Introducing radio controlled model aircraft for training flights. The prototype was popular among modelers from different countries models “Corkscrew” (Corkscrew) is an American athlete Stuart L. Richmond. The appearance in the sale of grooved balsa plates and rails (at least in specialised stores) as well as excellent flight performance and simplicity of execution “Corkscrew” became the incentive to further improve the original scheme.
Despite market saturation, radio-controlled car and their simplistic and relatively cheap likes — RC avtokraski, EN-route kits are all also attract the attention of fans of sports automodelisme. I must say that the model market offers a lot of interesting tracks for: here and small motors with samarium-cobalt magnets that develop a power of 100 watts, and painted the inside of the one-piece shell-the housing of Iksanova film, and even finished chassis of various designs. However, the desire to make a completely homemade design is truly indestructible. The more that the advantages of such models include their relative simplicity, speed of production, and with the use of very simple equipment — literally “on the knee”.
The increase in the number of athletes, creating a model with a remote control, is not to the detriment of the adherents of the cord. The fact that even “radiosporten” make their first steps in aircraft modeling, holding the control stick Assembly. However, before you build a model internal combustion engine, it makes sense to make the apparatus easier — non-motorized. This will enable the beginner to master the piloting skills necessary for the management of more complex kordovye models. Moreover, this no-motorboat can make even the elements of aerobatics like inverted flight and loop.
Adherents of certain types of modellers rarely use the design solutions and technological methods inherent in other areas of technical creativity. And it is in vain. The proof is a universal module that can with the most minimal improvements to turn into a car, air or sudomodel. As can be seen from the drawings, the module is a four-wheeled the trike with engine MK-17 “Junior”.
The proposed model is a vivid example of technical creativity of Moscow’s leading athletes-taketomo-delicto that three years in a row became Champions of Russia in this category of high-rise models. One of the athletes — M. Stepanov, who won last year. Our story — about the design of his sports equipment.
To create the body of the car, aircraft or boat, as you know, very advanced technology is Vileika of fiberglass using as a binder a polymer resin — epoxy, polyester and the like. The designer of the model always faces the inevitable choice: which of the options vyklicky to use it? You can select the matrix method of forming, providing a high quality surface without laborious finishing and allowing a “replicate” of the body, which is very useful in the manufacture of models in clubs or circles. However, we have to spend a lot of time on the first production of the master model, and then matrix.
In recent years, almost all types of modeling in our country is clearly a noticeable trend away from pure sports fields design in the direction of almost amusement equipment. Most obviously this applies to cord classes. Therefore, to force the students to do, for example, high-speed gliders of the group A difficult. Your imprint is applied and undoubtedly changed the psychology of the modern boys and the impact of adequately presented in the catalogs, modelistica stores and in the RC circles, and another that looks more attractive technology.
At the Russian championship 1997, she brought a gold medal to its author, the Moscow athlete M. Stepanov. According to many experts, this model is the Acme of perfection of the sports projectile of this class. Its mass (without a parachute and MRD) in just 3.5 g model in the widely known techniques of moulding of the fiberglass. The thickness of the applied fiberglass 0.25 mm. case and a fairing carefully crafted wall of uniform thickness. Tail part of the body in length 100 mm smoothly into the cone, and then into the cylinder with a length of 35 mm and an inner diameter slightly larger than 10 mm. In the same place, reinforced wire latch locking motor from inadvertently shooting when triggered, expelling charge.
Despite various difficulties faced by modelers, RC aircraft are still interested in this most complex kind of modeling. Everyone who chose a specific type of equipment, immediately the question arises a considerable difficulty: how to lay model? The solution of this problem on the proposed development. The main principles which form the basis in the design of this RC model, steel of sufficient simplicity, accessibility and, most importantly, the high performance characteristics at different flight speeds and specific loads.
In one of the rooms “M-K” in the report from the championship of Russia on model rockets, I noted the rocket plane category S4 Nikolay Tsygankov team in Murmansk region. I must say that the chosen scheme with a large wingspan (about 950 mm) and elongation of about 20 provides good performance as well. This contributes to the convexo-concave profile of the wing, and elliptical shape of the bearing surface when viewed from above. And external contours of the tail look perfect. All this allows to a minimum to reduce aerodynamic drag. Originally decided N. Tsygankov and the problem of drag reduction during takeoff model. He used double-folding “ears” (consoles) of the rocket and to prevent the occurrence of flutter of the fixed wing is folded in three points (instead of the usual – in two points), securing the third hook-latch on the tail boom.
