2. Description of the Related Art Conventional roll control techniques for aircraft include a roll control technique using an aileron as shown in FIG. 3 and a roll control technique by a spoiler as shown in FIG.

In the conventional roll control technique using ailerons, as shown in FIG. 3, ailerons 3 as movable control surfaces are provided at the trailing edges of the left and right main wings 11 of the aircraft 10, and the ailerons 3 are provided in the left and right reverse directions. By moving to, the lift force of the left and right main wings is changed, as shown by the arrow, to cause the roll motion of the airframe.

In the conventional roll control technique using a spoiler, as shown in FIG. 4, a movable resistance plate called a spoiler 4 is provided in the middle of the upper surfaces of the left and right main wings 11, and the spoiler 4 on one side is raised. The roll motion of the airframe is performed by separating the flow on the upper surface of the main wing 11 and reducing the lift.

As shown in FIG. 5, the conventional aileron roll control technique has the following drawbacks. (1) Since the trailing edge of the outer wing portion of the main wing 11 is the aileron 3, the span size of the flap 5 is limited when the flap 5 is provided (see FIG. 5A). (2) Since the aileron 3 itself is a movable control surface, it is necessary to consider the rotation of the aileron 3 and the coupled flutter of the main wing 11 (see FIG. 5B). (3) It is necessary to consider the adverse effect of aileron. That is, as shown in FIGS. 5C to 5E, when the control rod 12 is moved laterally to lower one aileron 3, the aerodynamic force P A generated by the aileron 3 causes the main wing 1 to move upward.
A head-down moment acts on 1 (see FIG. 5 (d)).
When the main wing 11 is weak against twisting, the downward aerodynamic force P F generated by the twisting deformation of the main wing 11 increases, and the main wing 11
The total aerodynamic force generated by the aileron 3 and the aerodynamic force 3 may be downward, and the adverse effect phenomenon may occur (see FIG. 5 (e)), and it is necessary to consider it. FIG.
In (d) and FIG. 5 (e), α is the angle of attack.

On the other hand, another conventional roll control method using a spoiler has the following drawbacks. (1) By erecting the spoiler 4 which is a resistance plate, the air flow on the upper surface of the main wing is disturbed, and the lift force of the one side wing is reduced to roll, so that the lift force of the entire machine body is lowered (the altitude is lowered). (2) The effect is not good at low dynamic pressure.

According to the present invention, the balance weights installed between the right and left main wing spars are placed in a position that makes a pair of lines with respect to the machine axis during normal straight flight, and the balance weights around the machine axis due to the own weight of the left and right balance weights. Cancel the moment so that no rolling moment occurs on the aircraft. When a rolling moment is generated in the airframe, the left and right balance weights are independently moved in the wing direction, and a moment difference due to the weight of the left and right main wings around the machine axis is generated to generate the rolling moment in the airframe.

In this case, the roll rate can be changed not only by moving the balance weight only on one side of the main wing but also by moving the balance weights of both wings outward / inward at the same time.

Moreover, in the present invention, since the rolling moment is generated by the moment difference due to the movement of the balance weights of the left and right main wings and the aerodynamic force is not controlled, the reverse effect of the rudder does not occur.

As shown in FIG. 2, the balance weight 1 has an elastic shaft 15 of the main wing between the front and rear blade spars 14a and 14b.
The left and right wings can be independently moved in the spanwise direction by an actuator (not shown) along the guide rail 2 placed at a position. In FIG. 1B, 13 is the fuselage of the aircraft, and in FIG. 1B, the distribution of the lift L and the weight W is shown above and below the main wing 11.

In this embodiment, as shown by the solid line in FIG. 1 (a), when the left and right balance weights 1 are positioned in line with the machine axis, the distribution of the weight W is shown in FIG. 1 (b). )
As shown by the solid line, the balance is left and right, and the moment around the machine axis does not occur. However, by moving the weight 1 of the left main wing outward and moving the weight 1 of the right main wing inward as shown by the dotted line in FIG. 1 (a), as shown by the dotted line in FIG. 1 (b), The distribution of the weight W of the main wing 11 changes,
A moment is generated by the difference in weight distribution around the machine axis. Since the distribution of the lift force L hardly changes on the left and right main wings, it is possible to make a roll motion to the left around the machine axis as a resultant force.
