Most modelers relation to schematic gliders and rezinomotornaya, to put it mildly, condescending: “three stick a piece of tissue paper and even after running not immediately fall to the ground!”. But such models, which will meet in almost every circle, was designed almost in the beginning of the century and has reached our days unchanged. Not our if fault is that? It may be worthwhile to try to create something more modern, overcoming the neglect of “chemcam”?
Today we offer our readers a model of two-stage missiles S1C and S2B, developed by a member of the team To, Butrova. Its peculiarity is the unusual principle of resetting the second stage after working MRD — is it due to breaking parts of the split housing this stage.
Typically to achieve the necessary alignment of heavy fighting model of the micro retracts in the cutout of the front edge of the wing. This leads to some loss of strength and complication of manufacturing technology, and access to the engine for maintenance is much more complicated. So I had the idea to implement the idea of forward-swept wing is given in the “M-K” № 7 for 1988. Front and rear edge of the wing of the new models are made by gluing pine veneer (thickness of 2-1. 5 mm) on the mandrel with the subsequent cutting on a lathe to the required edge thickness. The bonding is conducted on the PVA. Mandrel is more practical to manufacture of chipboard, and in the mounting position and clamp the veneer pack to apply a lacquer coating to facilitate removal of the part after drying.
Readers rezinomotornaya a replica of a historic aircraft “Moran-G” in which famous Russian pilot P. N. Nesterov first in the world made air RAM .The model was created in two versions — “full” copy with a boxy fuselage and polyopia with a contoured fuselage. To achieve a satisfactory flying qualities, had to go to small deviations from the proportions of the prototype aircraft. The models are made entirely from common materials, the main of which was melkosortnyj packing foam density of 0.05—0.06 g/cm3, chopped termolabil for plate thickness 0.5—1.5 mm. By weight parameters of the model are comparable to the best balsa models. To make their students of 6-7 grades. Choosing a simple plane as a prototype to copy allows to make emphasis in students ‘ work and not to simulate individual elements, and the manufacturing quality of the device.
Timer “school”, published in “M-K” № 12 in 1986, is a unique combination of reliability, service life and good flight properties. Now that our group operated two such machines, we can safely say that. It should be noted that “loss” in sports-related accidents time, unfamiliar to us. Believe it or not, in such main circuit, accurate Assembly of the frame on the plasticized resin and Mylar covering to break the model, even with strongly uprated engine is almost impossible! Of course, strength isn’t everything. But the important and time-saving Modeler, especially spending on “nasty” repairs. So, now all the “repairs” been reduced to mere convergence of the split nodes. At the same time with extraordinary strength achieved and very high rigidity of the machine, which is extremely important for engine model.
The race for sports results brought in the “school” subclasses of automodelisme to professionalize technology. To replace the familiar MK-17 came potentially more powerful engines of the brand MDS. However, if the “Juniors” were already known methods of dealing with their numerous “ills”, the new motors asked the number of problems and issues. But anyway, after a considerable number of specific modifications of MDS reserves its power MK-17.
Wish to give modelers another way to give the sail models naturally convex shape. This method is simple, but perhaps more effective than others. Its essence is as follows.
The Rules on the self-similar sports of the USSR, issued in 1989, a new class: E-5. With the technique permitted by the rules for competition in this class, athletes unfamiliar, and it sharply differs from the known. Try to determine the search paths of optimal solutions racing models-replicas and purpose of this article.
Elegant appearance, ease of fabrication, lack in construction materials in short supply, good flight characteristics are qualities that distinguish a schematic model of the airframe designed in the laboratory of aviation technology rut of Kazakhstan. Such models young Almaty residents repeatedly became winners of various competitions. Maximum results in all rounds is not uncommon when using the proposed “schematicity”. And flight characteristics of the glider was so high that it had to be equipped with a matchlock device forced landing. Without it, many models disappeared in terms.
In June 1990, Kiev stadium DOSAAF “the Seagull” for five days has become a kind of Baikonur. Here were the start of the eighth world championship on rocket and space models. Athletes from 11 countries played awards of the world championship in seven classes flying of model rockets.
