Description
Предлагаемое устройство иредназначено л,л отбора гор чих газов, выход н1Их из сопла реактивиого двигател , при проведении испытаний реактивных двигателей, наиример аниационных.The proposed device is intended for l and l of the extraction of hot gases, the release of n1Iih from a jet engine nozzle, when conducting tests of jet engines, and naimer animation.
Устройство выполнено с перепускной трубой , на одном из концов которой смонтирован насадок, а на другом конце регулировочный вентиль и имеюи11ИЙ возможность поворота патрубок.The device is made with a bypass pipe, at one end of which a nozzle is mounted, and at the other end there is a control valve and it has the possibility of turning the nozzle.
Пасадок выполнен в виде конуса с продольными гцел ми, расположенными на его тюверхиости.The pasadas are made in the form of a cone with longitudinal helium located on its tyuverhei.
Па фиг. 1 схематично представлено предлагаемое устройство; на фиг. 2 - разрез по Л-А на фиг. 1.Pa figs. 1 schematically shows the proposed device; in fig. 2 is a section along L-A in FIG. one.
Устройство дл отбора гор чих газов, выход щих из сопла реактивного испытуемого дв1игател /, выполнено с перепускной трубой 2, на одном из концов которой смонтирован выхлопной насадок 3, а на другом регулировочный вентиль 4 с электроириводом и заборный поворотпый патрубок 5. Патрубок при помощи мехаиизма поворота 6 может вводитьс В струю гор чих газов испытуемого двигател .The device for sampling hot gases coming out of the nozzle of the test jet engine / is made with an overflow pipe 2, on one end of which an exhaust nozzle 3 is mounted, and on the other an adjusting valve 4 with electric winding and a suction rotary nozzle 5. The branch pipe with the help of mechanical mechanism rotation 6 may be introduced into the jet of hot gases of the engine under test.
ческой трубы 7 и коиической трубы 8 с расиоложеппыми па ее иоверхности продольными щел ми, протпв которых приварены щелевые патрубки 9.a pipe 7 and a coic pipe 8 with a riser-tight pa and its surfaces with longitudinal slots, which are welded with slotted nozzles 9.
Устройство включает также смесительную трубу 10, служащую дл нредупреждени иопадани механических частиЦ в испытуемый двигатель.The device also includes a mixing tube 10 serving to prevent the mechanical parts from being introduced into the engine under test.
Работает устройство следующим образом.The device works as follows.
После запуска двигател и выхода его на заданный режи. работы нлавиЬ вводитс заборный поворотный патрубок 5 при помощи механизма поворота 6 в струю гор чих газов до положепи , обеспечивающего необходимую температуру газо-воздущной смеси на входе в двнгатель, точна регулировка которой производитс вентилем 4.After starting the engine and its exit to a given mode. In operation, the intake swivel nozzle 5 is inserted by means of a turning mechanism 6 into a jet of hot gases until the position ensures the required temperature of the gas-air mixture at the inlet to the valve, which is precisely adjusted by valve 4.
Вместе с гор чими газами ;в заборный поворотный патрубок 5 иодсасываетс окружаюnuni воздух, и полученна газо-воздущна смесь через вентиль 4 и перепускную трубу 2 поступает в насадок 3, а затем через продольные щели и патрубки 9 в смес1ггельную трубу 10 вместе с окружающнм эжектируемымTogether with hot gases, air is drawn into the intake swivel nozzle 5 and the gas obtained through the valve 4 and the bypass pipe 2 enters the nozzles 3, and then through the longitudinal slots and nozzles 9 into the mixing pipe 10 together with the surrounding ejector
воздухо.м.air m
В слгесительной трубе происходит окончательное перемешивание газо-воздущной смеси с основной массой эжектируемого воздуха и выравнивание нол темиератур на входе вThe final mixing of the gas-air mixture with the ground mass of the ejected air takes place in the slug tube and the zero temperature at the inlet
