Joint-stock Company
A joint-stock company is a business entity in which shares of the company's stock can be bought and sold by shareholders. Each shareholder owns company stock in proportion, evidenced by their shares (certificates of ownership). Shareholders are able to transfer their shares to others without any effects to the continued existence of the company. In modern-day corporate law, the existence of a joint-stock company is often synonymous with incorporation (possession of legal personality separate from shareholders) and limited liability (shareholders are liable for the company's debts only to the value of the money they have invested in the company). Therefore, joint-stock companies are commonly known as corporations or limited companies. Some jurisdictions still provide the possibility of registering joint-stock companies without limited liability. In the United Kingdom and in other countries that have adopted its model of company law, they are known as unlimited companies. In ...

Rostislav Alexeyev
Rostislav Evgenievich Alexeyev (russian: Ростисла́в Евге́ньевич Алексе́ев; December 18, 1916 – February 9, 1980) was a Russian Soviet Director & Chief of Design known for his pioneering work on hydrofoil ships and ground effect vehicles. Alexeyev was an accomplished designer of hydrofoil ships, such as the ''Raketa'', and became a prominent developer of ground effect vehicles, particularly the Caspian Sea Monster and the A-90 ''Orlyonok''. Biography Rostislav Evgenievich Alexeyev was born on December 18, 1916, in Novozybkov, Chernigov Governorate, Russian Empire (now in Bryansk Oblast, Russia) to an agronomist father and a teacher mother. In 1933 his family moved to Gorky, and in 1935 enrolled in a shipbuilding course at the Gorky Industrial Institute. Alexeyev graduated on October 1, 1941, after successfully defending his final thesis on hydrofoils, and was awarded the title of engineer-shipbuilder. He was sent to work at the Red Sormovo ship ...

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 ...

Lun-class Ekranoplan
The ''Lun''-class ekranoplan (also called Project 903) is the only ground effect vehicle (GEV) to ever be operationally deployed as a warship. designed by Rostislav Alexeyev in 1975 and used by the Soviet and Russian navies from 1987 until sometime in the late 1990s. It flew using lift generated by the ground effect acting on its large wings when within about above the surface of the water. Although they might look similar to traditional aircraft, ekranoplans like the ''Lun'' are not classified as aircraft, seaplanes, hovercraft, or hydrofoils. Rather, crafts like the ''Lun''-class ekranoplan are classified as maritime ships by the International Maritime Organization due to their use of the ground effect, in which the craft glides just above the surface of the water. The ground effect occurs when flying at an altitude of only a few meters above the ocean or ground; drag is greatly reduced by the proximity of the ground preventing the formation of wingtip vortices, thus ...

A-90 Orlyonok
The A-90 ''Orlyonok'' (Russian: Орлёнок, English: "Eaglet") is a Soviet ''ekranoplan'' that was designed by Rostislav Evgenievich Alexeyev of the Central Hydrofoil Design Bureau. The A-90 uses ground effect to fly a few meters above the surface. The Russians classify it as Ekranoplan Class B – it can achieve an altitude of , placing it between Class A – which is limited to ground effect, and Class C, which exploits the ground effect only during take-offs and landings and otherwise functions as a typical airplane. History The Soviet Navy command of the 1960s was very interested in a fast military transport capable of carrying a large payload. The Central Hydrofoil Design Bureau was one of the organizations working on this top-secret project, about which little was known until the fall of the Soviet Union. Chief Designer R. E. Alexeyev designed several prototypes in the 1960s. At the start of the 1970s, Alexeyev designed a medium-sized ekranoplan to be used as ...

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 ...

Aircraft Manufacturers Of Russia
An aircraft is a vehicle that is able to fly by gaining support from the air. It counters the force of gravity by using either static lift or by using the dynamic lift of an airfoil, or in a few cases the downward thrust from jet engines. Common examples of aircraft include airplanes, helicopters, airships (including blimps), gliders, paramotors, and hot air balloons. The human activity that surrounds aircraft is called ''aviation''. The science of aviation, including designing and building aircraft, is called ''aeronautics.'' Crewed aircraft are flown by an onboard pilot, but unmanned aerial vehicles may be remotely controlled or self-controlled by onboard computers. Aircraft may be classified by different criteria, such as lift type, aircraft propulsion, usage and others. History Flying model craft and stories of manned flight go back many centuries; however, the first manned ascent — and safe descent — in modern times took place by larger hot-air ba ...
