FIELD: transport, production processes.
SUBSTANCE: proposed method comprises stretching metallised knitted reticular sheet with preset force, cutting it into fragments and serging along radial directions to provide for required shape and sizes. The said sheet is cut into wedge-like fragments with the width of allowances not less than that of the form-building structure elements representing band. Then, these fragments are folded so that allowances get overlapped to be serged with zigzag seam over entire width of allowance. Now the reticular sheet working surface is placed on processing appliance representing required-shape 3D template, stretched with preset force to rule out surface irregularities. The required shape and sizes attained, the aforesaid sheet is fixed by means of the band staples relative to the bands surfaces. Note that the bands are preliminary placed on the said template and adjusted with the help of tangential cords to the required shape of the sections located nearby seams. Processing appliance is removed after mounting the reticular sheet on the strength carcass and reference marks are applied onto the said sheet working surface. Reflector working surface is finally adjusted with its aperture upwards and downwards and, then, tested. The working surface results with root-mean-square departure from theoretical profile not exceeding 1.3 mm measured after all tests at, approximately, 2700 points.
EFFECT: high-accuracy profile, guaranteed operation in orbit.
