High summer in the polar Urals. Together with the chief of the survey party we were returning from the upper reaches of the river Secure. Breaking the latest on the slope Qurum, saw an unusual procession: animal-hunting trail that winds its way literally along each river, even in the taiga areas, slowly moving tanned guys, pushing a loaded cart. And although they were on a narrow “quilted” and jumped up and down on the protruding roots, the group easily went ahead. Truck, rather narrow and rather short, well passed among the bushes and young growth, fitting into the “dimensions” of the trail. “Wouldn’t it be easier to fit everything into a backpack, than to drag with itself still tapezco?” — we asked. The answer was unexpected:
“Superfluous here — just the wheels, the rest belongs to boats: they are taking themselves”. Indeed, after a careful consideration of all elements are parts of a Dinghy. Even the handles were bars of the bulwarks.
Judging by editorial mail, does not weaken the interest of students of avtomodelistov to the micro machines of the class AL with actuator. The widespread availability of sports equipment, possibility of carrying out of competitions at any time of the year to attract new boys into the ranks of the followers of automodelisme.
All wheelchairs domestic production have a primitive manual transmission.
Surfers are very convenient to carry pas the roof of the car, strengthening on the trunk. What about to those who have not got such a vehicle and has so far only bike. We propose to use a simple truck-trailer. For its production you will need two Bicycle wheels, a metal strip 5X30 mm and rods with thread for lodgements.
Truly consistently popular models class F2D. The possibilities of creative search is far from exhausted, and that no season, designers offer new solutions. An example is the model developed in aeromodelling lab at Home technical creativity of youth, acting at the black sea shipbuilding plant in Nikolaev. Modern scheme (the wing with the recommendations in the ravine tail plane rudder) processed under readily available materials, and high performance characteristics, vitality and great adaptability Assembly and repair had been preserved. Speaking with such equipment at the Republican youth games, a crew of young athletes DTM — Swiderski A. and S. Zhigunov — has become one of the winners of the competition.
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.
To use a bike instead of round sprocket Ellipso suggested in 1892 Professor V. Prusakov. He decided to put the rods along the minor axis of the ellipse that has allowed more efficient use of the power of the cyclist. Experiments have shown that even an inexperienced rider on a machine with the elliptical sprocket expends energy approximately 30% lower than on moving with the same speed filemashine with a round sprocket. And according to the American engineers, the use of oval zubchatki increases the average speed of a cyclist by about 14%.
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.
