Descrizione di INVENZIONE INDUSTRIALE Description of INDUSTRIAL INVENTION
CORPO CENTRALE DI UN ELICOTTERO RADIOCOMANDATO CENTRAL BODY OF A REMOTE CONTROLLED HELICOPTER
Il presente trovato ha per oggetto il corpo centrale di un elicottero radiocomandato. The present invention relates to the central body of a radio-controlled helicopter.
Allo stato attuale, in ambito di elicotteri radiocomandati, con corpo centrale sì definisce il telaio capace di supportare tutte le funzioni più importanti dell'elicottero. Detto corpo centrale supporta il motore, la trasmissione di potenza, i cuscinetti per l'asse rotore principale, gli attuatori che gestiscono la geometria della testa rotore. Al corpo centrale inoltre si collega anche la trave di coda. Attualmente la tecnica realizzaiiva per rispondere a tutte queste esigenze è accoppiare una a fianco all'altra due lastre sottili opportunamente intagliate, normalmente in alluminio o materiale composito, unite poi con vari elementi trasversali bloccati con accoppiamenti filettati sulle lastre stesse. At present, in the field of radio-controlled helicopters, a central body defines the frame capable of supporting all the most important functions of the helicopter. Said central body supports the motor, the power transmission, the bearings for the main rotor axis, the actuators that manage the geometry of the rotor head. The tail boom is also connected to the central body. Currently, the technique used to meet all these needs is to couple two suitably carved thin plates side by side, usually in aluminum or composite material, then joined with various transversal elements locked with threaded couplings on the plates themselves.
L'insieme degli elementi trasversali e delle due lastre risponde alle esigenze di supporto descritte in precedenza. The set of transverse elements and the two plates responds to the support requirements described above.
Il sistema così concepito risulta però complesso. Il tempo di montaggio degli elementi trasversali è alto in quanto tutto viene assemblato attraverso accoppiamenti filettati. Anche la manutenzione è di conseguenza complessa. Per esempio in seguito ad una caduta del modello è facile danneggiare una delle due lastre con conseguente necessità di smontaggio di gran parte dell'elicottero per la sua sostituzione. The system thus conceived is however complex. The assembly time of the cross elements is high as everything is assembled through threaded couplings. Maintenance is consequently also complex. For example, following a fall of the model it is easy to damage one of the two plates with the consequent need to disassemble a large part of the helicopter for its replacement.
Lo scopo del presente trovato è semplificare la soluzione, rendendo molto più agevole il montaggio e la 5 manutenzione stessa. The object of the present invention is to simplify the solution, making assembly and maintenance itself much easier.
Si raggiunge tale scopo andando a realizzare un gruppo compatto interamente in materiale di lega leggera capace di supportare autonomamente tutte le funzioni di cui sopra. Ottimizzando il lay-out dei vari componenti seguendo questa 10 soluzione si riesce a realizzare un corpo centrale molto compatto che soddisfa tutte le esigenze. This purpose is achieved by creating a compact unit entirely in light alloy material capable of autonomously supporting all the above functions. By optimizing the lay-out of the various components following this solution, it is possible to create a very compact central body which satisfies all needs.
Le caratteristiche tecniche del trovato, secondo i suddetti scopi, sono chiaramente riscontrabili dal contenuto delle rivendicazioni sotto riportate ed i vantaggi dello 15 stesso saranno evidenti nella descrizione dettagliata che segue, fatta con riferimento ai disegni allegati, che ne rappresentano una forma di realizzazione puramente esemplificativa e non limitativa, in cui: The technical characteristics of the invention, according to the aforementioned purposes, are clearly verifiable from the content of the claims reported below and the advantages of the same will be evident in the detailed description that follows, made with reference to the attached drawings, which represent a purely exemplary embodiment. and not limiting, in which:
La figura 1 mostra una vista in prospettiva di tutto 20 l'elicottero; Figure 1 shows a perspective view of the whole 20 of the helicopter;
La figura 2 mostra una vista in prospettiva esplosa dove viene messo in evidenza il corpo principale separato dal resto dell'elicottero; Figure 2 shows an exploded perspective view where the main body separated from the rest of the helicopter is highlighted;
- La figura 3 mostra una vista in prospettiva esplosa 25 di dettaglio del corpo centrale secondo l'invenzione; Figure 3 shows an exploded perspective view 25 of the central body according to the invention;
La figura 4 mostra in modo particolareggiato una vista in sezione sempre del corpo centrale; Figure 4 shows in detail a sectional view of the central body;
Conformemente alle figure dei disegni allegati, e con particolare riferimento alla figura 2, al corpo centrale 30 dell'elicottero (1) vengono uniti il gruppo di coda (2) e il gruppo carrello e batteria (3). In accordance with the figures of the attached drawings, and with particular reference to Figure 2, the tail unit (2) and the trolley and battery unit (3) are joined to the central body 30 of the helicopter (1).
Entrando nel dettaglio costruttivo e con riferimento alle figure 3 e 4 il corpo principale secondo l'invenzione è realizzato unendo due elementi (4, 5} di forma opportuna per supportare e gestire tutte le funzioni. Entering into the construction detail and with reference to Figures 3 and 4, the main body according to the invention is made by joining two elements (4, 5} of suitable shape to support and manage all the functions.
Con riferimento alla figura 3 per cercare la maggiore compattezza possibile gli attuatori del comando rotore (6) sono disposti direttamente attorno al suo asse (12), ruotati tra di loro a passo di 120° sul piano orizzontale e orientati in modo da ingombrare il meno possibile in direzione dell'asse rotore (12) stesso. With reference to Figure 3, in order to seek the greatest possible compactness, the actuators of the rotor control (6) are arranged directly around its axis (12), rotated between them at a pitch of 120 ° on the horizontal plane and oriented in such a way as to encumber as little as possible. possible in the direction of the rotor axis (12) itself.
Nella zona (9) è prevista la sede per l'unione al gruppo di coda ( 2 - figura 2). In the area (9) there is the seat for joining the tail group (2 - figure 2).
Nella zona (10) è prevista la sede per l'unione al gruppo motore (11). In the area (10) there is the seat for the connection to the motor unit (11).
Con riferimento alla figura 4 gli organi della trasmissione (7) sono impachettati dai due elementi (4, 5) in modo da poter collocare i cuscinetti (8) all'esterno di detti organi (7) massimizzando la rigidezza della trasmissione . With reference to Figure 4, the transmission members (7) are packaged by the two elements (4, 5) so as to be able to place the bearings (8) outside said members (7) maximizing the rigidity of the transmission.
In sintesi il trovato sopra descritto consente di ottenere un corpo principale estremamente compatto e solido. Tutti i componenti importanti sono uniti a lui e quindi è garantita la massima rigidezza dell'assieme. In caso di caduta del modello il corpo cosi concepito risulta in sostanza indistruttibile. In summary, the invention described above allows an extremely compact and solid main body to be obtained. All important components are joined to him and thus the maximum rigidity of the assembly is guaranteed. If the model falls, the body thus conceived is essentially indestructible.
Il trovato così concepito è suscettibile di numerose modifiche e varianti, tutte rientranti nell'ambito del concetto inventivo. Inoltre, tutti i dettagli possono essere sostituiti da elementi tecnicamente equivalenti. The invention thus conceived is susceptible of numerous modifications and variations, all of which are within the scope of the inventive concept. Furthermore, all the details can be replaced by technically equivalent elements.
