Abstract
Description
technical field
[0001] The invention relates to the technical field of aerodynamics, in particular to a turbine engine. Background technique
[0002] At present, high thrust-to-weight ratio is still an important performance index pursued by aviation gas turbine engines. There are two main ways to increase thrust-to-weight ratio: one is to reduce weight; the other is to increase thrust. Regarding the first point, under the existing material and technological level conditions, in order to ensure the strength and life requirements, the space for weight reduction is very limited. For the second point, the main ways to achieve it are to increase the flow rate and increase the engine temperature rise level. Since the size of the inlet section is restricted by the aircraft, the flow rate cannot be increased arbitrarily. Therefore, in a short period of time, increasing the thrust can only be considered from the perspective of increasing the temperature rise ratio of the engine. Fo...
