Abstract
1. Выходное устройство двухконтурного газотурбинного двигателя, содержащее наружный корпус двигателя, корпус турбины и затурбинный обтекатель, образующие наружный канал холодного и внутренний канал горячего газа и расположенные за рабочим колесом последней ступени турбины стойки крепления корпуса турбины и затурбинного обтекателя и смеситель, отличающееся тем, что стойки крепления корпуса турбины и затурбинного обтекателя выполнены в виде полых аэродинамически профилированных стоек, а смеситель выполнен в виде кольцевого лепесткового элемента со сквозными лепестковыми каналами и чередующимися с ними лепестковыми каналами, образованными на выходных участках полых стоек, сквозные каналы сообщены с внутренним каналом горячего воздуха, а каналы, образованные на выходных участках полых стоек сообщены с наружным каналом холодного воздуха, кольцевой элемент прикреплен к затурбинному обтекателю и корпусу турбины и сопряжен с корпусом двигателя, при этом входные участки профилированных стоек крепления повернуты навстречу направлению вращения рабочего колеса последней ступени турбины на угол 20-40° к ее продольной оси, а стенки каналов и средняя линия выходных участков стоек направлены вдоль продольной оси турбины, причем число стоек определяется из выражения:b/t=1-3,где b - длина хорды стойки;t - расстояние между стойками.2. Выходное устройство по п.1, отличающееся тем, что смеситель снабжен дополнительными сквозными лепестковыми каналами, размещенными между полыми стойками и сообщенными с наружным каналом холодного воздуха.1. The output device of a dual-circuit gas turbine engine, comprising an outer engine casing, a turbine casing and a turbine cowling, forming an outer cold channel and an internal hot gas channel and located behind the turbine impeller of the last turbine stage of the turbine and turbine cowling casing mounting struts and a mixer, characterized in that the mounting posts of the turbine housing and turbine cowling are made in the form of hollow aerodynamically shaped struts, and the mixer is made in the form of ring lobes of the element with through petal channels and alternating petal channels formed at the output sections of the hollow racks, the through channels are in communication with the internal channel of hot air, and the channels formed on the output sections of the hollow racks are connected with the external channel of cold air, the annular element is attached to the turbine fairing and turbine casing and is coupled to the engine casing, while the input sections of the profiled mounting struts are turned towards the direction of rotation of the impeller of the last of the turbine stage at an angle of 20-40 ° to its longitudinal axis, and the channel walls and the middle line of the outlet sections of the racks are directed along the longitudinal axis of the turbine, and the number of racks is determined from the expression: b / t = 1-3, where b is the length of the rack chord ; t - distance between racks. 2. The output device according to claim 1, characterized in that the mixer is equipped with additional through petal channels located between the hollow racks and communicated with the external channel of cold air.
