在分析滑油系统部附件的基础上，根据部附件特性单调变化的特点，提出了"平衡计算"的概念，应用向量运算方法和多种插值算法取代传统的迭代算法来构造航空发动机滑油系统稳态模型算法的思路和方法，并用该算法编制程序对发动机在海平面最大状态下滑油系统性能参数进行了验算。

The V12 TDI crankcase is made from gray cast iron with vermicular graphite - a high-tech material referred to as GJV-450 that is already used on the V6 and V8 TDI engines.

曲轴箱的V12 TDI发动机是由与蠕墨灰铸铁-高科技的材料被称为GJV - 450是已经在V6和V8 TDI发动机使用。

With the aim of control pneumatic stability fault and ensure the safety and function of aero-engine,The method To survey and change The two pneumatic stability faults include speed lost and pant vibratility of aero-engine has been an important researchful subject matter.

如何对航空发动机失速和喘振这两类气动失稳进行测量、变换，以便对气动失稳进行控制，确保发动机安全和性能是当前国内外航空界的一项重要研究内容。

The water/metal fuel motor system configuration is based on a numerical simulation of combustion.

水反应金属燃料发动机[1]是一种全新概念的水下高能量密度推进系统，其工作原理为：雷外海水在速度头作用下进入燃烧室，与燃烧室中以一定形态存在的金属燃料发生强烈放热反应，产生的热量使未参与反应的海水受热蒸发，混合高压气体通过发动机喷管膨胀做功产生推力，从而推动水下航行

With the improvement of the structural complication and strength index of the engine structure, during the work process, the bending-shaft produce bent and torsion because of the action of periodicity variational air pressure, inertia pressure evocabled by the to-and-fro and whirligig motion and torque, therefore, engine bending-shaft must be provided with the preferable fatigue intensity and the structure rigidity through making use of the material of high intensity and the reasonable forging technique.

随着发动机结构的复杂化和强化指标的不断提高，曲轴在工作过程中，由于受到周期性变化的气压力、往复和旋转运动引起的惯性力以及弯矩、扭矩的共同作用，既产生弯曲又出现扭转，这就要求发动机曲轴具有高的疲劳强度和结构刚度。
