Aerospace Engineering
Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. It has two major and overlapping branches: aeronautical engineering and astronautical engineering. Avionics engineering is similar, but deals with the electronics side of aerospace engineering. "Aeronautical engineering" was the original term for the field. As flight technology advanced to include vehicles operating in outer space, the broader term "aerospace engineering" has come into use. Aerospace engineering, particularly the astronautics branch, is often colloquially referred to as "rocket science". Overview Flight vehicles are subjected to demanding conditions such as those caused by changes in atmospheric pressure and temperature, with structural loads applied upon vehicle components. Consequently, they are usually the products of various technological and engineering disciplines including aerodynamics, air propulsion, avionics, materials science, st ...

Wind Tunnels
A wind tunnel is "an apparatus for producing a controlled stream of air for conducting aerodynamic experiments". The experiment is conducted in the test section of the wind tunnel and a complete tunnel configuration includes air ducting to and from the test section and a device for keeping the air in motion, such as a fan. Wind tunnel uses include assessing the effects of air on an aircraft in flight or a ground vehicle moving on land, and measuring the effect of wind on buildings and bridges. Wind tunnel test sections range in size from less than a foot across, to over , and with air speeds from a light breeze to hypersonic. The earliest wind tunnels were invented towards the end of the 19th century, in the early days of aeronautical research, as part of the effort to develop heavier-than-air flying machines. The wind tunnel reversed the usual situation. Instead of the air standing still and an aircraft moving, an object would be held still and the air moved around it. In this ...

FLUENT
Fluency (also called volubility and eloquency) refers to continuity, smoothness, rate, and effort in speech production. It is also used to characterize language production, language ability or language proficiency. In speech language pathology it means the flow with which sounds, syllables, words and phrases are joined when speaking quickly, where fluency disorder has been used as a collective term for cluttering and stuttering. Definition Fluency is a term concerning language production on the one hand, which is used in language ability or language proficiency It is also used to characterize speech production on the other hand with some overlap. In speech language pathology it means the smoothness or flow with which sounds, syllables, words and phrases are joined when speaking quickly. It refers to "continuity, smoothness, rate, and effort in speech production". The term fluency disorder has been used as a collective term for cluttering and stuttering since at least 1993. ...

Computational Fluid Dynamics
Computational fluid dynamics (CFD) is a branch of fluid mechanics that uses numerical analysis and data structures to analyze and solve problems that involve fluid dynamics, fluid flows. Computers are used to perform the calculations required to simulate the free-stream flow of the fluid, and the interaction of the fluid (liquids and gases) with surfaces defined by Boundary value problem#Boundary value conditions, boundary conditions. With high-speed supercomputers, better solutions can be achieved, and are often required to solve the largest and most complex problems. Ongoing research yields software that improves the accuracy and speed of complex simulation scenarios such as transonic or turbulence, turbulent flows. Initial validation of such software is typically performed using experimental apparatus such as wind tunnels. In addition, previously performed Closed-form solution, analytical or Empirical research, empirical analysis of a particular problem can be used for compa ...

GE Aviation
General Electric Company, doing business as GE Aerospace, is an American aircraft engine supplier that is headquartered in Evendale, Ohio, outside Cincinnati. It is the legal successor to the original General Electric Company founded in 1892, which split into three separate companies between November 2021 and April 2024, adopting the trade name GE Aerospace after divesting its GE HealthCare, healthcare and GE Vernova, energy divisions. GE Aerospace both manufactures engines under its name and partners with other manufacturers to produce engines. CFM International, the world's leading supplier of aircraft engines and GE's most successful partnership, is a 50/50 joint venture with the French company Safran Aircraft Engines. As of 2020, CFM International holds 39% of the world's commercial aircraft engine market share (while GE Aerospace itself holds a further 14%).

GE90
The General Electric GE90 is a family of high-bypass turbofan aircraft engines built by GE Aerospace for the Boeing 777, with thrust ratings from . It entered service with British Airways in November 1995. It is one of three engines for the 777-200 and -200ER, and the exclusive engine of the -200LR, -300ER, and 777F. It was the largest jet engine, until being surpassed in January 2020 by its successor, the GE9X, which has a larger fan diameter by . However, the GE90-115B, the most recent variant of the GE90, is rated for a higher thrust (115,000 lbs) than the GE9X. Background In the early 1980s, GE began to develop an unducted fan (UDF) engine, which was thought to be a more fuel-efficient option to propel short-haul airliners, a compelling proposition after the 1979 oil crisis. NASA gave GE a grant in February 1984 to continue its research, eventually building the experimental GE36. One of the major innovations for the engine were its carbon fiber composite fan blades, whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
