Available in PDF, EPUB and Kindle. Book excerpt: The MIL-STD-1553B multiplex data bus system offers a common means of interconnecting subsystems in military aircraft avionic systems. Presently the 1553B data bus structure accommodates the control, status, and data type of signals that comprise 80 to 90 percent internal interface exchange between avionic equipment. However, as a tool for overall avionic systems integration, this system can be used to implement integrated control and display panels, various processing architecture, and provide the ability to access the total avionic systems for monitoring status, built-in test, and diagnostics. Provisions for growth and modification are an inherent part of the design. The key feature of the MIL-STD-1553B system is its flexibility. The system can be utilized in total or in part to satisfy a particular interconnectivity requirement. In effect the system interrogator manipulates the system to satisfy his interface signal exchange by implementing the type of signal routing and bus control that is best suited to his needs. This is done within the constraints of a common protocol and data bus structure. Under contract No. N62269-77-C-0236 to NADC, (April 5, 1979) AiRsearch further exploited the flexibility of the 1553A data bus by developing a multiplex aircraft intercom system that demonstrated the ability of 1553 protocol and format to accommodate audio signals for exchange between crew members and radio equipment.

Available in PDF, EPUB and Kindle. Book excerpt: Although the preliminary test results are encouraging, it must be remembered that they were taken under ideal conditions. For all testing, the microphone was positioned just brushing the test subject's lips; however, a test was run with one test subject placing the microphone approximately four millimeters from the test subject's lips. The test results showed a 50% decrease in recognition accuracy for the same conditions as those with a microphone touching lips. Although the results are preliminary, it is apparent that the signal-to-noise ratio is a key factor in recognition accuracy. Another problem arises because of the automatic gain controls (AGC) found in most aircraft intercom systems. When there is no voicing for a period of time, the AGC increases the intercom sensitivity. If the first utterance spoken is intended for the recognizer it will likely be rejected because of the distortion caused by the AGC adjusting the gain during the utterance. This is demonstrated in the test results of all test subjects. No attempt was made to set the AGC before beginning the test; as a result, 90% of the first utterances were rejected which resulted in the lowering of the accuracy score by approximately 4%. The AGC has a release time of 10 seconds and the prompts are issued every second; therefore, after the first utterance the AGC has little effect. Some side tests were performed by making an utterance before signaling the computer to begin the test, and in each case the accuracy of the first test word increased to a point comparable to the other vocabulary words.

Available in PDF, EPUB and Kindle. Book excerpt: Instrumentation interfacing frequently requires the linking of intelligent systems together, as well as requiring the link itself to be intelligent. The airborne instrumentation computer system (AICS) was developed to address this requirement. Its small size, approximately 254 by 133 by 140-mm, standard bus, and modular-board configuration give it the ability to solve instrumentation interfacing and computation problems without forcing a redesign of the entire unit. This system has been used on the F-15 aircraft digital electronic engine control (DEEC) and its follow-on engine model derivation (EMD) project, and in an OV-1C Mohawk aircraft stall-speed warning system. The AICS is presently undergoing configuration for use on an F-104 pace aircraft and on the advanced fighter technology integration (AFTI) F-111 aircraft.
