    摘要： A gas turbine combustor is provided which can accomplish stable high-load combustion, high combustion efficiency, a low concentration of CO, and NOx in a small-sized combustion chamber. The gas turbine combustor includes an inner liner 12 and an outer liner 14 being concentric and cylindrical and an end liner 16 closing between upstream ends thereof and forms a hollow cylindrical combustion chamber 18 therein. The gas turbine combustor further includes a swirling air flow forming device 22 introducing combustion air 7a into the vicinity of the end liner in the combustion chamber 18 from the outside and forming a swirling air flow, a fuel ejector 24 ejecting fuel 8 in the swirling direction to form a premixed swirling flow, and an igniter 26 igniting the premixed swirling flow to form a tubular flame surface 11. The combustion chamber 18 includes a primary combustion chamber 18a disposed close to the end liner, a secondary combustion chamber 18b disposed downstream of the primary combustion chamber, and an annular restrictor 19 reducing the outer diameter of the primary combustion chamber and being disposed therebetween. A diluting air hole 30 supplying diluting air along a flow of the combustion gas passing through the restrictor is disposed downstream of the restrictor 19 in the inner liner 12.

    摘要： In an oil pressure generating device (200) of a crosshead engine, the plunger tail is located on the outer part of the main member, and the plunger head faces a pressure-boost chamber (216) inside the main member (202). The oil pressure generating device (200) has: plungers (210a, 210b) that slide in a direction intersecting the stroke direction of a piston; first pressing parts (236, 240) that are disposed apart from the main member in the sliding direction of the plungers, wherein the distance of separation from the main member is a first distance (La), and the pushing amount of the plungers into the pressure-boost chamber side is a first pushing amount; and second pressing parts (238), wherein the distance of separation from the main member is a second distance (Lb), and the pushing amount of the plungers into the pressure-boost chamber side is a second pushing amount that is greater than the first pushing amount. The oil pressure generating device (200) is provided with plunger pressing members (204a, 204b) that push the plungers to the pressure-boost chamber side while the plungers move from the first pressing parts to the second pressing parts.

    摘要： A vertical take-off and landing aircraft includes a propulsion mechanism 2 that generates lift and thrust, a main frame 4 that supports seating 41 and a landing undercarriage 42, a sub-frame 5 which supports the propulsion mechanism 2 and is arranged so as to be swingable back and forth relative to the main frame 4, a motive power supply unit 3 supported by the main frame 4 and supplying motive power to the propulsion mechanism 2, a control stick 6 connected to the sub-frame 5, and a main wing 7 arranged on the propulsion mechanism 2, wherein the main wing 7 is formed to be retracted to a position not interfering with an air flow of the propulsion mechanism 2 in a normal time and to be movable to a position where lift is generated when thrust is lost. Gliding is made possible even if thrust is lost while increasing in size of a fuselage is avoided.
