Abstract
The present invention deals with a turboreactor comprising at least a precombustion chamber, a combustion chamber, means for directing combustion gases from the precombustion chamber into the combustion chamber, an air compressor, and means for dividing the air flow from the air compressor while guiding it in the combustion chamber. The turboreactor comprises advantageously a contrarotating stator. The invention relates also to a process in which the blades are heated and pushed in a thermoplastic layer of the body of the rotor and/or stator.
Claims14
A turbojet engine comprising
- a compressor sucking and compressing air in order to form at least one main stream of compressed air,
- at least one combustion chamber,
- at least one turbine receiving the combustion gases from the at least one combustion chamber,
- at least one precombustion chamber including at least means for supplying an oxidizing medium and a fuel therein,
- means for directing the combustion gases from the precombustion chamber into the combustion chamber,
- means for directing at least a portion of the main stream of compressed air from the compressor in the combustion chamber, said means having a series of passages dividing the main stream into a series of compressed air flows flowing in the combustion chamber, in which said passages are designed with respect to the means directing the combustion gases from the precombustion chamber to the combustion chamber so that each means directing the combustion gases from the precombustion chamber into the combustion is located between two passages dividing the main stream of compressed air and so that the compressed air flows issued from the division of the main air flow creates a depression in the combustion chamber with respect to the precombustion chamber and a suction of the combustion gases from the precombustion chamber into the combustion chamber.
