AI Technical Summary
Existing methods for obtaining aerodynamic parameters suffer from insufficient accuracy, high cost, long cycle time, and insufficient theoretical support in the field of small aircraft, especially in innovative designs and modified aircraft where there is a lack of suitable computational models and data foundation.
By using measurement parameters based on ground testing and flight, and by calculating the elevator, aileron, and thrust control coefficients, combined with a standard atmospheric model, the aerodynamic parameters of small aircraft, including total lift and drag coefficients, are calculated, providing a simple and easy-to-understand calculation model.
It improves the accuracy and calculation efficiency of aerodynamic parameters, reduces system costs, adapts to different aerodynamic layouts, supports engineering design optimization, and enhances aircraft performance.
