Template:Infobox aircraft The Macchi M.20 was a single-engine biplane designed as a trainer aircraft and manufactured by the Italian aviation firm Aeronautica Macchi around the late 1910s to early 1920s.
Produced in limited quantities and aimed at the civilian aviation sector, the M.20 was developed alongside the Macchi M.16, a single-seat sports aircraft for private pilots.[1]
Development history
Following the conclusion of World War I in November 1918, when military orders ceased, the technical department at Macchi, led by aeronautical engineer Alessandro Tonini, initiated the design of two lightweight aircraft tailored for civilian use. These models were the Macchi M.16, aimed at leisure flying, and the M.20, which featured dual controls to facilitate pilot instruction. Both the M.16 and M.20 shared a common design philosophy and configuration as single-engine biplanes equipped with fixed landing gear.[1]
Technical description
The M.20 represented a typical design for its era: a single-engine, two-seat biplane featuring fixed landing gear. Its landing gear had a narrow track and incorporated internal shock absorbers. Constructed with a deep fuselage composed of a wooden lattice framework, the M.20 avoided the use of tensioners and metal cables, thereby eliminating the need for tie rod adjustments. The aircraft was equipped with disengageable dual controls.[2] Although it had a low empty weight—variously reported between 250 and 340 kilograms (551 and 750 lb)—its modest 34-kilowatt (45-horsepower) engine limited its overall performance.[1][2]
In 1925, following the appointment of Mario Castoldi as Macchi’s technical director, the M.20 underwent modifications that included a thicker airfoil and the addition of ailerons on the upper wings.[2] These enhancements were designed to be retrofitted to previously built M.20 models.[2]
Additionally, one M.20 was tested with floats to operate as a floatplane.[2]
Operational use
The Macchi M.20 took to the skies shortly after World War I concluded. Entering a civilian market saturated with surplus military aircraft, the M.20 achieved only limited commercial traction and was produced in small quantities. It found use both among private owners and flying clubs, remaining operational until approximately Italy's entry into World War II in 1940.[2]
On 12 October 1924, an M.20 flown by Giovanni De Briganti secured victory in the Coppa Italia ("Italian Cup") race, which took place on the circuit connecting Ciampino, Montecelio, and Centocelle.[2]
Surviving example
As of 2012, an M.20 displayed at the Gianni Caproni Museum of Aeronautics in Trento, Italy, is recognized as the oldest surviving Macchi-designed aircraft within Italy.[2] Likely constructed between 1920 and 1925,[2] this aircraft was later updated with the thicker wings and ailerons introduced in 1925.[2] In 1929, it was acquired by Società Anonima Aerocentro Emiliano, fitted with a Salmson 9 AD engine, and registered as I-AABO in March 1930.[2] The Aero Club of Rimini purchased it in September 1933; it was subsequently written off following an accident.[2] Later owned by Milanese aeronautical engineer and manufacturer Piero Magni, it underwent further alterations in 1939 including rounded, elongated wing tips, enlarged cockpits, and modified fletchings; however, this version did not receive airworthiness certification.[2]
During the 1950s, the aircraft’s fuselage and wings were acquired from aviation pioneer and aeronautical engineer Pier Carlo Bergonzi by the Caproni brothers,[2] eventually becoming part of the Gianni Caproni Museum of Aeronautics collection by the 1970s.Template:Fix/category[citation needed] Restoration work was carried out by Masterfly between 1988 and 1990.[2] The aircraft is currently painted to represent an unregistered M.20 racer from around 1924–1925.[2]
