    摘要： The present embodiments relate to a pitch angle blocking device 200 for blocking the pitch angle of a multi-blade rotor 110 that has neighboring first and second rotor blades 112 in circumferential direction 205 that extend from a rotor hub 113 of a rotary-wing aircraft 100 in non-operational mode of the rotary-wing aircraft 100. The present embodiments further relate to a multi-blade rotor 110 of a rotary-wing aircraft 100 that is adapted to receiving such a pitch angle blocking device 200, and to a rotary-wing aircraft 100 with such a multi-blade rotor 110. The pitch angle blocking device 200 comprises first and second attachment means 210 that are configured to be non-rotatably and releasably attached to the first and second rotor blades 112 spaced apart from the rotor hub 113, and a connecting device 230 that non-rotatably connects the first attachment means 210 with the second attachment means 210.

    摘要： Accordingly, it is an object of this invention to provide a fluid compressor comprising: a rotatable turbine mounted to a mast; a toroidal intersecting vane compressor (TIVC) characterized by a fluid intake opening and a fluid exhaust opening, wherein the rotation of the turbine drives the compressor. The combination of the TIVC and turbine permits good to excellent control over the hours of electrical power generation, thereby maximizing the commercial opportunity and meeting the public need during hours of high usage. Additionally, the invention avoids the need to place an electrical generator off-shore. Further, the apparatuses of the invention can be operated with good to excellent efficiency rates.
