The Silent Club is a single seater sailplane of Italian manufacture. It is of the FAI type DU Class glider. It is sold by Alisport ready-to-fly or kit-built as pure glider or self-launching glider. The self-launching version is fitted with a single-blade propeller belt-driven by a two-stroke engine or optionally by an electric motor.

41-485: The electric version was the first production electric-powered commercially available aircraft and appeared in 1997. It is driven by a 13 kW (17 hp) DC electric motor running on 40 kg (88 lb) of batteries that provide 1.4 kWh of energy. The highly modified version, the Alisport Silent Club-J is a self-launching aerobatic jet motor glider shown on the U.S. airshow circuit and all over

82-632: A few stalls on the ground. Air displays can be held during day or night with the latter becoming increasingly popular. Air shows often, but do not always, take place over airfields; some have been held over the grounds of stately homes or castles and over the sea at coastal resorts. The first public international airshow, at which many types of aircraft were displayed and flown, was the Grande Semaine d'Aviation de la Champagne , held Aug. 22–29, 1909 in Reims . This had been preceded by what may have been

123-518: A large loss of life, such as the 1988 Ramstein air show disaster (70 deaths) in Germany and the 2002 Sknyliv air show disaster (77 deaths) in Ukraine . Because of these accidents, the various aviation authorities around the world have set rules and guidance for those running and participating in air displays. For example, after the breakup of an aircraft at 1952 Farnborough air show (31 deaths),

164-482: A large range of speeds. Manoeuvres include aileron rolls, barrel rolls, hesitation rolls, Cuban-8s, tight turns, high-alpha flight, a high-speed pass, double Immelmans, and touch-and-gos. Tactical demos may include simulated bomb drops, sometimes with pyrotechnics on the ground for effect. Aircraft with special characteristics that give them unique capabilities will often display those in their demos; For example, Russian fighters with thrust vectoring may be used to perform

205-569: A military band playing both the French and the British national anthems to celebrate his victory. Farman had replaced the Vivinus engine of his aircraft, which was proving unreliable, with a Gnome Omega rotary engine just before the flight. Since the published rules of competition forbade any changes to the aircraft, his victory was contested by Latham and Léon Levavasseur , the designer of

246-612: A number of factors, including the weather and visibility. Most aviation authorities now publish rules and guidance on minimum display heights and criteria for differing conditions. In addition to the weather, pilots and organizers must also consider local airspace restrictions. Most exhibitors will plan "full", "rolling" and "flat" display for varying weather and airspace conditions. The types of shows vary greatly. Some are large scale military events with large flying displays and ground exhibitions while others held at small local airstrips can often feature just one or two hours of flying with just

287-499: A post office, from which 50,000 postcards were sent each day and nearly a million words dispatched by press correspondents. The spectator area was only a few hundred metres from the Laon-Reims railway line, and a temporary station was provided. A rectangular competition course of 10 km (6.2 mi), marked by four pylons was set up for the various competitions, with the strip intended for taking off and landing in front of

328-449: A public relations exercise to thank the local community, promote military careers and raise the profile of the military. Air "seasons" vary around the world. The United States enjoys a long season that generally runs from March to November, covering the spring, summer, and fall seasons. Other countries often have much shorter seasons. In Japan air shows are generally events held at Japan Air Self-Defense Force bases regularly throughout

369-517: A speed of 76.95 km/h (47.8 mph). A speed trial over five laps for dirigibles . No attempts were made until the last day, when the French Army dirigible Colonel Renard won with a time of 1 hr. 19 m. The only other competitor was a Zodiac dirigible. 38 aircraft were entered for the event, but in the end only 23 actually flew, representing nine different types. 87 flights of more than 5 km (3.1 mi) were made The type which

410-411: A time of 7 m 47.4 s. This was a distance prize offering six prizes of 50,000, 25,000, 10,000, 5,000, 5,000, and 5,000 francs. The competition for this award resulted in the world record for distance being broken three times in three days, the prize eventually being won by Henri Farman with a flight of 180 km (110 mi), flying a Farman III biplane. Farman eventually landed because

