The Stirling engine is a heat engine invented by Robert Stirling in 1816. It differs from the internal combustion engine because the fuel burns outside the engine, making it much easier to manufacture. There are Stirling engines that run from the heat of your hands, although they are a little harder to build. The Stirling engine would be a good addition to any collection of those who like to make things with their hands.

This gave the opportunity to provide good maneuverability and rate of climb. Technical Council Aviatrust Polikarpov suggested to consider the inclusion of a new fighter in the prototype development plan and approached the BBC with a request to present to him their tactical and technical requirements. Design And-5 plan had to be completed in November 1929: in October of next year, it was required to produce to the test.

SIMPLEST ANTI-THEFT DEVICE

SIMPLEST ANTI-THEFT DEVICEWhat devices are invented so that the attackers couldn’t steal a car. Steering lock, gear shift knob, wheels, dodgy electrics off, the impact on the psyche of a siren, light shows and much, much more. And yet… the thefts occur.

Here the Naval General staff to do a break not want. Immediately after the drawing, “Washington naked” went to the shipyard, the engineers began developing a new project. This time it was assumed that the following “desyatitysyachnye” will be much more secure.
