Abstract
Description
Die Erfindung bezieht sich auf einen Modellhubschrauber mit einem Rumpf, in dem ein Motor und/oder eine Fernsteuerung und/oder ein Getriebe eingebaut ist, und der im allgemeinen flugfähig ist.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.
Modellhubschrauber, die flugfähig sind und mit einer Fernsteuerung gelenkt werden, sind bekannt und gebräuchlich. Ihr Rotor zur Erzeugung des Auftriebs wird üblicherweise von einem Verbrennungsmotor angetrieben, und die Lenkung erfolgt mit Hilfe von ferngesteuerten Servomotoren, die unter anderem den Neigungswinkel der Rotorblätter und die Drosselklappe des Motors beeinflussen, und so die Bewegung um die verschiedenen Raumachsen bzw. die Flugrichtung des Hubschraubers steuern. Am Heck ist ein weiterer Rotor angebracht, der seine Rotation um die vertikale Achse verhindert und mit einer Heckrotorwelle, die über ein Getriebe mit dem Motor verbunden ist, angetrieben wird. In einer üblichen Ausgestaltung des Modellhubschraubers wird der Rumpf aus schalenartigen Kunststoffteilen, die einen Hohlkörper bilden, zusammengesetzt, insbesondere findet hier glasfaserverstärkter Kunststoff Anwendung. Die Teile werden z. B. tiefgezogen oder spritzgegossen und mit geeigneten Klebstoffen miteinander verbunden. In den Rumpf werden unter anderem der Antriebsmotor, die Fernsteuerung und das Getriebe bzw. die Antriebsmechanik eingebaut. In den meisten Fällen sind sie den tatsächlich existierenden Hubschraubern nachgebildet. 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. In a usual one Design of the model helicopter is 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. In the fuselage, among other things 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.
Aus dem Modellbau sind auch Modellflugzeuge bekannt, deren Rumpf von einem einzigen Bauteil gebildet wird, meist einem entsprechend geformten, massiven Styroporkörper. Er ist mit Aussparungen für die Aufnahme von z. B. dem Motor, der Fernsteuerung oder der Batterien versehen. Bei der Montage werden lediglich die Einbauteile in die entsprechenden Aussparungen eingesetzt und eventuell gegen ein Herausfallen aus dem Rumpf gesichert. Die Flügel, die ebenfalls aus nur einem geformten Styroporbauteil angefertigt sein können, werden in üblicher Weise mit Gummiringen, die an Dübeln, die aus dem Rumpf herausragen, eingehängt sind, am Modellflugzeug befestigt. Der Vorteil einer solchen Bauweise besteht darin, daß die einzelnen Komponenten ortsfest im Rumpf eingebaut sind, und die Balance des Flugmodells durch einen falschen Einbau nicht beeinträchtigt werden kann.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.
Ein Nachteil bisher bekannter Modellhubschrauber besteht darin, daß die Einbauteile, wie Fernsteuerung oder Motor, praktisch nicht gegen Erschütterungen geschützt sind. Bei Unfällen, die aufgrund der komplizierten Steuerung und des labilen Flugverhaltens von Modellhubschraubern nie zu vermeiden sind, können die Einbauteile aus ihren Verankerungen gerissen und dabei beschädigt werden oder andere Komponenten beschädigen, so daß aufwendige Reparaturarbeiten notwendig werden. Desweiteren ist eine ortsfeste Montage, beispielsweise des Motors, in einem Rumpf, der aus schalenartigen Kunststoffteilen zusammengesetzt ist, mit erheblichem konstruktivem Aufwand verbunden und erfordert ein gewisses Maß an handwerklichem Geschick.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.
Der Erfindung liegt das Problem zugrunde, einen Modellhubschrauber so zu gestalten, daß die zum Steuern und Fliegen des Modellhubschraubers notwendigen Einbauteile in einfacher und schneller Weise montierbar und gegen Beschädigungen bei einem Unfall des Modellhubschraubers geschützt sind, und in einfacher Weise zusammengebaut werden kann.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.
Erfindungsgemäß wird das Problem dadurch gelöst, daß der Rumpf aus zwei massiven Halbformen zusammengesetzt ist, und die Halbformen mit Aussparungen für Motor und/oder Getriebe und/oder Fernsteuerung versehen sind.According to the invention, 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.
Der Kerngedanke der Erfindung besteht darin, daß der Rumpf des Hubschraubers aus zwei massiven Halbformen zusammengesetzt ist, und die Einbauteile, wie z. B. die Fernsteuerung oder der Motor, in entsprechende Aussparungen in den Halbformen eingesetzt werden. Dabei bedeutet die massive Ausgestaltung der Halbformen, daß der gesamte Rumpf des Hubschraubers, von den Aussparungen abgesehen, von dem Material der Halbformen ausgefüllt ist, analog zu dem oben beschriebenen Modellflugzeug aus einem Bauteil. Das Material, aus dem sie angefertigt werden, ist erfindungsgemäß unerheblich, es muß jedoch ein relativ geringes spezifisches Gewicht aufweisen, da ansonsten der Hubschrauber nicht mehr flugfähig ist. Desweiteren muß es resistent sein gegen die chemisch aggressiven Treib- und Schmierstoffe des Verbrennungsmotors, und es muß schlagfest sein, um sowohl die Einbauteile bei einem Unfall zu schützen und dabei selbst nicht beschädigt zu werden. Die Halbformen sind mit Aussparungen versehen, in die unter anderem der Motor, die Fernsteuerung mit ihren Servomotoren oder die Antriebsmechanik bei der Montage des Modells eingesetzt und gegebenenfalls darin befestigt werden. Die Formgebung und Größe der Halbformen ist im Rahmen der Erfindung frei wählbar, sie werden jedoch, wie es weiter unten erläutert, im wesentlichen symmetrisch ausgeführt werden. Auch die Art der Befestigung der beiden Halbformen aneinander kann in dem Fachmann bekannter Weise, auf das jeweilige Material abgestimmt, durchgeführt werden, z. B. durch Verkleben oder Verschrauben.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. Furthermore, it must be resistant to the chemically aggressive fuels and lubricants of the internal combustion engine and it has to be impact resistant to both the built-in parts in the event of an accident protect and not get damaged yourself. 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.