451-585: A variety of other aeronautical attractions as well, such as wing-walking, radio-controlled aircraft, water/slurry drops from firefighting aircraft, simulated helicopter rescues and sky diving . Specialist aerobatic aircraft have powerful piston engines, light weight and big control surfaces, making them capable of very high roll rates and accelerations. A skilled pilot will be able to climb vertically, perform very tight turns, tumble his aircraft end-over-end and perform manoeuvres during loops. Larger airshows can be headlined by military jet demonstration teams, such as

492-400: Is a whole raft of legislation concerning health & safety, in particular corporate manslaughter , which can involve the event organiser being charged with a criminal offence if any of the insurances and risk assessments are not fully completed well in advance of the event. Rules govern the distance from the crowds that aircraft must fly. These vary according to the rating of the pilot/crew,

533-721: The Marquis de Polignac . It was the first international public flying event and was seen both at the time and by later historians as marking the coming of age of heavier-than-air aviation. Almost all of the prominent aviators of the time took part, and the 500,000 visitors included Armand Fallières , the President of the French Republic and the British Chancellor of the Exchequer , David Lloyd George . It

574-527: The cobra maneuver or the Kulbit , while VTOL aircraft such as the Harrier may display such vertical capabilities or perform complex maneuvers with them. Some military air shows also feature demonstrations of aircraft ordnance in airstrikes and close air support , using either blanks or live munitions . Air shows may present some risk to spectators and aviators. Accidents have occurred, sometimes with

615-629: The Antoinette aircraft and engine, but the change had been officially approved before the flight, and their complaint was not successful. The Reims meeting was the public debut of the Gnome engine, and although probably unappreciated by the majority of the spectators, this was one of the most significant events to take place at the Rheims meeting. The Gnome, designed and manufactured by the Seguin brothers,

656-582: The Prix de la Vitesse held later that day, during which "the wonderful and unprecedented spectacle was witnessed of seven machines in the air at one time". Other nations were represented by the American aviator Glenn Curtiss and George Cockburn flying a French Farman III biplane representing Great Britain : promised Italian and Austrian entries did not materialise. On the Saturday of the race Curtiss made

697-463: The Sunday morning were hampered by the weather conditions, with the most successful competitor, Eugène Lefebvre flying a French-built Wright biplane , narrowly failing to complete two laps of the course: the only other pilot to make a convincing flight was Louis Blériot , and the third place was later given to Hubert Latham flying an Antoinette monoplane , on account of his performance in trials for

738-690: The United States Navy Blue Angels , United States Air Force Thunderbirds , Royal Canadian Air Force Snowbirds , Royal Air Force Red Arrows , and Swiss Air Force Patrouille Suisse , among many others. Solo military demos, also known as tactical demos, feature one aircraft. The demonstration focuses on the capabilities of modern military aircraft . The display will usually demonstrate the aircraft's very short (and often very loud) rolls, fast speeds, slow approach speeds, as well as their ability to quickly make tight turns, to climb quickly, and their ability to be precisely controlled at

779-429: The black flags signalling 'no flying' to be hoisted on occasion, all days saw some flying. The destruction by fire of Louis Blériot's aircraft on the last day was the most spectacular accident to occur during the meeting, and Blériot had been involved in another accident earlier in the week while practising for the passenger carrying event, when he had to make an emergency landing due to engine trouble, Unfortunately there

820-409: The breaking of the world record for distance, a flight of 180 km (110 mi) by Henri Farman , as well as the debut of the lightweight Gnome engine, which would achieve much acclaim. The Grand Semaine d'Aviation , held between 22 August and 29 August 1909, was sponsored by many of the leading makers of champagne including Moët et Chandon and Mumm and organised by a committee headed by

