JT15D Thrust Reverser Functional Test
The Pratt & Whitney Canada JT15D is a small turbofan engine built by Pratt & Whitney Canada. It was introduced in 1971 at thrust, and has since undergone a series of upgrades to just over thrust in the latest versions. It is the primary powerplant for a wide variety of smaller jet aircraft, notably business jets. Design and development When it first ran in 1967 the JT15D was rare among turbofan engines in that it uses a centrifugal compressor as its high-pressure stage. About 70% of the air passing through the fan goes down the bypass duct. The JT15D-4 and later variants use a "booster" axial stage behind the fan which runs at the same speed as the fan and directs the remaining 30% of the air into the high-pressure compressor, after which it passes into a reverse-flow annular combustor. The hot gases flow through a high-pressure turbine that drives the centrifugal compressor, and a low-pressure turbine that drives the fan and booster. The engine was first run in August 1967 ...

WikiProject Aircraft
A WikiProject, or Wikiproject, is a Wikimedia movement affinity group for contributors with shared goals. WikiProjects are prevalent within the largest wiki, Wikipedia, and exist to varying degrees within sister 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'' 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". On Wikipedia Some Wikipedia WikiProjects are substantial enough to engage in cooperative activities with outside organizations relevant to the field at issue. For e ...

Northrop Grumman X-47A Pegasus
The Northrop Grumman X-47 is a demonstration unmanned combat aerial vehicle. The X-47 began as part of DARPA's J-UCAS program, and is now part of the United States Navy's UCAS-D program to create a carrier-based unmanned aircraft. Unlike the Boeing X-45, initial Pegasus development was company-funded. The original vehicle carries the designation X-47A Pegasus, while the follow-on naval version is designated X-47B. Design and development The US Navy did not commit to practical UCAV efforts until mid-2000, when the service awarded contracts of US$2 million each to Boeing and Northrop Grumman for a 15-month concept-exploration program. Design considerations for a naval UCAV included dealing with the corrosive salt-water environment, deck handling for launch and recovery, integration with command and control systems, and operation in a carrier's high electromagnetic interference environment. The Navy was also interested in using their UCAVs for reconnaissance missions, penetratin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Honda MH02
The Honda MH02 was an experimental business jet built by Honda, in cooperation with Mississippi State University, to research engine placement and composite construction. The prototype was completed in 1992, making its first flight on 5 March 1993. The MH02 was never intended for production, but was nonetheless the first all-composite light business jet to fly; by 1996 over 170 test flight hours were accumulated on the airframe. Aside from the already unusual above-the-wing engine mounts, the design features a T-tail and a forward-swept wing. The aircraft was deregistered and exported to Japan in 1998. Specifications (MH02) See also * VFW-Fokker 614: Twin overwing jet engines * HFB 320 Hansa Jet The HFB 320 Hansa Jet is a twin-engine, ten-seat business jet that was designed and produced by German aircraft manufacturer Hamburger Flugzeugbau between 1964 and 1973.

Boeing Bird Of Prey
The Boeing Bird of Prey was a black project aircraft, intended to demonstrate stealth technology. It was developed by McDonnell Douglas and Boeing in the 1990s."Boeing Unveils Bird of Prey Stealth Technology Demonstrator" . Boeing, October 18, 2002. The company provided $67 million of funding for the project; it was a low-cost program compared to many other programs of similar scale. It developed technology and materials which would later be used on Boeing's X-45 unmanned combat air vehicle. As an internal project, this aircraft was n ...

Alenia Aermacchi M-311
The Aermacchi M-345 is a turbofan-powered military trainer aircraft. It is a development of the SIAI-Marchetti S.211. Development Origins During 1997, Italian aircraft manufacturer Aermacchi acquired SIAI-Marchetti; this purchase included the rights to the latter's S.211, a jet-powered trainer aircraft. In 2004, the company announced its intention to develop an improved version of the S.211, then referred to as the M-311. At the time, Aermacchi was also developing the M-346 Master, which serves as a lead-in fighter trainer; considerably smaller than the M-346, the M-311 was intended to perform both the basic and advanced training syllabus, as well as tactical training functions, as an alternative to single-engined turboprop-powered competitors.Collins, Peter"FLIGHT TEST: Alenia Aermacchi M-311 - Bridging the gap."''Flight International'', 7 May 2007.Doyle, Andrew"M-311 set to face pilot scrutiny."''Flight International'', 13 September 2005.

Aérospatiale Corvette
The Aérospatiale SN 601 Corvette is a French business jet of the early 1970s developed and manufactured by aerospace manufacturer Aérospatiale. Sales of the type were disappointing, leading to only 40 Corvettes being constructed, including the prototypes, prior to production being terminated. In response to an open request by the French government for a compact twin-turbofan engine-equipped liaison/ trainer aircraft, aircraft manufacturers Sud Aviation and Nord Aviation decided to embark upon development of a new business jet that could also fulfil the government demand as well. The joint venture's design, initially designated as the ''SN 600 Diplomate'', was first publicly displayed at the 1968 Hanover ILA Air Show. On 16 July 1970, the prototype SN 600 performed the type's maiden flight; on 23 March 1971, this prototype was lost during a test flight. A pair of improved ''SN 601'' prototypes were then constructed; on 20 December 1972, the first of these prototypes conducted ...

Solid Air (537497676)
Solid is one of the four fundamental states of matter (the others being liquid, gas, and plasma). The molecules in a solid are closely packed together and contain the least amount of kinetic energy. A solid is characterized by structural rigidity and resistance to a force applied to the surface. Unlike a liquid, a solid object does not flow to take on the shape of its container, nor does it expand to fill the entire available volume like a gas. The atoms in a solid are bound to each other, either in a regular geometric lattice (crystalline solids, which include metals and ordinary ice), or irregularly (an amorphous solid such as common window glass). Solids cannot be compressed with little pressure whereas gases can be compressed with little pressure because the molecules in a gas are loosely packed. The branch of physics that deals with solids is called solid-state physics, and is the main branch of condensed matter physics (which also includes liquids). Materials science ...

Rockwell Ranger 2000
The Rockwell Ranger 2000 was a jet trainer candidate for the United States Joint Primary Aircraft Training System proposed by Rockwell International with assistance from Rhein-Flugzeugbau GmbH (RFB) in Germany. Design and development The United States military issued a Request for proposal for a jet trainer for use by the United States Air Force and United States Navy. Rockwell responded with the Ranger 2000 two-seat, single engined cantilever monoplane. The design was based on the work of RFB, in particular the RFB Fantrainer and the prototypes were built in Germany. The Ranger 2000 was powered by a Pratt & Whitney Canada JT15D-5C turbofan mounted in the rear fuselage and fed by two air intakes above the wing roots. It used retractable tricycle landing gear, the wing was straight and low-mounted, and the crew of two sat in tandem with the rear instructor raised to maintain visibility. Both crew had a Stencel zero-zero ejection seat. The aircraft first flew on 15 January ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
