FIELD: machine building.
SUBSTANCE: combustion system (3; 46; 62) at constant volume for a turbomachine comprises a plurality of combustion chambers (11–14) uniformly distributed around a longitudinal axis (AX), a compressed air supply manifold (7; 42), channel (4; 47) leads, synchronization means for synchronizing intake of compressed air into each combustion chamber (11–14) from outlet of manifold (7; 42) and discharge of gaseous combustion products from each combustion chamber (11–14) into channel (4; 47) of discharge. Collector (7; 42) for supply of compressed air passes around longitudinal axis (AX) and comprises radially oriented outlet for compressed air for supply of compressed air from compressor of turbine machine to each combustion chamber. Channel (4; 47) of lead extends around longitudinal axis (AX) and comprises radially oriented inlet for receiving gaseous combustion products from combustion chambers (11–14), as well as axially oriented outlet. Combustion chambers (11–14) are located in radial direction between collector output (7; 42) and lead channel (4; 47).
EFFECT: invention is aimed at creation of system with combustion at constant volume, which can be easily built into structure of modern turbomachine, having essentially cylindrical shape and large diameter.
