THE EJECTOR ON A COPY

EJECTOR of COPYUsing copy booster of the spaceship “Soyuz” in the class of models K-2 has, along with the advantages and disadvantages. In the manufacture of models, it is difficult to meet the launch weight of 120 g. But the complexity of the design allows (high quality models) to high poster ocenku. And we decided to build the engine in the junction of the two conical surfaces of the Central unit. Thus it was possible to refuse to load the nose of the model. The inner surface of the Central unit for protection against burn-out during operation of the engine covered office silicate glue.

ELECTROSTIMULATOR ON A COMPUTER

ELECTROSTIMULATOR ON THE COMPUTERDevices for influencing the so-called biologically active points (BAP) are known to many. Including those created by radio Amateurs. Circuitry underlying some BAT-stimulants, saw light in the pages of “Modeller-designer” (see “modelist-Konstruktor” No. 1 and 3 in 1998). However, to implement them was proposed, as a rule, “miscomputing” database. Well, if to approach from positions of today, when even personal supercomputer are not uncommon?

“BLACK CAT” OF THE WEHRMACHT

Of course, the “Panther” is one of the most famous heavy tanks, took part in the Second world war. The catalyst for the creation of this not provided in the system tank weapons of the Wehrmacht military machine was a Soviet medium tank T-34. His appearance on the Eastern front forced the Ministry of arms of Germany to suspend the work, which in 1937 led the company Henschl tank on a promising 30-ton class. Firm Rheinmetal July 18, 1941 received an order to develop a long-barreled 75-mm gun, able to penetrate 140 mm armor at a distance of 1000 m. the Daimler-Benz and MAN on November 25 were, in turn, issued orders for the 35-ton tank. Tactical and technical requirements for the new military machine has put forward the following: width up to 3150 mm, height 2990 mm, the engine capacity of 650-700 HP, armor protection, 40 mm, maximum speed 55 km/h. the Task was given the code name “Panther”.

Reconnaissance-torpedo bomber Blackburn Shark. In 1933 the air Ministry of great Britain has issued a document S. 15/33, which stipulates the requirements for a new scout-spotter-torpedo with a symbol T. S. R. (Torpedo-Spotter-Reconnaissance). According to these requirements, the aircraft had to operate from the decks of aircraft carriers, catapult ships and land-based airfields. This umieralnosci achieved by interchangeable wheel or float landing gear.
