    摘要: A heat transfer body 3 is prepared. The heat transfer body 3 forms an inner space 7 for existence of one of a higher-temperature fluid or a lower-temperature fluid. The heat transfer body 3 constitutes a heat exchanger, and is formed of a copper material as a wall surrounding the inner space 7. In the wall, a flow path through which the other of the higher-temperature fluid and the lower-temperature fluid flows is formed. By LMD treatment, an LMD layer is formed directly on an outer circumferential surface 3a of the heat transfer body 3. In the LMD treatment, a metal material is supplied to a supply position on the outer circumferential surface 3a, and the supply position is irradiated with laser light to form an LMD layer 5. An energy density of the laser light is set to melt both the metal material and the outer circumferential surface 3a.

    摘要: A docking device including: a base ring 2 disposed in a first space vehicle A; a first-side capturing ring 3 for coming into contact with the second space vehicle B; six links 4 that constitute a parallel link mechanism 5 for coupling the base ring 2 to the first-side capturing ring 3; and linear actuators 10, each of which extends and contracts the link 4 by using a motor 13 as a driving source, wherein resistance generation mechanisms, each of which generates a regenerative current in the motor 13 of the linear actuator 10 to produce resistance force when the second space vehicle B comes into contact with the first-side capturing ring 3 and the link 4 receives a compressive load, are provided. Correction of misalignment with the second space vehicle, and attenuation of inertia force that the second space vehicle has can be performed without requiring complicated electrical control, and simplification and cost reduction of an electrical system can be implemented.

    摘要: A coupling support member 33 including a pair of divided pieces 34, 34 is placed in a coupling part between a vane proximal end portion 21 of a guide vane 20 and an attachment flange 31f, and the pair of divided pieces 34, 34 are joined to the vane proximal end portion 21 from both the sides in the vane thickness direction. A groove 35b is formed in one end portion joint surface 35a of the coupling support member 33, a linear protrusion 35c is formed on the other end portion joint surface 35a, the vane proximal end portion 21 is formed into a concavo-convex shape, a linear protrusion 21b that is engaged with the groove 35b which is formed in the end portion joint surface 35a is formed on a joint surface 21a to the one end portion joint surface 35a, a groove 21c that is engaged with the linear protrusion 35c formed on the end portion joint surface 35a is formed in the joint surface 21a to the other end portion joint surface 35a. The vane proximal end portion 21 is held between the pair of divided pieces 34, 34 of the coupling support member 33, by the fastening force that is applied to the coupling support member 33 from both the sides in the vane thickness direction. It is possible to obtain a high structural strength while contributing to a reduction in weight of a jet engine.

    摘要: A cylindrical case includes: a case main body 10 made of a composite material of reinforcing fibers impregnated with a thermosetting resin; and a groove 12 disposed annularly at one end of the case main body 10. A peripheral wall 10a of the case main body 10 is formed by alternately laminating a biaxial fabric layer 13, which includes a biaxial fabric 13A of a non-crimp structure composed of reinforcing fiber bands 13a, 13b having an orientation angle of ±45°, and a roving layer 14, which includes a roving 14A composed of a bundle of reinforcing fibers extending along the circumferential direction. A groove wall 12a of the groove 12 is formed by alternately laminating the biaxial fabric layer 13, which continues to the case main body 10 side, and a triaxial fabric layer 15, which includes a triaxial fabric 15A of a non-crimp structure composed of reinforcing fiber bands 15a, 15b having an orientation angle of ±45° and a reinforcing fiber band 15c having an orientation angle of 0°. It is possible to secure high torsion strength and torsion rigidity of the entire cylindrical case, in a case where the cylindrical case is a fan case which is made of a composite material consisting of reinforcing fibers and a thermosetting resin as the raw material and has an annular groove.

    摘要: Multipliers 21a and 21b output values, which are obtained by multiplying a total drive command value E s by first and second gains G 1 and G 2 , respectively, as first and second drive command values E 1 and E 2 . Controllers 23a and 23b control first and second actuators (motors) 5 and 7, respectively, on the basis of the first and second drive command values. The detection values of the drive amounts of the actuators are denoted by E f1 and E f2 , respectively, and the detection value of the drive amount of a driven body is denoted by E f . A gain calculator 27 calculates the gains G 1 and G 2 on the basis of E f1 , E f and E f2 . An upper limit value of E f , which denotes the drive amount of the driven body, is denoted by L max . When E f1 , E f2 or E f approaches zero, the first gain G 1 is brought close to (E f1 - L max /2)/(E f - L max ).
