摘 要:涡轮基组合循环(TBCC)发动机,是高超声速巡航导弹、远程高速察打飞机和空天飞行器等未来航空武器系统的理想推进装置。TBCC只有匹配高速(Ma2~4)涡轮发动机技术,才能实现远程高速航空武器系统的技战术指标。高推重比、低耗油率、高温部件的长寿命和耐久性,是高速涡轮发动机的关键技术指标。从上世纪80年代末起,美欧在提高级负荷、减重、减少泄漏、提高温度、减少冷气量和延长高温部件寿命等技术领域,开展了广泛而深入的技术开发与验证。GOTChA技术开发流程是攻克这些技术难关的有效方法。Turbine based combined cycle (TBCC) engines are ideal propulsion systems for future aero ar-mament systems such as hypersonic cruise missiles, long-range and high speed reconnaissance/strike air-crafts and aerospace vehicles. The tactical targets of long-range and high speed aero armament systems could be realized no other than TBCC with high speed turbine engine is equipped. The crucial technical in-dexes of high speed turbine engines are high thrust-to-weight ratio, low specific fuel consumption, long life and durability of hot section components. Broad research and development at those interrelated areas was introduced in occident since 1980s. The technologies were developed such as light weight innovation struc-tures, high component efficiencies at hot environments, high temperature capability and light weight materi-als, and very effective cooling. The GOTChA process is an effective method to answer these technology challenges.
