• Advanced Instrumentation for Advanced Aircraft

      Penharlow, David; Aydin Vector Division (International Foundation for Telemetering, 1988-10)
      Advanced aircraft require sophisticated instrumentation system designs. New concepts incorporated in distributed data acquisition systems allow the flight test instrumentation engineer a selection of hardware with reduced size and weight, which requires minimal vehicle wiring between components. Improved accuracy and resolution are additional benefits of the distributed data acquisition systems described in this paper. These systems, currently being delivered by Aydin Vector for several major flight test programs, allow conditioning and encoding to be achieved near the sensors through a variety of remote units. The remote units for these applications differ as the measurement requirements and test program requirements differ. We will examine the distributed data acquisition systems used for several test vehicles and briefly describe vehicle for test program requirements which led to unique designs. The systems described for these applications are variations of the Aydin Vector ADAS-7000 System. The common element for these systems is the PMU-700 Programmable Master Encoder.
    • High Shock, Wideband, Miniature, Air Borne FM/FM Telemetry System

      Aydin Vector Division has received an order from Saab Missiles AB, Sweden, to develop an airborne, high shock, wideband FM/FM telemetry system. During 1985 (within a period of eight months) three such systems (FMT-780) were built and shipped to customer after successful testing in the plant. The testing included acceptance and qualification. Later on, the three systems were exposed to high shock testing/firing in Sweden. This paper describes the specifications of the system, the design approach that was used in order to meet these specifications, the systems conceptual mechanical and electrical structure, the packaging technique and some of the test results. As a result of the success of the program, Saab Missiles AB, awarded Aydin Vector Division with an additional order for sixteen, computer based, specially designed, miniature PCM/FM airborne telemetry systems. A paper describing these systems and the overall program is going to be published within the next two years.
    • High Speed Data Acquisition Systems

      Talmadge, Richard D.; Radmand, Mansour; Wright-Patterson Air Force Base; Aydin Vector Division (International Foundation for Telemetering, 1988-10)
      Air Force systems testing today requires that more and more data be acquired to a higher degree of accuracy and in fewer flights. This necessitates a new approach to dynamic data acquisition system design. In the past data acquisition organizations used either direct or FM recording techniques of one sort or another to acquire data for post test processing. This paper will outline the direction that this organization is taking to reduce the size of the installed system as well as the time and money required to maintain the system during the testing process. The system discussed provides a capability to acquire both static (DC) data and dynamic data up to 10,000 Hertz and has a dynamic range in excess of 120 dB.
    • RF Hybrid Linear Amplifier Using Diamond Heat Sink

      Karabudak, Nafiz; Aydin Vector Division (International Foundation for Telemetering, 1988-10)
      This paper will address the applications and methods used for a high power output RF linear small signal amplifier using diamond heat sink. Comparison and the benefits of using diamond heat spreaders will be reviewed. Agrowing number of researchers, engineers and scientists are looking into the applications of diamond's unique properties such as physical, electrical and optical.
