Civil Guard (Costa Rica)
Civil Guard (Spanish: ''Guardia Civil'') of Costa Rica was a gendarmerie type force responsible for both limited national defense and internal security missions. The Guardia Civil was the largest branch of the Fuerza Pública (Public Force) and was responsible for the defense of the nation in addition to its law enforcement duties. History The Civil Guard was founded in 1949 and combined the functions of an army, air force, navy, national police and coast guard. As formed, it was intended to have a very limited military capacity but have a primary internal security function. Its strength was initially 1,200, which remained relatively stable until the mid-1970s when it increased to 2,000. With its increased size came a tendency to assume a more military role.Armed Forces of Latin America by Adrian English The Civil Guard was organised along military lines and was deployed in seven provincial companies. Roughly 40 percent of the Civil Guard was deployed in or near the capital of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Browning Automatic Rifle
The Browning Automatic Rifle (BAR) is a family of American automatic rifles and machine guns used by the United States and numerous other countries during the 20th century. The primary variant of the BAR series was the M1918, chambered for the .30-06 Springfield rifle cartridge and designed by John Browning in 1917 for the American Expeditionary Forces in Europe as a replacement for the French-made Chauchat and M1909 Benét–Mercié machine guns that US forces had previously been issued. The BAR was designed to be carried by infantrymen during an assault Article by Maxim Popenker, 2014. advance while supported by the sling over the shoulder, or to be fired from the hip. This is a concept called " walking fire"—thought to be necessary for the individual soldier during trench warfare. The BAR never entirely lived up to the original hopes of the War Department as either a rifle or a machine gun. The US Army, in practice, used the BAR as a light machine gun, often fired from a ...

Piper Aztec
The Piper PA-23, named Apache and later Aztec, is an American four- to six-seat twin-engined light aircraft aimed at the general-aviation market. The United States Navy and military forces in other countries also used it in small numbers. Originally designed in the 1950s by the Stinson Aircraft Company, Piper Aircraft manufactured the Apache and a more powerful version, the Aztec, in the United States from the 1950s to the 1980s. Design and development The PA-23 was the first twin-engined Piper aircraft, and was developed from a proposed "Twin Stinson" design, inherited when Piper bought the Stinson Division of the Consolidated Vultee Aircraft Corporation. The prototype PA-23 was a four-seat, low-wing, all-metal monoplane with a twin tail, powered by two 125 hp Lycoming O-290-D piston engines; it first flew on March 2, 1952. The aircraft performed badly, so it was redesigned with a single vertical stabilizer and an all-metal rear fuselage and more powerful 150 hp Lycomi ...

Piper Seneca
The Piper PA-34 Seneca is a twin-engined light aircraft, produced in the United States by Piper Aircraft. It has been in non-continuous production since 1971. The Seneca is primarily used for personal and business flying. Development The Seneca was developed as a twin-engined version of the Piper Cherokee Six. The prototype was a Cherokee Six that had wing-mounted engines installed, retaining its nose engine. The prototype was flown as a tri-motor aircraft in the initial stages of the test-flying program. PA-34-180 Twin Six With the decision to abandon the three-engined design tested on the PA-32-3M, the PA-34 was developed as a twin-engined aircraft. The prototype PA-34-180 Twin Six, registered as ''N3401K'', first flew on 25 April 1967. The prototype had two Lycoming O-360 engines, a fixed nosewheel landing gear and a Cherokee Six vertical tail.

UH-1 Iroquois
The Bell UH-1 Iroquois (nicknamed "Huey") is a utility military helicopter designed and produced by the American aerospace company Bell Helicopter. It is the first member of the prolific Huey family, as well as the first turbine-powered helicopter in service with the United States military. Development of the Iroquois started in the early 1950s, a major impetus being a requirement issued by the United States Army for a new medical evacuation and utility helicopter. The Bell 204, first flown on 20 October 1956, was warmly received, particularly for the performance of its single turboshaft engine over piston engine-powered counterparts. An initial production contract for 100 ''HU-1A''s was issued in March 1960. In response to criticisms over the rotorcraft's power, Bell quickly developed multiple models furnished with more powerful engines; in comparison to the prototype's Lycoming YT53-L-1 (LTC1B-1) engine, producing 700 shp (520 kW), by 1966, the Lycoming T53-L-13, cap ...

Hughes 269
The Hughes TH-55 Osage is a piston-powered light training helicopter produced for the United States Army. It was also produced as the Model 269 family of light utility helicopters, some of which were marketed as the Model 300. The Model 300C was produced and further developed by Schweizer after 1983. Development In 1955, Hughes Tool Company's Aircraft Division carried out a market survey which showed that there was a demand for a low-cost, lightweight two-seat helicopter. The division began building the Model 269 in September 1955. It was initially designed with a fully glazed cockpit with seating for two pilots, or a pilot and passenger. It also had an open-framework fuselage and a three-blade articulated rotor. The prototype flew on 2 October 1956,"Military helicopters." ''Evergreen Aviation a ...

De Havilland Canada DHC-3 Otter
The de Havilland Canada DHC-3 Otter is a single-engined, high-wing, propeller-driven, short take-off and landing ( STOL) aircraft developed by de Havilland Canada. It was conceived to be capable of performing the same roles as the earlier and highly successful Beaver, including as a bush plane, but is overall a larger aircraft. Design and development The rugged single-engined, high-wing, propeller-driven DHC-3 Otter was conceived in January 1951 by de Havilland Canada as a larger, more powerful version of its highly successful DHC2 Beaver STOL utility transport. Dubbed the "King Beaver" during design, it would be the veritable "one-ton truck" to the Beaver's "half-ton" role. The Otter received Canadian certification in November 1952 and entered production shortly thereafter. Using the same overall configuration as the Beaver, the new, much heavier design incorporated a longer fuselage, greater-span wing, and cruciform tail. Seating in the main cabin expanded from six to 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cessna U-17
The Cessna 185 Skywagon is a six-seat, single-engined, general aviation light aircraft manufactured by Cessna. It first flew as a prototype in July 1960, with the first production model completed in March 1961. The Cessna 185 is a high-winged aircraft with non-retractable conventional landing gear and a tailwheel. Over 4,400 were built with production ceasing in 1985. When Cessna re-introduced some of its most popular models in the 1990s, the tailwheel equipped Cessna 180 and 185 were not put back into production. Design and development The aircraft is basically a Cessna 180 with a strengthened fuselage. The main difference between the two aircraft is the larger vertical fin on the 185 and the 300 hp (224 kW) Continental IO-520-D engine as opposed to the 230 hp (172 kW) Continental O-470-S fitted to the Cessna 180. The exception was that a Continental Motors IO-470-F engine of 260 hp (194 kW) was initially fitted until midway through the 196 ...
