摘要：

The paper presents a mathematical model of the aircraft vortex wake for evaluating the safe separation considering the wake-generating and following aircraft types and weather conditions. The solution of four major problems is contained in the model concerned, namely, the wake generator, the interaction of the following aircraft with the preceding aircraft vortex, the description of the turbulent atmosphere, and the vortex destruction. Verification of the model was made based on experimental results of wind-tunnel and flight tests. Given are calculations of the wake characteristics aft of particular aircraft and safe distance values in landing with various turbulent atmosphere states.
