    • 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.

    • PURPOSE: To achieve a speedy response and a high trim angle by developing a front wing after rocket motor combustion, sending the control signal of one control device to the actuator of two kinds of steering wings, namely front and rear wings, and simultaneously steering both the wings. CONSTITUTION: When the combustion completion signal of a rocket motor is received, a development mechanism 9 of a front wing 2 operates and the front wing 2 being folded inside is developed. As a result, the force-landing point of an airframe moves to a forward Xcp2 , and a distance to a gravity position xm2 is reduced from Δx2 to Δx3 , thus improving the response of the airframe. On rotation, an actuator 6a of a front wing 2 operates in a direction for raising the front edge of the front wing 2 due to a control signal from a control device 5 and an actuator 6 of a rear wing 4 operates in a direction for lowering the front edge of a rear wing 4. At this time, a clockwise moment required for balancing the airframe can be obtained from both of the front wing 2 and the rear wing 4, thus reducing the amount of steering of each wing as compared with a case where only one kind of steering wing is steered and hence relaxing a restriction to an elevation being generated from the stalling characteristics of wings and achieving a high trim angle.
