Abstract
This paper outlines a study of the safe assurance for safe management and safe assurance for Reliability in aviation project. The study presents as processes being closed-loop in nature. Comprehensive studies were made in connection with the general and practical ways of the safe management to deal with design of aviation making system. Trial and manufacture safe systems analysis had been carried out. The aviation project whole security must share in each design and the manufacture link.
Keywords: Safe Control, Reliability, Aviation Project
The aviation is a kind of flight activity mankind to make use of what apparatus fly off the ground in the Earth atmosphere. It differ from general of driving of mobile apparatus is in the ground. It must have the high degrees dependable.
Aviation product the quantity directly relate to the life safety of the flight personnel or travelers. At the same time, term that aviation fly want ratio to exercise in the ground to strictly get much. It not only want the every kind of and bad work environment of high, high speed, heat, high and cold etc. of orientation, but also want to bear every kind of and complicated carry to go to complete the pre-arranged action.
A very small component malfunctions or undertakes to manufacture the oversight, all possibly creates the disastrous accident sometimes in the aircraft system. And it can bring the huge economic loss, pays the extremely painful price. An aircraft is composed by organism, the engine; each kind of board installation and so on. From the produce, it includes: Stages advanced research, design, trial manufacturing, production, post-sale technical service and so on. In order to guarantee the general equipment department the complete machine arrives the stipulation by the thousands spare part the reliability and the life target in airplane, we need each aspect, each stage in entire process unreliability. In other words, the overall safe assurance is assigns in each link. The thrifty safe management system may be simplified shall be structured and adapted to the activities and size of the particular organization.
1. The safe assurance in trial stage
The aircraft trial manufacturing is the dynamic process which changes unceasingly, must carry on many revisions and the reexamination from the project concept demonstration to the design finalization before.
For the complete machine with various systems between coordination and the match, the model chief design engineer and the chief Quantity manager leads each system the safe guarantee system. According to the aircraft characteristics technical specification request, they must use the accuracy which the strict verification standard selects to guarantee the aircraft system design reasonably reliable.
They divide the aircraft spare part into the key, the heavy important document and general, after rests on their function and the expiration the influence to the aircraft security. They may carry out the reliability design in the classified foundation. They consider the reliability when the use and summary similar components breakdown rule, and adopts the elimination breakdown the measure when the design. Such result both is advantageous to the guarantee product quality, and is advantageous for the inspection design proposal efficiency.
They also must carry on the system appraisal and the quality reexamination after detailed design. Then they experiment the right design work of possibility, that main mission imitate to experiment in the ground. This work can insure accuracy to design the principle, load the ability with compute method. It can exterminate to design the mistake at the diagram paper to experiment the stage with ground. Finally, according to conclusion of the total experiment, the total designer and the chief quantity manager approval send outs the diagram paper and the experiment production. If the blemish of the design is disheveled in the experiment produce, the design must be further perfect.
2. The safe assurance in manufacture stage
direct decision stage to aircraft dependable. It is the dependable to realize whole processes from the raw material into the factory to arrive to make into the finished product. The manufacturing process can guarantee the aviation the dependable.
First, the craft document of the high quantity need the establishment. The craft document must strictly carry out in the production. In order not to the person's factor influence, craft discipline must seriously carry out. Advance examine means need to be adopted. The quantity control system demand to establish. For guaranteeing to make the quantity of the process, we also want practice to identify to control the right production supplies.
The second, process supervises and controls to be practiced to quantity of special work. Their external appearance is very inside quantity of difficult detection problem in batch produce special, for example, the material craft process of the heat handle and weld. We must supervise and control these crafts the process, for insuring to guarantee the quantity safety.
The third, improving the quality, Producing with civility. It has the strict request to environment is in the aviation product production. It is a high request than general machine spare parts in the material and assembles etc. There are contain high request in the assemble production. Sometimes, any link or surplus thing would affect the aircraft safety.
From these, we can know the completely quantity management included two processes of the design and make. It is a chaperonage of the guaranteeing dependable in whole process aviation. It depend on the ground to guarantee the air, and the work guarantee the product, spare parts to guarantee whole machine, and attain the assurance aviation project.
