Aermacchi was an Italian aircraft manufacturer . Formerly known as Aeronautica Macchi , the company was founded in 1912 by Giulio Macchi at Varese in north-western Lombardy as Nieuport-Macchi , to build Nieuport monoplanes under licence for the Italian military. With a factory located on the shores of Lake Varese , the firm originally manufactured a series of Nieuport designs, as well as seaplanes .

Since the mid-1990s, Alenia Aermacchi has participated in programs for the supply of engine nacelles for civil aircraft. It produces cold parts for engine nacelles: inlets, fan cowls and EBU, the systems-to-engine interface. In 1999, the company established
403-413: The 'Convertible', with the majority of working parts semi-enclosed, an under-saddle engine and foot boards, a conventional motorcycle fuel tank position and 17 in (430 mm) wheels. It was succeeded in 1953 by the 'Zeffiro' which was offered with a 125 cc or 150 cc two-stroke engine ; these later models had upgraded suspension but remained similar in appearance. In 1955, they produced
434-466: The 125 cc Monsone, followed by the 150 cc Corsaro, both of which had pivoted fork rear suspension and telescopic front forks . They were two-strokes like the early models and ran a 4-speed gearbox. In 1956 they produced their first over head valve four-stroke engine on the Chimera fitted horizontally, a layout which would become a standard for the marque. Similar to their first offering,
465-423: The 9.26m (30ft 4.5in) of the racers- and was powered by a 447-kilowatt (600- horsepower ) Fiat AS.2 liquid-cooled V12 engine , while the racing version had a 597-kilowatt (800-horsepower) Fiat AS.2. Macchi built two trainers, three racers, and one non-flying static-test airframe . The first M.39, a trainer with serial number MM.72, was built in only a few months. It was soon followed by the second trainer (MM.73),
496-538: The Chimera kept many enclosed working parts. In 1957 they released a series of sport models, powered by a single cylinder ohv engine in 175 cc or 250 cc displacements . Aermacchi continued with scooter production, but sales were poor and they were unable to compete in the market amongst the well established Vespas and Lambrettas , and concentrated solely on the production of motorcycles. In 1960, US business Harley-Davidson motorcycles purchased 50% of Aermacchi's motorcycle division. The Italian branch of
527-502: The aircraft was performed at the company's factory in Varese , north-western Lombardy . It was a single-seat twin-float seaplane of mixed (metal and wooden) construction. The pilot sat in an open cockpit above the trailing edge of the wing; the cockpit ' s windscreen was profiled into the fuselage decking to reduce drag . This fuselage was streamlined and intentionally avoided angularity. The horizontal empennage consisted of
558-582: The brand was named 'Aermacchi-Harley-Davidson' and the first bike was a variation of the 'Ala Verde' suitably modified for the American market. This was also the year that the Chimera ceased production. The remaining motorcycle holdings were sold in 1974 to AMF-Harley-Davidson , with motorcycles continuing to be made at Varese. The business was sold to Cagiva in 1978. After the Harley Davidson investment, Aermacchi branched out into racing with
589-489: The company began producing motorcycles as a way to fill the post-war need for cheap, efficient transportation. The company later specialised in civil and military pilot training aircraft. In July 2003, Aermacchi was integrated into the Finmeccanica Group (now Leonardo) as Alenia Aermacchi , which increased its shareholding to 99%. Since the beginning, the design and production of military trainers have been
620-407: The company's preceding racing flying boat, the Macchi M.33 , was present in its design. It had been determined that the prior aircraft's basic configuration, which was built around a central hull, while affording great stability upon the water, would unavoidably present a great obstacle to penetration and thus was substituted for a pair of braced floats that formed a rigid support. Construction of

#1732766061904682-475: The course circuit required left turns, the left wing of the aircraft had a slightly greater span than the right wing, which permitted the aircraft to make tighter left-hand turns. To counteract propeller torque reaction, the floats had unequal buoyancy . Furthermore, fuel was stored within these floats. Macchi produced two versions of the M.39, a trainer version and a racer. The trainer version had an increased wingspan of 10.23 metres (33ft 7in) -compared to
713-538: The era. Two versions of the M.39, a trainer version and a racer, were produced. On 6 July 1926, the first aircraft, the trainer model MM.72, performed the type's maiden flight . On 13 November 1926, three M.39s participated in the 1926 Schneider Trophy contest, held at Hampton Roads , Virginia , in the United States; one aircraft, MM.76, piloted by Mario de Bernardi , took first place with an average speed of 396.698 kilometres per hour (246.497 mph), setting

775-496: The three M.39 racers took part in the 1926 Schneider Trophy contest at Hampton Roads , Virginia , in the United States. MM.75 suffered a burst pipe and had to leave the race early, but MM.76, piloted by Mario de Bernardi , took first place with an average speed of 396.698 kilometres per hour (246.497 mph), setting a new world speed record for seaplanes. MM.74, flown by Adriano Bacula , came in third place. Four days later, on 17 November 1926, de Bernardi used MM.76 to achieve
806-474: The three racers (MM.74, MM.75, and MM.76), and the static-test airframe. On 6 July 1926, the trainer MM.72 performed its maiden flight , becoming the first M.39 to fly. On 16 September 1926, the Italian Schneider team captain stalled one of the trainers over Lake Varese and was killed in the resulting crash into the lake itself. Development of the M.39 proceeded undaunted. On 13 November 1926,
837-456: The water in the cylinder jackets and tubing, the residual oil, the starter apparatus and the fuel pump , was exceptionally low (467 grams (1.03 lb.) per hp); it was reportedly lighter that any other powerplant in its power range in production with any other manufacturer in the world at that time. The M.39 was specifically built to compete for the Schneider Trophy; accordingly, its design had specialised features to aid it in this exact purpose. As
868-440: The wing's upper surfaces functioned as low drag surface radiators . The adoption of such a radiator arrangement, which avoided the drag that would have otherwise been generated through the use of traditional honeycomb or fin-type radiators, was considered to be a key innovation of the aircraft. The oil radiator was incorporated in the bottom of the fuselage in a relatively exposed position to achieve effective cooling. The M.39
899-466: Was a racing seaplane designed and built by the Italian aircraft manufacturer Aeronautica Macchi . The type is most remembered for its settings of multiple world speed records during the mid 1920s, as well as for winning the Schneider Trophy , for which the M.39 had been specifically developed. Designed by Mario Castoldi and constructed in Varese , north-western Lombardy , the M.39 was
930-424: Was powered by a Fiat AS.2 water-cooled V-12 piston engine, which was directly drove the propeller . This engine, which was installed within the aircraft's nose, was equipped with three double carburetors , one for every four cylinders, that were specifically designed as to enable them to operate normally at practically any orientation of the aircraft. The power-to-weight ratio achieved by this engine, inclusive of
961-485: Was very fast, with 46hp at 11,000rpm, and weighed only 250lbs. After Harley-Davidson acquired 100% of Aermacchi in 1972, they funded further racing development at the Aermacchi factory, and the racers were branded with Harley-Davidson on their fuel tanks. These two-stroke twins provided Harley-Davidson with their only Grand Prix wins, and four World Championships : 250cc World Championship in 1974 , '75 , and '76 , and
