Information × Registration Number 0213U003797, 0112U004759 , R & D reports Title Development, making and realization of preliminary tests of metering pump-device of НД450С for the engine of АИ-450С popup.stage_title Head Pavlyuk Yevgen, Registration Date 15-03-2013 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-450С. ГМЧ САУ engine of АИ-450С 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.5481 Product Description popup.authors Вдовченко Володимир Валентинович popup.nrat_date 2020-04-02 Close
