уменьшаютс  потери в решетках последующих ступеней за счет обтекани  лопаток более равномерным потоком. Формула изобретени  Многоступенчатый компрессор, осевой или осерадиальный, содержащ,ий группу ступеней с кратным числом лопаток в одноименных решетках , смеш.енных одна относительно другой в окружном направлении, отличаюш ,ийс  тем, что, с целью повышени  экономичности , смещение определено соотношением То±а-, з Vn где фо - -относительное смещение между плоскост ми, проход щими через вершины входных кромок лопаток одноименных решеток и ось компрессора; .. {(.,cos,,) + ,i+ stg a3 равный 0,06а - коэффициент, Гь Г2 - средние радиусы лопасток разноименных решеток; , 3 - средний радиус и шаг одноименной решетки следующей по ходу рабочего тела ступени; i, ay-шаг, хорда и угол установки лопаток; ь б2 - осевые зазоры между разноименными решетками соседних ступеней; В - ширина разноименной решетки , следующей по ходу рабочего тела; 2, р1 - конструктивные углы выхода и входа потока на среднем радиусе лопаток одноименных решеток соседних ступеней; k - целое число, удовлетвор ющее соотношению of, --- .losses in the lattices of subsequent steps are reduced due to a more uniform flow around the blades. Claims of the invention. A multi-stage compressor, axial or axial radial, contains a group of stages with a multiple of blades in the same grids mixed one relative to another in the circumferential direction, distinguished by the fact that, in order to increase efficiency, the displacement is determined by the ratio To ± a -, s Vn where fo - is the relative displacement between the planes passing through the vertices of the input edges of the blades of the like grids and the axis of the compressor; .. {(., cos ,,) +, i + stg a3 equal to 0.06a - coefficient, Гь Г2 - average radii of the vanes of opposite lattices; , 3 - the average radius and pitch of the lattice of the same name following the step along the working medium; i, ay-pitch, chord and angle of the blades; l b2 - axial gaps between opposite lattices of adjacent steps; In - the width of the opposite grid, following along the working fluid; 2, p1 - structural angles of exit and entry of the flow on the average radius of the blades of the same gratings of adjacent steps; k is an integer satisfying the relation of, ---.