861-524: The competition stopped at half-past seven, and any distance flown after this time did not count. On landing, in the words of the correspondent from the London Times he was "seized upon by the enthusiastic crowd and carried in triumph to the buffet, where a scene of almost delirious excitement was witnessed" Although French by upbringing, Farman's father was British and he was therefore also technically British, this mixed nationality being celebrated by

902-432: The course: in the event of two contestant carrying the same number of passengers the prize going to the fastest. Won by Farman, the only pilot to carry two passengers. (Height Prize) of 10,000 francs. Won by Hubert Latham flying an Antoinette VII with an altitude of 155 m (509 ft) (Circuit Prize), of 7,000 and 3,000 francs. for the fastest single lap. Won by Louis Blériot, flying his Type XII monoplane, with

943-441: The fastest time over three laps of the circuit. The final attempts for this were held on the last day, and after Curtiss' narrow victory over Blériot spectators were expecting an exciting duel. However, Blériot had a spectacular accident: his aircraft crashed and caught fire, and was destroyed: the prize went to Curtiss. A single prize of 10,000 francs, given to the aviator who carried the greatest number of passengers over one lap of

984-583: The first ever gathering of enthusiasts, June 28 – July 19 of the same year at the airfield at La Brayelle , near Douai . Before World War II , air shows were associated with long-distance air races, often lasting many days and covering thousands of miles. While the Reno Air Races keep this tradition alive, most air shows today primarily feature a series of aerial demos of short duration. Most air shows feature warbirds , aerobatics, and demonstrations of modern military aircraft, and many air shows offer

1025-534: The first flights, first making an attempt for the Circuit Prize and lowering the record to 7 m 55.4 s. Encouraged by this, he then made his attempt for the Trophy, completing the two laps in 15 m 50.4 s. Cockburn made the next attempt, but was unable to complete one lap. Lefebvre then made the first attempt by the French team, only managing a time of 20 m 47.6 s. Latham's time

1066-439: The grandstands, opposite which was the timekeepers hut, provided with a signalling system to indicate to the spectators which event was being competed for. Flying conditions were primitive: the area over which much of the flying was to take place was farmland: some of the crops under cultivation had not been harvested and where this had been done there were haystacks : more than one flyer was to fall foul of these obstacles. This

1107-462: The ground. The largest air show measured by number of exhibitors and size of exhibit space is Le Bourget , followed by Farnborough , with the Dubai Airshow and Singapore Airshow both claiming third place. The largest air show or fly-in by number of participating aircraft is EAA AirVenture Oshkosh , with approximately 10,000 aircraft participating annually. The biggest military airshow in

1148-694: The ground. To gain such authorisations, the pilots will have to demonstrate to an examiner that they can perform to those limits without endangering themselves, ground crew or spectators. Despite display rules and guidances, accidents have continued to happen. However, air show accidents are rare and where there is proper supervision air shows have impressive safety records. Each year, organizations such as International Council of Air Shows and European Airshow Council meet and discuss various subjects including air show safety where accidents are discussed and lessons learned. Grande Semaine d%27Aviation de la Champagne The Grande Semaine d'Aviation de la Champagne

1189-531: The practicality of heavier than air aviation: it was evident that the major problem was the unreliability of the engines being used. Many previous notable aviation feats, such as Louis Blériot's recent crossing of the English Channel , had been made near the times of sunrise or sunset, when the air is often very still. In contrast, competition flying at Reims did not start until ten in the morning and ended at half past seven, and although high winds did cause

1230-469: The separation between display and spectators was increased. Air displays are often monitored by aviation authorities to ensure safe procedures. In the United Kingdom, local authorities will first need to approve any application for an event to which the public is admitted. The first priority must be to arrange insurance cover and details can be obtained from local authorities. An added complication

1271-491: The type of aircraft and the way the aircraft is being flown. For instance, slower, lighter aircraft are usually allowed closer and lower to the crowd than larger, faster types. Also, a fighter jet flying straight and level will be able to do so closer to the crowd and lower than if it were performing a roll or a loop. Pilots can get authorizations for differing types of displays (e.g., limbo flying, basic aerobatics to unlimited aerobatics) and to differing minimum base heights above

