IN SEARCH OF PROFILE

IN SEARCH OF A PROFILEThe rocket plane with Delta wing design is widely known, repeated in dozens of models. However, leading athletes of the country are constantly experimenting, looking for even the long-familiar schemes something new to achieve better results.

Further development of raketoplana wing”, rogallo” was the model athlete from Kazakhstan M. Abrama. For the first time in the practice of rocket modeling it used a wing with S-shaped profile obtained due to deviation up the tail of the skin.
 
The Central beam (the fuselage of the model) is a pine rail section 4X4 mm. In its nasal part of the thread and glue is attached a spring hinge, curved-steel wire Ø 1 mm and in the tail (at a distance of 170 mm from the plastic ski) the top is a bamboo rake secheniem 3×2 mm, which creates a limb of the sail.
Pine side rails, a cross section of 2×2 mm at the end and 4X4 — building. Each is reinforced with carbon fiber on the epoxy binder.
 
Rail-rocker with a length of 430 mm is hinged to the Central beam bottom at a distance of 360 mm from the nose of the rocket. On the free end of the rack fixed fake fairing. It is mounted inside the simplest machine forced landing. When it is activated, the rack and the balancer is deflected forward, translates the model into a dive.
 
Rocket plane with a wing S profile
 
The rocket plane with a wing S profile:
 
1 — stabilizer (balsa), 2 — guide ring, 3 — the body of the carrier (glass). 4 — container system of the descent of the carrier, 5 — fairing (Linden), 6 — Central beam (pine), 7 — side beam (pine), 8 — tail rake (bamboo). 9 — tail wad (polyethylene), 10 — thread-lock, 11 — rack-balancer (pine), 12 — rubber thread, 13 — restrictive thread, 14 — spring hinge (OVS wire Ø 1 mm), 15 — lever-lock of a container (glass fiber), 16 — strand, 17 — limiter (Linden). 18 — the lever of determinator (OVS wire Ø 1 mm), 19 — the fuse.

 
The casing of the flexible wing (the sail) -Mylar film with thickness of 0.03 mm. the vertex angle of the workpiece 98. To the frame of the sail is attached by glue BF-2. The mass of the rocket is 30 g.
 
The body of the carrier is molded from three layers of fiberglass with a thickness of 0,07 mm. Binder — epoxy adhesive. In the forward part of the housing pivotally mounted container stacking system recovery media. In the starting п0ложении the container is pressed against the carrier by a lock — lever mounted on the head fairing. Stabilizers — balsa, from plate thickness of 2 mm. Model is armed with engine MRD 20-10-4.
