PNEUMOTACHOMETER-SAILBOAT

PNEUMOTACHOMETER-SAILING SHIPFilled with wind-taut sail… This age-old symbol of romance will not leave anyone indifferent. And there is nothing surprising in the fact that the number of sailing enthusiasts every year increases. Today they are much more than you can take the yacht clubs, so work on creating Amateur sailing ships many have no qualified advice.

WHOLEHOG

VOENOHOTIt is not similar to any of the existing transfer machines. Outside no wheels, caterpillars — not at all friction parts, gland seals. Only the bottom constituting an elastic pad, flexible: can be bent, forming a traveling wave. Wholehog designed and built by the Lipetsk engineer Yu. V. by Arpinum. Projection wanaheda given at different phases of movement. The kinematics of this machine are not very easy to understand. At first glance it seems that, even raised ka solid surface, it does not budge, no matter how much I ran her to the bottom of the wave. In fact it is not.

MAGNETIC LEVITATION

MAGNETIC LEVITATIONThe one who had the opportunity to disassemble a conventional magnetic latch for a door, must have noticed how strong the magnet used in it. This leads us to the idea to use magnets instead of springs in the front suspension trace model. This is done as shown in the figure. Frame our model — box, welded from sheet metal, rigid and light. Front suspension — oscillating arm transversely of the wire. Axle nuts attached to the fists, bent in the shape of a triangle made of tin. The wheel turned, the tires of sponge rubber.

CORD AIRBOAT

CORD HYDROPLANEToday our story is about the original high-speed input developed in the circle of children’s club “Iskatel”. Designed for the most advanced scheme, it contains a number of technical innovations that may be of interest to experienced athletes. Cord hydroplane class A1 favorably known development the lack of scarce or toxic in the materials — balsa, glass and carbon fiber reinforced plastics, which gives the possibility of recommending the model for the building even in the school clubs shipmodelbuilding. The use of standard domestic engine CSTOM KRAS ensures the implementation of fitness standards on the level of a first level up to the candidate master of sports.

NOT WORKING? MAKE!

NOT WORKING? To MAKE!On the shelves of the “Young technician” to replace the outdated MK-12V has received a new domestic micro-DISTRICT is 2.5. However, unfortunately, the present mass model was not too successful. The DISTRICT bears no comparison even produced a long time ago “twelfth” with the barrel red jacket.

AND AGAIN NUTRIT

AND AGAIN NUTRITOn the mechanisms used to its movement due to inertia of the rotating imbalances of the journal “modelist-Konstruktor” wrote more than once (see number 5 and 12 for 1975, No. 6 1976, No. 3, 1978). The publication aroused great interest among readers, so we return to this topic. The amazing ability of nutricola, or inertsioidov, as they are called — to move without using wheels, tracks or air screw — continues to captivate enthusiasts-inventors. And although the effectiveness of this type of propulsion is not yet well-known competitor, perhaps one of the most perfect models of nutriton will be a prototype of the future transport. And while we offer to your attention another scheme inertsioidov mover. Its author — kas reader from the city of Ryazan Alexander Mikhailov.

SEEDER-DORADCA

DRILL-DORADCAOn private land, perhaps only a decorative grass — raygrass — tracking, scattering the seeds. The vast majority of annual flowers and vegetables planted in rows: so the plants are easier to handle and feed. But since seeds are small, often the shoots are too dense. You have to spend a lot of time pulling, away, by the way, is harmless to the root system.
