Abstract

1. Камера сгорания с принудительным реверсированием потока, которая содержит корпус камеры сгорания, выполненный в виде полости с изогнутой формой, подобной форме кисти руки с пальцам, согнутыми в сторону ладони и симметрично расположенными относительно ее центра; совокупность закручивающих лопаток для подачи воздуха в камеру сгорания, расположенных соответственно на внутренней стороне выхода для пламени камеры сгорания; причем совокупность лопаток включает в себя закручивающие лопатки для подачи радиального потока вторичного воздуха в камеру сгорания, расположенные на внутренней стороне конца камеры сгорания, где расположен выход для пламени.2. Камера сгорания по п. 1, в которой в середине внутреннего конца камеры сгорания предусмотрена топливная форсунка, встроенная во внутреннюю стенку камеры сгорания таким образом, что выпуск форсунки проходит сквозь внутреннюю стенку камеры сгорания, причем выходной конец камеры сгорания после смешивания воздуха и топлива является выходом для пламени.3. Камера сгорания по п. 2, в которой совокупность закручивающих лопаток дополнительно включает в себя закручивающие лопатки для подачи третичного воздуха к области горения, расположенные на внутренней стороне выхода для пламени камеры сгорания.4. Камера сгорания по любому из пп. 1-3, в которой на стороне дугообразной полости камеры сгорания в стороне от пламени расположен воздушный канал, внутри которого расположен воздушный компрессор для подачи воздуха в камеру сгорания и воздушный выход которого находится на противоположной стенке изогнутой полости камеры сгорания.1. The combustion chamber with forced reversal of the flow, which contains the housing of the combustion chamber, made in the form of a cavity with a curved shape similar to the shape of a hand with fingers bent towards the palm and symmetrically located relative to its center; a set of twisting blades for supplying air to the combustion chamber located respectively on the inner side of the outlet for the flame of the combustion chamber; moreover, the set of blades includes twisting blades for supplying a radial stream of secondary air into the combustion chamber located on the inner side of the end of the combustion chamber, where the outlet for the flame is located. The combustion chamber according to claim 1, wherein, in the middle of the inner end of the combustion chamber, a fuel nozzle is provided that is integrated in the inner wall of the combustion chamber in such a way that the nozzle exhaust passes through the inner wall of the combustion chamber, and the output end of the combustion chamber after mixing air and fuel is an output for flame. 3. The combustion chamber according to claim 2, in which the set of twisting blades further includes twisting blades for supplying tertiary air to the combustion area located on the inner side of the outlet for the flame of the combustion chamber. The combustion chamber according to any one of paragraphs. 1-3, in which on the side of the arcuate cavity of the combustion chamber, away from the flame, there is an air channel, inside of which there is an air compressor for supplying air to the combustion chamber and the air outlet of which is on the opposite wall of the curved cavity of the combustion chamber.
