Mount the valves to the tail block on the hinges from strips of nylon with a width of 6 mm. First, glue the inner leaf. On the outer surface of the fixed gum for their disclosure. One end of the elastic to the point of strengthening the tail unit, the other to the sash at a distance of 40 mm from the bottom edge.
To limit the angle of opening of the valves (75° from the vertical axis of the model) on the inner side of the blade is fixed to the thread-limiter made of Kevlar. Its other end is attached to the upper edge of the caudal block. It is the glue and thread suspension brake belt length 800 mm. in the same way and hung external doors. They do not have elastic opening and are deflected by the interior, but the thread-limiter attached to them.
And yet, external doors are fitted circumferentially offset by 45° relative to the inner so that their joints do not mix – due to possible occurrence of turbulence and destruction of missiles in flight.
Mandrel for production of a model class Ѕ6А:
a – fairing; – tail block
In the expanded form model, its body, similar to a funnel or cone with an internal angle of 150°. To increase the area of braking by a larger opening angle of the valves should not be. This taper provides a stable position of the model during the descent.
The model is equipped with a brake tape dimensions 150×1550 mm, film thickness of 0.03 mm.
Preparing the rocket for launch produce in such sequence. Connect the thread of the fairing with the tail section and tied it to the brake band. In the tail section of MRD is inserted, locking it with a latch from accidental shooting, and close the top with a wad of foam. Then fold the inner fold, forming a cylinder, the free end of which wear (10 mm) fairing, or rather its retaining ring, after having put inside the brake band. Then fold in the cylinder outer folds, pressing them to the inside, and to stop wear on the top fairing, which captures them from disclosure. The model is ready to start.
In flight, at an altitude of 180 – 190 m works lifting charge MRD, which “shoots” fairing, releasing the sash of the case. They’re under the effects of the gum are disclosed, forming a kind of funnel. At the same time reveals brake band and model lands.
