CP-107 Argus
The Canadair CP-107 Argus (company designation CL-28) is a maritime patrol aircraft designed and manufactured by Canadair for the Royal Canadian Air Force (RCAF). The Argus served throughout the Cold War in the RCAF's Maritime Air Command and later the Canadian Force's Maritime Air Group and Air Command. Design and development In 1949, Canadair recognized that the RCAF would soon be looking for a replacement for the Avro Lancasters being used in the maritime patrol role and proposed the CL-29, a variant of the North Star, itself a variant of the Douglas C-54 Skymaster or DC-4 transport.Pickler, 1995, p.120 When the RCAF issued the specification in 1952, it was for a larger and more capable aircraft, and two proposals were received. These included a Lockheed Constellation variant from Lockheed, however its low speed handling was deemed inadequate by the RCAF, while Bristol proposed a variant of their Britannia airliner. However, concerns were raised over its floating controls, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Maritime Patrol Aircraft
A maritime patrol aircraft (MPA), also known as a patrol aircraft, maritime reconnaissance aircraft, maritime surveillance aircraft, or by the older American term patrol bomber, is a fixed-wing aircraft designed to operate for long durations over water in maritime patrol roles — in particular anti-submarine warfare (ASW), anti-surface warfare, anti-ship warfare (AShW), and search and rescue (SAR). In addition to dedicated airframes, mid-size and large business jets have been modified for MPA missions, offering rapid deployment, extended range, long endurance, and lower life-cycle costs. Among other maritime surveillance resources, such as satellites, ships, unmanned aerial vehicles (UAVs) and helicopters, the MPA is an important asset. To perform ASW operations, MPAs typically carry air-deployable Sonobuoy, sonar buoys as well as torpedoes and are usually capable of extended flight at low altitudes.

Titanium
Titanium is a chemical element; it has symbol Ti and atomic number 22. Found in nature only as an oxide, it can be reduced to produce a lustrous transition metal with a silver color, low density, and high strength, resistant to corrosion in sea water, aqua regia, and chlorine. Titanium was discovered in Cornwall, Great Britain, by William Gregor in 1791 and was named by Martin Heinrich Klaproth after the Titans of Greek mythology. The element occurs within a number of minerals, principally rutile and ilmenite, which are widely distributed in the Earth's crust and lithosphere; it is found in almost all living things, as well as bodies of water, rocks, and soils. The metal is extracted from its principal mineral ores by the Kroll and Hunter processes. The most common compound, titanium dioxide (TiO2), is a popular photocatalyst and is used in the manufacture of white pigments. Other compounds include titanium tetrachloride (TiCl4), a component of smoke screens and cata ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Naval Air Station Barbers Point
Naval Air Station Barbers Point , on O'ahu, home to John Rodgers (naval officer, World War I), John Rodgers Field (the original name of Honolulu International Airport), is a former United States Navy airfield closed in 1999, and renamed Kalaeloa Airport. Parts of the former air station serve as a Film studio, film and television studio for the Hawaii State Film Office. History Attack on Pearl Harbor On December 7, 1941, Barbers Point was one of the many targets attacked by the Japanese during the attack on Pearl Harbor. During the second wave, American pilots George Welch (pilot), George Welch and Kenneth M. Taylor, Kenneth Taylor engaged Japanese aircraft over Barbers Point, shooting down two aircraft. The Navy acquired the airfield in early 1943. At that time it consisted of two short runways and four hangars that were just two feet above tide, hightide. A PNAB civilian contractor started work by bringing a Dredging, dredge onto Keehi lagoon in February 1943. In April the m ...

