EXACTLY WHAT

Sailboats of class “P” are popular among modelers of the school. Indeed, these yachts-promocode with all their Aero – and hydrodynamic perfection does not require expensive remote control equipment, moreover, in this class of ship modelers-designers can realize their wildest design dreams.

A rigid sail-wing has long been used in the yacht class “P” as a highly efficient propulsion. Among its advantages primarily include high aerodynamic quality and consistency of its shape, which favorably affects the speed and stability of motion, and hence the course.

 

In the “Modeller-designer” has repeatedly published materials on the Coleoptera sailing. Today we talk about another one design yacht class “P”, which at high speed is able to go the distance with minimal deviations from the desired course.

 

To take up the construction of this model is best for two-Threesome — matrix method of forming the hull is most suitable for manufacturing small series of yachts.

 

The design of the proposed sailboat charm. Thus, the geometry of its body borrowed from the high-speed three-point hydroplane, but the engine of the yacht is a self-oriented with auxiliary sails-the stabilizer system of Diptera, resembling biplane box (if you use aviation terminology).

 

Swivel mount pairs of sail-wings, allowing them to samoustraniajutsia at the optimum angle to the wind in a sufficiently wide range of courses, but when you change the speed of a sailboat or the direction of the wind sails will automatically occupy the desired position. Some disadvantage of this scheme is its “dvuhseriynoy” — when the fresh breeze model is easy glissirovat, but with the weakening of the wind model continues to move in displacement mode at a lower speed.

The hull of a sailboat is fairly simple, so the constructor of ship models can choose any technology of its production. In particular, it is possible to do a stacked body with a shell of mm plywood, you can cut a billet of foam and paste over it with a thin fiberglass using epoxy resin. It also proposed a matrix method, which can be used to replicate the hull, creating a fleet of boats with hulls with monotypes.

 

The first stage is the fabrication of the master model, or, as it is dissonant-called experts, fool. This will suit almost any materials, but the easiest way to do the Central building of the pair of plates of the sidewall thickness of 10-15 mm and a plywood bottom and decks. Side floats — lime bricks.

 

After docking all three elements of the master model puttied carefully skurida and painted with several layers of nitroenamels with intermediate grinding. Ready master model is covered with a release layer (e.g., two or three layers of wax parquet putty with careful polishing).

 

Model sailing ship class “P” with swivel-sail system:

 

1 — the sail-wing; 2 — knot sailing system, articulated; 3 — keel (plywood s5); 4 — housing; 5 — feather of a steering; 6— sail-stabilizer; 7 — M6 screw mounting sails-stabilizer; 8 — nut M5 mounting hinge Assembly; 9 — cross member.

 

The position of the sail-wings b sails-stabilizer in various courses:

 

A — in the course of a close-hauled port-tack; B — on the course before the wind; In — course close-hauled starboard tack.

The next operation — making matrix. First, the lower part of the hull (without deck) glued a couple layers of thin fiberglass using as a binder an epoxy resin. The first layer is carefully pressed against the surface of jerk between him and the fiberglass should not be air bubbles and excess resin.

 

After polymerization of the resin composition is prepared from normal river sand and of the same “epoxy”. The resulting mass is laid in a wooden box, whose dimensions slightly exceed the dimensions of the enclosure, and then up to deck level “dives” the master model with preformula-tion to her shell of fiberglass. Epoxy-sand composition is compacted by carefully tapping on the box and the surface of the mass is aligned flush with the deck level of the hull. The next day the master model carefully extracted from the body — the matrix is ready.

 

Now take up the actual production of housing. The inner surface of the matrix by the already familiar technology is covered with a release layer, whereupon it is applied to the front layer of the future shell case — tinted nitro epoxy resin. Without waiting for complete curing of this layer (the resin should still be sticky), inner surface of the die is glued with fiberglass (3-5 layers depending on tissue thickness), and the first layer of the most thin fabric privorovyvat to the matrix carefully. Carefully fit the fabric into the corners (edges) of the case.

 

After polymerization, the epoxy resin body shell is removed from the die and it cut the holes for rudders and keels. Further, the housing is glued cross of pine boards 20 mm thick, designed for fastening it to the hinge Assembly dvuhyarusnaya system.