Der Vorteil der Erfindung besteht darin, daß die Einbauteile in die Aussparungen eingesetzt werden und gegen Erschütterungen bzw. Beschädigungen bei einem Unfall geschützt sind, und daß die Trimmung des Modellhubschraubers nicht durch einen unsachgemäßen Einbau beeinträchtigt werden kann. Außerdem ist die Erstellung eines Rumpfes aus nur zwei massiven Halbformen wesentlich einfacher und schneller durchführbar als bei bisher bekannten Modellhubschraubern. Die Erfindung ermöglicht es auch handwerklich weniger begabten Personen, sich mit diesem Hobby zu beschäftigen.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.

Der Vorteil von Styropor besteht darin, daß es leicht zu verarbeiten ist, ein geringes spezifisches Gewicht hat und über eine große Schlagfestigkeit zum Schutz der Einbauteile verfügt. Außerdem kann es so ausgeführt werden, daß es resistent ist gegen die Treib- und Schmierstoffe.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.
Zur Verbindung der beiden Halbformen miteinander wird die Verwendung von Dübeln und Gummiringen vorgeschlagen. Dabei sind die Halbformen mit Dübeln, die aus dem Rumpf heraus nach außen ragen, versehen, beispielsweise Holzdübel, die in geeignete Aussparungen in die Halbformen eingesetzt und verklebt werden. Im zusammengesetzten Zustand werden dann Gummiringe, wie sie im Modellflugzeugbau üblich sind, so an den Dübeln eingehängt, daß die von den gedehnten Ringen ausgeübte Rückstellkraft die beiden Halbformen zusammenpreßt. Der Vorteil besteht darin, daß die Halbformen voneinander lösbar sind, und so beispielsweise der Motor für Wartungsarbeiten leicht zugänglich ist.To connect the two half-forms with each other the use of dowels and rubber rings is suggested. 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. The advantage is there in that the half forms are detachable from each other and, for example, the engine for maintenance work is easily accessible.
Prinzipiell ist es möglich den Rumpf z. B. quer zur Längsachse oder durch einen sonstigen beliebigen Schnitt zu teilen. In dieser Ausgestaltung wird vorgeschlagen den Rumpf in zwei Halbformen, die im wesentlichen symmetrisch zu einer senkrechten Ebene, die durch die Längsachse des Hubschraubers verläuft, aufzuteilen, insbesondere zu der senkrecht stehenden Ebene, so daß er aus einer rechten und einer linken Hälfte zusammengesetzt wird. Geringfügige Unterschiede in der Symmetrie können sich durch das Anbringen verschiedener Aussparungen für die Einbauteile ergeben. Der Vorteil dieser Ausgestaltung liegt darin, daß alle Einbauteile im Rumpf inneren leicht zugänglich sind.In principle it is possible to use the fuselage z. B. across Longitudinal axis or by any other To share cut. In this embodiment proposed the hull in two half forms, which in the essentially symmetrical to a vertical Plane through the longitudinal axis of the helicopter runs to divide, especially perpendicular to that standing level so that it is from a right and a left half is put together. Minor Differences in symmetry can yourself by making various recesses for the built-in parts. The advantage of this Design is that all built-in parts in Fuselage interior are easily accessible.
Eine vorteilhafte Ausgestaltung der Erindung besteht darin, daß der Rumpf über ein Rohr zur Aufnahme der Heckrotorwelle verfügt, in dem die sich drehende Antriebswelle des Heckrotors geführt wird, so daß sie nicht direkt in Kontakt mit dem Material der Halbformen treten und es beschädigen kann. Dabei ist es beliebig, ob die Halbformen das Rohr vollständig, d. h. bis zum Heckrotor, umschließen, oder ob das Rohr aus dem Rumpf herausragt. Die Ausstattung des Rumpfes mit einer solchen Vorrichtung sowie die Auswahl eines dafür geeigneten Materials ist dem Fachmann möglich.There is an advantageous embodiment of the invention in that 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. Here it is arbitrary whether the semi-forms the pipe completely, d. H. to the tail rotor, enclose or whether the pipe protrudes from the fuselage. Equipment of the fuselage with such a device as well as the selection of a suitable material is possible for the specialist.
Zur Erhöhung der Stabilität des Hubschrauberrumpfes wird vorgeschlagen, die Halbformen mit Versteifungen zu versehen, deren Beschaffenheit erfindungsgemäß unerheblich ist. Sie sollen die Stabilität des Rumpfes erhöhen bzw. die Verwindung des Hubschraubers um die Längsachse verringen. Insbesondere wird vorgeschlagen, die Halbformen mit Versteifungsrippen zu versehen, d. h., daß an den Halbformen Rippen bzw. Stege angeformt sind. Sie können in dem Fachmann bekannter Weise während der Herstellung als Bestandteil der massiven Halbform ausgebildet, oder nachträglich, z. B. auch aus anderen Materialien bestehend, angebracht werden.To increase the stability of the helicopter fuselage it is proposed to use 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. In particular suggested 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.
