Accurate heading in any wind. Tips for a modeler

Modeling

Ship models are controlled by radio or by wire. Both types of communication require complex and expensive devices. Young technicians from the Yugoslav city of Zagreb made an attempt to simplify and make control more accessible to a wide range of modellers.

In essence, they did not invent anything new, but adapted the four-link widely known to everyone.

Let's face it.

Accurate heading in any wind
Autopilot: 1 - nose, 2 - horizontal partition, 3 - keel, 4 - lining, 5 - mast, 6 - sail, 7 - stern, 8 - rudder blade, 9 - deck, 10 - thrust, 11 - loop and 12 - board

Here is a model of a sports yacht, in which the sail and rudder are connected by a system of flexible rods in such a way that no matter which direction the wind blows (from the right, left side or from the stern), the mechanical device will turn the rudder in such a way that the model of its course will not change . You can verify this by using the device on your own model or by building a model of the same yacht.

Chassis

The main building material is wood. Parts 2-4, 7 and 9 should be cut out of 3mm plywood. Their developments are shown on the next page. Carefully transfer the contours to the plywood sheet and cut the blanks with a jigsaw. Carefully finish the cut edges with a rasp and sandpaper. Check that all mating surfaces fit exactly together.

The bar from which part 1 is machined, adjust to the required contours.

The mast and boom are wooden rods. Cut them with a sharp knife to the specified dimensions. The diameter of the mast at the base is 5 mm, and at the top - 3 mm. Boom diameter - 4 mm.

The parts are assembled using BF-2 glue or epoxy resin. Finishes the work by covering the body with 2-3 layers of oil varnish or drying oil. It will protect it from moisture.

The sail is cut out of thin silk of bright colors.

The four-link screed is made with a nylon cord. Its ends are fixed on the boom.

Hinges, hook on the steering wheel are made of steel wire with a diameter of 1 mm. The rudder blade is made of tin.

The assembled model does not require additional adjustment. Feel free to let her into the pond and, having set the course, make sure that no whim of the wind will now change it.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

Found the cause of autoimmune diseases 13.10.2017

Scientists from the US and Denmark, led by Soren Degn, of Aarhus University and Boston Children's Hospital, have found a trigger for autoimmune diseases, a key process that can be very helpful in their treatment if blocked.

For a long time, experts have been trying to understand the nature of epitope spread - a process in which the body's immune response spreads from a foreign object (for example, proteins of the cell membrane of viruses) to its own cells and tissues, leading to the development of the most dangerous autoimmune diseases. Degn and colleagues were able to shed light on this mechanism by studying the development of lupus in mice.

A key role in the immune response is played by B-lymphocytes, which, after antigen recognition, gather in special clusters in the lymph nodes - germinal centers - and begin to produce antibodies there. At the same time, different B-lymphocytes multiply rapidly and their clones compete with each other, so that in the end the clone that resists the antigen most effectively survives. When the system fails and the body mistakes its own normal protein for someone else's and harmful, B-lymphocytes, in the same way, begin to create a weapon against it - autoantibodies.

The Danish-American team followed the fate of different types of B-lymphocytes using the "confetti method", when they are stained under a microscope in different bright colors by attaching fluorescent marker proteins. It turned out that B-lymphocytes that produce autoantibodies and won their internal "arms race" with them, then begin to "recruit" their fellows - other B-lymphocytes - so that they also connect to the autoantibody response. This is how epitope propagation begins.

"It happens just like a thrown pebble creates circles on the water," Degn explained metaphorically.

This is an interesting and important discovery that could help develop a new way to fight autoimmune diseases. The idea is to somehow block the operation of the germinal centers. This would reset the "short-term memory" of the immune system, preventing epitope spread. However, the authors of the article themselves stipulate that it is still unclear how this can be done, and further research will be needed.
