Stick Pusher
A stick pusher is a device installed in some fixed-wing aircraft to prevent the aircraft from entering an aerodynamic stall. Some large fixed-wing aircraft display poor post-stall handling characteristics or are vulnerable to deep stall. To prevent such an aircraft approaching the stall the aircraft designer may install a hydraulic or electro-mechanical device that pushes forward on the elevator control system whenever the aircraft's angle of attack reaches the pre-determined value, and then ceases to push when the angle of attack falls sufficiently. A system for this purpose is known as a stick pusher. The safety requirements applicable to fixed-wing aircraft in the transport category, and also to many military aircraft, are relatively demanding in the area of pre-stall handling qualities and stall recovery. Some of these aircraft are unable to comply with these safety requirements relying solely on the natural aerodynamic qualities of the aircraft. In order to comply with regulat ...

Fixed-wing Aircraft
A fixed-wing aircraft is a heavier-than-air flying machine, such as an airplane, which is capable of flight using wings that generate lift caused by the aircraft's forward airspeed and the shape of the wings. Fixed-wing aircraft are distinct from rotary-wing aircraft (in which the wings form a rotor mounted on a spinning shaft or "mast"), and ornithopters (in which the wings flap in a manner similar to that of a bird). The wings of a fixed-wing aircraft are not necessarily rigid; kites, hang gliders, variable-sweep wing aircraft and airplanes that use wing morphing are all examples of fixed-wing aircraft. Gliding fixed-wing aircraft, including free-flying gliders of various kinds and tethered kites, can use moving air to gain altitude. Powered fixed-wing aircraft (airplanes) that gain forward thrust from an engine include powered paragliders, powered hang gliders and some ground effect vehicles. Most fixed-wing aircraft are flown by a pilot on board the craft, but some ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trijet
A trijet is a jet aircraft powered by three jet engines. In general, passenger airline trijets are considered to be second-generation jet airliners, due to their innovative engine locations, in addition to the advancement of turbofan technology. Trijets are more efficient than quadjets, but not as efficient as twinjets, which replaced trijets as larger and more reliable turbofan engines became available. Design One consideration with trijets is positioning the central engine. This is usually accomplished by placing the engine along the centerline, but still poses difficulties. The most common configuration is having the central engine located in the rear fuselage and supplied with air by an S-shaped duct; this is used on the Hawker Siddeley Trident, Boeing 727, Tupolev Tu-154, Lockheed L-1011 TriStar, and, more recently, the Dassault Falcon 7X. The S-duct has low drag, and since the third engine is mounted closer to the centerline, the aircraft will normally be easy to hand ...

Pilatus PC-24
The Pilatus PC-24 is a light business jet produced by Pilatus Aircraft of Switzerland. Following the success of the PC-12 single engine turboprop, work on the twin engine jet began in 2007 for greater range and speed, keeping the rugged airfield capability. The aircraft was introduced on 21 May 2013 and rolled out on 1 August 2014, with the maiden flight on 11 May 2015. The PC-24 received EASA and FAA type certification on 7 December 2017 and the first customer delivery was on 7 February 2018. Powered by two Williams FJ44 turbofans, it competes with the Embraer Phenom 300 and the Cessna Citation CJ4. Development During the 1990s, Pilatus Aircraft had brought to market the Pilatus PC-12, a single-engine turboprop-powered business aircraft. As the PC-12 quickly proved to be a commercial success, Pilatus sought to follow up with a complementary aircraft and began gathering feedback from customers of the type. In response to this request, several customers reportedly expressed a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Business Jet
A business jet, private jet, or bizjet is a jet aircraft designed for transporting small groups of people. Business jets may be adapted for other roles, such as the evacuation of casualties or express parcel deliveries, and some are used by public bodies, government officials or the armed forces. History Early developments The first small jet-powered civil aircraft was the Morane-Saulnier MS.760 Paris, developed privately in the early 1950s from the Morane-Saulnier MS.755 Fleuret, MS.755 Fleuret two-seat jet trainer. First flown in 1954, the MS.760 Paris differs from subsequent business jets in having only four seats arranged in two rows without a center aisle, similar to a light aircraft, under a large sliding canopy (aircraft), canopy similar to that of a fighter aircraft, fighter. A U.S. type certificate was awarded in July 1958, but commercial sales were limited, with most examples going to the military; an improved civil version similar to a modern very light jet, with a ...

Regional Airliner
A regional airliner or a feederliner is a small airliner that is designed to fly up to 100 passengers on short-haul flights, usually feeding larger carriers' airline hubs from small markets. This class of airliners is typically flown by the regional airlines that are either contracted by or subsidiaries of the larger airlines. Regional airliners are used for short trips between smaller towns or from a larger city to a smaller city. Feederliner, commuter, and local service are all alternative terms for the same class of flight operations. History To keep short routes economical, airlines preferred using second hand aircraft than costlier new aircraft. Older aircraft were put into short haul service as they were replaced by new longer-range designs. Post-war era Propeller aircraft of larger airlines were transferred to smaller airlines: even the De Havilland Dragon Rapide biplane, or the Douglas DC-3s, in large surplus after the war, which the Aircraft manufacturers wanted t ...

De Havilland Canada Dash 8
The De Havilland Canada DHC-8, commonly known as the Dash 8, is a series of turboprop-powered regional airliners, introduced by de Havilland Canada (DHC) in 1984. DHC was later bought by Boeing in 1988, then by Bombardier in 1992; then by Longview Aviation Capital in 2019, reviving the De Havilland Canada brand. Powered by two Pratt & Whitney Canada PW100s, it was developed from the Dash 7 with improved cruise performance and lower operational costs, but without STOL performance. Three sizes were offered: initially the 37–40 seat -100 until 2005 and the more powerful -200 from 1995, the stretched 50–56 seats -300 from 1989, both until 2009, and the 68–90 seats -400 from 1999, still in production. The QSeries are post-1997 variants fitted with active noise control systems. Development Initial development In the 1970s, de Havilland Canada had invested heavily in its Dash 7 project, concentrating on STOL and short-field performance, the company's traditional ...
