Embodiment Construction

[0020] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0021] The invention provides a uniform method for the engine outlet temperature field. like figure 1 and figure 2 As shown, the uniform method includes step S1 and step S2, step S1: detect the circumferential outlet temperature of the engine 10, determine the outlet temperature field high temperature region 11 and the outlet temperature field low temperature region 12 of the engine 10 according to the detection results; step S2: place the The positions of the first fuel nozzle 20 in the high temperature zone 11 of the outlet temperature field and the second fuel nozzle 30 in the low temperature zone 12 of the outlet temperature field are reversed. Research and analysis show that the performance of the flame tube and the fuel nozzle of the engine...

Abstract

The invention discloses a uniformization method of an outlet temperature field of an engine. The uniformization method comprises the following steps: S1, measuring the outlet temperature of the periphery of the engine and determining a high temperature zone of the outlet temperature field of the engine and a lower temperature zone of the outlet temperature field of the engine according to the measured result; S2, swapping a first fuel nozzle in the high temperature zone of the outlet temperature field and a second fuel nozzle in the low temperature zone of the outlet temperature field. As proven through research and analysis, the performances of a flame barrel and fuel nozzles of the engine have a certain impact on the outlet temperature field of the engine, when the outlet temperature field of the engine is not uniform due to a non-uniform air inlet amount of an air hole of a flame barrel outer ring, by swapping the first fuel nozzle in the high temperature zone of the outlet temperature field and the second fuel nozzle in the low temperature zone of the outlet temperature field, the temperature condition of the outlet temperature field of the engine can be effectively and rapidly improved, the uniformity of the outlet temperature field of the engine can be improved and the output efficiency and delivery progress of a product are improved.

Description

technical field [0001] The invention relates to the technical field of engine equipment, and more specifically, to a method for uniforming the engine outlet temperature field. Background technique [0002] When an engine (such as a turboshaft aerospace engine) is running, the inside of the engine has the characteristics of high temperature and high pressure. When the internal temperature field of the engine is not uniform, it will lead to uneven heating of parts, which will cause the parts to generate twisting force, and even cause parts to break in severe cases. Once the parts break and break into the flow channel, it is easy to damage the blades, which will cause the engine to malfunction, seriously affecting the safety of the engine and the use of equipment. [0003] Therefore, an engine outlet temperature field test is required before the engine leaves the factory. Research and experiments have shown that unqualified products account for more than 25% of the total when...
