用于在翼修理的燃气涡轮机原位可充胀囊
摘要：
本发明提供用于修理燃气涡轮发动机内的部件的表面的方法。第一囊和第二囊可以(同时地或独立地)安装在燃气涡轮发动机内。第一囊和第二囊然后可以用充胀流体充胀以形成第一周向密封和第二周向密封，从而在燃气涡轮发动机内限定隔离区域。然后可以用掩蔽层涂覆隔离区域内的所有表面。然后可以去除掩蔽层的至少一部分以暴露工作区域，并且可以在工作区域上形成涂层。
摘要（英）：

Methods are provided for repairing a surface of a component 204 within a gas turbine engine 10. A first bladder 100 and a second bladder 200 can be installed (simultaneously or independently) within the gas turbine engine 10. The first bladder 100 and the second bladder 200 can then be inflated with an inflating fluid to form a first circumferential seal and a second circumferential seal to define an isolated area within the gas turbine engine 10. All the surfaces within the isolated area can then be coated with a masking layer 306. At least a portion of the masking layer 306 can then be removed to expose a working area, and a coating can be formed on the working area.
