The invention relates to a combustion chamber, an engine and a helicopter, the combustion chamber comprises a cartridge receiver inner shell and a cartridge receiver outer shell, the cartridge receiver inner shell and the cartridge receiver outer shell are mutually connected to form a heat insulation cavity, a mounting cavity is formed in the cartridge receiver inner shell, a flame tube is mounted in the mounting cavity, an evaporation tube is mounted on the flame tube, and the evaporation tube is connected with the heat insulation cavity. The evaporation pipe comprises a collecting pipe and an evaporation spray pipe which are connected with each other, a nozzle seat and an oil supply pipeline are installed in the heat insulation cavity, one end of the nozzle seat is communicated with the oil supply pipeline, the other end of the nozzle seat is connected with a nozzle, the end, away from the nozzle seat, of the nozzle is communicated with the collecting pipe, and the collecting pipe is communicated with the evaporation spray pipe. The evaporation spray pipe is located in the annular cavity of the flame tube. The whole combustion chamber is sealed, external particulate matter and corrosive substances can be prevented from invading, and the fuel oil pipeline and the nozzle seat are prevented from being impacted by external sand dust and corroded by the corrosive substances.
