Image FrontAerial.gif right frame A front aerial , performed as part of an acro dance routine A front aerial is an acrobatic move in which a person executes a complete forward revolution of the body without touching the floor. ref name Murrayp49 Front aerials are performed in various physical activities, including acro dance and gymnastics . The front aerial is known by other names, including aerial walkover and front aerial walkover . Technical The front aerial differs from a flip acrobatic front tuck in that the body assumes a form similar to that of a front walkover , with legs extended and split gymnastics split along the plane of rotation, whereas in a front tuck the knees are bent and held against the chest i.e., tucked so as to maximize rotational velocity . To compensate for lack of support from the floor, as well as the decreased rotational velocity that results from extended versus tucked legs, a front aerial performer uses the inertia of the legs to keep the body aloft until the move is completed. A front aerial can be executed either from a run or from a stationary, standing position. When starting from a standing position, a forward step is typically taken prior to the front aerial in order to develop forward momentum . In either case, at the beginning of a front aerial the performer s forward momentum is converted to the angular momentum needed for execution of the front aerial. Performance requirements Front aerials require a great degree of lower back flexibility anatomy flexibility . ref name Murrayp49 From the moment a front aerial performer leaves the floor until touching down again, the torso must remain in a stationary, inverted orientation while the lower body rotates about the torso. Adequate muscle strength is also required to execute a front aerial ... the performer aloft while the lower body completes its rotation about the torso.

Gymnasts normally perform the twisting with the legs together to obtain a faster spin and more aesthetically pleasing execution. Tricksters normally perform the twisting with the legs apart mainly for style. Many martial arts tricksters first learning this move have a tendency to begin more like a Butterfly Twist butterfly twist than an aerial. In the tricking community, this move can be done from either a running start, a small hop skip, standing, or from another trick in a combo. Variations Hyperswipe This variant of the Aerial Twist is executed the same way as an aerial twist, but normally requires extra height and faster more rotation. The defining difference is that the other leg is thrown out and is used to land on rather than the leg used to take off. Its name is derived from the fact it is a twisting move that lands on the other leg like a Butterfly kick Variants hypertwist and that the ending of it looks almost identical to a sideswipe. Aerial 720 Twist This variant is an aerial twist that rotates an additional 360 . Though in actuality, the practitioner only rotates a total of 540 . It is referred to as an aerial 720 twist because a normal twist that adds an additional 360 is referred to as a Butterfly kick Multi rotation variants 720 twist . An Aerial 720 Twist is considered more difficult because of the added rotation, extra speed and height that are required to successfully land this variant. This move is generally referred to as a Double Aerial Twist or Double A twist. Category Aerobic exercise ... more details

The field is of critical importance, and a thorough grasp of the principles of aerial rigging is essential in order to insure the safety of the artists and the audience. Aerial rigging is commonly practiced to different degrees by specialty fabricators, professional riggers, professional Acrobatics aerial artists , and amateur aerial artists. Most aerial circus equipment is built by fabricators around the world that build equipment specifically for the circus industry. Aerial artists, both professional and amateur, often become riggers out of necessity. They generally learn to rig what they need. WLA Hazard analysis Weak Link Analysis is the process of systematically analyzing aerial rigging for the weakest link or links in the system. WLA is the most common process used by aerial riggers to assess and improve rigging. However, it is not the only system used.

Straps , also known as aerial straps , are a type of aerial apparatus on which various feats of strength and flexibility may be performed, often in the context of a circus performance. It is a cotton or nylon web apparatus that looks like two suspended ribbons. Straps are available in various configurations, including those with various types of loops at the ends and those without loops. A straps act usually includes held poses and postures done on the straps, dance moves performed on the floor away from the straps, partner acrobatics done on and off the straps, as well as having the straps pulled up and let down during the act. ref http community.simplycircus.com tutorials aerialaerial arts faq.htm Aerial Arts FAQ .

Retrieved on 2012 04 15. ref The Panteleenko Brothers The discipline of aerial straps was originally a Chinese specialty where athletes would perform intensely muscular tricks up and down the straps. Many of the moves are similar to those of the Aerial Rings. The pioneers of contemporary aerial straps were identical twins Yuri and Valery Panteleenko, known as the Panteleenko Brothers. The brothers started their performance careers as part of a Russian illusionist s magic show. During a show in Rostov On Don in 1969, Vladivien Levshin, the Rubanov Company s acrobatic coach saw their athleticism and potential and began training them to perform what was to become a milestone act in the history of this apparatus. Previously, a straps routine would be performed from a static position, only moving up and down the straps. Levshin introduced swinging, circular, and two person moves. These new elements, not to mention the brothers elegance and resemblance added a new level of grace and beauty to the balletic nature of the apparatus.

Unreferenced date March 2008 Cleanup rewrite date May 2009 Aerial Observer Air Force Reconnaissance . An Aerial Observer is the functional position of gathering information visually from an airborne platform for use by military or commercial purposes. This history started when the first balloons were flown in Europe. In the early twentieth century it developed with the invention of biplanes and mono winged aircraft. During World War I and II there was a tremendous amount of intelligence gathered through these means. These crewmembers would use optical and photographic means to record their observations. In the Vietnam War , aerial observers also might be Forward Air Controller s FACs . These O 1 Bird Dog , O 2 Skymaster and OV 10 Bronco pilots would slowly fly over an area and direct bombing by radio to fast moving jet aircraft. Observer is the Royal Navy s term for its Fleet Air Arm navigator radar weapons system operators, both in two seat fixed wing combat aircraft such as the Sea Vixen and F 4 Phantom II F4K Phantom and anti submarine helicopters such as the Westland Lynx .

As aerial cranes, helicopters carry loads connected to long cables or slings in order to place heavy equipment when other methods are not available or economically feasible, or when the job must be accomplished in remote or inaccessible areas, such as the tops of tall buildings or the top of a hill or mountain, far from the nearest road. Helicopters were first used as aerial cranes in the 1950s, but it was not until the 1960s that the popularity of the use of skycranes in the construction and other industries began to catch on.

unreferenced date January 2009 A Cage aerial is a radio antenna , which consists of the top portion of a tower or mast and of several parallel wires, which are radially arranged around the lower part of the mast. one advantage of the cage aerial is that the supporting tower can be grounded, allowing it to be used for other radio services, such as a support for VHF or UHF antennas. A grounded tower also simplifies the installation of aircraft warning lamps. Cage aerials have been built in different variants for broadcasting stations in the longwave and mediumwave band. The cage is electrically one quarter of the operating wavelength long. It is connected to the mast at its upper end. This way it isolates the lower part of the mast &lambda 4 stub and makes the upper part of the mast the radiator. Very often the typical height of such an antenna is no problem as the height of the mast is selected for the TV or FM antennas on top. Example At 1000 kHz the wavelength is 300 m. Therefore the minimum length of the cage antenna is a bit more than 150 m 75 m for the radiator, 75 m for the cage and some metres to make the lower end of the cage inaccessible from the ground as the lower end of the cage carries a very high RF voltage.This antenna type is know in America as Folded unipole and extensively studied by John H. Mullaney Category Radio frequency antenna types Radio comm stub de Reusenantenne ... more details
