Universal stand for micromotors. Tips for a modeler

Modeling

Often there is a need to break in the microengine, measure the number of revolutions and fuel consumption. It is not necessary to install the engine on the model for this. In the aircraft modeling circle of secondary school No. 112 of the city of Dnepropetrovsk, a stand was made, the design of which is easy to repeat. It can be used to launch and run in aircraft model engines with a volume of 1,5 to 10 cm3. The design of the stand is shown in the figure. It is based on a vise. It is best to use a table vise for wood, the parting plane of which is perpendicular to the front edge of the table.

The vise jaws are drilled with Ø 3,2 mm holes and M4 threaded. Squares are attached to the jaws with M4x20 screws, and the strips are screwed to them. The engine is attached to the paws with the help of pads.

Fix the vise on a solid base and, by turning the lead screw, set the bars to the width of the engine. Secure it with the straps. Tie a measuring tank with fuel with a rubber thread.

Universal stand (click to enlarge): 1 - M4X20 screw (12 pcs.), 2 - vise, 3 - square (2 pcs.), 4 - bar (2 pcs.), 5 - pad (2 pcs.), 6 - engine (tank not shown)

The stand is ready to go. It is necessary to test the engine on the street, at an open window or in a fume hood.

If necessary, the vise can also be used for its intended purpose, removing additional parts.

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. ... >>

Motion sickness glasses 12.07.2018

Citroen has created the Seetroen glasses, which help to cope with motion sickness.

Many people suffer from the so-called seasickness, or motion sickness: a feeling of nausea and motion sickness in transport. Citroen came up with a possible solution to the problem - they developed special glasses called Seetroen.

The white plastic frame of the glasses contains four rings filled with a blue liquid. The latter, according to Citroen, moves along the frontal and sagittal axes - left-right and back-and-forth - and creates an artificial horizon, which, in turn, allows you to resolve the conflict between the senses, which leads to unpleasant sensations in transport. According to the developers, Seetroen is able to eliminate the symptoms in just 10 minutes and cope in 95 percent of cases.

Seetroen price - 99 euros.