New Zealand
New Zealand () is an island country in the southwestern Pacific Ocean. It consists of two main landmasses—the North Island () and the South Island ()—and List of islands of New Zealand, over 600 smaller islands. It is the List of island countries, sixth-largest island country by area and lies east of Australia across the Tasman Sea and south of the islands of New Caledonia, Fiji, and Tonga. The Geography of New Zealand, country's varied topography and sharp mountain peaks, including the Southern Alps (), owe much to tectonic uplift and volcanic eruptions. Capital of New Zealand, New Zealand's capital city is Wellington, and its most populous city is Auckland. The islands of New Zealand were the last large habitable land to be settled by humans. Between about 1280 and 1350, Polynesians began to settle in the islands and subsequently developed a distinctive Māori culture. In 1642, the Dutch explorer Abel Tasman became the first European to sight and record New Zealand. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
RNZAF Base Ohakea
RNZAF Base Ohakea is an operational base of the Royal New Zealand Air Force. Opened in 1939, it is located near Bulls, 25 km north-west of Palmerston North in the Manawatū. It is also used as an alternate airport for civilian aircraft. The base's motto is ''Defensio per vires'' (Latin for defence through strength). Early days An air base was originally proposed in the area in 1927, when Ohakea was selected as the most suitable site for a mooring mast for airships of the British Imperial Airship service. It was proposed to build one mast for a demonstration flight, with the potential for expansion to a full airship base with three masts, airship sheds and hydrogen production. However, there was no point in going ahead with the development of the site without a commitment from the Australian Government to build masts to provide bases in that country. When the Australian Government declined to build masts, the New Zealand Government declined likewise. 1930s development ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lockheed P-2 Neptune
The Lockheed P-2 Neptune (designated P2V by the United States Navy prior to September 1962) is a Maritime patrol aircraft, maritime patrol and anti-submarine warfare (ASW) aircraft. It was developed for the US Navy by Lockheed Corporation, Lockheed to replace the Lockheed Ventura, Lockheed PV-1 Ventura and PV-2 Harpoon, and was replaced in turn by the Lockheed P-3 Orion. Designed as a land-based aircraft, the Neptune never made a carrier landing, but a small number were converted and deployed as carrier-launched (using JATO assist), stop-gap nuclear bombers that would have to land on shore or ditch. The type was successful in export, and saw service with several armed forces. Design and development Development of a new land-based patrol bomber began early in World War II, with design work starting at Lockheed's Vega Aircraft Corporation, Vega subsidiary as a private venture on 6 December 1941.Scutts ''Air International'' January 1995, pp. 42–43. At first, the new design was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Eglin AFB
Eglin Air Force Base is a United States Air Force (USAF) base in the western Florida panhandle, located about southwest of Valparaiso in Okaloosa County. The host unit at Eglin is the 96th Test Wing (formerly the 96th Air Base Wing). The 96 TW is the test and evaluation center for Air Force air-delivered weapons, navigation and guidance systems, command and control systems, and Air Force Special Operations Command (AFSOC) systems. Eglin AFB was established in 1935 as the Valparaiso Bombing and Gunnery Base. It is named in honor of Lt. Col. Frederick I. Eglin who was killed in a crash of his Northrop A-17 attack aircraft on a flight from Langley to Maxwell Field, Alabama. History Creation and World War II Much of the base was part of a national forest until the outbreak of World War II in Europe when a proving ground for aircraft armament was established at Eglin. The U.S. Forest Service ceded over of the Choctawhatchee National Forest to the War Department ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Napier Nomad
The Napier Nomad is a British diesel engine, diesel aircraft engine designed and built by Napier & Son in 1949. They combined a piston engine with a turbine to recover energy from the exhaust and thereby improve fuel efficiency, fuel economy. Two versions were tested, the complex Nomad I which used two propellers, each driven by mechanically independent stages, and the Nomad II, using the turbo-compound principle which coupled the two parts to drive a single propeller. The Nomad II had the lowest specific fuel consumption (shaft engine), specific fuel consumption figures seen up to that time. Despite this the Nomad project was cancelled in 1955 having spent £5.1 million on development, as most interest had passed to turboprop designs. Design and development In 1945 the Air Ministry asked for proposals for a new class engine with good fuel economy. Curtiss-Wright was designing an engine of this sort of power known as the turbo-compound engine, but Sir Harry Ricardo, one of ...

Radial Engine
The radial engine is a reciprocating engine, reciprocating type internal combustion engine, internal combustion engine configuration in which the cylinder (engine), cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized Star polygon, star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings ar ...

Turbo-compound
A turbo-compound engine is a reciprocating engine that employs a turbine to recover energy from the exhaust gases. Instead of using that energy to drive a turbocharger as found in many high-power aircraft engines, the energy is instead sent to the output shaft to increase the total power delivered by the engine. The turbine is usually mechanically connected to the crankshaft, as on the Wright R-3350 Duplex-Cyclone, but electric and hydraulic power recovery systems have been investigated as well. As this recovery process does not increase fuel consumption, it has the effect of reducing the specific fuel consumption, the ratio of fuel use to power. Turbo-compounding was used for commercial airliners and similar long-range, long-endurance roles before the introduction of turbojet engines. Examples using the Duplex-Cyclone include the Douglas DC-7B and Lockheed L-1049 Super Constellation, while other designs did not see production use. Concept Most piston engines produce a hot ...
