Aware that in the modern mass automodelisme in a very objective and not very reasons there is a critical situation to the attention of athletes, club Directors, and especially the workers of the Federation of auto modeling sport of Russia unusual material. It is dedicated to the development of a new concept (hopefully, very promising!) class car — unmanaged vetrogonov.
In favor of new self-similar sports equipment says a lot. It is a potential zrelischnost and highly attractive class vetrogonov, availability of production land sailers, not comparable with any other self-similar class. Probably not a sin to think about the environmental aspects of the question of constructing non-motorised vehicles. In addition, attracted by the opportunity to hold competitions of any rank with autoproclamate on non-specialized platforms and tracks (starting from track or even grass stadium field and finishing asphalt or concrete roads).
Is one of the important factors such as the sharp increase in the educational opportunities plan, the proposed class of car. We will not dispute the existence of the same have already known “schools of design”. However, in fairness, we note that in the past the vast majority of cases, technology has established the used character, and the real innovations in it affect only the nodes or improvement of manufacturing technology of parts.
of view of technical knowledge) is not only the making of new sports equipment, but also the breadth of knowledge required in the future to build any such machine. After all this, you will need information from aerodynamics, aircraft design techniques, information on calculation and design of ships and yachting record.
The only thing I would like to ask those enthusiasts that decide to develop rules proposed by the magazine “modelist-constructor” of the class (and the editorial Board hopes that such exist!),— not to limit designers of any age hard technical terms. A useful example can serve as rules for ship models-yacht class HH (or similar “Junior”), where, in fact, only a limited area of sailing arms.
R and S. 1. Sailing car classic type:
1 — saw the wind feather of the machine of course (no roll model required only for unloading bearing unit), 2 — hour slot of the course on the bearing Assembly, 3 — V-shaped wind-feather machine, 4 — rear brace of the mast 5 is located aft of the ballast weight, 6 — Grot, 7 — lats (required if high elasticity of the sail material); 8 — mast (tapered wooden rail), 9 — front brace-vant mast, 10 — staysail, 11 — boom-mainsheet (adjustable), 12 — element systems tension braces, 13 — front wheel, 14 — strap with several holes for the reversible adjustable position of the lower end of the mast, 15 — mainsail-mainsheet (adjustable), 16 — mainsail, 17 — rear castor wheel (connected through the pylon and thrust with swivel stand automatic rate; the reverse relationship type), 18 — bracket avtomet, 19 — T-shaped body (wooden slats), 20 — cross bar housing (wooden plank).
R and S. 2. Sailing the car with a pyramidal type of rigging:
1 — rear castor wheel (connects to a long rod with a horn mast sailing self-aligning system using axis of rotation and the same horn), 2 — wild boar axis wheels,3 — stabilizatory plate self-aligning sailing system, 4 — rear brace of the mast 5 bracket stabilizer-tion plate, 6 — Parus pyramidal type, 7 — mast 8 — front brace-vant mast, 9 — front wheel, 10 — housing, 11 — bracing, 12 — boom 13 — longitudinal plank strengthening of the body, 14 — simulation of the cockpit and “driver”, 15 — pull connection system controls the rear wheel 16 is a flat body frame, 17 — possible position of the mast if the wind direction right, 17A — similarly, on the left.
(Characteristics of pyramidal sailing arms on models with the principles of its construction and commissioning can be found in the article “Yacht-Pramod” in No. 3, 1990.)
R and S. 3. Sailing the car with a rigid sail:
1 — stabilizatory plate self-aligning sailing system, 2 — bracket stabilizatory plate 3 is a rigid sail-wing is bent convex profile (used when wind direction to the left; when the wind is right is the same sail is a wing, but the reverse profiling), 4 — axis of rotation of the sailing system, 5 — balancer (used only when needed to reduce stress in the bearings of the axis of rotation of the sailing system), 6 — simulated cockpit, 7 — pull machine control (retention) rate, 8 — axis of rotation of the front wheel with a horn, 9 front swivel wheel fairing, 10 — case (wooden plate) 11 —Cabana boy 12 —a cover of the housing for mounting the bearing Assembly (2 PCs), 13 — rear wheel fairing, 14 — transverse rod.
R and S. 4. Diagram of the basic layout of the sailing performance.
Compliance with given proportions provides equal static load on all three wheels, that is necessary for the stability of the course at the specified rate. The principle is similar to the balancing of the yacht’s center of lateral resistance of the underwater part.
R and S. 5. The scheme of violation of static balancing with wind ia sail model.
R and S. 6. Diagram showing the principle of occurrence of the vector quantity apparent wind:
A model at the beginning of the dispersal; self-aligning sailing system exhibited under the most advantageous angle to the wind vector, the thrust of the sails is directed mainly forward; B — model at maximum speed, sail samostroya in the most advantageous position relative to the apparent wind vector, and the thrust is mainly directed away from the motion vectors of the model.
Due to the very high relative speed sailing car as an analogy, it is necessary to consider not sailing vessels and yachts.
R and S. 7. The scheme of installation of front struts with sailing performance.
The upper point of the rack should not be lower than the total center of gravity equipped model. For stopping (“catching”) model at the end of the race track is stretched a volleyball net, or several nets, ping-pong table.
For example, we give three possible designs sports avtopromsnab. Now in the solution of individual nodes, we are not going to go, as it will come by itself with time. At this stage, the overall circuit is much more important quest. However, this does not mean that the proposed models have only the nature of the project — two of them actually exist, and work over them, allowed to reveal a number of very specific land “yacht” problems. They mainly relate to the stability of the models against the side of the demolition on the course, as well as balancing and tuning before the race depending on the strength and poristosti wind. An interesting feature of the new technology that emerged during test runs, became napravlennosti upper area — even when functioning machine retention rate because of the variability of the vector of apparent wind model is the race distance on a specific curve.
But in General, a list of design issues that arise when designing and debugging of avtopromsnab, is very large. Gradually we will solve them, constantly introducing readers avtomodelistov with a new direction of technical activities. Now I just want to wish success to those who will interest and engage the subject land vetrogonov.
