Arrangement of adjustable hub jet engines that can be extended from the plug-in fuselage on V / STOL aircraft

The invention relates to the arrangement of lift jet engines at ¥ / STOL flag eyes, with the hub jet engines are arranged so that they can be operated from the. Fuselage extended, steepened in different beam directions during operation and completely in the Aircraft fuselage can be retracted »

For use in the V / STQL phase of jet-driven V / STOL aircraft are built into the aircraft fuselage Lifting engines with vertical jet direction known »This one Arrangement has the disadvantage that the effective lever arms of the vertical lifting forces with respect to the aircraft longitudinal axes are small, and the V / STOL phase is therefore unstable. In order to enlarge the lever arms, the lifting mechanisms for vertical jet direction also firmly in the wing to be installed in front of aliens by large aircraft »Nachte'il'i'g is _ that by this solution the strength of the wing construction is reduced, which causes ausätalichen construction effort »In

As is known, the march engines are also arranged on the wing ends of jet-powered V / STOL aircraft so that they can be adjusted in the vertical direction of the beam * · Ο this results in a disadvantageously high load on the wing. ¹ It has also been arranged in special gondolas, which fold close to the aircraft fuselage when cruising. Nevertheless, such gondolas bring about a disadvantageous increase in the largest cross-section of the fuselage of the aircraft have jet nozzles arranged on the side of the fuselage, which are designed in such a way that the exiting thrust jet can be deflected in a vertical direction>^;'TO' act as a lifting jet Attack the longitudinal axis of the aircraft, which makes the V / STOL phase unstable again »In addition, the deflection of the thrust jet results in considerable thrust losses." Jet nozzles arranged on the side of the aircraft fuselage also have the disadvantage that they again enlarge the largest fuselage cross-section and the flow conditions worsen O

The invention is based on the problem of the lack of known arrangement of Hubtri ebverken and avoid to find a new arrangement which the during the
