An aero-engine can be regarded as a subsystem of the aircraft system. It is obvious that engine performances, weight and dimensions have a strong effect on the aircraft flight performances. For a given flight mission, the optimal engine scheme must be able to meet the flight requirements with the greatest possibility. From the viewpoint of system engineering, a method for integrated selection of the optimal engine cycle parameters and the control scheme is proposed, which takes the matching and interaction between...

An aero-engine can be regarded as a subsystem of the aircraft system. It is obvious that engine performances, weight and dimensions have a strong effect on the aircraft flight performances. For a given flight mission, the optimal engine scheme must be able to meet the flight requirements with the greatest possibility. From the viewpoint of system engineering, a method for integrated selection of the optimal engine cycle parameters and the control scheme is proposed, which takes the matching and interaction between the engine and the aircraft. A rapid method for predicting turbojet or turbofan engine off-design performances was adopted and an empirical formula estimating the engine weight was developed.An optimization of an augmented engine scheme meeting the requirements of a modification has been accomplished as an example. The results show that the optimum cycle parameters and the control scheme are quite different if the mission, the requirements of modification or the technical constraints are varied. Therefore, the integrated selection of engine cycle parameters is of great importance.

航空发动机是飞机的动力装置,它的性能、重量、尺寸都对飞机性能有显著影响。本文从系统工程的观点出发,综合考虑飞机、发动机性能的相互影响和匹配,提出了以最好地满足飞机飞行任务为目标,选择发动机最佳循环参数和调节计划的一体化方法。 本文的应用实例是歼击机动力改型时优选加力发动机的最佳设计方案。计算结果表明:飞机飞行任务不同、改型要求不同、约束条件不同,发动机最佳方案的类型、循环参数和调节计划也完全不同。因此,一体化选择方法具有重要实际意义。

A new problem that a hydraulic machine will suddenly lose load and cause harmful vibration when punching is being studied in many countries Although some methods have been found to reduce the vibration, it is still very important to make a theoretical analysis and experimental research.

液压机冲裁时突然失荷而造成的有害振动,是当前国内外研究的新课题,目前已初步找到了一些方法来减少振动,但与此相关的理论分析和试验研究则尤为重要。 本文采用了与其不同的观点,着重对冲裁时液压机的动力过程做了理论分析,建立了力学模型,导出计算公式,提供了计算实例并与试验数据作了对比,证实了计算公式是基本符合实际的。

The fluid torpue converters have the egual output characteristic,It is very ideal for us to want to make full use of power output of machine. Some working machines, however, are wanted to have the characteristic as mentioned above only in overload, and when the outrer load drops down to the specified load, the revoluti on of the machines must be unvarying. this means that it isreguareed that the machines are provided with 'the dynamic charateristie of The excavator'.In this rtfiele authors advanced how to get...

液力变矩器具有接近等功率的输出特性,这对于希望充分利用输出功率的机械是非常理想的。但有些工作机械仅希望在超负荷时具有上述特性,而在负荷低于额定值时机械的工作转速应基本不变,即要求所谓“挖土机动力特性”。本文挺出了使液力变矩器获得这一特性的机构方案,并讨论了有关特性。
