Abstract: In order to make the functionality and performance test of all parts of the new planes accurate, and give assistance to the designers to maximize the test of each moment, the flight simulation platform proposes demand which needs higher simulation accuracy. It includes completing the real-time solver of flight simulation model, simultaneously collecting and storing 5 000 simulation data in 1 ms simulation cycle. This work introduces ping-pang cache storage algorithm and two kinds of real-time data acquisition algorithm which are compact acquisition and choose acquisition. And in this work, the millisecond level simulation cycles, huge amounts of high-speed real-time data acquisition and storage is solved.

Key words: engineering aircraft simulator, data acquisition, data storage, choose acquisition, ping-pang cache, compact technology
