Research On Data Mining Of Flight Data Simulation Based On Flight Gear

To develop the aviation industry,we need not only to research,design and manufacture aircraft,but also need many high-quality flight reserve personnel.In terms of economy and efficiency,flight simulation training has certain practical significance for young people's science education and the training of flight reserve personnel.The existing flight simulation software as started slow,no control tips,does not have the intelligence interaction function,often let beginners loss,is not conducive to flight enthusiasts to the pilot of the learning technology,thus wasting a lot of valuable learning time of flight enthusiasts.A series of problems in the flight simulation software,the fundamental reason is because the flight simulation software in the design is just a data input,processing,output system,through the analysis of the data does not have the knowledge transfer knowledge and intelligent interaction to the user's ability to make the flight training personnel and lack of initiative to obtain knowledge from the system of flight attractive.In order to improve the level of intelligent flight simulation software,this paper built a Flight Gear aircraft flight simulation training system based on relevant data,and simulation algorithm for flight training to stall flight enthusiasts for mining through Apriori data mining,association rules mining design and the final results are applied to the flight simulation system of flight training tips.Provide air driving control theory based on information visualization in simulation exercises for each simulation,help students overcome the fear of stall early training.By simulating the auxiliary training of the flight training system,the flight simulator can quickly correct the error,be familiar with the landing process,improve the learning efficiency and shorten the learning cycle.This paper through the collection,storage and mining work simulated flight data of Flight Gear,construction of flight training simulation based on data mining system,and the use of data mining technology on simulated flight training tips system design optimized.The main work in the following aspects:first,through the comparison of important parameters related to function of flight technology,the use of platform design,select 12 flight attribute parameters to construct the simulated flight training notification system;two is based on the characteristics of Flight Gear data,using the method of reading XML files,extraction,storage of 12 flight attributes,for the three important process during the flight that take off,flight and landing,the design of the 15 simulated flight training text information;three is to stall in flight,5 flight attribute index,the use of data mining in sorting pretreatment,queue buffer method cleaning and pretreatment of the single index data and multi index data,and based on the analysis of a large number of simulation of stall flight test data,the pitch angle and roll angle The range of yaw angle is defined,and the application of aircraft stall prompt in flight training,flight and landing stage is realized.Simulated flight training prompting system based on Flight Gear,in the city of Chongqing Nankai Middle School carry out pilot Science Technology Youth Eagles program verified,the effect is significant,the youth flight enthusiasts affirmed,has certain practical significance on adolescent science education and talents training flight.
