Abstract

Airplane for the practice of model airplanes by radio control with different flight configurations, of the type that incorporate a fuselage with two front wheels, a rear wheel, two tail planes and a rudder, as well as the corresponding engine and its system radio control, characterized in that it incorporates a low, short wing, of constant profile and topped by its free ends in respective flat surfaces provided with fixing means with removable character for different wing ends, equipped in turn with complementary coupling means and these wing ends being of substantially different lengths, the fuselage also having in its upper area coupling means for fixing uprights, also with a removable character, of a high wing with cut ends, similar to the lower wing described and also equipped of fastening means for the different types of wing end mentioned, all in a way that different combinations the aforementioned elements give rise to low-wing aircraft or biplane aircraft, with different wing sizes.

Object of the invention

The present invention relates to an airplane for the practice of radio-controlled model aircraft type of constitute scale replicas or semi-scale real aircraft, although they can also obey specific or exclusive designs, and that once mounted and ready to fly can be controlled from the ground for the realization of different types of flights and acrobatics.

The object of the invention is to get a plane able to change extraordinarily quickly and easily your configuration, in order to offer flight qualities substantially different, such as aerobatic flights with higher or lower speed, safe flights at low speed, flights gliders, etc.

Background of the invention

At present there are numerous in the market models for the practice of model aircraft radio-controlled, presented in different formats such as raft wood mounting kits and plywood, models already finished and ready to fly, etc.

Every model airplane owner usually has more than one plane and usually one or two of them usually carry on the flight field, sometimes due to transportation, given its volume, and sometimes many for not having greater availability in this regard, due to Cost of these planes.

So and to get the flight types to that has been mentioned before it is necessary to have many other planes, which means a very considerable investment, which for many cannot be assumed, while still not existing this economic problem, having a considerable number of airplanes with different types of flight, supposes the need to have at the same time a very considerable space for storage, and the already pointed problem of impossibility of transporting more than one or two devices to the flight field.

Description of the invention

The airplane for the practice of aeromodelling that the invention proposes resolves in a fully satisfactory manner the problematic previously exposed, in the different aspects commented, since with an investment slightly greater than the necessary to acquire a conventional plane and with an occupation of space both in storage and transport situation also similar, the user can have multiple times types of aircraft, with different flight characteristics, without more than the incorporation, elimination or replacement of certain parts of his unique plane.

For this and more specifically, the plane that it is recommended it is constituted from a base piece that integrates the fuselage, with its rudder, tail planes, wheels and a pair of short low wings, said fuselage also integrating the engine and corresponding radio control means, with the particularity of that said fuselage incorporates at a higher level means of interlocking for the uprights of an upper wing, which consequently it can be fixed to the fuselage or be maintained in reservation depending on whether you intend to fly with a biplane plane or no.

On the other hand the mentioned low wings count in its ends with coupling means for complementary wings, which from now on will be called wing end, of different lengths, namely extremely short wing ends for acrobatic models, intermediate length for models "sport" and longer for glider models.

The coupling / decoupling of all these elements are carried out by simple tongue and groove, which allows a extraordinarily quick and easy maneuver to change type of airplane, from the pieces described.

It is achieved in this way that from a Unique plane, with a few accessories that barely enchant your cost, by assembling one or other complementary parts, quickly and easily get a low-wing aircraft aerobatic, low-wing "sport", high-wing acrobatic, wing high "sport", acrobatic biplane, "sport" biplane or motorsailer, since the wing ends mentioned can not only be mounted on the low wing but also on the high wing when it is incorporated into the plane.

Description of the drawings

To complement the description that is being performing and in order to help a better understanding of the characteristics of the invention, according to a preferred example of practical realization of it, is accompanied as an integral part of said description, a set of drawings where with character Illustrative and not limiting, the following has been represented:

Figures 2 to 8.- They show different types of aircraft obtained by assembling certain parts of the previous figure.

Preferred Embodiment of the Invention

In view of the figures outlined and in particular of figure 1, can be seen as the airplane that preconiza is constituted from a base piece that configures the fuselage (1), which integrates the engine (2) and the means of radio-control, the front wheels (3) with their corresponding arms, short low wings (4), the rear wheel (5), the tail planes (6) and the rudder (7), but with the particularity that the low wings (4) mentioned have a constant section to its free end (8), topped off in a perfectly perpendicular plane with respect to the wing axis (4), ends (8) equipped with tongue and groove coupling means (9) for different wing ends (10, 11 and 12), different because of their different length, but all equipped with means of complementary tongue and groove coupling (13) (9) that have low wings (4) in solidarity with the fuselage (one).

These three wing ends (10, 11 and 12) are selectively attachable, depending on the type of flight, both at low wings (4) like a high wing (14), which is also attachable with optional character to the fuselage (1) with the collaboration of uprights (15) tongue and groove pluggable in accommodation (16) in the area top of the fuselage (1), as is also visible from the observation of figure 1.

Although in the representation of the repeatedly cited figure 1 three wing ends (10, 11 and 12) appear for each end of the low wing (4), in practice the number of ends wing will be double since there is the possibility of coupling the same wing end to the low wing (4) than to the high wing (14), to the object of provide the plane with maximum versatility.

According to this structuring and as to your once it follows from the observation of figures 2 to 5, you can Obtain a plane provided exclusively with low wings with high acrobatic capacity and higher or lower speed, as shown Figures 2 and 3, or obtain a biplane of upper and lower wings dimensionally equal, as shown in Figure 4, or wing higher than the lower ones, as shown Figure 5, among many other possibilities resulting from different combinations between wings and wing ends available.

Claims (3)

1. Airplane for the practice of radio control aeromodelling with different flight configurations, of the type that incorporate a fuselage with two front wheels, a rear wheel, two tail planes and a rudder, as well as the corresponding engine and its system of radio control, characterized in that it incorporates a low, short, constant-profile wing and topped by its free ends on individual flat surfaces provided with fastening means with detachable character for different wing ends, in turn provided with complementary coupling means and these wing ends being of substantially different lengths from each other, the fuselage in its upper area also having coupling means for fixing uprights, also with removable character, of a high wing of cut ends, similar to the low wing described and also provided of fixing means for the different types of wing ends mentioned, all in such a way that different combinations Ations between the aforementioned elements give rise to low-wing aircraft or biplane aircraft, with different wing sizes. 2. Airplane for the practice of radio control aeromodelling with different flight configurations, according to claim 1, characterized in that the coupling means for the wing ends and for the high wing consist of tongue and groove elements of pressure coupling. 3.
