JT15D
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 ...

Cessna Citation II
The Cessna Citation II are light corporate jets built by Cessna as part of the Citation family. Stretched from the Citation I, the Model 550 was announced in September 1976, first flew on January 31, 1977, and was certified in March 1978. The II/SP is a single pilot version, the improved S/II first flew on February 14, 1984 and the Citation Bravo, a stretched S/II with new avionics and more powerful P&WC PW530A turbofans, first flew on April 25, 1995. The United States Navy adopted a version of the S/II as the T-47A. Production ceased in 2006 after of all variants were delivered. Design and development The Citation II (Model 550) was developed to provide the samw docile low-speed handling and good short-field performance as the preceding Citation I while addressing a primary criticism of that aircraft — its relatively slow cruise speed of around at altitude. The II stretches the Citation I fuselage by 1.14m (3 ft 9in), increasing seating capacity to ten (two pilo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 ...

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] |
Cessna Citation I
The Cessna 500 Citation I is a small business jet produced by Cessna, the basis of the Citation family. The Fanjet 500 prototype was announced in October 1968, first flew on September 15, 1969, and was certified as the 500 Citation on September 9, 1971. It was upgraded in 1976 as the ''Citation I'', and the 501 Citation I/SP single-pilot variant was introduced in 1977. Production ended in 1985 with 689 of all variants produced. The straight wing jet is powered by JT15D turbofans. The aircraft was developed into the Citation II. Development In the early 1960s, the three major American general aviation aircraft manufacturers—Beechcraft, Cessna and Piper–faced a competitive challenge in the form of two newly-developed light business jets, the Learjet 23 and the Aero Commander 1121 Jet Commander, which were much less expensive to buy and operate than previous business jets such as the North American Sabreliner and Hawker Siddeley HS.125.

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] |
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.
