Abstract
An aircraft which includes elements providing air circulation and directing the circulation along a housing. Different operational stages of the aircraft such as take off and level flight are achieved by using the same functionally inter-connected elements. The circulation is achieved by fan elements that allow adjusting the blow direction and the blowing force of the flow. A stagnation point (SP) associated with the circulation is also formed if necessary below the housing and the aircraft can be steered by controlling the circulation and the position of the stagnation point (SP).
