TTS-IS
TTS-IS (Russian Тяжелый транспортный самолет интегральной схемы (ТТС-ИС), heavy transport aircraft integrated circuit (HTA-IC)) is a project by TsAGI for a very large wing-in-ground-effect, lifting-body cargo aircraft with a take-off weight of 1000 tons, a payload of 500 tons, with a flight range of over 6000 km, a cruising speed of 500 km / h. Although the aircraft typically flies at above water, ice, or ground to reduce drag, it is designed to take off and land at conventional airports, unlike most ground effect vehicles but similar to the Boeing Pelican. As with the Airbus A380 and the Boeing 747-8, the aircraft is designed to land at airports that meet the Aerodrome Reference Code code 4F standard of the International Civil Aviation Organization (ICAO). It is also notable for the use of liquefied natural gas (LNG) as its aviation fuel source, and for the use of intermodal containers that are standardized in train, ship, and tru ...

Spasatel
Spasatel (russian: Спасатель "Rescuer", "Lifesaver", Project 9038) is a ground-effect vehicle, originally planned by the Soviet Ministry of Defense. The vehicle was intended to serve as the missile carrier of the project ''Lun''-class ekranoplan, but was then converted into an ambulance craft. Following the collapse of the Soviet Union in 1991, construction was halted and the vehicle was never completed. By 2018, Russia had revived the project, with plans to use it for search and rescue operations in the Arctic and Pacific, as well as cargo and troop delivery (up to 550 troops) to remote military bases. Goals A military advantage of ground-effect vehicles over ships and submarines was that they did not have draft during operation, and therefore could not be detected by sonar and could not be hit by torpedoes. Advantages over aircraft include operation at low altitude, which makes radar acquisition difficult, and a larger payload. This was particularly interestin ...

Beriev Be-2500
The Beriev Be-2500 Neptun (Russian: Бериев Бе-2500 Нептун) is a super heavy amphibious transport aircraft that, as of 2007, was in design and development by Russian design firm Beriev. The maximum takeoff weight is estimated at 2500 tons, hence its name. Design and development It has been designed to serve both as a conventional jet aircraft, flying at high altitudes transcontinentally, as well as a craft using the ground-effect at intercontinental routes across the sea. It is planned to fly via intercontinental routes, taking off from normal seaports without needing special infrastructure. The concept is thought to have some connection with the Lun-class ekranoplan of the 1970s. If it entered service, it would become the new largest airplane in the world. The concept of the aircraft was developed in the 1980s by the Beriev Design Office in collaboration with TsAGI and TsIAM. There are two versions of the design that differ in the arrangement of the gear units a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wing-in-ground-effect
A ground-effect vehicle (GEV), also called a wing-in-ground-effect (WIG), ground-effect craft, wingship, flarecraft or ekranoplan (russian: экранопла́н – "screenglider"), is a vehicle that is able to move over the surface by gaining support from the reactions of the air against the surface of the earth or water. Typically, it is designed to glide over a level surface (usually over the sea) by making use of ground effect, the aerodynamic interaction between the moving wing and the surface below. Some models can operate over any flat area such as frozen lakes or flat plains similar to a hovercraft. Design A ground-effect vehicle needs some forward velocity to produce lift dynamically, and the principal benefit of operating a wing in ground effect is to reduce its lift-dependent drag. The basic design principle is that the closer the wing operates to an external surface such as the ground, when it is said to be in ground effect, the less drag it feels. An airf ...

