Example Embodiment
[0020] Specific embodiment one: combination Figure 7 ~ Figure 10 To illustrate this embodiment, a quasi-flexible squid-like pulse jet thruster of this embodiment includes a silicone funnel 2, a squid-like mantle 3, and a cabin body 4. The squid-like mantle 3 is composed of a plurality of shape memory alloy wires 5, The silicone flexible body 6 is composed of a plurality of ribs 7, and the large diameter end of the silicone funnel 2 is connected to the inner wall of the open end of the cuttlefish mantle 3, and the cabin body 4 is arranged in the cuttlefish mantle 3. The multiple ribs 7 are evenly embedded in the cuttlefish mantle 3 along the circumferential direction of the cuttlefish mantle 3, each rib 7 is arranged along the generatrix direction of the cuttlefish mantle 3, and two adjacent ribs 7 They are connected by a shape memory alloy wire 5, and the shape memory alloy wire 5 is embedded in the cuttlefish mantle 3. See Figure 7 , The cabin 4 is equipped with a control de...
Example Embodiment
[0023] Specific implementation manner two: combination Picture 9 To describe this embodiment, the shape memory alloy wires 5 between two adjacent ribs 7 in this embodiment are arranged in a V shape. With this arrangement, the oblique wire cloth method at a certain angle to the rib 7 increases the length of the SMA wire, thereby increasing the relative movement distance between the two ribs 7. The two ends of the V-shaped arrangement of the shape memory alloy wires 5 are fixed on one rib 7, and the midpoint of the V-shaped arrangement of the shape memory alloy wires 5 is fixed on the other rib 7. The other composition and connection relationship are the same as in the first embodiment.
Example Embodiment
[0024] Specific implementation mode three: combination Figure 7 with Figure 8 To explain this embodiment, the pulse thruster of this embodiment also adds an underwater vector thrust nozzle 1 driven by a shape memory alloy. The underwater vector thrust nozzle 1 driven by the shape memory alloy is fixed on the small diameter end of the silicone funnel 2. on. With this setting, vector propulsion is realized. The shape memory alloy driven underwater vector thrust nozzle 1 adopts the vector thrust nozzle disclosed in the patent number ZL200610010360.5. Other components and connection relationships are the same as those in the first or second embodiment.
