Definitions
- the invention relates to a model helicopter with a fuselage in which an engine and / or a remote control and / or a transmission is installed, and is generally airworthy is.
- Model helicopters that are airworthy and with a Remote control are known and known in use.
- Your rotor to generate lift is usually powered by an internal combustion engine, and the steering is done with the help of remote-controlled servo motors, which among other things the Inclination angle of the rotor blades and the throttle valve of the engine, and so the movement around the different spatial axes or the flight direction of the helicopter.
- At the stern is a another rotor attached, its rotation around the vertical axis prevented and with a tail rotor shaft, which has a gearbox with the engine connected, is driven.
- the Hull made of shell-like plastic parts, the form a hollow body, composed, in particular finds glass fiber reinforced plastic here Application. The parts are z. B. deep drawn or injection molded and with suitable adhesives connected.
- the drive motor, the remote control and that Gearbox or drive mechanism installed In in most cases they are the ones that actually exist Replicas of helicopters.
- Model aircraft are also known from model making, whose hull is formed by a single component is, usually a suitably shaped, massive styrofoam body. It is with cutouts for the inclusion of z. B. the engine, the remote control or the batteries. During installation only the built-in parts in the corresponding Cutouts used and possibly secured against falling out of the fuselage.
- the Wings which also consist of only one molded polystyrene component can be made in the usual Way with rubber rings attached to dowels protrude from the fuselage, are attached to the model airplane attached.
- the advantage of such Design is that the individual components are installed in the fuselage, and the balance of the flight model due to incorrect installation cannot be affected.
- a disadvantage of previously known model helicopters is that the built-in parts, such as remote control or motor, practically not against vibrations are protected. In the event of accidents the complicated controls and the unstable flight behavior never avoided by model helicopters the built-in parts can be removed from their anchorages torn and thereby damaged or others Damage components, so that expensive repair work become necessary. Furthermore is a fixed installation, for example of the engine, in a hull made of shell-like plastic parts is composed with considerable constructive Effort connected and requires a certain amount Level of craftsmanship.
- the problem underlying the invention is a model helicopter so that the tax and flying the model helicopter Installation parts can be assembled quickly and easily and against damage in an accident of the model helicopter are protected, and in simpler Way can be assembled.
- the problem is solved by that the hull is composed of two massive half-forms is, and the half forms with recesses for engine and / or transmission and / or remote control are provided.
- the main idea of the invention is that the fuselage of the helicopter made of two solid half forms is assembled, and the built-in parts, such as B. the remote control or the motor, in corresponding Recesses used in the half molds become.
- the massive design means the half-shapes that the entire fuselage of the helicopter, apart from the recesses, from the Material of the half-forms is filled in, analogously to the model airplane described above from one Component.
- the material from which they are made is irrelevant according to the invention, but it must have a relatively low specific weight, otherwise the helicopter will no longer be able to fly is.
- the half forms are provided with recesses, in which, among other things, the engine, the remote control with their servo motors or the drive mechanics used when assembling the model and if necessary be fixed in it.
- the shape and Size of the half-shapes is within the scope of the invention freely selectable, however, they will be like it below explained, carried out essentially symmetrically become.
- the way the two are fastened Half forms to each other can be known in the art Way, tailored to the respective material, be performed, e.g. B. by gluing or screwing.
- the advantage of the invention is that the Installation parts into which recesses are inserted and against shocks or damage are protected from an accident and that the trim of the model helicopter due to improper use Installation can be affected. Moreover is creating a hull from just two massive ones Half forms much easier and faster feasible than with previously known model helicopters. The invention also enables it to be crafted less gifted people deal with this Hobby to deal with.
- Styrofoam is suggested as the material for the half molds. It is already for the production of Fuselages are known for model aircraft, and can be used for Helicopters are processed in an analogous manner. The production of the half molds, as well as the application the recesses for the built-in parts is the specialist possible. The advantage of styrofoam is a little in that it is easy to work with has specific gravity and over a large Impact resistance to protect the built-in parts. It can also be designed so that it is resistant to fuels and lubricants.
- the half forms are with dowels, protruding out of the fuselage, for example wooden dowels that are in suitable Cutouts inserted in the half molds and glued become. Be in the assembled state then rubber rings, as is common in model airplane construction are so attached to the dowels that that of the resilient force exerted on the stretched rings presses the two half forms together.
- dowels protruding out of the fuselage
- suitable Cutouts inserted in the half molds and glued become.
- rubber rings as is common in model airplane construction are so attached to the dowels that that of the resilient force exerted on the stretched rings presses the two half forms together.
- the fuselage has a pipe for receiving it the tail rotor shaft, in which the rotating drive shaft of the tail rotor is guided, so that they are not in direct contact with the material of the half-forms and can damage it.
- Equipment of the fuselage with such a device as well as the selection of a suitable material is possible for the specialist.
- the half molds with stiffeners to provide, the nature of the invention is irrelevant. They are said to be the stability of the Increase fuselage or twist the helicopter reduce around the longitudinal axis.
- the semi-molds with stiffening ribs to provide, d. that is, ribs on the half forms or webs are formed. You can in that A person known in the art during production formed as part of the massive semi-form, or subsequently, e.g. B. also from other materials existing, be attached.
- fiber reinforced Plastic proposed as a further material for the half molds. He is, especially as a glass fiber reinforced plastic in Model building known. Its processing into one Half shape, which is provided with recesses possible for the specialist. It is very impact-resistant, tough and can be designed to be resistant against the fuels and lubricants, so that he the the material requirements for the Half forms are sufficient.
- the glass fiber reinforcement exists Made of fabric mats or fleeces that are in the liquid State inserted in the plastic and for Serve to absorb tensile and shear forces.
- Figure 2 are the two symmetrical half forms (1,1a), the right and left half of the fuselage Form model helicopter, shown. you will be along the vertical plane through the The longitudinal axis of the fuselage is composed. To simplify the illustration, devices that fasten the half molds together, like e.g. B. dowels and rubber rings, not shown.
