Abstract

—The paper describes the results of the first step of the research team of the Department of Theory of Aircraft Engines to modernize the working process of a cooled axial two-stage high pressure turbine. The paper describes 2 numerical models of the turbine. The first one is with a small number of finite volumes. It is relatively accurate, but requires moderate computer resources to obtain results. The application of this model is planned for the optimisation process. The second one is with a large number of finite volumes. It is expected to have lower error rate and high computational cost. It will be used by the authors for verification calculations to check the found optimal variants and to choose the final variant. The created numerical models are verified by the available experimental data. The paper substantiates the choice of the number of finite volumes in the annular section of the blade passage, as well as their distribution along the blade height. It is shown that the integral parameters of the turbine obtained in the calculation lie in the scatter field of experimental data.

现代民航GTE两级HPT数值模型验证

-本文介绍了航空发动机理论系课程组对轴向冷却两级高压涡轮工作过程进行现代化改造的第一步研究成果。本文介绍了水轮机的两种数值模型。第一种是有限体积的情况。它是相对准确的，但需要适度的计算机资源来获得结果。在优化过程中规划了该模型的应用。第二种是有大量有限体积的情况。期望具有较低的错误率和较高的计算成本。它将被作者用于验证计算，以检查发现的最优变体并选择最终变体。所建立的数值模型得到了实验数据的验证。研究了叶片流道环形段有限体积数量的选择及其沿叶片高度的分布。结果表明，计算得到的涡轮整体参数位于实验数据的散射场中。
