MISSILE FOR A NUCLEAR WARHEAD

MISSILE FOR A NUCLEAR WARHEADR-5M – the first in the world military equipment of the booster of the nuclear charge. Her starting weight was 28.6 tons, flight range is 1,200 km. Developed in 1954 – 1956, OKB-1 headed by S. P. Korolev on the basis of rocket R-5. In 1955, adopted in the USSR was adopted by the missile complex R-5, launch weight and range which were respectively 29 tons and 1200 km warhead Weight – about 1 ton. At start-up to a distance of 600 – 800 km, could be applied to two or four combat suspension with the use of a combined system, control the radio and Autonomous. Compared to previous products has significantly increased the accuracy of firing the missiles.

SIMPLE FREQUENCY COUNTER

A diagram of the frequency to control the frequencies in a relatively narrow range offers the magazine “Radio Fernsehen Elektronik” of the GDR. It contains all 7 elements. The device operates as follows. By using a series connected resistor R1 and Zener diode V1 of the input sinusoidal signal is converted into a rectangular amplitude Read more…

HAPPY “SEVEN”

HAPPY The eleventh June 1956, came a joint resolution of the CPSU Central Committee and the USSR Council of Ministers about the beginning of serial production of aircraft “C” under the designation su-7. 24 June-1 demonstrated at air parade in Tushino. The prototype was piloted by Nikolai Korovushkin. Structure of the planes was headed by Mikoyan E-2, because his design was still considered “the first fighter CB” of the country. But the real leadership was in the Dry – after all, the speed of 2M fighter Mikoyan not yet released.

ELLIPSOGRAPH

ELLIPSOGRAPHThe construction of the ellipses associated with certain difficulties, that’s why when drawing the axonometric images this process takes the lion’s share of time. I invented ellipsograph allows you to quickly draw ellipses of different sizes and with any ratio of the major and minor semi-axes. If necessary, the tool can be used as a regular compass to draw circles.

TRANSCEIVER — TO LIVE LONG

TRANSCEIVER — LIVE LONGTRANSCEIVER — LIVE LONGTransceiver SV MJ-2701 company MegaJet is designed for a supply voltage of 12.5 V, which, despite its “special” purpose to work as an automotive MW transceiver with power from the onboard network of the car 12, is not reasonable from the practical point of view and logic. As is well known to experienced Amateurs and professionals, the voltage of the car (meaning a car with a battery voltage of 12 VDC) when the engine is running can reach 15 In (these are the parameters of the relay controller charging battery). Consequently, some electronic and radio system (including transceivers) when operating in the vehicle fail.
