2A3 Kondensator 2P
The 2A3 Kondensator 2P (russian: 2А3 «Конденсатор» - "Condenser" or "Capacitor") was a Soviet 406 mm self-propelled howitzer. Its GRAU designation is 2A3. Development The 2A3 originated during the Cold War as a response to the United States' new " Pentomic Division" tactical doctrine that emphasized heavy use of tactical nuclear weapons, including nuclear artillery. The US M65 cannon was introduced in 1952 and deployed in Germany in 1953. The Soviet Union started its own program to develop a 406mm self-propelled howitzer capable of firing nuclear projectiles, codenamed 'Objekt 271'. Grabin Design Bureau completed the artillery system in 1955. The 'Objekt 271' chassis from the Kotlin Design Bureau in Leningrad was completed soon thereafter. The unified system received the military industrial designation 2A3 and was completed in 1956 at the Kirov Works in Leningrad. Total production only amounted to four vehicles. Western observers got their first look at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Larsen Bay Airport
Larsen Bay Airport is a state-owned public-use airport located in Larsen Bay, a city in the Kodiak Island Borough of the U.S. state of Alaska. As per Federal Aviation Administration records, the airport had 1,700 passenger boardings (enplanements) in calendar year 2022. It is included in the National Plan of Integrated Airport Systems for 2011–2015, which categorized it as a ''non-primary commercial service'' airport (between 2,500 and 10,000 enplanements per year). Facilities and aircraft Larsen Bay Airport resides at elevation of 87 feet (27 m) above mean sea level. It has one runway designated 4/22 with a gravel surface measuring 2,690 by 75 feet (820 x 23 m). For the 12-month period ending December 31, 2006, the airport had 3,730 aircraft operations, an average of 10 per day: 52% air taxi and 48% general aviation.

Bessemer Airport
Bessemer Airport is a city-owned public-use airport located three nautical miles (6 km) southeast of the central business district of Bessemer, a city in Jefferson County, Alabama, United States. According to the FAA's National Plan of Integrated Airport Systems for 2009–2013, it is categorized as a ''reliever airport'' for the Birmingham-Shuttlesworth International Airport. Although many U.S. airports use the same three-letter location identifier for the FAA and IATA, this facility is assigned EKY by the FAA but has no designation from the IATA. Facilities and aircraft Bessemer Airport covers an area of at an elevation of 700 feet (213 m) above mean sea level. It has one runway designated 5/23 with an asphalt surface measuring 6,007 by 100 feet (1,831 x 30 m). An instrument landing system was installed in 2000.

Triode
A triode is an electronic amplifying vacuum tube (or ''valve'' in British English) consisting of three electrodes inside an evacuated glass envelope: a heated filament or cathode, a grid, and a plate (anode). Developed from Lee De Forest's 1906 Audion, a partial vacuum tube that added a grid electrode to the thermionic diode (Fleming valve), the triode was the first practical electronic amplifier and the ancestor of other types of vacuum tubes such as the tetrode and pentode. Its invention founded the electronics age, making possible amplified radio technology and long-distance telephony. Triodes were widely used in consumer electronics devices such as radios and televisions until the 1970s, when transistors replaced them. Today, their main remaining use is in high-power RF amplifiers in radio transmitters and industrial RF heating devices. In recent years there has been a resurgence in demand for low power triodes due to renewed interest in tube-type audio systems by audiophi ...
