    The latest advances in electric and electronic aircraft technologies from the point of view of an "all-electric" aircraft are presented herein. Specifically, we describe the concept of a "more electric aircraft" (MEA), which involves removing the need for on-engine hydraulic power generation and bleed air off-takes, and the increasing use of power electronics in the starter/generation system of the main engine. Removal of the engine hydraulic pumps requires fully-operative electrical power actuators and mastery of the flight control architecture. The paper presents a general overview of the electrical power generation system and electric drives for the MEA, with special regard to the flight controls. Some discussion regarding the interconnection of nodes and safety of buses and protocols in distributed systems is also presented View full abstract»

    How the performance of wearable textile antennas is affected on the antenna bending is described herein. The authors focus on the resonance frequency fluctuation and input-match bandwidth variation due to the antenna bending. The results are given for three different antennas, namely, a conventional patch, EBG, and dual-band U-slot antennas View full abstract»

  • Theater battle management core system lessons for systems engineers

    The difficulties encountered during development of the theater battle management core system (TBMCS) provide lessons for systems engineering of large-scale, software-intensive systems. The absence of formal requirements and oversight, coupled with strong pressure for rapid deployment, caused the program to fail its first operational tests and actually delayed its deployment to the Held. The lack of measurable requirements and the need to integrate multiple third-party products and systems made it impossible to establish a system baseline and to test TBMCS in realistic conditions. Thus, significant problems manifested themselves only during official government tests. Moreover, despite nominal authority, the lead contractor had little or no control over the government-furnished elements and commercial off-the-shelf products that TBMCS was to incorporate. Experience with TBMCS leads to several conclusions. First, the more complex a system, the greater the need for rigor and discipline in engineering processes. Second, well-defined requirements are essential. Third, mandating the incorporation of specific third-party hardware or software may create severe problems for system development. Other lessons highlight the importance of open standards in a heterogeneous information technology environment and of layering with well-defined interfaces to facilitate integration and system evolution View full abstract»

    RFID technology is a popular research topic for both academia and industrial practitioners in recent years. However, most published articles focus on the technology itself and seldom discuss the implementation issues of RFID-based systems. This article sets out to fill this gap by proposing some key aspects to automate RFID-enabled systems, in particular supply chains View full abstract»

    In past years, the onboard trajectory measurements complex (OTMC) was found in flight tests of flight vehicles (FV). The quick-release small-sized complex makes registration of the information of onboard systems, definition of trajectory parameters of FV, the information synchronization of onboard systems, and trajectory parameters. OTMC is used for the solution of the whole set of different tasks on estimation of the characteristics of FV and its onboard equipment. With the help OTMC in flight tests there solved the tasks of estimation: operation and accuracy characteristics of air navigation computing systems, inertial navigational systems, integrated navigational systems; SNS receivers, landing radio engineering systems, accuracy of flights under the standard takeoff patterns and landing, take-off and landing characteristics, accuracy characteristics of radars, corrections of high-altitude, fast-track parameters, systems of early warning of ground proximity etc View full abstract»

    The results of an integrated strap-down inertial system development and tests are presented. The system includes laser gyros and accelerometers and is intended for measuring railway track angular parameters. To raise the accuracy of angles and distance measurements the inertial system is integrated with a GPS receiver and an odometer. Test results showed that BINS-N accuracy is better than the accuracy of an issued system View full abstract»
