现代航空发动机的自动测试系统(上)

An Automated Test System for Modern Aero-Engine (Part 1)

航空发动机在高温、高压、高转速与高载荷等极其复杂和苛刻的环境下工作,为了保证安全可靠地工作,在其研制阶段除需要经过详细的设计计算外,其部件和整机部必须经过严格的地面试验,包括高空模拟试验。为此需要建立专门的试车台,配备各种测量与控制设备以便检验和确保性能达到设计指标,操纵性与耐久性达到规定要求。此外还需要进行结构完整性试验和环境试验等。当发动机投入使用后,为确保正常运行和保持完好状态,

The paper presents the AEDC's aero-engine system test facility ( ASTF), automated test system and test approach for the F119 engine . The ASTF mainly consists of the test article , test stand and test instrumentation system . The paper will be published by two parts. The part 1 introduces the ASTF and Next part will describe F119 automated test system .
