Problem Statement
- Inefficient Propulsion: Conventional ROVs use rotary propellers that consume more power for required maneuverability, leading to lower propulsive efficiency.
- Complex Control Systems: Bio-inspired underwater vehicle designs offer higher efficiency but suffer from complex control system designs.
- Limited Battery Life: Efficient propulsion and maneuverability are crucial for autonomous underwater observation vehicles with limited battery capacity.
Technology
The present invention relates to a functionality-focused hybrid design of a bio-inspired underwater remotely operated vehicle.
Integrated Hybrid Propulsion System:
- The invention combines a bio-inspired caudal fin propulsion system with conventional rotary thrusters to achieve high efficiency for long-distance navigation and improved maneuverability for complex operations.
Simplified Control and Stability:
- The design minimizes control system complexity while enhancing stability and maneuverability by optimizing the placement and orientation of propulsion systems, hull shape, and weight distribution.
Modular and Adaptable Design:
- The vehicle’s modular design allows for easy replacement and customization of components, making it suitable for various underwater missions and applications with minimal modifications.
Key Features / Value Proposition
The main features of the invention are:
- Shape of the hull is streamlined and such that the vehicle has natural pitching for the vehicle to lean towards the direction of heaving.
- The flapping axis orientation and weight distribution is such that the amplitude of body oscillations while flapping is minimal.
- The bio-inspired flapping mechanism has a slotted lever and flexible fin, with the flexibility of the fin chosen such that the heave leads the pitch by about 90 degrees.
- The design is capable of moving straight long distances propelled by the efficient bio-inspired fin and maneuvering with rotary thrusters. This gives better overall efficiency for a given mission.
