    Abstract
  • Aircraft load spectrum measured data visual simulation is an important means to identify maneuver and to verify the validity of measured data in flight testing. A data storage method based on logical data channels was put forward to solve the structural differentiation problem of different data sources caused by different measured objects; for the performance problems caused by model complexity when large amount of measured data was used to simulate the whole flight course, physical channel and logical data channel analytical model were established; based on data double-buffering and drawing double-buffering mechanisms, flight model and visual simulation system environment of measured data were established, and the measured flight data of different testing aircrafts were analyzed and verified. The results show that the visual system meets the verification of flight measured data and the demand of maneuver recognition of GB level load spectrum of different types well, and can reproduce the entire course of the flight completely. It provides a visual platform to identify maneuver of flight course of aircraft, verify the data validity and post process of data.
