ABSTRACT
There are two main purposes for our research on wake vortex: one is to improve operation safety, the other is to reduce the wake spacing and ensure the runway capacity and operation efficiency under the premise of ensuring safety. By comparing and analyzing the technology of wake spacing reduction, we have studied aerial classification technology, synchronous offset approach technology, high glide slope approach technology, wake vortex warning system, aircraft wake vortex interval system and so on. Research shows that by proposing advanced concepts or improving the ATM program, namely the wake interval reduction technology, we can avoid the influence of the wake generated by the front aircraft, ensure the operation safety and increase the airport capacity by 3.7%-25%. The key technology of the wake interval reduction technology is the wake vortex prediction model and the safety analysis of the wake encounter. However, the higher the accuracy of the model is, the more complex the computation is. The research on wake detection technology will be the future development direction.

Experimental Studies on the Interaction of Jets with the Vortex Wake of Slender Bodies
An experimental study has been conducted to examine the low-speed aerodynamic characteristics of a pair of circular jets behaviour in the vortex-wake of a blunted cone cylinder-body combination with and without a 70° leading edge sweep delta wing. The ...
