Thermoplan
The Thermoplan is a given name of the prototype of Russian lenticular-shaped hybrid airship. Design features The key feature of Thermoplan is its combined structure with primary section having a torus of revolution shape (one variant was to construct this section hermetic and fill with helium instead of the shell helium section). This section supports the shell which has two sections one filled with helium and second with air that can be heated by the airship engines exhaust gas or cooled naturally. This design, based on the concept of a " rozière", greatly improves the manoeuvrability compared to an all-helium type. The disc shape is also intended to improve manoeuvrability and to help resist winds up to . Shell volume was 10660 cu. m. (376 450 cu. ft.) with its diameter of 40 m. The prototype had 2 Klimov GTD-350 engines (with 400 h.p. each), 1 Vedeneyev M14P motor (360 h.p.) and 2 electric power unit for vertical propulsion (50 h.p. each). Flight crew was 2 pilots. ...

Hybrid Airship
A hybrid airship or plimp is a powered aircraft that obtains some of its lift as a lighter-than-air (LTA) airship and some from aerodynamic lift as a heavier-than-air aerodyne. A ''dynastat'' is a hybrid airship with fixed wings and/or a lifting body and is typically intended for long-endurance flights. It requires forward flight to create the aerodynamic lift component. A ''rotastat'' is a hybrid airship with rotary wings and is typically intended for heavy lift applications. Its rotary wings can provide lift even when hovering or manoeuvring vertically, like a helicopter. No production designs have been built, but several manned and unmanned prototypes have flown. The term "hybrid airship" has also been used to describe an airship comprising a mix of rigid, semi-rigid, and non-rigid construction. Features Conventional airships have low operating costs because they need no engine power to remain airborne, but are limited in several ways, including low payload/volume rat ...

Lockheed Martin P-791
The Lockheed Martin P-791 is an experimental aerostatic and aerodynamic hybrid airship developed by Lockheed Martin. The first flight of the P-791 took place on 31 January 2006 at the company's flight test facility at United States Air Force Plant 42 in Palmdale, CA. Description The P-791 has a tri-hull shape, with disk-shaped cushions on the bottom for landing. As a hybrid airship, part of the weight of the craft and its payload are supported by aerostatic (buoyant) lift and the remainder is supported by aerodynamic lift. The combination of aerodynamic and aerostatic lift is an attempt to benefit from both the high speed of aerodynamic craft and the lifting capacity of aerostatic craft. History The P-791 was designed as part of the U.S. Army's Long Endurance Multi-intelligence Vehicle (LEMV) program, but lost the program's competition to Northrop Grumman's HAV-3 design. The P-791 was modified to be a civil cargo aircraft under the name SkyTug, with a lift capability of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EKIP
EKIP (translated from , the Russian acronym for "", which means "Ecology and Progress") is the Soviet and Russian project of a multifunctional aerodrome-free aircraft, built according to the "flying wing" scheme, with an elliptically shaped fuselage. Also known by its Russian nickname of Tarielka (, meaning "plate" or "saucer"), the EKIP can land on water or unpaved ground through the use of an air cushion instead of a wheeled undercarriage. The EKIP is a short takeoff and landing (STOL) aircraft. A special feature of the design is the presence of a special system of stabilization and reduction of drag, made in the form of a vortex control system of the boundary layer flowing around the stern surface of the device, as well as an additional flat-bed reactive system for controlling the device at low speeds and in takeoff and landing modes. The need for a stabilization system and reduction of drag is due to the fact that the body of the apparatus, made in the form of a thick wing ...

Aircraft Pilot
An aircraft pilot or aviator is a person who controls the flight of an aircraft by operating its directional flight controls. Some other aircrew members, such as navigators or flight engineers, are also considered aviators, because they are involved in operating the aircraft's navigation and engine systems. Other aircrew members, such as drone operators, flight attendants, mechanics and ground crew, are not classified as aviators. In recognition of the pilots' qualifications and responsibilities, most militaries and many airlines worldwide award aviator badges to their pilots. History The first recorded use of the term ''aviator'' (''aviateur'' in French) was in 1887, as a variation of ''aviation'', from the Latin ''avis'' (meaning ''bird''), coined in 1863 by in ''Aviation Ou Navigation Aérienne'' ("Aviation or Air Navigation"). The term ''aviatrix'' (''aviatrice'' in French), now archaic, was formerly used for a female aviator. These terms were used more in the e ...

Hybrid Vehicles
A hybrid vehicle is one that uses two or more distinct types of power, such as submarines that use diesel when surfaced and batteries when submerged. Other means to store energy include pressurized fluid in hydraulic hybrids. The basic principle with hybrid vehicles is that the different motors work better at different speeds; the electric motor is more efficient at producing torque, or turning power, and the combustion engine is better for maintaining high speed than a typical electric motor. Switching from one to the other at the proper time while speeding up yields a win-win in terms of energy efficiency, such that it translates into greater fuel efficiency. Vehicle types Two-wheeled and cycle-type vehicles Mopeds, electric bicycles, and even electric kick scooters are a simple form of a hybrid, powered by an internal combustion engine or electric motor and the rider's muscles. Early prototype motorcycles in the late 19th century used the same principle. * In a paralle ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Airships Of Russia
An airship or dirigible balloon is a type of aerostat or lighter-than-air aircraft that can navigate through the air under its own power. Aerostats gain their lift from a lifting gas that is less dense than the surrounding air. In early dirigibles, the lifting gas used was hydrogen, due to its high lifting capacity and ready availability. Helium gas has almost the same lifting capacity and is not flammable, unlike hydrogen, but is rare and relatively expensive. Significant amounts were first discovered in the United States and for a while helium was only available for airships in that country. Most airships built since the 1960s have used helium, though some have used hot air.A few airships after World War II used hydrogen. The first British airship to use helium was the ''Chitty Bang Bang'' of 1967. The envelope of an airship may form the gasbag, or it may contain a number of gas-filled cells. An airship also has engines, crew, and optionally also payload accommodation, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ulyanovsk
Ulyanovsk, known until 1924 as Simbirsk, is a city and the administrative center of Ulyanovsk Oblast, Russia, located on the Volga River east of Moscow. Population: The city, founded as Simbirsk (), was the birthplace of Vladimir Lenin (born Ulyanov), for whom it was renamed after his death in 1924; and of Alexander Kerensky, the leader of the Russian Provisional Government which Lenin overthrew during the October Revolution of 1917. It is also famous for its writers such as Ivan Goncharov, Nikolay Yazykov and Nikolay Karamzin, and for painters such as Arkady Plastov and Nikas Safronov. UNESCO has designated Ulyanovsk as a City of Literature since 2015. History Simbirsk was founded in 1648 by the boyar Bogdan Khitrovo. The fort of "Simbirsk" (alternatively "Sinbirsk") was strategically placed on a hill on the Western bank of the Volga River. The fort was meant to protect the eastern frontier of the Tsardom of Russia from the nomadic tribes and to establish a permanent r ...
