TR TR TR TR DESCRIPTION DIAPHRAGM DRIVEN UNMANNED UNDERWATER VEHICLE Technical Field: The technical field to which the invention relates includes remote and autonomous controlled unmanned vehicles used in military and civilian underwater operations. This technical field includes research and development of the topics of motion-thrust, energy, body form-structure, and mission load integration according to the mission capabilities of the vehicles. Known State of the Technology: Underwater vehicles belonging to the described technical field are conventionally propeller-driven vehicles with a hydrodynamic hull form. Underwater vehicles, which are expected to navigate underwater and perform various maneuvers, have been designed to move with propellers since the first examples. Although the first submarine had a hull close to a spherical form, over time the designs approached the stern-drive type boat form and today it has turned into a type of this form with improved hydrodynamic properties. While the propulsion system used in the first submarines relied on human power, it was replaced by diesel, electric and nuclear power over time. Unmanned underwater vehicles, whose use has increased with the development of command-control-propulsion systems, today include different propulsion mechanisms and general shapes. These vehicles move either autonomously or connected to another mission platform with cable ties for command-control communication and energy transfer. Optical communication technique is still in the testing and development phase. According to operational requirements, the relationship of the propulsion units with the hull (e.g. water jet or external propeller unit integrated into the hull) determines the general shape. In these vehicles, movement is largely possible with the thrust provided by propeller units (ducted / open) or water jets with internal pumps. With the preliminary research, the new technical solutions brought by the invention have been put forward, especially considering the propulsion systems and formal configurations, in the examples given below. - It is fundamentally different from the invention in that its main configuration is in a submarine torpedo layout, in linear form, and the propulsion unit consists of a main propeller positioned at the stern of the vehicle. CHINA Patent No: CN110091974A The underwater vehicle, whose basic configuration consists of 3 rings placed inside each other, is driven by the propeller in the innermost ring. It is clearly different from the invention in terms of movement system and basic configuration. CHINA Patent No: CN110012207A Patent number granted Unmanned underwater vehicle is designed to move both in mid-water and on the seabed. Apart from the usual layout, the vehicle includes a ducted propeller set fixed in different vectors and additionally a tracked motion system to move on the seabed. The main body, which houses the battery and payload, is shown as an open frame. This design is radically different from the invention, especially in terms of the movement system. Chinese Patent No: CN110116793A The unmanned underwater vehicle, which has been granted patent number, is designed to move both in mid-water and on the seabed. A ducted propeller set fixed in different vectors for underwater swimming movement and a walking system consisting of six legs, each with two joints, for movement on the seabed are shown. The body of the vehicle, which includes motion, energy and other systems, is designed as an open frame. The vehicle design in question is fundamentally different from the invention in terms of movement system and body layout. Chinese Patent No: CN110076749A The motion system of this underwater vehicle, which was established by examining the jellyfish role model, contains 5 moving arms, each with 3 joints, placed in a star-segmental arrangement. Each arm contains soft tissues made of a mixture of silicone and magnetic powder. The vehicle changes location and performs certain maneuvers by stimulating these soft tissues with an external magnetic effect and moving the arms. Opening and closing the arms not only drives the vehicle under water, but also enables it to perform grasping and holding movements. The vehicle's energy and information processing system is located in the central head component. This vehicle design differs from the invention in terms of movement pattern and configuration. Korean Patent No: KR101283417BI The design, whose locomotion system was inspired by an underwater crustacean, contains 6 legs with 4 to 6 joints that can perform both underwater swimming and walking movements on the seabed. The design, which is suitable for use in deep sea bottom operations, has a hydrodynamic feature and a closed hull structure. The system shown consists of 3 main components: surface unit, intermediate (depressor) unit and underwater vehicle (crapster). Said vehicle design is radically different from the invention in terms of its movement system based on moving legs and its basic components. US Patent Number: U55995882A The vehicle, which has the patent number U55995882A, is a linear submarine ship layout, with wings for stabilization at the bow and aft, a tower structure containing an antenna, and a design that is driven by a single propeller at the stern. It is fundamentally different from the invention with its general linear layout, propeller drive and wing-controlled maneuvering system. Chinese Patent No: CN108725721 The motion system of the spherical underwater vehicle consists of 8 propeller propulsion units fixed in a radial arrangement. It is different from the invention because it has a propeller propulsion system. China Patent No: CN108791769 The underwater vehicle with patent number has a spherical body. The movement system consists of two co-axial and opposite-direction propeller units connected to a toothed outer pulley. With the help of toothed wheels, movement in different directions in the horizontal plane is achieved by changing the position of the outer pulley and therefore the propeller thrust vectors. Although the vehicle design includes a spherical body, it is different from the invention in terms of having separate-moving propulsion system and propeller units from the body. US Patent No: USÜ9650118 - The underwater vehicle with patent number was designed for mining exploration, and the