Claim Text:
1. A megawatt-class continuous-flow power installation configured to produce electrical power from a fluid flow, comprising: a base including an azimuth bearing, a supporting ring structure mounted on the azimuth bearing, and an accommodation shell secured on the supporting ring structure; a rotor driven by the fluid flow: and a nacelle supported rotatably on the base and including a drive train operably connected to the rotor, the drive train including at least two functional components supported on the supporting ring structure and configured to convert energy introduced at the rotor by the fluid flow to electrical energy, wherein the accommodation shell is configured to support at least a static weight of the at least two functional components, wherein the at least two functional components comprise (i) a bearing having a bearing housing, the bearing being configured to rotatably support the rotor or a rotor shaft fixedly connected to the rotor, and (ii) a transmission encased in a transmission housing, wherein the bearing housing and the transmission housing are secured to the accommodation shell and to each other by attachment means, the attachment means being configured to withstand dynamic loads on the bearing housing and the transmission under normal operating conditions, wherein the at least two functional components further comprise a generator having a generator housing attached to the transmission housing and to the accommodation shell by the attachment means, the attachment means being configured to withstand dynamic loads which occur on the generator housing under normal operating conditions and to transmit the dynamic loads from the generator housing to the transmission housing and to the accommodation shell, and wherein the accommodation shell has an arcuate shape that is complementary to at least a portion of the generator housing.
