摘要： PROBLEM TO BE SOLVED: To provide a method for producing a composite member with reduced wrinkles.
SOLUTION: The method for producing the composite member includes a step of shaping a laminate [4], in which prepreg sheets are laminated, along a mold [7]. The laminate [4] includes a first layer wherein fibers are arranged in one direction. In the first layer, a first surface [44a] intersecting the one direction and a second surface [44b] intersecting the one direction are arranged to face each other.

摘要： PURPOSE: To detect the direction of air flow without rotating a conical body fixed to the outer surface of an airplane by setting a specific number of pressure detection holes in the circumferential direction of the surface of the conical body. CONSTITUTION: Two conical bodies 4 are fixed horizontally in a direction generally at a right angle to the direction of the axis of an airplane at the right and left outer surfaces of a nose 10 of the airplane. Three pressure detection holes 1 to 3 are formed via a distance of 30 deg. in the circumferential direction on the surface of each conical body 4, which are connected to a pressure sensor. In general, the pressure distribution of air flow around a conical body can be approximated by the potential flow theory. The pressure value of the detection hole 1 to 3 can be adjusted by a direction αof the air flow regardless of the speed of the air flow, that is, an angle defined by the air flow and an axial direction of the hole 1, and a differential pressure of the detection holes and the direction α hold a constant relationship. Accordingly, the direction αcan be continuously detected by detecting pressures of pressure holes 1 to 3 and differential pressures of detection holes 1 and 2, and 1 and 3.

摘要： PURPOSE:To provide a lift variable device which solves a trouble such that airframe strength must be designed in a speed area where respective lift bearing ratios of the main wing, tail plane and body bearing the lift of an aircraft are maximum because they are fluctuated according to the change of speed, resulting in an excessive strength design, which causes an increase in airframe weight. CONSTITUTION:A lift variable device is formed of a speed sensor 11 for detecting the flying speed of an aircraft; a memory 12 for storing the operating quantity data for operating a lift surface capable of controlling a generated lift so that the lift surface can generate a lift of a substantially fixed ratio of the total airframe lift in all flying speed areas; and a control device 13 for reading the operating quantity data from the memory in conformation to the signal from the speed sensor, and operating the lift surface according to the speed. Since the lift surface is operated to have a substantially fixed lift bearing ratio from subsonic area to supersonic area to fly the aircraft, troubles such as increase in airframe weight, reduction in loading cargo, and increase in resistance which accompany an excessive strength design can be solved.

摘要： PURPOSE:To produce no loss of blank and moreover to cut out the blank easily by a method in which after the equilateral quadrilaterals with constant length of sides have been set closely in order on a curved surface based on reference lines, they are developed in rectangles and are copied on a plane, thereby determining the necessary dimension and shape of the blank. CONSTITUTION:Reference lines A, B are defined on the high dimensional curved surface 11 of a prescribed dimension and shape to be obtained. There reference lines A, B are two lines defined so as to cross at one point C on the curved surface 11. Next, the equilateral guadrilaterals with constant side length are closely set in order on said curved surface 11 based on said reference lines A, B. Here, the equilateral quadrilateral means that the coordinate of a point (d) is obtained from the three points (a), (b), (c) on the prescribed curved surface. Next, the set quadrilaterals are developed in rectangles, they are copied on a plane, thereby determining the necessary dimension and shape of the blank. Then, since it may be calculated and determined by a computer,the decision of the dimension and shape of the blank is easy.
