Information × Registration Number 0217U001742, 0114U006426 , R & D reports Title Development, making and preliminary tests operation of metering pump of НД450МТ for the engine of АИ-450М popup.stage_title Head Pavlyuk Yevgen, Registration Date 26-04-2017 Organization State enterprise "Kharkov Aggregate Design Bureau" popup.description2 The aim of development is creation of hydromechanical part of the system of automatic control (ГМЧ САУ) of engine of АИ-450М. ГМЧ САУ engine of АИ-450М must provide implementation of next functions: - an increase of pressure of fuel is in the pumping stage of metering pump-device; - an increase of pressure of fuel is in the basic stage of metering pump-device; - filtration of the fuel tricked into to the basic stage of metering pump-device; - delivery of signal about the obstruction of fuel filter; - cross-over of fuel by a fuel filter at his obstruction; - fuel feed control to the starting jets; - fuel feed control to the jets; - control flow of fuel through sprayers on the commands of electronic regulator on the next modes of operations of engine: - /start; - steady-state modes; - variable modes; - cold scrolling; - false start; - preservation; - depreservation/; - limitation of minimum expense of fuel; - limitation of maximal expense of fuel; - delivery of signal about position of batching element; - passing to the backup system of automatic control by the expense of fuel through sprayers (metering pump-device); - maintenance of expense of fuel through sprayers on the commands of metering pump-device depending on position of lever of task of expense of fuel; - correction of expense of fuel through sprayers; - change of expense of fuel through sprayers at moving of lever of task of expense of fuel on a temporal law; - engine cutoff. ГМЧ САУ must have a module construction allowing to change the volume of executable functions and restore a capacity replacement of the separate modules. On the fifth final stage the interdepartmental tests of pre-production model of metering pump-device of НД450МТ are conducted with confirmation of resource 1000 hours, designer documentation is corrected on results tests, documentation the letter of "О1" is appropriated Product Description popup.authors Петренко Павло Миколайович popup.nrat_date 2020-04-02 Close
