    Abstract: PROBLEM TO BE SOLVED: To reduce the BVI noise of a helicopter effectively. SOLUTION: For reducing the BVI noise of the rotor blades 2 of the helicopter, a spoiler 3 capable of being reciprocated nearly in the vertical direction between a protruded position and an unprotruded position from the upper face and the lower face of each rotor blade 2 is provided between the front edge and the rear edge of the rotor blade 2. An actuator 4 reciprocating the spoiler 3 is provided for each spoiler 3 on a rotor system 1 including the rotor blades 2 and rotated relative to the airframe of the helicopter, and the actuator 4 is operated to reciprocate the spoiler 3 in response to the rotation timing or frequency of the rotor blade 2.

    Abstract: PROBLEM TO BE SOLVED: To realize miniaturization and light weight of a small pilotless plane suitable for hand throw staring or the like and portable by one person. SOLUTION: The small pilotless plane is provided with: all flying wing type main wing 1 being a camber wing type having an approximately flat lower surface, being thin toward a wing end in a tapered shape, having a wing front edge having a retreat angle and having a tailless type aerodynamincal surface of low aspect ratio; movable flaps 2 extending to both left and right sides at a rear edge part of the main wing over the approximately whole width and having a camber angle in at least horizontal flying; vertical stabilizer plates 3 arranged at both ends of the main wing; and two propellers 5 arranged on an upper surface of the main wing.

    Abstract: PROBLEM TO BE SOLVED: To optionally set and vary characteristics of a reaction force applied to an input part. SOLUTION: This system is equipped with an actuator 1 which has a servomotor rotating a screw shaft of a ball screw mechanism and supplies a reaction force to the input part while displacing the input part by the relative movement between a screw shaft and a ball nut through the operation of the servomotor, a load cell 4d which outputs an external force signal showing the strength of the external force applied to the input part, a potentiometer 1g which outputs a position signal showing the position of the input part, a driver 2a which operates the servomotor so that the difference between a position command signal and the position signal is eliminated, a reaction force controller 2b which generates and outputs the position command signal according to the difference between the signal generated by adding a position signal made variable in value according to a reaction force/displacement gradient command signal, a speed signal found from the position signal through differentiation processing and made adjustable in value according to an attenuation factor command signal, and a stationary reaction force command signal and the external force signal, and a computer 3 which outputs the reaction force/displacement gradient command signal, the attenuation factor command signal, and stationary reaction force command signal according to arbitrary settings.
