Description
技术领域technical field
本发明属于发动机润滑剂领域，特别涉及变循环喷气发动机润滑剂组合物。The invention belongs to the field of engine lubricants, in particular to a variable cycle jet engine lubricant composition.
背景技术Background technique
所谓变循环，简单而言：就是在飞机亚音速飞行时，发动机采用涡扇方式循环；而在超音速飞行时，则变涡喷方式循环。从发动机设计理念可知：对于持续高马赫数飞行时，需要高单位推力的涡喷循环。若在低马赫数和长距离飞行时，就需要低油耗的涡扇循环。而当兼有高马赫数飞行和低马赫数飞行或存在多设计点要求时，问题就出现了。单为任务的某一部分设计循环在飞行包线其他地方的性能就差。当燃油消耗几乎均分在高马赫数和低马赫数飞行混合任务中，或必须在多工况下工作时，变循环发动机(VCE)就显示出巨大的优势。原理看似简单，但从设计到工艺，到材料，却处处难点。变循环技术的核心是改变发动机的涵道比。The so-called variable cycle, in simple terms: when the aircraft flies at subsonic speed, the engine uses the turbofan cycle; when it flies at supersonic speed, the turbojet cycle is used. It can be seen from the engine design concept that for continuous high Mach number flight, a turbojet cycle with high unit thrust is required. When flying at low Mach numbers and long distances, a turbofan cycle with low fuel consumption is required. Problems arise when there is both high Mach and low Mach flight or when there are multiple design point requirements. Designing a cycle for one part of the mission alone will perform poorly elsewhere in the flight envelope. Variable cycle engines (VCE) show great advantages when fuel consumption is almost evenly split in high Mach and low Mach flight mixed missions, or when multiple operating conditions are required. The principle seems simple, but there are difficulties everywhere from design to craftsmanship to materials. The core of variable cycle technology is to change the bypass ratio of the engine.
变循环喷气发动机是通过改变发动机一些部件的几何形状、尺寸或位置来改变其热力循环的燃气涡轮发动机。利用变循环改变发动机循环参数，例如：增压比、涡轮前温度、空气流量和涵道比，可以使发动机在各种飞行和工作状态下都具有良好的性能。与此同时，变循环发动机能以多种模式(包括涡轮模式、涡轮风扇模式和冲压模式等)工作。因此，在亚音速、跨音速、高音速和超高音速状态下都具有良好的性能。A variable cycle jet engine is a gas turbine engine whose thermodynamic cycle is changed by changing the geometry, size or position of some parts of the engine. Using variable cycle to change the engine cycle parameters, such as: boost ratio, temperature before the turbine, air flow and bypass ratio, can make the engine have good performance in various flight and working conditions. At the same time, the variable cycle engine can work in multiple modes (including turbo mode, turbo fan mode and ram jet mode, etc.). Therefore, it has good performance in subsonic, transonic, hypersonic and hypersonic conditions.
对于变循环发动机(VCE)的实现还需要解决许多关键技术，例如变循环发动机(VCE)性能仿真，CDFS(核心驱动风扇级)设计，可调涡轮转向器，可调面积涵道引射器和多变量控制系统等。而变循环发动机(VCE)的控制变量明显多于常规发动机的控制变量。For the realization of variable cycle engine (VCE), many key technologies need to be solved, such as variable cycle engine (VCE) performance simulation, CDFS (core drive fan stage) design, adjustable turbine steering, adjustable area duct ejector and Multi-variable control system, etc. The control variables of the variable cycle engine (VCE) are obviously more than those of the conventional engine.
