The underwater glider, or aquon, is not a toy, but a practical mechanism that allows the swimmer to travel long distances and still develop sufficient speed. It is convenient in that it gives freedom to the hands, so that the swimmer can easily use both the speargun and the movie camera. Aquan requires less effort to move than fins.

Underwater glider

Akvon consists of an aluminum barrel 1 with a bearing 5, a wooden wing 2 with a keel 7, wooden stabilizers 10, 12, two plastic pressure plates 11, 13 and a nylon cord 17 with a spring 14.

Stabilizers give the glider stability, and movable wooden blades (wing), moving up and down and acting like twin oars, create traction.

When swimming with an aquon, the swimmer uses a mask and snorkel, his body makes movements similar to those of a dolphin, and he only controls the runes.

Installation

Start making Akvon with the preparation of materials and tools. All wooden structural elements are made of wood with a high specific gravity, such as birch or larch. The carrier pipe should be as thin-walled and light as possible. For the manufacture of pressure plates, 5 mm sheet plexiglass is suitable. All structural elements are connected with conventional screws and screws.

After you have made all the details, start assembling the akvon, following this sequence.

Assembly of the bow

Insert the bearing into the race 4 and fix it with screws. For more reliable fastening of the bearing in the cage, make small recesses for the screws on its outer ring. Put the bearing fixed in the holder onto the axle 3, install spacers 6 on both sides and connect it with screws to the wing.

Tail Assembly

Clamp the bar 8 in a vice (notches up), install the stabilizers and the support bar 9 and fasten the entire structure with screws. Fix the pressure plates 11 and 13 and the screw 15 for the spring.

Final assembly

Connect the wing and tail to the carrier tube 1 and install the keel 7. Hook the spring to the hook and connect it with a small piece of cord to the ring 16. Tie a knot at the end of another cord 17, thread the cord through the hole in the right plane of the wing and pass through the ring. Now, without tensioning the springs, pass the cord through the hole on the left wing plane and tie a second knot. Akvon assembled.

Adjustment

Dip the aquan into the water and, holding it by the tail section and the carrier pipe, begin to quickly raise it to the surface. The spring must be calibrated so that the wing can go down as far as it will go. The tension of the spring is adjustable with a cord.

The distance between the pressure plates and stabilizers is determined empirically. The plate should tightly fit the swimmer's legs, but in no case should they hold them. The design of our akvon is designed for the athlete to hold it with his feet and, if necessary, can immediately free himself from the glider.

The wooden elements of the aquon should not be painted and varnished, as the wood must absorb water. To prevent the aquon from floating up, hold it in the water before the walk.

If, nevertheless, the aquan emerges and it is difficult to control it, then weight the aquan wing with metal plates. But in no case do not tie it to your legs. This can lead to an accident!

Regularly clean the bearing from sand and dirt and lubricate it with technical grease, vaseline or CIATIM grease.

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

SCM-38I - RS-232/485 converter 19.11.2015

Digital signal conversion is widely used in industrial automation. RS232/RS485 converters are used to convert RS-232 interface signals to RS-485 interface signals during transmission and vice versa, for example, between a PLC and a personal computer or HMI panels.

RS-485 is a widely used interface in industrial networks due to reliable and at the same time cheap signal transmission between controllers and other microprocessor equipment over long distances (up to 1200 m without repeaters). RS-232 was originally used to exchange data between a personal computer and a modem at a distance of up to 15 m.

Autonics releases the SCM-38I converter designed for reliable conversion of RS232C to RS485 interface signals and vice versa.

Specifications:

Supply voltage - 12...24 V DC;
Switching speed 1200...115200 bps;
Type of communication - half-duplex;
Maximum distance - 800 m;
The number of plug-in modules - up to 32 pieces;
Connector on RS-232 side - D-SUB 9 connectors;
The connector on the RS-485 side is a 4-pin terminal with a screw fastening of wires.
