    It is often desirable to transmit synchro data over a two-wire line or radio link. This can be done by using time division multiplex. The amplitudes are then sampled and transmitted as pulse trains representing the sine and cosine of the shaft angles of the synchro transmitters. This paper discusses various methods of producing the servo error signals from the information in the received pulse trains. View full abstract»

    The AKT-14 UNIT shown in the block diagram of Fig. 1 is the airborne portion of the AN/UKR-7 Telemeter. Information originates as electrical signals in transducers such as strain gages at a level in the order of five millivolts. These signals are amplified by individual amplifiers to about ten volts. Each of the 32 channels is electronically sampled at a rate of 750 samples per second and commutated onto a single bus. Each of these information samples, of which there are 24,000 per second, is coded into an eight-digit binary code. This code consists of eight active plus one inactive, or blank, digits. The resultant coded information is transmitted to the ground by an fm radio link or it may be recorded on magnetic tape in the aircraft. View full abstract»

  • Part III — UKR-7 telemetric data receiving set

    As performance requirements are becoming more stringent, precise measurements and study of large quantities of telemetric data are now mandatory for missile and aircraft development. Improvements in equipment design can best be accomplished by utilization and reduction of more and more raw data to properly evaluate performance characteristics during the equipment's design stages. The UKR-7 Telemetric Data Receiving Set is designed to eliminate the long delays between the time of measurement and the time at which comprehensive data is available in either plotted or tabular form by overcoming many of the problems of storing and reducing telemetered information.

    To effectively evaluate critical portions of the primary data recording, a quick-look analog recorder is utilized in the ground system. This visual presentation, readily available for inspection in real time, presents a continuous record of 750 digital points per second on all 32 channels of information in analog form accurate to plus or minus three per cent.

  • Part V — UKR-7 ground translator and programmer

    The volume of information acquired in eight minutes of a test vehicle flight has been mentioned previously as amounting to approximately 100 million bits of information. This represents over 12 million data points to an accuracy of one part in 256. If this information were punched on cards it would require a storage space of about 134 cubic feet (Fig. 1). Obviously, much of this information is of no significance to the test engineer and may be eliminated, as it occurs, by utilizing a quick-look recording and the programmed translator.

  • Part VI — PWM and FM/FM automatic data reduction with AKT-14 telemetering components

    The problem of rapidly processing and reducing large amounts of data is a prime concern of all activities involved in the testing of aircraft and guided missiles. With the ever-increasing volume of data to be handled it is apparent that reduction of the data by humans is not only extremely slow and inefficient but also very expensive in terms of time in getting test results in the hands of cognizant test engineers.

    During the question and answer period following the presentation of these papers, considerable discussion of the comparison of sampling rates in time-division telemetry systems and frequency response in frequency-division systems occurred. It is the purpose of this appendix to enumerate some of the basic differences in these two concepts and their practical application in the evaluation of the performance capabilities of telemetering systems.

    Save to Project icon | Request Permissions | Click to expandQuick Abstract | PDF file iconPDF (1347 KB)  

    The program to be described is one used in an advanced phase of the flight testing of the Digitac system, an airborne automatic control system utilizing a digital computer. The purpose of the system is summarized. The configuration of the system and some specific components are mentioned. The computer and its order coding system are described briefly. The specific program and its code are presented in detail as far as permitted. Emphasis is placed on certain aspects which are interesting or unique and may be applicable to others in this field. Simplification of the program is made by means of block diagrams. View full abstract»
