YAL-1
The Boeing YAL-1 airborne laser testbed was a modified Boeing 747-400F with a megawatt-class chemical oxygen iodine laser (COIL) mounted inside. It was primarily designed to test its feasibility as a missile defense system to destroy tactical ballistic missiles (TBMs) while in boost phase. The aircraft was designated YAL-1A in 2004 by the U.S. Department of Defense. The YAL-1 with a low-power laser was test-fired in flight at an airborne target in 2007. A high-energy laser was used to intercept a test target in January 2010, and the following month, successfully destroyed two test missiles. Funding for the program was cut in 2010 and the program was canceled in December 2011. It made its final flight on February 14, 2012, to Davis–Monthan Air Force Base near Tucson, Arizona, to be kept in storage at the "boneyard" operated by the 309th Aerospace Maintenance and Regeneration Group. It was ultimately scrapped in September 2014 after all usable parts were removed. Development ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boeing 747-400
The Boeing 747-400 is a large, long-range wide-body airliner produced by Boeing Commercial Airplanes, an advanced variant of the initial Boeing 747. The ''Advanced Series 300'' was announced at the September 1984 Farnborough Airshow, targeting a 10% cost reduction with more efficient engines and of additional range. Northwest Airlines became the first customer with an order for 10 aircraft on October 22, 1985. The first 747-400 was rolled out on January 26, 1988, and made its maiden flight on April 29, 1988. Type certification was received on January 9, 1989, and it entered service with Northwest on February 9, 1989. It retains the 747 airframe, including the 747-300 stretched upper deck, with winglets. The 747-400 offers a choice of improved turbofans: the Pratt & Whitney PW4000, General Electric CF6-80C2 or Rolls-Royce RB211-524G/H. Its two-crew glass cockpit dispenses with the need for a flight engineer. It typically accommodates 416 passengers in a three-class layo ...

Missile Defense Agency
The Missile Defense Agency (MDA) is a component of the Federal government of the United States, United States government's United States Department of Defense, Department of Defense responsible for developing a comprehensive Missile defense, defense against ballistic missiles. It had its origins in the Strategic Defense Initiative (SDI) which was established in 1983 by Ronald Reagan and which was headed by James A. Abrahamson, Lt. General James Alan Abrahamson. Under the Strategic Defense Initiative's Innovative Sciences and Technology Office headed by physicist and engineer Dr. James Ionson, the investment was predominantly made in basic research at national laboratories, universities, and in industry. These programs have continued to be key sources of funding for top research scientists in the fields of high-energy physics, advanced materials, nuclear research, supercomputing/computation, and many other critical science and engineering disciplines—funding which indirectly suppo ...

Boeing NC-135
The Boeing NC-135 and NKC-135 are special versions of the Boeing C-135 Stratolifter and Boeing KC-135 Stratotanker modified to operate on several different programs. Operational history Readiness Program In support of the U.S. Test Readiness Program that was initiated in response to the Partial Test Ban Treaty, Limited Test Ban Treaty (LTBT) of 1963, Sandia National Laboratories configured three NC-135 aircraft as flying laboratories to support atmospheric testing of nuclear weapons, should testing resume. These aircraft were based at Kirtland Air Force Base. Work was initiated in 1963 and the aircraft remained in service until 1976, flying principally for Sandia, the Los Alamos National Laboratory, and the Lawrence Livermore National Laboratory. The United States Atomic Energy Commission, Atomic Energy Commission (AEC) maintained controlling oversight of the NC-135 flight test aircraft. After 1976, the aircraft flew for Air Force Research Laboratory, Air Force Weapons Laborat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chemical Oxygen Iodine Laser
A chemical oxygen iodine laser (COIL) is a near–infrared chemical laser. As the beam is infrared, it cannot be seen with the naked eye. It is capable of output power scaling up to megawatts in continuous mode. Its output wavelength is 1315 nm, a transition wavelength of atomic iodine. Principles of operation The laser is fed with gaseous chlorine, molecular iodine, and an aqueous mixture of hydrogen peroxide and potassium hydroxide. The aqueous peroxide solution undergoes chemical reaction with chlorine, producing heat, potassium chloride, and oxygen in excited state, singlet delta oxygen. Spontaneous transition of excited oxygen to the triplet sigma ground state is forbidden giving the excited oxygen a spontaneous lifetime of about 45 minutes. This allows the singlet oxygen to transfer its energy to the iodine atoms present in the gas stream;the atomic transition 2P3/2 to 2P1/2 in atomic iodine is nearly resonant with the singlet oxygen, so the energy transfer duri ...

Airborne Laser
An airborne laser (ABL) is a laser system operated from a flying platform, as in the: * Soviet/Russian Beriev A-60 (1981, active) * American Boeing YAL-1 (2002-2012, scrapped) * An American modified NKC-135A unit (1975-1984, in storage.) Development Development of airborne lasers in the United States began with the Airborne Laser Laboratory (ALL) developed at the USAF Weapons Lab (AFWL), now known as Phillips Laboratory, in the late 1970's and early 1980's. The ALL was based on a carbon dioxide gas dynamic laser (GDL), operating at the infrared wavelength of 10.6 microns, and mounted on a modified Boeing KC-135 Stratotanker ( NC-135). It was successfully tested, and in 1983 destroyed five AIM-9 Sidewinder missiles and a simulated cruise missile ( BQM-34). Of note is that the ALL demonstrated one of the early uses of deformable mirror technology. To compensate for various atmospheric aberrations arising from turbulence and absorption of energy from the beam itself, it was n ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is an affinity group for contributors with shared goals within the Wikimedia movement. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within Wikimedia project, sibling projects such as Wiktionary, Wikiquote, Wikidata, and Wikisource. They also exist in different languages, and translation of articles is a form of their collaboration. During the COVID-19 pandemic, CBS News noted the role of Wikipedia's WikiProject Medicine in maintaining the accuracy of articles related to the disease. Another WikiProject that has drawn attention is WikiProject Women Scientists, which was profiled by ''Smithsonian Magazine, Smithsonian'' for its efforts to improve coverage of women scientists which the profile noted had "helped increase the number of female scientists on Wikipedia from around 1,600 to over 5,000".