configuration of the vehicle was created by considering the conditions of the deep sea (specified as 6000m). The movement of the vehicle is provided by water jets with propellers and pumps. Although it is similar to the invention in terms of the integration of the movement system into the body, it is different from the invention in terms of movement source and general layout. US Patent No: US4455962A - The spherical underwater vehicle with the patent number is driven by a single pump impeller. The vehicle performs basic direction changing maneuvers with the thrust provided by pumped water jets integrated into the body. The vehicle is different from the invention because it has a propeller motion system. Scientific Article: Development of a Spherical Underwater Robot Equipped with Multiple Vectored Water-Jet-Based Thrusters, 9651-3 0 The spherical underwater vehicle, which is the subject of the scientific article with the document number, is a mechanism with a changeable thrust vector, defined as a water jet, and a propeller placed in the channel. It is moved with . The vehicle design differs from the invention in that the ducted propeller-water jet units used in the propulsion system and the vectors of these units can be changed. Scientific Article: The Eyeball ROV: Design and Control of a Spherical Underwater Vehicle Steered by an Internal Eccentric Mass - The spherical underwater vehicle, which is the subject of the scientific article with the document number, is an observation vehicle that can precisely adjust its orientation with a variable internal weight. This vehicle differs clearly from the invention with its movable internal weight system and waterjet propulsion system, which is expected to be propeller-driven. Scientific Article: A ball-shaped underwater robot for direct inspection of nuclear reactors and other water-filled infrastructure Anirban Mazumdar, Aaron Fittery, Wyatt Ubellacker, H. Harry Asada IEEE (2013) DCI: Global underwater, which is the subject of a scientific article with a document number The robot is being developed at MIT to perform imaging inside water-filled structures (e.g. nuclear reactor cooling channels). The propulsion system of the spherical vehicle consists of a bi-directional pump containing impellers and controllable valves. The vehicle design differs from the invention in terms of its propulsion system. Technical Problems Intended to Solve: The technical problems that the invention aims to solve and the way they are solved are as follows: 1-Unmanned underwater vehicles encountered in technical field research are vehicles consisting of different components, designed on a single scale and only in certain dimensions. The production/assembly of the mentioned vehicles involves different steps and techniques. Different manufacturing points, materials, techniques, and combination details complicate the production process. The tools mentioned are only suitable for a specific mission profile. Adapting them to different task types is either impossible or possible with add-ons that would disrupt the integrity of the vehicle. The invention, which has a spherical form in which all its sub-components are integrated, provides the following advantages against the mentioned difficulties, thanks to its spherical basic form and physical layout: The body structure of the invention is produced entirely with 3D printing technology. This technology allows a large number of vehicles to be prepared in a short time and at low cost. The invention can be produced at different scales and can be easily adapted to different task requirements by changing the internal systems. 2-The conventional approach in unmanned underwater vehicles is to add the propulsion system and payload modules externally to the vehicle system. Due to outboard attachment units, the general form becomes complex and hydrodynamic properties are negatively affected. The balance of the vehicle is negatively affected. Underwater, the vehicle may get stuck on an obstacle (plant, net or similar debris) due to its complex shape. Deploying the vehicle to the duty point, removing it from the water and storing it becomes difficult. The spherical body form of the invention has positive hydrodynamic values in every direction of movement. All subsystems and payload are located inside the vehicle and at the center of gravity. Balance is constantly maintained. The invention integrates the propulsion system into the body shell and allocates the entire interior volume to vehicle subsystems and mission load. Thanks to the spherical form of the invention, storage and deployment and removal from water are simple. 3- In the underwater vehicle examples encountered in technical field research, the number of propulsion units (propeller or water jet) is increased in order to have precise maneuverability. As the number of thrust units increases, the mass of the vehicle increases, the range decreases, and the mission duration decreases. The propulsion units of the invention contain only the electro-active diaphragm (12), thrust channel (14) and position spring (24), the system provides precise maneuverability, long range and long mission duration without increasing the mass of the vehicle. 4- Due to the materials and mechanisms used in the underwater vehicle samples encountered in technical field research, the possible magnetic and sound footprints of the vehicles are large. - The vehicles in question cannot operate without being noticed. - The main body and thrust diaphragms of the invention consist of plastic material. It does not contain any mechanical mechanism inside. In this way, the magnetic and sound footprint is low. Description of the Pictures: The "Diaphragm Driven Unmanned Underwater Vehicle", which is the subject of the invention, is shown in the figures specified in the list: Figure 1 is the holistic view drawing of the underwater vehicle. In this way, the sub-components and layout on the spherical body surface of the vehicle are visible. Figure 2 is a cross-sectional drawing of the underwater vehicle. In this way, the vehicle's impulse cells, the vehicle's internal structure and system components are visible. Figure 3 is the detail-sectional drawings of the thrust cells of the underwater vehicle. These drawings show the components of the impulse cells and the positions they take during the impulse phases.

