Knysh V. Invariant frequency capacitive converters of a level for the systems of monitoring and control in a flying vehicle

Object of research: measuring process conversion of a level. The purpose of research: development primary con-verters of a fuel level, which are used in the fuel monitor-ing system and control balancing of flight vehicles, direc-tional on increase of their stability and controllability. Research techniques and instrumentation: radiowave and capacitance methods of level measurement dielectric liq-uids; theory of electromagnetic systems with distributed and concentrated parameters; theory of invariance Petrov's; theory of electromagnetic field. Theoretical and practical results: frequency capacitance method of conver-sion fuel level is designed. The models of invariant capaci-tance primary converters fuel level are synthesized. The frequency capacitance converter fuel level and invariant primary converters of a level with capacitance transducers are designed. Novelty: Frequency capacitive method of conversion fuel level based on long lines with a capaci-tance load, which allows to increase accuracy of conver-sion at the expense decreasing nonlinearity of distribution electrical field are developed. Have received further de-velopment the theory of compensation external actions based on used harmonics and operational modes of a long line. A degree of implantation: Kharkov state air industrial firm, educational process NAU "KhАІ" & "Alkon" enter-prises. Field of usage: processes of the supervision, moni-toring and control distribution of dielectric substances.
