Abstract
1. Сборная турбинная лопатка (10), содержащая первую секцию (18), вторую секцию (100) и третью секцию (160), причем первая секция обеспечивает конструктивную опору для остальных секций, вторая секция присоединена с образованием единого целого к первой секции, а третья секция соединяет первую и вторую секции.2. Лопатка (10) по п.1, в которой первая секция (18) содержит имеющий аэродинамическую форму несущий нагрузку элемент (24, 26) и имеет первый конец (20) и второй конец (22).3. Лопатка (10) по п.2, в которой указанный первый конец (20) выполнен как единое целое с ротором или прикреплен к нему.4. Лопатка (10) по п.2, в которой вторая секция (100) защищает второй конец (22) от воздействия повышенных температур, высокоскоростных потоков газа или иной опасной окружающей среды.5. Лопатка (10) по п.1, в которой третья секция (160) содержит втулку.6. Лопатка (10) по п.1, в которой третья секция (160) прикреплена ко второй секции (100) с помощью припоя.7. Лопатка (10) по п.2, в которой третья секция (160) прикреплена ко второму концу (22) первой секции (18) с помощью любого подходящего способа, обеспечивающего в результате соединение, имеющее высокую механическую целостность.8. Сборная турбинная лопатка (10), содержащая первую секцию (18), вторую секцию (100) и третью секцию (160), причем первая секция обеспечивает конструктивную опору для остальных секций, содержит несущий нагрузку элемент (24, 26) и имеет первый конец (20), выполненный как единое целое с ротором или прикрепленный к нему, и второй конец (22), подвергающийся воздействию повышенных температур, высокоскоростных потоков газа или иной опасной окружающей среды, причем вторая секция (100) защищает второй конец от опасной среды, а третья с�1. A prefabricated turbine blade (10), containing the first section (18), the second section (100) and the third section (160), the first section providing structural support for the remaining sections, the second section is attached to form a single whole to the first section, and the third section connects the first and second sections. 2. A blade (10) according to claim 1, wherein the first section (18) comprises an aerodynamically shaped load bearing element (24, 26) and has a first end (20) and a second end (22). A blade (10) according to claim 2, wherein said first end (20) is integral with or attached to the rotor. A blade (10) according to claim 2, in which the second section (100) protects the second end (22) from the effects of elevated temperatures, high-speed gas flows or other hazardous environment.