Its basic features are as follows: - The invention has a spherical basic shape (Figure 1). Motion and detection units are integrated into the spherical shell. The internal space of the spherical body is used for control, navigation and energy systems and the payload (Figure 2). o The thrust system of the invention consists of 32 thrust cells distributed in a geodesic arrangement (11) on the spherical shell of the vehicle to produce different thrust vectors. 0 Each thrust cell includes: 0 Thrust channel (14) o Thrust diaphragm (12) o Position Spring (24) o Generation of thrust (Figure 3) is based on the principle of flexible diaphragms absorbing water into the thrust channel and pushing it out. - The propulsion system provides the necessary electrical energy from the internal battery. - The invention can be produced in different sizes and adapted for different types of tasks. o The entire body of the invention can be produced with a 3D printing system. The invention basically has a spherical form. It contains 32 impulse cells placed in a geodesic pattern. The hull, where the detection, photovoltaic units and different task interfaces (16) are located in the same order, does not have a predetermined orientation (such as top-bottom, fore-aft, port-starboard) as in conventional surface and underwater vehicles. It can perform precisely controlled movement in all directions with the help of thrust units. The spherical body presents a form suitable for movement in the ambient fluid. The solid shell and flexible diaphragms that make up the body consist of different plastic materials. The solid shell is made of ABS (Acrylonitrile butadiene styrene) material, which is a type of thermo-plastic that can be printed with a 3D printer, while flexible diaphragms are manufactured by laminating different plastic layers. Thermoplastic polyurethane (TPU) material can be used in these flexible diaphragms. Soft marine creatures were taken as examples in the design of the diaphragm movement system, which is the distinguishing feature of the invention. The thrust cells of the system consist of thrust channel, diaphragm and plastic spring components. In each impulse cell, the ambient fluid is sucked into a space and pressed out with the help of flexible tissues, producing impulse in different vectors. Flexible diaphragms are obtained by laminating plastic materials with suitable elastic properties (12). The layer that provides movement to the diaphragm is another elastic polymer layer that is turned into an electro-active polymer by applying carbon powder. The electro-active polymer layer changes shape by stretching and gathering when electric current is passed through it. In this way, the laminated flexible diaphragms become concave with electrical energy and become convex with the help of a plastic spring when the current is cut off. The stress and strain behavior of elastic polymers compared to plastic materials according to Hook's law is shown in Table 1. I stamp! 1 .u h-iiiiiii I hiril. Iii «ni imiiiiviil nililirtl / iuiiiiin tiiIiI-iii Table 1. Stress and strain behavior graph of polymer materials (The marked curve indicates the thermoplastic elastomer material selected for flexible diaphragms) The unmanned underwater vehicle presented as an invention performs the basic movements as follows: - Movement 1: powered travel. Motion is achieved with the combined thrust vector that will be formed in the direction of the vehicle's travel as the flexible diaphragms absorb the water into the thrust channel and push it out. The vehicle performs basic depth maneuvers by fixing the positions of the diaphragms. When the vehicle makes all its diaphragms concave, the internal volume decreases, the density increases and the vehicle begins to dive. When the vehicle makes all its diaphragms convex, the internal volume increases, the density decreases, and the production method proposed for the Industrial Production Invention largely includes the newly developing 3D printing technology. The solid shell can be manufactured entirely and in 3D, including the thrust channels, from ABS or a similar solidifying polymer. Flexible diaphragms containing an electro-active polymer layer are envisaged to be laminated with two separate polymer layers (122-124) and eventually applied to the cells in the solid shell. In this way, it is thought that fast, economical and easy manufacturing will be possible by making the entire outer body made of plastic.TR TR TR TR
