Definitions

  • the present invention relates to an airplane with at least one lifting mechanism the outlet of which is adapted to be closed by two serially arranged flaps which are pivotable in the same direction about axes transverse to the direction of flight and near their front edges and which are also adapted to deflect the jet.
  • Airplanes have become known in which a plurality of lifting mechanisms have been combined to a unit in which a common outlet opening at the bottom side of the plane is adapted to be closed by flaps pivotable in the same direction.
  • one flap each is associated with the range of a lifting mechanism while the flap in one intermediate position simultaneously serves for deviating the jet of the driving mechanism for cruising.
  • Flap arrangements have been known according to which the flaps are arranged farther to the rear in the driving jet, so that the jet first leaves the outlet and only after passing a free path impacts upon the flaps. In partially opened condition, only a portion of the driving jet impacts upon the flaps. Furthermore, with completely opened flaps long flap portions protrude from the hull so that only a small ground clearance remains below the flaps.
  • FIGURE 1 shows the flap arrangement according to the invention in closed position
  • FIGURE 2 illustrates the flap arrangement of FIG- URE 1 in a position for the jet deviation
  • FIGURE 3 shows the flap arrangement according to the invention in completely opened position.
  • the front flap which is pivotable in flight direction is pivotable in a manner known per se about a fixed axis, whereas the pivot shaft for the rear flap is guided in a coulisse or sliding block firmly connected to the plane and extending approximately from the center of the opening toward the rear.
  • the side rear flap will from the start of the opening operation cause its top side to deviate the jet adjacent thereto toward the rear until it reaches an ineffective position.
  • two serially arranged guiding members may be provided for guiding the rear flap in said coulisse.
  • the front and rear flaps are each provided with an arm the ends of which are pivotally interconnected by means of a connecting rod which is preferably adjustable as to length.
  • a fixed point of the airplane may furthermore have linked thereto one end of a rod the other end of which is provided with an oblong hole surrounding holding means for the rear flap.
  • Flap 1 which, when looking in flight direction is located at the front, has its front end provided with a nose 1a.
  • the said flap 1 is by means of said nose 1a fixedly arranged on a shaft 2 which is rotatably journalled in hull 3 so that by turning the said shaft 2, flap 1 will be rotated.
  • shaft 2 has connected thereto one end of a rod or link 4 the free end 7 of which has linked thereto an additional rod or link 5 which, for purposes of a precise adjustment of the closing position (FIG.
  • flaps 1 and 6 are equipped with an adjustable length compensating member 8.
  • This member 8 is linked to a follower nose 14 of flap 6 and is adapted to pivot flap 6 along a coulisse 10 or slot stationary with regard to the hull.
  • Flap 6 slides in coulisse 10 by two guiding members 9, 9' arranged at that portion of flap 6 which is the front portion when looking in flight direction.
  • the intermediate portion of flap 6 has formed thereon a guiding pivot 13 which is adapted to slide in an oblong hole 11 of a guiding rod 12 which is pivotable about the shaft 15 stationarily arranged in the airplane.
  • one important advantage of the present invention consists in that both flaps, from the start of opening the same way cause jet deviation in rearward direction, and the opening movement of the rear flap can be designed favorably in view of the pivot shaft for said flap being guided in the coulisse or slot 10'.
  • An air plane having at least one lift drive mechanism with an outlet which includes: first and second flap means arranged in flight direction of said airplane one behind the other and when looking in said flight direction forming front and rear flap means respectively, said front and rear flap means respectively being arranged in the vicinity of the front and rear portions of said outlet for selectively opening and closing the same and deviating the jet from said outlet, shaft means supported by said plane and pivotally supporting said front flap means for pivoting about a stationary axis extending transversely to the longitudinal extension of said airplane, said airplane being provided with guiding passage means arranged in the vicinity of said rear flap means and in the vicinity of the rear portion of said outlet, guiding means connected to the front portion of said rear flap means and movably guided in said guiding passage means for pivoting movement of said rear flap means, said guiding passage means being so designed as to pivot said rear flap means about a movable axis extending transversely to the longitudinal direction of said airplane in a direction away from said stationary axis when said rear flap means is being pivoted in opening direction and in opening direction
  • said guiding passage means is formed by slot means, and in which said guiding means includes two guiding members spaced from each other and movable in said slot means.
  • said link means include a connecting rod adapted to be varied as to its length.
  • An airplane according to claim 1 which includes: lever means pivotally connected to said airplane and provided with slot means, and in which said rear flap means is provided with pin means slidably engaging said lastmentioned slot means.
