Method of tribodiagnostics of d-30KU engines/KP with the use of a microwave plasma complex: results of metrological examination and analysis of the accuracy

The article contains the results of the metrological examination and research of the accuracy indicators of a method for diagnosing aircraft gas turbine engines of the D30KU/KP family using an ultra-high-frequency plasma complex. The results of metrological examination of a complete set of regulatory documents related to the diagnostic methodology, and an analysis of the state of metrological support are provided as well. During the metrological examination, the traceability of a measuring instrument (diagnostics) – an ultrahigh-frequency plasma complex – is evaluated based on the scintillation analyzer SAM-DT-01–2. To achieve that, local verification schemes from the state primary standards of the corresponding types of measurements were built. The implementation of measures to eliminate inconsistencies identified during metrological examination allows to reduce to an acceptable level the metrological risks of adverse situations when carrying out aviation activities in industry and air transportation. In addition, the probability of occurrence of errors of the first and second kind in the technological processes of tribodiagnostics of aviation gas turbine engines is reduced when implementing a method that has passed metrological examination in real practice. At the same time, the error in determining ratings and wear indicators provides acceptable accuracy indicators and sufficient reliability in assessing the technical condition of friction units of the D-30KP/KP2/KU/KU-154 aircraft engines.

Metrological aspects of pre-flight anti-icing procedures for civil aircraft

Snow-ice deposits formed on the outer surfaces of aircrafts on the ground during parking can have a negative impact during take-off due to the deterioration of aerodynamic and flight performance, a significant and even critical decrease in lift, increased drag, blocking controls, difficulty or blocking of landing gear retraction, damage to the blades of inlet guide vanes and/or the blades of an engine compressor. To exclude the influence of snow and ice deposits, anti-icing treatment is performed, including their removal and/or protection from subsequent formation. For this purpose, special anti-icing machines (deicers), equipped with such means of instrumental control as counters of anti-icing fluid pumps, measuring scales of anti-icing fluid tanks, thermometers and pressure gauges for temperature and pressure measuring at the outlet of a spray nozzle, are used. The article deals with the metrological aspects of civil aircrafts anti-icing prior to flight.

Measurements, tests, control in the aerospace industry-status, trends, prospects

Readers are invited to review the reports and speeches of the participants of the All-Russian Conference “Measurements. Tests. Control” held from 23 to 25 October 2018 in the framework of the 15th International Exhibition of Testing and Measuring Equipment “Testing & Control” in the Crocus-Expo Moscow Exhibition Centre.

The analysis of measurements of flatness of the artificial surfaces of the runway of civil aerodrome

One of the most important characteristics of the runways with artificial turf of civil airfields is their evenness. Passengers of the mainline aircraft – both in domestic and foreign airportssubjectively assess the airfield pavements evenness by the presence or absence of shaking during the movement of the aircraft on the runway both during takeoff and landing. In units of what physical quantities, by what means and methods is measured (estimated) the evenness of aerodrome surfaces? How to ensure of the traceability of measurements from the primary national etalon of parameter to the value of the measured value. About it-this publication.

It was held in IEC “Crocus Expo” (Moscow) from 24 to 26 October in the framework of the 14th International exhibition of testing and measuring equipment Testing & Control. The review was prepared by results of work of section № 4 “Metrology and Standartisation. Metrological provision of research, testing and exploitation of aviation and space technics”.

Ensuring the uniformity of measurements of parameters of vibration during the technical operation of aircraft

In this article we are talking about how to ensure the unity of measurements of vibration parameters in the technical operation of aircraft. In air transport, the main controlled parameters of vibration in flight are vibration speed, vibration acceleration or vibration overload. They are particularly informative for aircraft with turboprop engines, as well as helicopters, which – because of the design features-the vibration is much higher than on aircraft with turbojet engines.
