AN ESTIMATION METHOD OF LIFT-DRAG RATIO IN FDAS

摘要

yanghang FDAS ratio estimation method in accordance with an embodiment of the present invention, the free flight of the aircraft 6 , using the equation of motion of each axis direction in the acceleration of the body (x, y, z) and the phase represented by the equation , by modifying the equation shown by the equations of motion to obtain the flight equation for lift and drag coefficients , the step represented by a mathematical formula and data recorded in the black box (QAR) , wherein the rest , except for yanghang ratio , type QAR data to the equation includes the step of calculating the ratio the ratio of the lift and drag coefficients yanghang . ; can give practical help to build various standard operational and economic system operated by estimating the yanghang non- flight analysis , according to the above structure .
