The design of the “Slavutich-UT” is a classic: tubular frame, cable system stretching and edging with the main elements of armor. The device is equipped with removable wheels and safety antieconomy device. The kit also includes a suspension system.
The frame is tubular, the main elements are connected together pivotally in the nasal, Central and lateral nodes.
The diameter of the pipes leading edges and keel — 42X1 mm, cross — 42X1,5 mm. they are All made of duralumin D-16T, each has technological and operational connectors. In pipes forming a front edge, two of them; in these places there are bougie. The middle part of the front edge side in the area of site meter reinforced bougie.
The keel has technological and operational connectors. The first is to strengthen the Central node.
Cross pipe consists of two parts, symmetrical relative to the Central node, each has an operational connector.
The location and number of ports were selected based on the conditions of ensuring the strength, resource, and minimum weight when size of the glider in the package is not more than 2,200 mm In the open ends of the pipes inserted plastic core, and the connections with the nodes are the same plastic curved puck.
The side and keel of the pipe is pivotally connected to the forward node, which represents the spinner and consists of a U-shaped steel plate with a channel and an earring.
The Central node consists of two channels. In the upper part is attached to the mast support cables; installs in the lower steering linkage.
Side node frame fork construction: nodes of fastening of cross bar and side cables apart, which allowed to exclude the impact of the pipe joint in a side knot on the aerodynamics of the wing.
Steering linkage consists of two side plates and a handle connected by a hinge. The sides have the technological plugs in case replacing the straight sections when they break.
Tether systemthat holds the frame of the hang glider, consists of top and bottom steel cables d 2.5 mm, clamped through shackles in earrings, clips and carabiner. The upper brace connects the nasal and the lateral nodes, and a node on the keel through the top of the mast. Cables near the top have the limiters moved. Between the nose knot and rope, and between the left side and a cable, installed the toothed adjusting elements of the longitudinal and transverse tensioning cables.
The lower cables are attached to the bracket on the trapeze and do not have the adjusting elements. The carbine front of them are increased requirements for durability and quality workmanship.
All cables have the machine sealing of the ends of the sleeve by compression and coated with a vinyl chloride sheath.
For mounting in main nodes of the glider uses M8 bolts, the auxiliary — less M6. Permanent connections are made using self-locking nuts, split — locking pins.
Antiekeradio device of the glider comprises three main elements. Chief among them is the keel profiled Lata established between the Central and nasal node. It provides the constancy of the shape of the nose of the wing in Kileva section.
Root hard armor plating, the ends of which are connected by ropes to the mast, give the profile a reverse curvature in the cross section of the wing at low angles of attack. And the last element contributing to the stability of the device — end support for the sheathing, limiting the decrease in the twist end of the wing at low angles of attack.
To ensure safety in the event of rough landings while training glider equipped with quick-release wheels that are installed on the handle of a trapezoid.
Suspension system formed quilted cradle, belts, rope, snap hook and stirrup. It helps to easily make the takeoff and landing, but the main thing — to perform a long flight: in flight the athlete lies like a cradle.
The covering of the glider consists of a fabric “sails”, the side and keel pockets. Shaping the surface of the wing in flight, the aerodynamic load on the bearing surface, deformation of the framework — the whole complex of factors inherent in the sail cut on the leading edge, ciliau section and in the section “oblique” armor. Material is a Dacron fabric sailing “Boat-Up”.
To ensure the formation of the wing in the casing at a joint of panels completed laderman in which to insert armor. Eight of them focused on a stream of four — “skew”. Themselves armor — tubular, d 16X1,5 mm, of high density polyethylene. The bow of those that are oriented to the flow has a constant magnitude radius of 400 mm and a straight tail section.
Due to the fact that the volume of articles makes it impossible to publish the drawings with detailing, production and technological instructions, apparatus made according to the information presented here, should be subjected to examination in technical committees of the Federations and clubs DOSAAF according to the current technical requirements of a self-made hang gliders.
