    • PROBLEM TO BE SOLVED: To provide a steering control method and device of a steering wing that can fully utilize a region for obtaining improved steering, can avoid a region where the steering becomes inferior, prevents controllability from deteriorating, and further can miniaturize a steering device. SOLUTION: A steering control method consists of an effective steering detection process for obtaining the maximum effective steering angle δemax for achieving effective steering for a speed Vm and an elevation α of a flying object that is subjected to flying control, a steering distribution process for distributing the maximum effective steering into the maximum pitch steering δzmax and the maximum steering δxmax corresponding to the speed and elevation, respectively, by assuming the speed and elevation of the flying object, and a steering process for controlling flying by a steering operation based on an inputted steering instruction with a steering being obtained by synthesizing the maximum pitch steering and the maximum roll steering as the maximum value.

    • PROBLEM TO BE SOLVED: To reduce air resistance upon straight flying by providing a shape memory alloy so as to partly cover a head surface of a flying structure, the shape memory alloy being changed so as to protrude to the outside of the flying structure with a temperature change and performing the same action as a steering wing. SOLUTION: A computer 8 calculates the amount of displacement of a shape memory alloy 6 based upon an induction signal outputted from an induction apparatus 4, an acceleration signal and an angular velocity outputted from an attitude detector 5, and outputs it to a temperature controller 11. The temperature controller 11 turns on a heater power supply 10 to change the shape memory alloy 6 such that it is protruded to the outside of the flying structure 1, and controls the heater power supply 10 to adjust the temperature of the heater 9 such that the amount of displacement from the computer 8 and the amount of displacement from a distortion gauge 7 are coincident with each other. Once the shape memory alloy 6 is changed so as to protrude to the outside of the flying structure 1, flying force is produced on the side to which the shape memory alloy 6 is changed, and hence the attitude of the flying structure 1 is changed to alter a flying path.

    • PURPOSE:To enable a posture control of a missile to be performed by a method wherein a plurality of projections are arranged at a circumferential part of an injection nozzle for combustion gas for use in promoting the missile in such a way as they be advanced or retracted and the projections are advanced or retracted into the injection nozzle by each of the actuators. CONSTITUTION:Combustion gas in a rocket motor 1 is expanded and increased in its speed within an injection nozzle 2. Under a condition in which a plurality of projection plates 3 are not projected, an interface layer 10 similar to a normal fixed type nozzle is produced, and an axial thrust force is generated. As one of a pair of projections 3 is projected into the injection nozzle by an actuator 41 the interface layer 10 is developed at a downstream side of the projected projection 3, the interface layer 10 and a speed distribution are varied and a direction of a thrust force 11 is varied to such a direction as one to be displaced toward the opposite side of the projected projection 3. In this way, it is possible to perform a posture control of the missile without depending upon its speed in respect to air.
