Definitions

  • the present invention relates to a remote-controlled model plane comprising a fuselage and wings, a tailplane and/or tail fins attached thereto.
  • Conventional prior art model planes are constructed of a rigid fuse ⁇ lage to which wings with or without ailerons are attached and of a tail having a tailplane and tail fins with rudders for steering.
  • Such a model plane is steered by causing a sufficient change of angle in the rudders, which is produced by means of push rods attached to the rudders and by servos steering them.
  • this currently employed prior art is attended by consider ⁇ able drawbacks. Hence, making a model plane construction to be light enough constitutes a common problem.
  • the tail of the model plane tends to be too heavy on account of the push rods driven into it and the requisite rudders and their joint constructions.
  • a model plane that is too heavy at the tail must be stabilized for example by constructing a long nose section, which will make the model plane stall more easily and more deeply.
  • a heavy, long-nosed model plane is difficult to handle, especially for a beginner.
  • the model plane of the present invention is primarily characterized in that the fuselage is bipartite substantially in the di ⁇ rection of its longitudinal axis, so that it comprises a front fuselage and a rear fuselage which are interconnected, the junction of the front and rear fuselage being located in the region between the wings and tailplane, and the junction comprises means for enabling relative swivelling of the fuselage parts.
  • the invention is based on the idea that steering of a conventional model plane by rudders provided in the tail of the fuselage involves a change in the angle of the rudder relative to the longitudinal axis of the fuselage.
  • this change of angle is accomplished in such a way that the fuselage is divided into two parts, and thus the entire rear portion of the fu- selage can be moved similarly as a rudder upwardly, downwardly or laterally, thus producing the requisite change of angle of the rudders relative to the imaginary longitudinal axis of the fuselage.
  • the invention affords significant advantages.
  • the model plane is considerably simpler to construct than a conventional model plane, since there is no need to construct mobile rudders with push rods, levers, joints and hinges at the rear of the fuselage.
  • the tailplane, tail fins and tail boom of the model plane can be dimensioned to be lighter.
  • the model plane of the invention is, particularly for a beginner, much easier to fly than a conventional model plane; its stalling properties are better and its aerofoil load smaller. Since the model plane is easier to handle, it is not prone to fatal accidents resulting from a steering error, which will lengthen the service life of the model plane.
  • the steering solution in accordance with the invention also makes it possible to fly the model plane in a small space, as the required turning radius is distinctly smaller than in a conventional model plane.
  • Figure 1 illustrates a conventional prior art model plane
  • Figure 2 is a schematic side representation of the steering move- ments of the fuselage
  • Figure 3 is a schematic top representation of the steering move ⁇ ments of the fuselage
  • Figure 4 shows a vertical cross-section of the junction of the fuse ⁇ lage when two hinges are used as a joint
  • Figure 5 shows a horizontal cross-section of the junction of the fu ⁇ selage when two hinges are used as a joint
  • Figure 6 represents a side view of the junction of the fuselage when a cross joint is used
  • Figure 7 shows a horizontal cross-section of the junction of the fu- selage when a cross joint is used.
  • a model plane 1 comprising a fuselage 2 and attached thereto wings 3 with their ailerons 4 and a tailplane 5 with a rudder 6 and a tail fin 7 with a rudder 8.
  • Such a conventional model plane is steered by directing a moving command to the ailerons and rudders, said command being directed by radio control.
  • the fuselage 2 of such a conventional model plane is rigid for its entire length, and ailerons 4 and rudders 6 and 8 articulatedly (e.g. hingedly) joined to the wings 3 and the tailplane 5 and tail fin 7 are used to steer the model plane.
  • Figures 2 and 3 are schematic representations of a preferred em ⁇ bodiment of a model plane 10 in accordance with the present invention.
  • the fuselage of the model plane is divided into two parts substantially in the direc ⁇ tion of its longitudinal axis and thus forms a front fuselage 11 and a rear fuse ⁇ lage 12, which are articulated to one another.
  • the rear fuselage can be turned relative to the vertical axis of the model plane 10 and also relative to the horizontal axis of the model plane, as shown by broken lines in the figures.
  • the model plane 10 of the invention is steered by known means similar to those employed in a conventional model plane 1 , whereby moving commands are directed by steering servos (not shown) to ailerons 13 and the rear fuse- lage, said commands being transmitted to these parts by push rods (not shown) provided in the model plane.
  • the movement of the steering servos is controlled in the normal way by radio control.
  • the junction 14 of the front fuselage 11 and rear fuselage 12 is lo ⁇ cated between the wings 15 and tailplane 16 in the model plane 10, preferably in the vicinity of the wings. Since the model plane is thus steered by turning the rear fuselage 12, the tailplane 16 and tail fins 17 in the model plane may be substantially rigid, and they are not provided with any turning rudders. As the tail of the model plane is lighter than that of a conventional model plane, also the nose of the model plane can be shortened while maintaining a correct centre of gravity. The model plane is also considerably swifter in movement than a conventional model plane, since as the steering takes place by moving the parts of the fuselage relative to one another a more efficient turning movement is produced than with the mere turning of a rudder.
  • a tailplane steering rod 18 and a tail fin steering rod 19 are preferably provided in the rear fuselage 12 of the model plane in ac ⁇ cordance with the invention for steering the movements thereof.
  • the tailplane steering rod 18 is disposed in the rear fuselage 12 at fixing point 20, preferably in a ball joint, the preferred location of which is on the lon ⁇ gitudinal axis 22 of means 21 permitting movement about an axis parallel to the vertical axis of the model plane.
  • the tail fin steering rod 19 is also dis ⁇ posed in the rear fuselage 12 at fixing point 23, preferably in a ball joint, the preferred location of which is on the longitudinal axis 24 of means 21 permit ⁇ ting movement about an axis parallel to the horizontal axis of the model plane. In that case, the steering movements directed to the rear fuselage do not in ⁇ fluence each other.
  • the articulated joining of the rear fuselage and front fuselage in ac ⁇ cordance with the invention can be implemented by a cross joint 21 known per se in accordance with Figures 4 and 5, and thus the fixing points of the push rods are located in the same cross-sectional plane on the extension of the axes of the horizontal joint and vertical joint of the cross joint.
  • the articulated joining of the rear fuselage and front fuselage in ac ⁇ cordance with the invention can also be implemented for example with two hinges 25 and 26 known per se, in accordance with Figures 6 and 7.
  • the hinge 25 permitting tailplane steering, i.e. movement about an axis parallel to the horizontal axis of the model plane
  • the hinge 26 permitting tail fin steering, i.e. movement about an axis parallel to the vertical axis of the model plane, substantially immediately adjacent one another.

Abstract

Modèle d'avion réduit télécommandé comprenant un fuselage auquel sont fixés des ailes (15), un stabilisateur (16) et/ou des plans fixes de queue (17). Les modèles d'avion classiques comportent généralement un fuselage rigide; de ce fait, la queue a tendance à être trop lourde en raison des poussoirs (18, 19) qui y sont introduits, ainsi que des gouvernails requis et de leurs structures d'articulations. Ce genre de modèle lourd est difficile à manier, en particulier pour un débutant. En prévoyant un fuselage en deux parties, on obtient une structure plus légère et plus facile à manier, dans laquelle toute la queue du fuselage peut être déplacée à la manière de gouvernails pour produire les mouvements d'orientation.
