Problems solved by technology

The main problem in this respect is that no matter adding the sliding board or the tail control surface, it will increase the resistance on the moving body. stability
These cavitator structures only change the force of the cavitator from one side, and can only change the maneuverability of the moving body from one channel

Embodiment Construction

[0014] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0015] combine Figure 1~3 , the xy plane mechanism diagram of the cavitator is shown in the attachment figure 1 , this plane is mainly used to realize the climbing control force of the flying body, and the xz plane mechanism diagram and figure 1 have the same form. Since the movement of the xy and xz planes is controlled by separate motors, the mechanisms of xy and xz are independent of each other. See Figure 2 for their mechanical realization. The specific names of each number in the attached drawings are as follows: 1—the pull rod (prime mover) connecting the actuator (motor); 2—the fixed slider; 3—the connecting rod for realizing rotation; 4—the connecting rod for realizing plane movement; 5— Bending rod to realize rotation; 6—cavitator plane; 7—moving slider; 8—connecting rod to realize horizontal movement, the degree of freedom of this mechanism is calc...

Abstract

The invention aims to provide a four-degree-of-freedom cavitation device mechanism capable of changing control force. The four-degree-of-freedom cavitation device mechanism comprises an xy plane mechanism and an xz plane mechanism. The xy plane mechanism comprises a pull rod, a fixing slider, a rotating rod, a connecting rod, a curved rod, a moving slider and a horizontal moving rod. The fixing slider sleeves the pull rod, a first end of the pull rod is connected with a driving motor, a second end of the pull rod is hinged to the horizontal moving slider and the rotating rod respectively, the rotating rod is hinged to the connecting rod which is hinged to the curved rod, the curved rod is fixed at the curved point in a hinged manner and is hinged to the plane of a cavitation device, and the horizontal moving rod is hinged to the moving slider which is disposed on the plane of the cavitation device; the xz plane mechanism and the xy plane mechanism are identical in structure, and the rotating rod of the xy plane mechanism and a rotating rod of the xz plane mechanism form a 90-degree angle and are arranged in an intersected manner. The cavitation device mechanism features in four-degree-of-freedom movement, and both pitching channels and the control force of jaw channels can be increased.

Description

technical field [0001] The invention relates to a cavitator structure. Background technique [0002] The control technology under the condition of multiphase flow in water is an important key technology to improve and enhance the maneuverability of moving bodies in multiphase flow in water. For the moving body of multiphase flow in water, the control is mainly realized by the head cavitator rudder surface and the tail rudder surface. Since the tail rudder easily changes the flow stability during maneuvering, the head cavitator rudder is the main pitch and yaw control element. Correspondingly, in order to increase the speed of the flying body, the area of ​​the cavitator rudder surface is generally very small. From the way of control force generation, it can be seen that the control force generated by a cavitator with a small area is very limited, so the maneuverability of the multiphase flow moving body in water is greatly limited. This makes the moving body effectively a...
