    • A gas turbine engine having a longitudinal centerline axis therethrough, including: a fan section at a forward end of the gas turbine engine including at least a first fan blade row connected to a first drive shaft; a booster compressor positioned downstream of the fan section, the booster compressor including a first compressor blade row and a second compressor blade row connected to a second drive shaft and interdigitated with the first compressor blade row; and, a pulse detonation system for powering the first and second drive shafts. The pulse detonation system powers only the second drive shaft during a first designated condition of the gas turbine engine and both the first drive shaft and the second drive shaft during a second designated condition of the gas turbine engine. The first and second drive shafts are powered independently of each other by the pulse detonation system.
    • 一种燃气涡轮发动机,其具有穿过其的纵向中心线轴线,包括:在所述燃气涡轮发动机的前端处的风扇部分,至少包括连接到第一驱动轴的第一风扇叶片排; 位于所述风扇部分下游的增压压缩机,所述增压压缩机包括连接到第二驱动轴并与所述第一压缩机叶片排交叉的第一压缩机叶片排和第二压缩机叶片排; 以及用于为第一和第二驱动轴供电的脉冲爆震系统。 在燃气涡轮发动机的第一指定状态期间,在燃气涡轮发动机的第二指定状态期间,脉冲爆震系统仅为第二驱动轴供电,而在第一驱动轴和第二驱动轴两者之间。 第一和第二驱动轴通过脉冲爆震系统彼此独立地供电。

    • A method is provided for interconnecting an end of a pipe with a hollow structure having a screw-threaded tubular inlet thereto. The method includes applying a one-part annular sealing member around the pipe, wherein the annular sealing member has a screw-threaded portion for engagement with the screw-threaded tubular inlet and is provided with the first and second sealing means; distorting outwardly the end of the pipe around at least a portion of the periphery thereof; and effecting screw-threaded engagement between the annular sealing member and the tubular inlet, such that sealing engagement is effected between the annular sealing member and the pipe end over a plurality of relative axial positions therebetween. The first sealing means effects sealing engagement between the annular sealing member and the inlet, and the second sealing means effects sealing engagement between the annular sealing member and the pipe end. Axial movement of the pipe relative to the annular sealing member is permitted when the annular sealing member is in sealing engagement with the pipe end.
    • 提供了一种用于将管的端部与具有螺纹管状入口的中空结构互连的方法。 该方法包括在管子周围施加一部分环形密封件,其中环形密封件具有用于与螺纹管状入口接合的螺纹部分,并且设有第一和第二密封装置; 向外扭曲管周围的至少一部分的端部; 并且在环形密封构件和管状入口之间实现螺纹接合,使得在环形密封构件和管端之间在多个相对轴向位置之间进行密封接合。 第一密封装置实现环形密封构件和入口之间的密封接合,并且第二密封装置实现环形密封构件和管端之间的密封接合。 当环形密封构件与管端密封接合时,允许管相对于环形密封构件的轴向运动。
