AR-15–style Rifle
An AR-15–style rifle is a lightweight semi-automatic rifle based on or similar to the Colt AR-15 design. The Colt model removed the selective fire feature of its predecessor, the original ArmaLite AR-15, which is a scaled-down derivative of the AR-10 design (by Eugene Stoner). It is closely related to the military M16 rifle. ArmaLite sold the patent and trademarks for both to Colt's Manufacturing Company in 1959 after the military rejected the design in favor of the M14. After most of the patents for the Colt AR-15 expired in 1977, many firearm manufacturers began to produce copies of the rifle under various names. While the patents are expired, Colt has retained the trademark to the ''AR-15'' name and is the sole manufacturer able to label their firearms as such. From 1994 to 2004, the Federal Assault Weapons Ban restricted the sale of the Colt AR-15 and some derivatives in the United States, although it did not affect rifles with fewer listed features. After the phrase "mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 , by 1966, the Lycoming T53-L-13, capable of , was being i ...

FH-1100
The Fairchild Hiller FH-1100 is a single-engine turbine, single two-bladed rotor, light helicopter that was designed and produced by the American aircraft manufacturer Fairchild Hiller in the 1960s. Originally designated as the ''Model 1100'', it was produced as the company's design submission for the United States Army's Light Observation Helicopter (LOH) program. It was one of the three winning designs in May 1961, after which the military designation ''Hiller YOH-5'' was assigned; the prototype performed its maiden flight on 21 January 1963. However, following extensive evaluations of the type, the Model 1100 did not receive a production contract after Hiller was underbid by the rival Hughes Tool Co. Aircraft Division's OH-6 Cayuse in 1965. Shortly following the purchase of Hiller Aircraft by Fairchild Engine and Airplane Corporation during 1964, the company decided to focus its efforts on the Model 1100, which was marketed as the FH-1100, towards other opportunities, bot ...

De Havilland Canada DHC-3 Otter
The de Havilland Canada DHC-3 Otter is a single-engined, high-wing, Propeller (aircraft), 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 De Havilland Canada DHC-2 Beaver, Beaver, including as a bush plane, while also being 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 t ...

Cessna 170
The Cessna 170 is an American single-engine, four seat, general aviation aircraft produced by the Cessna Aircraft Company between 1948 and 1956. It is the predecessor of the Cessna 172, the most produced aircraft in history, which replaced the 170 in production in 1956. Development 170 In late 1948, Cessna began sales of the 170, with a metal fuselage and tail and fabric-covered constant-chord wings. These earliest 170s were four-seat versions of the popular 140 with a more powerful Continental C145-2 and an extra interconnected fuel tank in one wing for a total of 36 gallons in three tanks. Like the 140, they were constructed of metal with fabric-covered wings supported by a "V" strut. 170A In 1949, Cessna began marketing the 170A, an all-metal 170 with zero- dihedral wing tapered outboard of the slightly-enlarged plain flaps with 50 degrees maximum deflection, two 21 gallon fuel tanks, and a single strut replacing the "V" strut of the 170.