Twenty-foot Equivalent Units
The twenty-foot equivalent unit (abbreviated TEU or teu) is an inexact unit of cargo capacity, often used for container ships and container ports.Rowlett, 2004. It is based on the volume of a intermodal container, a standard-sized metal box which can be easily transferred between different modes of transportation, such as ships, trains, and trucks. The container is defined by its length, although the height is not standardized and ranges between and , with the most common height being . It is common to designate a container as 2 TEU, rather than 2.25 TEU. Forty-foot equivalent unit The standard intermodal container is designated as twenty feet long (6.1m) and wide. Additionally there is a standard container with the same width but a doubled length of forty feet called a 40-foot (12.2m) container, which equals one forty-foot equivalent unit (often FEU or feu) in cargo transportation (considered to be two TEU, see below). In order to allow stacking of these types a forty-fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Natural Gas
Natural gas (also called fossil gas or simply gas) is a naturally occurring mixture of gaseous hydrocarbons consisting primarily of methane in addition to various smaller amounts of other higher alkanes. Low levels of trace gases like carbon dioxide, nitrogen, hydrogen sulfide, and helium are also usually present. Natural gas is colorless and odorless, so odorizers such as mercaptan (which smells like sulfur or rotten eggs) are commonly added to natural gas supplies for safety so that leaks can be readily detected. Natural gas is a fossil fuel and non-renewable resource that is formed when layers of organic matter (primarily marine microorganisms) decompose under anaerobic conditions and are subjected to intense heat and pressure underground over millions of years. The energy that the decayed organisms originally obtained from the sun via photosynthesis is stored as chemical energy within the molecules of methane and other hydrocarbons. Natural gas can be burned fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wingtips
A wing tip (or wingtip) is the part of the wing that is most distant from the fuselage of a fixed-wing aircraft. Because the wing tip shape influences the size and drag of the wingtip vortices, tip design has produced a diversity of shapes, including: * Squared-off * Aluminium tube bow * Rounded * Hoerner style * Winglets * Drooped tips * Raked wingtips * Tip tanks * Sails * Fences * End plates Winglets have become popular additions to high speed aircraft to increase fuel efficiency by reducing drag from wingtip vortices. In lower speed aircraft, the effect of the wingtip shape is less apparent, with only a marginal performance difference between round, square, and Hoerner style tips The slowest speed aircraft, STOL aircraft, may use wingtips to shape airflow for controllability at low airspeeds. Wing tips are also an expression of aircraft design style, so their shape may be influenced by marketing considerations as well as by aerodynamic requirements. Wing tips a ...

Swept Wing
A swept wing is a wing that angles either backward or occasionally forward from its root rather than in a straight sideways direction. Swept wings have been flown since the pioneer days of aviation. Wing sweep at high speeds was first investigated in Germany as early as 1935 by Albert Betz and Adolph Busemann, finding application just before the end of the Second World War. It has the effect of delaying the shock waves and accompanying aerodynamic drag rise caused by fluid compressibility near the speed of sound, improving performance. Swept wings are therefore almost always used on jet aircraft designed to fly at these speeds. The term "swept wing" is normally used to mean "swept back", but variants include forward sweep, variable sweep wings and oblique wings in which one side sweeps forward and the other back. The delta wing is also aerodynamically a form of swept wing. Reasons for sweep There are three main reasons for sweeping a wing: 1. to arrange the center of ...

Empennage
The empennage ( or ), 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.Crane, Dale: ''Dictionary of Aeronautical Terms, third edition'', p. 194. Aviation Supplies & Academics, 1997. Aviation Publishers Co. Limited, ''From the Ground Up'', p. 10 (27th revised edition) The term derives from the French language verb ''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. In spite of effective control surfaces, many early aircraft that lacked a stabilising empennage were virtually unflyable. Even so-called "tailless aircraft" usually have a tail fin (usually a vertical stabiliser). Heavier-than-air aircraft without any kind of empennage (such as the Northrop B-2) are rare, and generally u ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pusher Configuration
In an aircraft with a pusher configuration (as opposed to a tractor configuration), the propeller(s) are mounted behind their respective engine(s). Since a pusher propeller is mounted behind the engine, the drive shaft is in compression in normal operation. Pusher configuration describes this specific ( propeller or ducted fan) thrust device attached to a craft, either aerostat (airship) or aerodyne (aircraft, WIG, paramotor, rotorcraft) or others types such as hovercraft, airboat and propeller-driven snowmobiles. "Pusher configuration" also describes the layout of a fixed-wing aircraft in which the thrust device has a pusher configuration. This kind of aircraft is commonly called a pusher. Pushers have been designed and built in many different layouts, some of them quite radical. History The rubber-powered "Planophore", designed by Alphonse Pénaud in 1871, was an early successful model aircraft with a pusher propeller. Many early aircraft (especially biplan ...
