ACES II
ACES II is an ejection seat system manufactured by the Collins Aerospace division of Raytheon Technologies (RTX). ACES is an acronym for Advanced Concept Ejection Seat. It is used in Fairchild Republic A-10 Thunderbolt II, McDonnell Douglas F-15 Eagle, General Dynamics F-16 Fighting Falcon, Lockheed Martin F-22 Raptor, Lockheed F-117 Nighthawk, Rockwell B-1 Lancer, WB-57, Northrop Grumman B-2 Spirit, and Mitsubishi F-2 aircraft. Over 10,000 ACES II seats have been produced with over 5,000 actively flying throughout the world as of 2013. It is known throughout the industry as the lowest life cycle cost third generation seat due to the USAF owning the rights to the seat, facilitating competitive replacement part procurement. In addition, the buying power of 5,000 in-service seats and previous service life extension programs have further driven down support costs. The seat is considered ''third generation'' and includes advanced features. For example, it senses the conditions ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Northrop Grumman B-2 Spirit
The Northrop (later Northrop Grumman) B-2 Spirit, also known as the Stealth Bomber, is an American heavy strategic bomber, featuring low-observable stealth technology designed to penetrate dense anti-aircraft defenses. A subsonic flying wing with a crew of two, the plane was designed by Northrop, later Northrop Grumman, and produced from 1987 to 2000. The bomber can drop conventional and thermonuclear weapons, such as up to eighty Mk 82 JDAM GPS-guided bombs, or sixteen B83 nuclear bombs. The B-2 is the only acknowledged aircraft that can carry large air-to-surface standoff weapons in a stealth configuration. Development began under the Advanced Technology Bomber (ATB) project during the Carter administration, which cancelled the Mach 2-capable B-1A bomber in part because the ATB showed such promise. But development difficulties delayed progress and drove costs up. Ultimately, the program produced 21 B-2s at an average cost of $2.13 billion (in 1997 dollars), includ ...

Goodrich Corporation
The Goodrich Corporation, formerly the B.F. Goodrich Company, was an American manufacturing company based in Charlotte, North Carolina. Founded in Akron, Ohio in 1870 as Goodrich, Tew & Co. by Benjamin Goodrich, the company name was changed to the "B.F. Goodrich Company" in 1880, to BFGoodrich in the 1980s, and to "Goodrich Corporation" in 2001. Originally a rubber manufacturing company known for automobile tires, the company diversified its manufacturing businesses throughout the twentieth century and sold off its tire business in 1986 to focus on its other businesses, such as aerospace and chemical manufacturing. The BFGoodrich brand name continues to be used by Michelin, who acquired the tire manufacturing business in 1988. Following the acquisition by United Technologies in 2012, Goodrich became a part of UTC Aerospace Systems. In 1869, Benjamin Goodrich purchased the Hudson River Rubber Company, a small business in Hastings-on-Hudson, New York. The follo ...

Equivalent Airspeed
Equivalent airspeed (EAS) is calibrated airspeed (CAS) corrected for the compressibility of air at a non-trivial Mach number. It is also the airspeed at sea level in the International Standard Atmosphere at which the dynamic pressure is the same as the dynamic pressure at the true airspeed (TAS) and altitude at which the aircraft is flying. In low-speed flight, it is the speed which would be shown by an airspeed indicator with zero error.Houghton, E.L. and Carpenter, P.W. (1993), ''Aerodynamics for Engineering Students'', Section 2.3.3, Butterworth-Heinemann, Oxford UK. It is useful for predicting aircraft handling, aerodynamic loads, stalling etc. EAS = TAS \times \sqrt where: \rho\, is actual air density. \rho_0\, is standard sea level density (1.225 kg/m3 or 0.00237 slug/ft3). EAS is a function of dynamic pressure. EAS = \sqrt where: \, is dynamic pressure q = \tfrac12\, \rho\, v^, EAS can also be obtained from the aircraft Mach number and static pressure. EA ...

Indicated Airspeed
Indicated airspeed (IAS) is the airspeed of an aircraft as measured by its pitot-static system and displayed by the airspeed indicator (ASI). This is the pilots' primary airspeed reference. This value is not corrected for installation error, instrument error, or the actual encountered air density, being instead calibrated to always reflect the adiabatic compressible flow of the International Standard Atmosphere at sea level. It uses the difference between total pressure and static pressure, provided by the system, to either mechanically or electronically measure dynamic pressure. The dynamic pressure includes terms for both density and airspeed. Since the airspeed indicator cannot know the density, it is by design calibrated to assume the sea level standard atmospheric density when calculating airspeed. Since the actual density will vary considerably from this assumed value as the aircraft changes altitude, IAS varies considerably from true airspeed (TAS), the relative velocity ...

