| 主权项 | 1. A blade outer air seal assembly of a turbomachine, comprising: a blade outer air seal that is biased toward a second part, wherein the blade outer air seal and the second part move together radially during operation, and the second part rotates relative to the blade outer air seal during operation of the turbomachine, wherein radial inward movement of the blade outer air seal is limited exclusively by the second part during operation, wherein the blade outer air seal is biased radially inward with a pressurized fluid; and a supporting structure comprising at least one circumferential seal, wherein the blade outer air seal is supported exclusively during operation with the at least one circumferential seal, or is supported exclusively during operation with the at least one circumferential seal together with at least one circumferentially adjacent blade outer air seal, the second part, or both. | ||
