Embodiment 1
[0054] as attached Figure 2-Figure 4 An adaptive and continuously adjustable cavitator structure shown includes a reference chassis 4 connected to each other, a rotatable telescopic component and a drive mechanism component, wherein,
[0055] The reference chassis 4 is installed between the rotatable telescopic part and the drive mechanism part, the geometric center of the reference chassis 4 is fixedly connected to the drive mechanism part, and the outer surface is in contact with the innermost surface of the rotatable telescopic part; In this embodiment, the reference chassis 4 has a circular shape, also called a reference disk.
[0056] In another embodiment of the present invention, the shape of the reference chassis is conical or concave cone-shaped.
[0057] The rotatable telescopic component includes three layers of fan-shaped groups that can move synchronously inward / outward. Each layer of the fan-shaped group is respectively connected to the drive link 5, and the ot...
Embodiment 2
[0078] as attached Figure 2-Figure 9 The self-adaptive and continuously adjustable cavitator structure shown includes a reference chassis 4 connected to each other, a rotatable telescopic part and a drive mechanism part. The difference from Embodiment 1 is that the rotatable telescopic part includes n layers A set of sectors that are cross-mounted on the reference chassis 4 and can move synchronously inwardly / outwardly, where n is an integer greater than 3; the process and principle of use are the same as those in Embodiment 1.
Embodiment 3
[0080] as attached figure 1 As shown in the underwater vehicle, the present invention also provides an underwater vehicle on the basis of Embodiment 1 or Embodiment 2, including the main body of the vehicle and the self-adaptive continuously adjustable The cavitator structure, the self-adaptive continuously adjustable cavitator structure is fixedly connected to the main body of the vehicle by welding, screwing or bonding, and the aircraft is coaxial with the reference chassis 4 .
[0081] Specifically, the main body of the navigation body includes a conical body 1 that is docked with the reference chassis 4 at one end and a cylindrical body 2 that is fixedly connected to the other end of the conical body 1. The cylindrical body 2 is far away from the One end of the conical projectile 1 is fixedly connected to the nozzle 10 of the navigation body; the reference chassis 4 is rigidly connected to the conical projectile 1; in this embodiment, the cylindrical body 2 is cylindrical;...
