DIFFUSION CELL OF TURBOJET ENGINE AND TURBOJET ENGINE Russian patent published in 2009 - IPC F01D9/02 F04D29/54 F23R3/04 

FIELD: motors and pumps.

SUBSTANCE: diffusion cell of turbojet engine is located between compressor and combustion chamber, is implemented independent from compressor and fixed to outer shell of combustion chamber by means of only one suspension member. Suspension member passes between outer shell and external longitudinal wall of diffusion cell and is formed by the first and the second walls in the form of truncated cone. The first wall in the form of truncated cone passes from outer longitudinal wall of diffusion cell in the direction of combustion chamber. The second wall in the form of truncated cone is affixed to the first wall in the form of truncated cone and passes to compressor between the first wall in the form of truncated cone and outer shell of combustion chamber. The other invention of group relates to turbojet engine, which contains compressor, combustion chamber, specified higher the diffusion cell and cross wall, installed between compressor's stator and outer shell for formation of annular space. Cross wall projects downwards the flow around entrance length of diffusion cell, and specified two walls in the form of truncated cone of suspension member is surrounded projecting downwards by flow part of cross wall.

EFFECT: inventions provide simplification and cost cutting of diffusion cell fixation in turbojet engine.
