Cruising Speed
Cruise is the phase of aircraft flight from when the aircraft levels off after a climb until it begins to descend for landing. Cruising usually comprises the majority of a flight, and may include small changes in heading (direction of flight), airspeed, and altitude. Airliner cruise Commercial or passenger aircraft are usually designed for optimum performance around their cruise speed ( VC) and cruise altitude. Factors affecting optimum cruise speed and altitude include payload, center of gravity, air temperature, and humidity. Cruise altitude is usually where the higher ground speed is balanced against the decrease in engine thrust and efficiency at higher altitudes. Common narrowbodies like the Airbus A320 and Boeing 737NG cruise at , while modern widebodies like the Airbus A350 and Boeing 787 cruise at . The typical cruising altitude for commercial airliners is . The speed which covers the greatest distance for a given amount of fuel is known as the maximum range spee ...

Electromechanics
Electromechanics combine processes and procedures drawn from electrical engineering and mechanical engineering. Electromechanics focus on the interaction of electrical and mechanical systems as a whole and how the two systems interact with each other. This process is especially prominent in systems such as those of DC or AC rotating electrical machines which can be designed and operated to generate power from a mechanical process (Electric generator, generator) or used to power a mechanical effect (Electric motor, motor). Electrical engineering in this context also encompasses electronic engineering, electronics engineering. Electromechanical devices are ones which have both electrical and mechanical processes. Strictly speaking, a manually operated switch is an electromechanical component due to the mechanical movement causing an electrical output. Though this is true, the term is usually understood to refer to devices which involve an electrical signal to create mechanical mov ...

Dowty Rotol
Dowty Propellers is a British engineering company based in Brockworth, Gloucestershire that specialises in the manufacture, repair and overhaul of propellers and propeller components for customers around the world. It is owned by GE Aerospace. History The company was formed as Rotol Airscrews in 1937 by Rolls-Royce and Bristol Engines to take over both companies' propeller development, the market being too small to support more than one company. The name is a contraction of "Rolls-Royce" and "Bristol". Rotol's propellers were always considered leading edge, its models equipping the Hawker Hurricane, Supermarine Spitfire, and many other Second World War-era aircraft. By the end of the war it had introduced the first five-bladed propeller to see widespread use, used on late-model Spitfires. In 1943 the company changed its name from Rotol Airscrews Limited to Rotol Limited, and in 1952 it acquired British Messier Limited, a specialist in landing gear and hydraulics. In 1958, ...

Composite Material
A composite or composite material (also composition material) is a material which is produced from two or more constituent materials. These constituent materials have notably dissimilar chemical or physical properties and are merged to create a material with properties unlike the individual elements. Within the finished structure, the individual elements remain separate and distinct, distinguishing composites from mixtures and solid solutions. Composite materials with more than one distinct layer are called ''composite laminates''. Typical engineered composite materials are made up of a binding agent forming the ''matrix'' and a Filler (materials), filler material (particulates or fibres) giving ''substance'', e.g.: * Concrete, reinforced concrete and masonry with cement, lime or Mortar (masonry), mortar (which is itself a composite material) as a binder * Composite wood such as glulam and plywood with wood glue as a binder * Reinforced plastics, such as fiberglass and fibre-rein ...

General Electric T700
The General Electric T700 and CT7 are a family of turboshaft and turboprop engines in the class. Design and development In 1967, General Electric began work on a new turboshaft engine demonstrator designated the "GE12" in response to US Army interest in a next-generation utility helicopter. The GE12 was designed and conceived by GE's Art Adamson and Art Adinolfi. In 1967, both GE and Pratt & Whitney were awarded contracts to work parallel with each other to design, fabricate, and test the technology. The Army effort led, in the 1970s, to development of the Sikorsky S-70 Black Hawk, powered by twin GE "T700" turboshafts, the production descendant of the GE12. The T700 was initially bench-tested in 1973, passed military qualification in 1976, and went into production in 1978. The initial "T700-GE-700" is an ungeared free-turbine turboshaft, with a five-stage axial / one-stage centrifugal mixed-flow compressor, featuring one-piece "blisk" axial stages, with the inlet guide vanes a ...

Point-to-point Transit
Point-to-point transit is a transportation system in which a plane, bus, or train travels directly to a destination, rather than going through a central Transport hub, hub. This differs from the spoke-hub distribution paradigm in which the transportation goes to a central location where passengers change to another train, bus, or plane to reach their destination. Use in airlines The point-to-point model is used widely by low-cost carriers, including Allegiant Air and Southwest Airlines in the U.S., and European carriers such as Ryanair, easyJet and Wizzair, along with some low-cost carriers in Asia like AirAsia, Lion Air and VietJet Air, for example. Many such airlines sell each flight leg independently and have no concept of round-trip ticketing or connecting flights so baggage must be collected and rechecked even to transfer between flights booked at the same time on the same airline. Although there are many point-to-point airlines, most have at least a "homebase" airport where ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
