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 predetermined 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 regula ...

Fixed-wing Aircraft
A fixed-wing aircraft is a heavier-than-air aircraft, such as an airplane, which is capable of flight using aerodynamic lift. Fixed-wing aircraft are distinct from rotary-wing aircraft (in which a rotor mounted on a spinning shaft generates lift), and ornithopters (in which the wings oscillate to generate lift). 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 classified as fixed wing. Gliding fixed-wing aircraft, including free-flying gliders 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 ground effect vehicles. Most fixed-wing aircraft are operated by a pilot, but some are unmanned or controlled remotely or are completely autonomous (no remote pilot). History Kites Kites were used approximately 2,800 years ago ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
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. Types still in production The Dassault Falcon 7X/8X and the Dassault Falcon 900 are the only civilian trijets in production and the Chengdu J-36 is the only military trijet in production. 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-duct, S-shaped duct; this is used on the Hawker Siddeley Trident, Boeing 727, Tupolev Tu-154, Loc ...

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 rough-field 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 d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Business Jet
A business jet, private jet, or bizjet is a jet aircraft designed for transporting small groups of people, typically business executives and high-ranking coworker, associates. Business jets are generally designed for faster air travel and more personal comfort than commercial aircraft, and may be adapted for other roles, such as casualty evacuation or express package delivery, parcel deliveries, and some are used by public bodies, government officials, very important person, VIPs, or even the military. History Early developments The first small, jet-powered civilian 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 ...

Cessna Citation Longitude
The Cessna Citation Longitude is a business jet produced by Cessna, part of the Cessna Citation family. It remains the largest business jet by Cessna.

The aluminum airframe has the fuselage cross-section of the Cessna Citation Latitude, Citation Latitude, stretched by a seat row. Powered by Honeywell HTF7000 turbofans, it has a new ~28° swept wing and a T-tail for a range. Design The project is perceived as the follow-on development to the now-canceled Cessna Citation Columbus. Its fuselage cross-section ( circular section) is the same as the Cessna Citation Latitude. The aircraft has a T-tail empennage and area rule fuselage contouring. The aluminum wings incorporate moderate winglets. Construction is aluminum for both wing and fuselage. The cabin is shorter and narrower than the Columbus design. Initially, the Snecma Silvercrest engine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Regional Airliner
A regional airliner, commuter airliner or feeder liner 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. Feeder liner, 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. Examples included the De Havilland Dragon Rapide biplane and the Douglas DC-3s, in large surplus after the war, which the a ...

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 bought by Boeing in 1986, then by Bombardier in 1992, then by Longview Aviation Capital in 2019; Longview revived the De Havilland Canada brand. Powered by two Pratt & Whitney Canada PW150s, it was developed from the Dash 7 with improved cruise performance and lower operational costs, but without STOL performance. The Dash 8 was offered in four sizes: the initial Series 100 (1984–2005), the more powerful Series 200 (1995–2009) with 37–40 seats, the Series 300 (1989–2009) with 50–56 seats, and Series 400 (1999–2022) with 68–90 seats. The QSeries (Q for quiet) are post-1997 variants fitted with active noise control systems. Per a property transaction made by Bombardier before the 2019 sale to DHC, DHC had to vacate its Downsview, Toronto, manufacturing facility in August 2022, and is ...
