FIELD: process engineering.SUBSTANCE: in production of turbo machine straightener with rim provided with several stator blades, first plies of reinforcing part are wound. Mandrel that doubles as the die and has extending parts while said plies of reinforcing parts have long cutouts located opposite said extending parts. Prefabricated plate is placed on every extending part to wind the last reinforcing part plies thereon for form the mid workpiece. Resin is injected into closed die with said mid workpiece to polymerise the latter impregnated with resin. Then, polymerised workpiece is withdrawn from said die to weld the blade root base or flange to every plate. Another invention of the set relates to turbo machine straightener fabricated as described above.EFFECT: higher strength.15 cl, 5 dwg |
