封闭式涡轮轴发动机试验室的设计考虑

[中文适用范围]： 本SAE航空信息报告由航空工业和政府机构广泛人员编制，旨在为设计新型或升级的涡轮轴发动机试验设施的个人和组织提供最新技术信息。本文件也适用于使用测功机作为负载吸收装置的涡轮螺旋桨发动机的测试，因为其基本测试方式与涡轮轴发动机相同。关于螺旋桨涡轮风扇试验设施的设计考虑，参见2.1.7。 1.1 目的 a. 为涡轮轴发动机的地面封闭式试验设施设计提供指导； b. 讨论影响被测发动机运行、性能、精度和稳定性的主要试验台发动机负载吸收装置的物理、气动和声学特性； c. 考虑声学和环境影响及其控制方法。 [外文原描述]： This SAE Aerospace Information Report (AIR) developed by a broad cross section of personnel from the aviation industry and government agencies is offered to provide state-of-the-art information for the use of individuals and organizations designing new or upgraded turboshaft engine test facilities. This document is also applicable to turboprop engines tested with a dynamometer as load absorption device, as they are basically tested as turboshaft engines. For propeller-equipped turbofan testing facilities design considerations, see 2.1.7.
