1963 In Aviation
This is a list of aviation-related events from 1963. Events * Violating a 1959 requirement that all aircraft operating from the aircraft carrier ''Minas Gerais'' - which never has operated aircraft - belong to the Brazilian Air Force, the Brazilian Navy establishes an air group of its own for the carrier and smuggles aircraft purchased abroad into the country for the air group. Air force reconnaissance aircraft discover the naval carrier aircraft, causing tension between the two services. * The North Vietnamese Air Force and Air Defense Force merge to form a unified Air and Air Defense Force. January * January 2 – The Battle of Ap Bac in South Vietnam is the first time that Viet Cong forces stand and fight against a major South Vietnamese attack. At the outset, Viet Cong ground fire shoots down a United States Army UH-1 attack helicopter and four U.S. Army CH-21 transport helicopters as they arrive at their landing zone.

Fairchild C-123 Provider
The Fairchild C-123 Provider is an American military transport aircraft designed by Chase Aircraft and built by Fairchild Aircraft for the U.S. Air Force. In addition to its USAF service, which included later service with the Air Force Reserve and the Air National Guard, it went on to serve the U.S. Coast Guard and various air forces in Southeast Asia. During the War in Vietnam, the C-123 was used to deliver supplies, to evacuate the wounded, for agent insertions behind enemy lines, and was also used to spray Agent Orange. Design and development The C-123 Provider was designed originally as an assault glider aircraft for the United States Air Force (USAF) by Chase Aircraft as the XCG-20 (Chase designation MS-8 Avitruc)Gunston 1980a, p. 170. Two powered variants of the XCG-20 were developed during the early 1950s, as the XC-123 and XC-123A. The only difference was the class of engines used. The XC-123 used two Pratt & Whitney R-2800-23 air-cooled radial piston engines, whi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Piscataquis County, Maine
Piscataquis County ( ) is a county located in the U.S. state of Maine. As of the 2020 census, its population was 16,800, making it Maine's least-populous county. Its county seat is Dover-Foxcroft. The county was incorporated on March 23, 1838, taken from the western part of Penobscot County and the eastern part of Somerset County. It is named for an Abenaki word meaning "branch of the river" or "at the river branch." Originally, the county extended north to the Canada–US border, but in 1844 its northern portion was annexed by Aroostook County. In terms of land area, Piscataquis is one of the largest U.S. counties east of the Mississippi River. It is also one of two counties in the Northeast (and seven counties east of the Mississippi River) that meet Frederick Jackson Turner's requirements for "frontier" country – that is, having fewer than six inhabitants per square mile, the other being Hamilton County, New York. Baxter State Park, a large wilderness preserve, is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Elephant Mountain (Piscataquis County, Maine)
Elephant Mountain is a mountain located in Bowdoin College Grant West (Maine Township 8, Range 10, NWP) Piscataquis County, Maine. It is about southeast of Moosehead Lake, 2 miles southwest of Baker Mountain, and 5 miles west of White Cap Mountain. Elephant Mountain stands within the watershed of the Piscataquis River, which drains into the Penobscot River, and into Penobscot Bay. The west side of Elephant Mtn. drains into North Brook, thence into Upper Wilson Pond, Lower Wilson Pond, Big Wilson Stream, Sebec Lake, the Sebec River, and the Piscataquis River. The south and southeast faces of Elephant Mtn. drain into South Brook, thence into Upper Wilson Pond. The northeast faces of Elephant Mtn. drains into Baker Brook, thence into Mountain Pond, Mountain Pond Brook, the West Branch of the Pleasant River, and into the Piscataquis River. On January 24, 1963, a United States Air Force B-52 plane crashed on the mountain. There are piec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1963 Elephant Mountain B-52 Crash
On 24 January 1963 a United States Air Force Boeing B-52C Stratofortress with nine crew members on board lost its vertical stabilizer due to buffeting stresses during turbulence at low altitude and crashed on Elephant Mountain in Piscataquis County, Maine, United States, from Greenville. The pilot and the navigator survived the accident. Training mission The crew's training mission was called a ''Terrain Avoidance Flight'' to practice techniques to penetrate ''Advanced Capability Radar'' (ACR) undetected by Soviet air defense during the Cold War. ACR training flights had already been made over the West Coast of the United States on ''Poker Deck'' routes. This was to be the first low-level navigation flight, utilizing terrain-following radar, in the Eastern United States. The crew, consisting of two 99th Bombardment Wing Standardization Division crews based at Westover Air Force Base, Massachusetts, and two instructors from the 39th Bombardment Squadron, 6th Strategic Aeros ...

Turbulence
In fluid dynamics, turbulence or turbulent flow is fluid motion characterized by chaotic changes in pressure and flow velocity. It is in contrast to laminar flow, which occurs when a fluid flows in parallel layers with no disruption between those layers. Turbulence is commonly observed in everyday phenomena such as surf, fast flowing rivers, billowing storm clouds, or smoke from a chimney, and most fluid flows occurring in nature or created in engineering applications are turbulent. Turbulence is caused by excessive kinetic energy in parts of a fluid flow, which overcomes the damping effect of the fluid's viscosity. For this reason, turbulence is commonly realized in low viscosity fluids. In general terms, in turbulent flow, unsteady vortices appear of many sizes which interact with each other, consequently drag due to friction effects increases. The onset of turbulence can be predicted by the dimensionless Reynolds number, the ratio of kinetic energy to viscous damping ...

Vertical Stabilizer
A vertical stabilizer or tail fin is the static part of the vertical tail of an aircraft. The term is commonly applied to the assembly of both this fixed surface and one or more movable rudders hinged to it. Their role is to provide control, stability and trim in yaw (also known as directional or weathercock stability). It is part of the aircraft empennage, specifically of its Stabilizer (aeronautics), stabilizers. The vertical tail is typically mounted on top of the rear fuselage, with the horizontal stabilizers mounted on the side of the fuselage (a configuration termed "conventional tail"). Other configurations, such as T-tail or twin tail, are sometimes used instead. Vertical stabilizers have occasionally been used in Motorsport, motor sports, with for example in Le Mans Prototype, Le Mans Prototype racing. Function Principle The vertical tail of an aircraft typically consists of a fixed vertical stabilizer or fin on which a movable rudder is mounted. A trim tab may s ...

Boeing B-52 Stratofortress
The Boeing B-52 Stratofortress is an American long-range, subsonic aircraft, subsonic, jet-powered strategic bomber. The B-52 was designed and built by Boeing, which has continued to provide support and upgrades. It has been operated by the United States Air Force (USAF) since 1955 and was flown by NASA from 1959 to 2007. The bomber can carry up to of weapons and has a typical Range (aeronautics), combat range of around without aerial refueling. After Boeing won the initial contract in June 1946, the aircraft's design evolved from a straight wing, straight-wing aircraft powered by six turboprop engines to the final prototype YB-52 with eight turbojet engines and swept wings. The B-52 took its maiden flight in April 1952. Built to carry nuclear weapons for Cold War Nuclear strategy, deterrence missions, the B-52 Stratofortress replaced the Convair B-36 Peacemaker. The bombers flew under the Strategic Air Command (SAC) until it was disestablished in 1992 and its aircraft abso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

The United States Air Force (USAF) is the Air force, air service branch of the United States Department of Defense. It is one of the six United States Armed Forces and one of the eight uniformed services of the United States. Tracing its origins to 1 August 1907, as a part of the United States Army Signal Corps, the USAF was established by transfer of personnel from the Army Air Forces with the enactment of the National Security Act of 1947. It is the second youngest branch of the United States Armed Forces and the fourth in United States order of precedence, order of precedence.
