1. A thrust control system of an aircraft comprising:
an integral body comprising a central portion and a plurality of branches having longitudinal axes that substantially intersect said central portion;
an open-type central power unit configured to only control a lift of the aircraft, and open-type peripheral power units configured to control direction of movement of the aircraft, wherein
the central power unit comprises an upper and a lower propeller arranged one above the other and adapted to rotate in opposite directions, and
each of the peripheral power units comprising upper and lower propellers and the peripheral power units are located outside an aerodynamic operating range of the upper and lower propellers of the central power unit,
wherein the upper propeller of the central power unit is provided in substantially the same plane as the upper propellers of the peripheral power units, and the lower propeller of the central power unit is provided in substantially the same plane as the lower propellers of the peripheral power units.
