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.
“BEGINNERS”: A UNIVERSAL SOLUTION
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.
A kite is considered to be the grandfather of modern aircraft. This harness motorless soaring leader was the first aircraft in the so long ago, when there was still such thing — aviation. Unfortunately, in the future, kites were replaced by more udachlivey fellow sky — models of gliders and planes.
High speed RC model with electric drive is very popular with modelers-but-wickow and veteran athletes. This to a large extent contribute concise external form guide-registerof prototype that simplifies the design, allows you to make models from a variety of materials and used in the manufacture of a variety of technological methods — depending on experience, availability of certain materials and finished components (engine, onboard equipment and batteries).
The search for new solutions before the next sports season has led our members to very unusual for present-day design. In a subclass of HH-0.2 is now dominated by specialized yacht model. Basically it is a catamaran with a rigid sail-wing or newfangled pyramidal sailing tooling used again in mnogotochechnykh. However and those and others are clearly expressed signs of directions of designing of sports projectiles that have little in common with real yachts. So we tried to go back to the models one-korpusniki, refitting their sailing rigging. The fact that the classical scheme of a cutter with mainsail and staysail in its simplest initially losing performance in connection with birth defects tractive effort of the sails. We have used the so-called stukeley scheme (often referred to as the L-shaped mast). It has much better properties, as it provides the most Agnolo element snap — grotto — optimally and in a wide range of settings of the sails. Do note that designs based on technically sophisticated “bells and whistles” (like rotary wing masts and the like) are generally not considered when creating the model students all that’s out.
In issue 9 of our magazine, a story was published with the exhibition NTTM-2011. Despite the rather significant amount, it was told only about transport designs, developed the student creative groups and young inventors. Side by side with them demonstrated their achievements and more young modelers and designers. Their work represented a variety of directions of scientific-technical creativity: from simple scale models to innovative technologies and projects of space systems. And it would be unfair not to tell about them.
When among students who have mastered only the basics of the original automodelisme, comes to talking about the class of simple machines, rubber motor, it is submitted immediately think “sophomoric”. They say, in the age of radio, heavy duty electric motors and internal combustion engines are very popular and widespread at the time the class is now an anachronism and good except for exploring the world of car.
For the last four years on the initiative of the heads of model aircraft clubs in the town of Zheleznodorozhny in the Moscow region competitions school students in the new class of resinator indoors. If you compare these models with others, participating in competitions, for example, a glider and a helicopter “Fly”, the proposed resonatory more complex. Therefore, it can be recommended for the manufacture of the guys visiting the club for the second year.
Throwing gliders enjoy enduring popularity among modelers — both beginners and experienced. The fact that these miniature models have performance more solid aircraft — they are capable of when you start hand to gain a height of over 20 m, hold steady to the “terms” and sometimes too far from the start.
