Definitions

  • the present invention relates to a toy plane able to fly by remote control in an enclosed space or protected from the wind, especially in a room.
  • the room in which the plane can fly can be a room relatively small dimensions like a room an apartment or a house (living room, bedroom, bathroom etc.).
  • Airplane toys are very popular with children especially when you can make them steal.
  • the most elaborate are scale models reproducing the essential characteristics of a real airplane and which are remotely controlled by track over the air. They have a heat engine or electric to turn the propeller, a tank fuel or battery and control mechanism rudders and elevators. Engine and the control mechanism for the control surfaces are controlled thanks to a transmitter housed in a control box and a receiver installed on the aircraft. These models discounts are for teenagers or adults and in most cases you can hardly qualify as toys.
  • radio controlled airplanes are relatively heavy and therefore fly at a relatively high speed. Those are must have outdoor planes. Any structural modification would only allow them transform into an interior cheek for a reduced space Nice than an apartment. The need to find open land considerably limits use of these planes.
  • the present invention has been designed to provide a solution to this problem. It made it possible to design a flying machine easily usable.
  • the remote-controlled and flying airplane according to the invention is intended for a child, which is the most likely case for this type of object, it is imperative that it is not dangerous, not only when he flies but also when the child manipulates it. This toy will also have to be robust to be able to resist impact and manipulation while remaining extremely light.
  • the maximum speed at which the model plane must fly has been rated at 2 m / s.
  • a child can easily control the flight of the airplane model.
  • the connecting cable is not not intended to be stretched.
  • the flight domain is therefore not not limited to the surface of a sphere as in the case of circular flight.
  • the airplane model can evolve freely in all directions.
  • the plane model To fly at such a low speed, the plane model must be very light. It is estimated that the wing loading of the aircraft model trailing the connecting cable should be ⁇ 1.5 g / dm 2 . We were able to obtain this low wing loading value because, the toy aircraft according to the invention being with connecting cable, there is no power source or radio control receiver carried on board the model. plane.
  • Figure 1 shows the three elements essentials of the toy aircraft according to the invention: the airplane model 1, the control device 2 and the cable 3 ensuring the electrical connection between the model aircraft and the control device.
  • the control device 2 comprises a battery 21 serving this source of electrical energy can be switched on by switch 22.
  • a battery 21 serving this source of electrical energy can be switched on by switch 22.
  • switch 22 To make the controller more attractive, we can give it the shape of a modern airplane steering wheel that is to say provide it with two handles 23 and 24 are attached to the central part 25 which comprises electrical and electronic control elements.
  • On the left handle 23 is the control member 26 of the engine 11 of the airplane model driving the propeller 19.
  • the control members 26 and 27 operate variable resistors or dimmers power electronics that can be found easily in trade. Terminal voltage of the motor must be adjustable from 0 to the maximum voltage. Voltage across the rudder actuator (which will be described later) must be adjustable between a negative maximum voltage value and a value positive of maximum voltage, this maximum voltage may be different from that supplying the engine.
  • the two control members 26 and 27 are provided springs that bring them back to a neutral position correspond to 0 V in both cases.
  • the electrical connection cable must be as light as possible and for that the electric wires that make it up should be as light as possible, therefore the finest possible. Intensity who runs through them must therefore be limited to a low value. It is therefore necessary, to have a sufficient power, to provide a voltage relatively large.
  • the tension maximum power of the electric motor 11 can be 9 V while the control voltage of the actuator can vary between + 9 V and - 9 V.
  • the electrical connection cable 3 must be flexible and very light so as not to hinder developments of the airplane model 1. A length of about 1.75 m seems well suited for operation in a medium-sized living room.
  • a cable electric of this length and not weighing, feel them connection sockets which 0.6 g knows about 0.35 g / m.
  • This cable is shown alone in Figure 2. It is composed of four conducting wires 31, 32, 33 and 34 0.1 mm in diameter, two wires being intended for power the electric motor and two wires being reserved for the rudder actuator. These wires are made of copper and are electrically insulated with a varnish. We can thus group them in the fold of a fold 35 made from a ribbon of plastic folded in half.
  • Plastic tape used can be 4 mm wide for 10 or 12 ⁇ m thick which is a common thickness for manufacturers of plastic films. It is advantageous to use a little tearable plastic because lengthening a lot before rupture, for example the polyethylene or polypropylene.
  • the cable is finished, device side control, by a connector with four contacts.
  • Another four-way connector connects the cable to the model plane.
  • This last connector can have a weight equal to or less than 0.1 g if chosen from certain minaturized connectors used in computer or mobile phone equipment.
  • These connectors are preferably sized to allow easy disconnection at the slightest abnormal effort. This protects the electric cable and the constraints aircraft model mechanical too important.
  • FIG. 3 represents an airplane model 1 in exploded view but with incomplete wings.
