Изобретение относиге  кобпасти газотурбостроени . Известна двухъ русна -рабоча  попатка турбомашины, содержаща  наружный и внут ренний профили с разаепитепькой попкой в виде nnacTHHbiLlJ.. Однако такое выпопнени характеризуетс  относительно мапой надежностью при расположении профилей под углом один к другому. Известна также двухъ русна  рабоча  попатка турбомашины, содержаща  наружный и внутренний профипи с раздепитепьной попкой, образованной двум  ппастинами, со диненными рациапьными ребрами 21. Цепью изобретени   вп етс  повышение надежности попагки при расположении профнпей под углом один к другому путем выравнивани  напр жений в попке. Это достигаетс  тем, что ребра расположены под углами, равными углам установки профилей. На фиг. 1 изображена двухъ русна  раб ча  лопатка турбомашины, на фиг. 2 дано сечение А-А на фиг. lina фиг. 3 дано сечение Б-Б на фиг. 1. Рабоча  попатка содержит наружный 1 и внутренний 2 профипи с раздепитепьной полкой 3, образованной двум  пластинами 4 и 5, соединенными радиальными ребрамн 6 и 7, расположенными под угпами равнымц углам установки профилей 1 и 2. Устройство работает следующим образам. 11емтробежна  сипа от наружного профнпй 1 передаетс  через пластину 4, радиальные. ребра 6 и 7jnnacTHHy 5 на внутренний профиль The invention is related to the gas turbine building. The two-sided work of the turbomachine is known, containing external and internal profiles with a razepitepitskoy in the form of nnacTHHbiLlJ .. However, this situation is characterized by relatively reliable reliability when the profiles are angled to one another. There is also a known two-sided working turbomachine containing an outer and an inner profile with a split ass formed by two pastains with a dinosaur ribs 21. The circuit of the invention enhances the reliability of the stripping when the cores are positioned at an angle to one another by leveling the stresses in the ass. This is achieved by the fact that the fins are located at angles equal to the angles of the profiles. FIG. 1 shows a two-sided slave turbomachine blade; FIG. 2 shows section A-A in FIG. lina FIG. 3 shows the section BB in FIG. 1. The working foil contains outer 1 and inner 2 profi with a separating shelf 3 formed by two plates 4 and 5 connected by radial ribs 6 and 7, located under angles equal to the installation angles of profiles 1 and 2. The device works as follows. 11th the rattle vortex from the outer profile 1 is transmitted through the plate 4, radial. ribs 6 and 7jnnacTHHy 5 on the inner profile 2. Расположение ребер 6 и 7 йод угпами, равными углам установки профилей 1 и 2 соответственно, обеспечивает равно мерное распределение напр жений в ребрах ив пластинах. Выравнивание напр жений сопровопождаетс  уменьшением коэффициентов концентрации напр жений в полке и njmBooHtr к повышению надежности лопатки. Формула изобретени  Двухъ русна  рабоча  лопатка турбома- шины, содержаща  наружный и внутренний профили с разделительной полкой, образованной двум  пластинами, соединенными ра2. The location of the ribs 6 and 7 of iodine, equal to the angles of installation of profiles 1 and 2, respectively, ensures an even distribution of stresses in the edges of the plates. Equalization of stresses is accompanied by a decrease in the stress concentration ratios in the shelf and njmBooHtr to increase the reliability of the blade.