United States Air Force
The United States Air Force (USAF) is the air service branch of the United States Armed Forces, and is one of the eight uniformed services of the United States. Originally created on 1 August 1907, as a part of the United States Army Signal Corps, the USAF was established as a separate branch of the United States Armed Forces in 1947 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 order of precedence. The United States Air Force articulates its core missions as air supremacy, global integrated intelligence, surveillance and reconnaissance, rapid global mobility, global strike, and command and control. The United States Air Force is a military service branch organized within the Department of the Air Force, one of the three military departments of the Department of Defense. The Air Force through the Department of the Air Force is headed by the civilian Secretary of the Air Force ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitsubishi F-2
The Mitsubishi F-2 is a multirole fighter derived from the General Dynamics F-16 Fighting Falcon, and manufactured by Mitsubishi Heavy Industries and Lockheed Martin for the Japan Air Self-Defense Force, with a 60/40 split in manufacturing between Japan and the United States. The basis of the F-2's design is the F-16 Agile Falcon, an unsuccessful offer by General Dynamics to provide a low-cost alternative for the Advanced Tactical Fighter (ATF) competition. Production started in 1996 and the first aircraft entered service in 2000. The first 76 aircraft entered service by 2008, with a total of 98 airframes produced. The first active electronically scanned array (AESA) radar on a combat aircraft was the J/APG-1 introduced on the Mitsubishi F-2 in 1995. The F-2 is nicknamed "Viper Zero", a reference to the F-16's unofficial nickname of "Viper" and the Mitsubishi A6M Zero. Development US–Japan negotiations The JASDF and its contractors considered developing a Japanese-designed, J ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
WB-57
The Martin B-57 Canberra is an American-built, twin-engined tactical bomber and reconnaissance aircraft that entered service with the United States Air Force (USAF) in 1953. The B-57 is a license-built version of the British English Electric Canberra, manufactured by the Glenn L. Martin Company. Initial Martin-built models were virtually identical to their British-built twinjet counterparts; Martin later modified the design to incorporate larger quantities of US-sourced components and produced the aircraft in several different variants. The B-57 Canberra holds the distinction of being the first jet bomber in U.S. service to drop bombs during combat. The Canberra was used extensively during the Vietnam War in a bombing capacity; dedicated versions of the type were also produced and served as high-altitude aerial reconnaissance platforms (the Martin RB-57D Canberra), and as electronic warfare aircraft. The B-57 Canberra was also sold to export customers abroad; further combat us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ejection Seat
In aircraft, an ejection seat or ejector seat is a system designed to rescue the aircraft pilot, pilot or other aircrew, crew of an aircraft (usually military) in an emergency. In most designs, the seat is propelled out of the aircraft by an explosive charge or rocket motor, carrying the pilot with it. The concept of an ejectable escape crew capsule has also been tried. Once clear of the aircraft, the ejection seat deploys a parachute. Ejection seats are common on certain types of military aircraft. History A bungee cord, bungee-assisted escape from an aircraft took place in 1910. In 1916, Everard Calthrop, an early inventor of parachutes, patented an ejector seat using compressed air. The modern layout for an ejection seat was first introduced by Romanian inventor Anastase Dragomir in the late 1920s. The design featured a ''parachuted cell'' (a dischargeable chair from an aircraft or other vehicle). It was successfully tested on 25 August 1929 at the Paris-Orly Airport ne ...

Rockwell B-1 Lancer
The Rockwell B-1 Lancer is a supersonic variable-sweep wing, heavy bomber used by the United States Air Force. It is commonly called the "Bone" (from "B-One"). It is one of three strategic bombers serving in the U.S. Air Force fleet along with the B-2 Spirit and the B-52 Stratofortress . The B-1 was first envisioned in the 1960s as a platform that would combine the Mach 2 speed of the B-58 Hustler with the range and payload of the B-52, and was meant to ultimately replace both bombers. After a long series of studies, Rockwell International (now part of Boeing) won the design contest for what emerged as the B-1A. This version had a top speed of Mach 2.2 at high altitude and the ability to fly for long distances at Mach 0.85 at very low altitudes. The combination of the high cost of the aircraft, the introduction of the AGM-86 cruise missile that flew the same basic speed and distance, and early work on the B-2 stealth bomber reduced the need for the B-1. The program was cancele ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lockheed F-117 Nighthawk
The Lockheed F-117 Nighthawk is a retired American single-seat, twin-engine stealth attack aircraft developed by Lockheed's secretive Skunk Works division and operated by the United States Air Force (USAF). It was the first operational aircraft to be designed with stealth technology. The F-117 was based on the ''Have Blue'' technology demonstrator. The Nighthawk's maiden flight took place in 1981 at Groom Lake, Nevada, and the aircraft achieved initial operating capability status in 1983. The aircraft was shrouded in secrecy until it was revealed to the public in 1988. Of the 64 F-117s built, 59 were production versions, with the other five being prototypes. The F-117 was widely publicized for its role in the Gulf War of 1991. Although it was commonly referred to as the "Stealth Fighter", it was strictly an attack aircraft. F-117s took part in the conflict in Yugoslavia, where one was shot down by a surface-to-air missile (SAM) in 1999. The U.S. Air Force retired the F-1 ...
