    摘要: A gas turbine engine (20) includes a spool (30), a turbine (46) coupled to drive the spool (30), a propulsor (42) coupled to be rotated about an axis by the turbine (46) through the spool (30), and a gear assembly (48) coupled between the propulsor (74) and the spool (30) such that rotation of the turbine (46) drives the propulsor (42) at a different speed than the spool (30). The propulsor (42) includes a hub (76) and a row of propulsor blades (74) that extend from the hub (76). Each of the propulsor blades (74) has a span between a root (68) at the hub (76) and a tip (80), and a chord (30) between a leading edge (82) and a trailing edge (84). The chord forms a stagger angle α with the axis (A), and the stagger angle α is less than 15° at a position along the propulsor blade (74) that is within an inboard 20% of the span.

    摘要: A turbine generator comprising a turbine rotor comprising a hub and one or more blade stages. Each stage comprising a circumferential array of rotor blades in driving engagement with the hub. A turbine stator comprising a hub and one or more vane stages, each stage comprising a circumferential array of vanes. The turbine rotor and turbine stator being concentrically arranged about a common axis to define an annular flow path. The vane stages and blade stages being axially spaced along the axis and having one or more magnets arranged on the rotor. A generator stator concentrically aligned with the turbine rotor and turbine stator and one or more magnets arranged on the rotor. In use, when the turbine is driven to rotate about the axis, the or each of the magnets on the turbine rotor rotate relative to the generator stator in order to generate electric power.

    摘要: According to an exemplary embodiment of the present invention, since the pressure space of the cylinder is bisected into a vacuum state and a pneumatic state to alternately form a pressure difference, it is possible to generate the kinetic energy of the piston and convert the kinetic energy into other necessary energy. To this end, an exemplary embodiment of the present invention provides an energy conversion apparatus including an energy conversion module including a piston, a piston rod provided on one side of the center of the piston, a cylinder divided into a first pressure space and a second pressure space to be relatively varied with the piston interposed therebetween, and an external air opening/closing part selectively opening and closing the external air to the first pressure space and the second pressure space, respectively; a first bellows containing a fluid therein and provided in the first pressure space to be compressed and expanded; a second bellows containing a fluid therein and provided in the second pressure space to be compressed and expanded; a fluid movement pipe which is positioned outside the cylinder and connects the first bellows and the second bellows to each other to form a closed space, and through which the fluid accommodated therein moves by pressure; a first bellows pressing part for pressing one side of the first bellows; second bellows pressing part for pressing one side of the second bellows; a first motor transmitting a driving force to the first bellows pressing part; and a second motor transmitting a driving force to the second bellows pressing part.
