Research On Helicopter Flying-quality Evaluation Software Technology

Helicopter flying quality evaluation is comprehensive evaluation of manipulability and comforting of the specify helicopter. The evaluation, including quantitative and qualitative evaluation, is done by helicopter driver and related engineering technology people according to the decided flying quality criterion. This paper aim to develop helicopter flying quality evaluation package realizing on-line and off-line helicopter fly quality quantitative evaluation. The paper is based on Linux operating system and C++ development language, Qt/Qt Designer development environment and ADS-33E flying quality criterion and flying quality of domestic some helicopters flying quality criterion.The package consists of three modules of large data processing, real time on-line engineering simulator data collection and off-line engineering analysis processing. Fly examination data play at various speed and can be real-time playing, pausing, stopping, dragging left - rightward and up-downward, local zoom and exiting. The paper make measures of altering color and speed of playing data and giving an alarm while curve's variance changing for the sake of improving large fly examination data processing efficiency and reducing manipulation intensity. It realized getting subsection data pigeonholing automatically and showing by loading. It can also get variety evaluation parameters by mouse getting data and make marker on related picture or show evaluation result on tabulation automatically.By the research on helicopter flying quality evaluation software technology, the paper realize user password, creating project file or loading it, selecting evaluation subject and reading subject definition, selecting the source of evaluation data, selecting valid data, data assistant processing and marking helicopter fly quality criterion picture, which can be saved by standard graphics format and pigeonhole automatically and be embedded into MS Word and Open Office directly.
