Bavar 2
The HESA Bavar 2 ( fa, باور ٢) is a ground effect vehicle unveiled in September 2010 by the IRGC Navy. It is designed to have a small radar signature, and therefore be difficult to track on radar, to be able to remain undetected while carrying out patrol missions. The vehicle can be equipped with different kinds of weapons including locally produced rockets and missiles. The design is based on the work of Alexander Lippisch and is similar in concept to the 1970s experimental RFB X-113. Analysis Because they ride on a cushion of air generated between their wings and the water's surface and don't actually fly, as such, surface-effect vehicles (SEVs) are able to sustain payloads approximately three times the weight of those carried by equivalent-sized airplanes. This fact - taken together with their small size, quick acceleration, high speed, close proximity to the water and ability to blend-in with small, stationary boats on radar while loitering - makes small SEVs like the Ba ...

Ground Effect Vehicle
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 airfoi ...

RFB X-113
The RFB X-113 Aerofoil Boat was an experimental ground effect vehicle intended to work over water. It was one of three such aircraft designed by Alexander Lippisch in the 1960s and early 1970s. The X-113 first flew in 1970; only one was built. Design and development Lippisch's development of his Aerofoil Boat, a ground effect vehicle for use over water, began whilst he was working in the aviation division of the Collins Radio Company in Cedar Rapids, Iowa, US. The first test of concept was the Collins X-112, flown in the mid-1960s. In 1967 development was continued in collaboration with Rhein-Flugzeugbau (RFB) in Germany, funded by the German government. This resulted in the X-113. The X-113 was an Ground effect vehicles#Wing configurations, inverse delta aircraft; that is, it had a wing which was triangular in plan but with a straight, unswept leading edge. Combined with strong Dihedral (aircraft)#Anhedral, anhedral, this layout produces stable flight in ground effect. Specif ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

List Of Military Equipment Manufactured In Iran
In recent years, the Iranian government states that it has self-sufficiency in essential military hardware and defense systems. Tehran established an arms development program during the Iran–Iraq War to counter the weapons embargo imposed on it by the US and its Western allies. Since 1993, Iran has manufactured its own tanks, armored personnel carriers, missiles, radars, boats, submarines, unmanned aerial vehicles, and fighter planes. History From 1925 to the Iranian Revolution in 1979, Iran used to be equipped with the very latest Western hardware. Cases exist where Iran was supplied with equipment even before it was made standard in the countries that developed it (for example the US F-14 Tomcat, or the British Chieftain Tank). Primary suppliers included the United States, Britain, France, the Federal Republic of Germany (West Germany), Italy, Israel, and the Soviet Union. The Iran–Iraq War, and post revolutionary sanctions at the time had a dramatic effect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Alexander Lippisch
Alexander Martin Lippisch (November 2, 1894 – February 11, 1976) was a German aeronautical engineer, a pioneer of aerodynamics who made important contributions to the understanding of tailless aircraft, delta wings and the ground effect, and also worked in the U.S. Within the Opel-RAK program, he was the designer of the world's first rocket-powered glider. He developed and conceptualized delta wing designs which functioned practically in supersonic delta wing fighter aircraft as well as in hang gliders. People he worked with continued the development of the delta wing and supersonic flight concepts over the 20th century. His most famous designs are the Messerschmitt Me 163 rocket-powered interceptorReitsch, H., 1955, The Sky My Kingdom, London: Biddles Limited, Guildford and King's Lynn, and the Dornier Aerodyne. Early life Lippisch was born in Munich, Kingdom of Bavaria. He later recalled that his interest in aviation began with a demonstration conducted by Orville Wrigh ...

Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, Marine radar, ships, spacecraft, guided missiles, motor vehicles, Weather radar, weather formations, and terrain-following radar, terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio spectrum, radio or microwaves domain, a transmitting antenna (radio), antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a radio receiver, receiver and Data processing system, processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the ca ...
