Conference paper


The development of extremely large, high gross weight aircraft over the past several years has greatly increased the significance of aircraft wake turbulence. The increased magnitude of this turbulence and its effect on other aircraft is of major concern to the aircraft community. This concern is evidenced by the very fact that this symposium is being held for the purpose of considering the wake turbulence phenomenon and developing methods to cope with its effects. From a practical, operational point of view, perhaps the two most critical areas of concern are the induced structural loads and vehicle upset which can result from wake vortex encounter.