  • its wingspan can be 45 cm, its length by 40 cm, the surface area of the wings by 4.5 dm 2 and its weight by 6 g.
  • the electrical connection cable is attached to the airplane model by its connector, below the model and near its center of gravity.
  • the powertrain 100 is made up electric motor 11, a propeller and a cone propeller 106.
  • Motor 11 must have an excellent ratio power over weight. It can be a direct current with very powerful brushes and magnets (rare earth magnets). The consumption of this engine is around 200 mA at a voltage 7 V power supply.
  • the powertrain must be able to lift two-thirds when stationary the weight of the aircraft, in this case 4 g, i.e. slightly less than twice the weight of the group motor-propellant.
  • the motor can be of the type used in micro-mechanism and equipped with magnets at samarium-cobalt. Engines of this type are available for a weight of around 3.2 g. This weight be reduced by choosing wisely materials and dimensions of the constituent elements.
  • the propeller must not be dangerous. For that, it is flexible, which contributes to solidity. It has a hub 101, which plugs in and sticks on the axis 111 of the motor 11, and two blades 102.
  • a blade is made from film flexible plastic, about 50 ⁇ m thick, folded in half and is slightly arched.
  • Each blade root 103 of the hub is plugged into the fold of each fold 102 constituting a blade.
  • the sides facing each other of each fold are glued incorporating the foot of corresponding blade.
  • the propeller cone 106 protects the propeller and the engine. It is preferably made of plastic expanded to absorb shocks.
  • FIG 4 is a detailed view of the model plane showing rudder 12 and its actuator 200.
  • This actuator must be very light because the aircraft model yaw inertia must be very low in order to have maneuverability when cornering sufficient. Its weight is preferably around 0.3 g. It is advantageously of the type used for mobile equipment of needle multimeters.
  • he includes a permanent magnet 201, Sm-Co or Fe-Nd, linked to an axis 202 (for example in piano string) integral with the rudder 12 and constituting the axis of rotation of this rudder.
  • axis 202 for example in piano string
  • the induction coil 203 is fixed to the fuselage 14 (see Figure 3) by a piece of tape adhesive.
  • a plastic strand 16 in two parts, is fixed on the one hand to the fuselage 14 by gluing and on the other shares the rudder 12. It constitutes a spring element which tends to hold the rudder in neutral position.
  • Figure 4 also allows you to realize of the rudder constitution, the rudder being also constituted on the same principle.
  • a flexible plastic strand 204 with a diameter of 0.6 mm is closed on itself and heat-sealed so as to constitute the periphery of the rudder.
  • Plastic strand 16 is glued to strand 204 on level and behind the actuator 200 which it surrounds.
  • Plastic film 205 8 ⁇ m thick is stretched over the strand 204 and the edge of the film is folded around the strand 204 to be glued or heat sealed on itself.
  • this part consists of an envelope made of plastic film 10 ⁇ m thick and shaped like the fuselage 14 and leading edges 15.
  • the connection between the fuselage and leading edges (by gluing or heat sealing) must be rigid enough to avoid the wings do not collapse.
  • a connecting flange at this level may possibly be necessary to increase the stiffness of the connection.
  • Leading edges 15 are preferably slightly conical in shape, their diameter decreases as one moves away from the fuselage.
  • Each leading edge and attached to the fuselage so as to give the corresponding wing a dihedral a few degrees and an incidence of 5 °.
  • the envelope can also include 10 legs instead of usual wheels to support the aircraft model when he's on the ground. Alternatively, these legs can be of a different structure and related to the model plane.
  • the envelope is inflated to a pressure about 5 mbar higher than atmospheric pressure.
  • the envelope can be sealed or a re-inflation valve.
  • the electric motor 11 is glued to the front face of the fuselage 14 with, optionally, interposition of a reinforcement pad.
  • each wing consists of a flexible strand of plastic 17 of about 1 mm in diameter play the role of trailing edge, and of a plastic film 18 of 8 ⁇ m thick.
  • Strand 17 is attached by one from its ends to the distal end of the edge attack 15 and by its other end to the fuselage 14.
  • the film 18 is stretched between the leading edge 15, the trailing edge 17 and the fuselage. It is fixed by bonding or heat sealing at the leading edge and at fuselage. It is fixed by gluing or heat sealing on itself after covering the strand 17.
  • Figure 6 shows, so structural, another model of aircraft.
  • the fuselage and the leading edges of the wings consist of plastic tubes with very thin walls thin.
  • a good example of usable tubes is made up of straws used for drinking. These straws have a diameter ranging from 5 to 7 mm and have a 150 ⁇ m thick wall.
  • the landing gear can advantageously also be made up of such tubes.
  • a central tube 50 constitutes the main axis of the structure. On its end advent will be fitted and stuck on the powertrain. On its end rear will be fixed the rudders and direction.
  • the front part of the tube 50 supports also the landing gear consisting of two sections of tube 51 and 52.
