Metoda oceny i klasyfikacji gruntowych nawierzchni lotniskowych
W pracy przedstawiono projekt metody oceny gruntowych nawierzchni lotniskowych w aspekcie warunków współpracy kół podwozia samolotu z nawierzchnią. Zawarto podstawy teoretyczne, dostępne metody pomiarowe możliwe do zastosowania w projektowanej metodzie a także opisano projektowane rozwiązania. Przewiduje się, że przygotowywana do wdrożenia metoda może przynieść znaczne korzyści w zakresie lepszego wykorzystania licznych lotnisk trawiastych w Polsce, także w aspekcie bezpieczeństwa operacji lotniczych.
A test method for evaluation and classification of unsurfaced airfields
The study presents a project of a method for testing, evaluation and classification of unsurfaced airfields, with respect to wheel-soil interactions analysis. Basic theoretical considerations have been included in this study, together with a review of existing methods as well as instrumentation, which will be applied in the presented method. It is supposed the method to be advantageous for a better utilization of grassy, unsurfaced airfields in Poland and other EU countries, mainly through improving the safety level of airfield operations.
Evaluation of changes in fuel delivery rate by electromagnetic injectors in a common rail system during simulated operation
The objective of this study was to determine changes in fuel delivery rate by common rail system injectors during their simulated operation on a test stand. Four Bosch injectors used, among others, in Fiat 1.3 Multijet engines were tested. The injectors were operated on a test rig at room temperature for 500 hours (more than 72 million work cycles). During the test, pressure and injection frequency were changed. Changes in the operating parameters were estimated based on obtained injection characteristics and effective flow area determined thereby. The observed changes in fuel delivery rate were compared with results of the surface analysis of control valves and nozzle needles. Despite the stated lack of wear, significant changes in the dynamics of injector operation were observed, particularly at short injection times. Small pilot injections do not have to be corrected by the fuel injection control system because they do not affect the changes in torque; however, they do affect the combustion process. This creates conditions for increased emission of toxic exhaust components.
