for researching standby Compound system,the authors propose a new Laplace transform method which are used for deducing mathematical expression of system reliable lifetime 。The reliability function is simulated with MATLAB software and analyed,The results show that this method is not only effective but also simple and practical.

In order to solve the problem of simulation difficulty of the control and display unit (CDU) for full flight simulator, it is real significance to design the CDU. The principles and design methods are expounded about the CDU in detail. The simulation CDU is tested on full flight simulator. The results show that the simulation CDU can establish flight plan, modify flight route, and set the performance parameters. The component has correct logic, high fidelity and reliable performance. The simulation CDU can meet full flight simulator design requirements.

Reliable operation of the aircraft power distribution system is critical to the flight safety of a plane。In this paper,the reliability evaluation model of aircraft power supplying system based on Bayesian fusion is set up。 Calculating reliability indexes by using MATLAB simulation softwaer。Comparing with the traditional Bayes approach,the result shows the method is efficient。
