ANALYSIS OF METHODS PROVIDING ACCURACY FOR TOOLS AND TECHNIQUES VIBRATION MEASUREMENT IN THE PROCESS OF MAINTAINING AIRWORTHINESS OF AIRCRAFT

On the basis of system approach the structure of the aviation activity areas on air transport related to monitoring and measurements of vibration parameters is presented.The technology analysis of laboratory tests of the onboard equipment control of vibration parameters is carried out. The issues related to ensuring the unity of measurements of vibration parameters are researched and summarized.While dealing with the works on metrological certification described in the article, the risks arising from aviation activity on air transport are taken into account. The certification methods of measuring channels of vibration parametersused on stands for testing GTE at the repairing of aircraft engines are developed. The methods are implemented when conducting initial and periodic certifications of test benches for twelve types of aircraft GTE in repair organizations. The reliability of the results of the conducted research due to the fact that they were carried out with the use of certified measurement equipment, included in the State register of measuring instruments. The research is conducted for a sufficiently high statistical confidence level with the boundaries 0.95. The studies have shown that running on air transport measurements of vibration parameters are metrologically secured, the unity of measurements and their traceability from the national primary reference to special measuring instruments, test equipment, and onboard controls of the aircraft is maintained.
