A fixed-wing aircraft is a 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, and ornithopters. 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.
A mountain bike (MTB) or mountain bicycle is a bicycle designed for off-road cycling. Mountain bikes share some similarities with other bicycles, but incorporate features designed to enhance durability and performance in rough terrain. These typically include a suspension fork, large knobby tires, more durable wheels, more powerful brakes, straight handlebars, lower gear-ratios for climbing steep grades and sometimes rear suspension to really smooth out the trail.
A rudder is a primary control surface used to steer a ship, boat, submarine, hovercraft, aircraft, or other conveyance that moves through a fluid medium. On an aircraft the rudder is used primarily to counter adverse yaw and p-factor and is not the primary control used to turn the airplane. A rudder operates by redirecting the fluid past the hull (watercraft) or fuselage, thus imparting a turning or yawing motion to the craft. In basic form, a rudder is a flat plane or sheet of material attached with hinges to the craft's stern, tail, or after end. Often rudders are shaped so as to minimize hydrodynamic or aerodynamic drag. On simple watercraft, a tiller—essentially, a stick or pole acting as a lever arm—may be attached to the top of the rudder to allow it to be turned by a helmsman. In larger vessels, cables, pushrods, or hydraulics may be used to link rudders to steering wheels. In typical aircraft, the rudder is operated by pedals via mechanical linkages or hydraulics.
Steering is a system of components, linkages, etc. which allows any vehicle to follow the desired course. An exception is the case of rail transport by which rail tracks combined together with railroad switches provide the steering function. The primary purpose of the steering system is to allow the driver to guide the vehicle.
The Chevrolet Impala is a full-size car built by Chevrolet for model years 1958 to 1985, 1994 to 1996, and 2000 until 2020. The Impala was Chevrolet's popular flagship passenger car and was amongst the better selling American-made automobiles in the United States.
The Chevrolet Chevelle is a mid-sized automobile which was produced by Chevrolet in three generations for the 1964 through 1978 model years. Part of the General Motors (GM) A-body platform, the Chevelle was one of Chevrolet's most successful nameplates. Body styles include coupes, sedans, convertibles and station wagons. Super Sport versions were produced through the 1973 model year, and Lagunas from 1973 through 1976. After a four-year absence, the El Camino was reintroduced as part of the new Chevelle lineup in 1964. The G-body Monte Carlo, introduced in 1970, also used a platform that was based heavily on the Chevelle platform, although it was lengthened ahead of the firewall. The Malibu, the top of the line model through 1972, completely replaced the Chevelle nameplate for the redesigned, downsized 1978 model year.
Aircraft flight control surfaces are aerodynamic devices allowing a pilot to adjust and control the aircraft's flight attitude.
Conventional landing gear, or tailwheel-type landing gear, is an aircraft undercarriage consisting of two main wheels forward of the center of gravity and a small wheel or skid to support the tail. The term taildragger is also used, although some claim it should apply only to those aircraft with a tailskid rather than a wheel.
The empennage, also known as the tail or tail assembly, is a structure at the rear of an aircraft that provides stability during flight, in a way similar to the feathers on an arrow. The term derives from the French language word empenner which means "to feather an arrow". Most aircraft feature an empennage incorporating vertical and horizontal stabilising surfaces which stabilise the flight dynamics of yaw and pitch, as well as housing control surfaces.
Laser trimming is the manufacturing process of using a laser to adjust the operating parameters of an electronic circuit.
Combat flight simulators are simulation video games used to simulate military aircraft and their operations. These are distinct from dedicated flight simulators used for professional pilot and military flight training which consist of realistic physical recreations of the actual aircraft cockpit, often with a full-motion platform.
Trim tabs are small surfaces connected to the trailing edge of a larger control surface on a boat or aircraft, used to control the trim of the controls, i.e. to counteract hydro- or aerodynamic forces and stabilise the boat or aircraft in a particular desired attitude without the need for the operator to constantly apply a control force. This is done by adjusting the angle of the tab relative to the larger surface.
The Learjet 25 is an American ten-seat, twin-engine, high-speed business jet aircraft manufactured by Learjet. It is a stretched version of the Learjet 24.
A beam axle, rigid axle or solid axle is a dependent suspension design, in which a set of wheels is connected laterally by a single beam or shaft. Beam axles were once commonly used at the rear wheels of a vehicle, but historically they have also been used as front axles in four-wheel-drive vehicles. In most automobiles, beam axles have been replaced with front and rear independent suspensions.
Self-steering gear is equipment used on sail boats to maintain a chosen course or point of sail without constant human action.
The Ford Freestyle is a crossover utility vehicle that was sold by Ford from 2005 to 2009. Largely marketed as the successor to the Ford Taurus station wagon, the Freestyle was the CUV counterpart of the Ford Five Hundred and Mercury Montego four-door sedans. Sharing the Ford D3 platform with the Five Hundred and Montego, the Freestyle was produced with both front-wheel drive and all-wheel drive configurations and six or seven-passenger seating.
3D Aerobatics or 3D flying is a form of flying using flying aircraft to perform specific aerial maneuvers. They are usually performed when the aircraft had been intentionally placed in a stalled position.
The Chevrolet Impala are full-size automobiles produced by Chevrolet for the 1965 through 1970 model years. The 1965 Impala was all new, while the 1967 and 1969 models featured new bodies on the same redesigned perimeter frame introduced on the 1965 models. All Impalas of this generation received annual facelifts as well, distinguishing each model year. Throughout the early 1960s, Chevrolet's basic body designs became increasingly subtle, while the bright trim that was part of the Impala package added more than a touch of luxury to the look. The same pattern was followed in the interiors, where the best materials and equipment Chevrolet had to offer were displayed. In short, the Impala was on its way to becoming a kind of junior-grade Cadillac, which, for both the company and its customers, was just fine.
The sixth generation of the Ford F-Series is a line of pickup trucks and medium-duty commercial trucks that were produced by Ford Motor Company from the 1973 to 1979 model years. Produced by Ford in North America, Argentina, and Australia, this is the third and final generation of trucks derived from the 1965 Ford F-Series.
The Maneuvering Characteristics Augmentation System (MCAS) is a flight control law first deployed on the Boeing KC-46 Air Force tanker, where it "moves the stabilizer in a wind-up turn". MCAS adjusts the horizontal stabilizer trim to push the nose down when the aircraft is operating in manual flight, with flaps up, at an elevated angle of attack (AoA), so the pilot will not inadvertently pull the airplane up too steeply, potentially causing a stall. Contrary to descriptions in news reports, however, Boeing claims that MCAS is not an anti-stall system.