1312-546: The world by Bob Carlton. It is powered by twin AMT-USA AT-450 jet engines (200 N (45 Lbf) of thrust each) originally developed for radio-controlled aircraft . General characteristics Performance Related development Airshow An air show (or airshow , air fair , air tattoo ) is a public event where aircraft are exhibited . They often include aerobatics demonstrations, without they are called "static air shows" with aircraft parked on

1353-1143: The world is the Royal International Air Tattoo , at RAF Fairford in England . On the other hand, FIDAE in II Air Brigade of the FACH , next to the Arturo Merino Benítez International Airport in Santiago , Chile , is the largest aerospace fair in Latin America and the Southern Hemisphere . Some airshows are held as a business venture or as a trade event where aircraft, avionics and other services are promoted to potential customers. Many air shows are held in support of local, national or military charities. Military air firms often organise air shows at military airfields as

1394-405: The year. The European season usually starts in late April or Early May and is usually over by mid October. The Middle East , Australia , and New Zealand hold their events between January and March. However, for many acts, the "off-season" does not mean a period of inactivity; pilots and performers use this time for maintenance and practice. The type of displays seen at shows are constrained by

1435-465: Was 16 m 32 s. Blériot, flying last, managed a first lap time in the same time as Curtiss' second (faster) lap, but during the second round he was impeded by a squall , and his total time was 15 min 56.1 sec. Under the rules of the Trophy, Curtiss' victory meant that the next race would be held in America. Later in the day Blériot did secure one prize, that for the fastest circuit, with

1476-399: Was a troop of dragoons in the way: in swerving to avoid them, he collided with the railings separating the spectator area from the flying track. The damage was repaired overnight. At the time only one aviator had been killed in an aircraft crash, and Flight magazine could write of the "customary good luck of the aviator" when referring to aviators walking away from accidents which wrecked

1517-601: Was an 8-day aviation meeting held near Reims in France in 1909, so-named because it was sponsored by the major local champagne growers. It is celebrated as the first international public flying event, confirming the viability of heavier-than-air flight. It marked the first contest for the prestigious Gordon Bennett Trophy , sponsored by Gordon Bennett , publisher of the New York Herald , won by American Glenn Curtiss in competition with Louis Bleriot . The meeting saw

1558-495: Was best represented was the Voisin biplane , of which there were seven examples flown. This reflects Gabriel Voisin 's position as the first manufacturer to achieve widespread sales of an aircraft, but by this time his design was obsolescent, the only notable achievement being Louis Paulhan 's third place in the distance competition. Significantly, Paulhan's aircraft was fitted with a Gnome engine. The meeting effectively demonstrated

1599-541: Was both light in weight and relatively reliable, and was a major advance in aviation technology: Louis Blériot later saying "it enabled the industry to advance by leaps and bounds" Three other aircraft were flown using this engine at Reims, the others being the Farman biplanes belonging to Cockburn and Roger Sommer and the Voisin belonging to Louis Paulhan Offering four prizes of 10,000, 5,000, 3,000 and 2,000 francs, for

1640-482: Was held on the plain of Bétheny , about 5 km (3 mi) north of Reims, which later became the Reims – Champagne Air Base . A large grandstand was constructed for the event, together with a row of sheds to accommodate the aircraft. Next to the grandstand was the "Popular enclosure", complete with an enormous scoreboard. Amenities for the spectators included a restaurant that could seat 600 people, an area of specially laid lawn with bandstands and flowerbeds, and

1681-466: Was the most prestigious event of the meeting, and was a competition between national teams, sponsored by Gordon Bennett , the publisher of the New York Herald and was being held for the first time. It consisted of a time trial over two laps of the 10 km (6 mi) circuit rather than a direct race, and each nation was allowed three entrants. The qualification trials for the French team on
