi- ple store (2 through 6 rounds) ground signal and the removal of this signal is not received by the time 6 fire pulses are counted, the fire pulse counter itself shall generate the station transfer signal, thereby ca

23、using the system to change stations to the next lowest priority station (s) selected. (c) Multiple Stores (7 or More Roundsl - The system shall receive an identification signal (a ground) when a rack with multiple etores (7 or more rounds) is being carried. Each weapon station will have its own indi

24、vidual line to the system in order to provide these signals. The removal of this ground, after it is initially received, shall cause the programmer, to change stations as required by 3.5.1.4 (2).
