B.D.Maule

Belford D. Maule, or “B.D.”, as everyone knew him, was born November 4, 1911 in Old Fort, Ohio to farming parents. Not caring much for farm life, he left at the age of 15 to live in Salladasburg, PA. with an uncle and aunt who owned a garage and tea room. There he demonstrated his mechanical ability by building a tractor, and by motorizing an ice cream freezer and an ice saw, among other things.

B.D. joined the Army when he was 18 and was assigned to the 19th Airship Company at Langley Field, Virginia. While working on dirigibles, he found time to design and build his first airplane, a single seat midwing monoplane powered by a Henderson 27 HP motorcycle engine, known as the M-1. Starting with the airplane on floats, and later on wheels at the Salladasburg farm, B.D. taught himself to fly. (Regulations weren’t as strict in those days.)

Following his stint in the Army, B.D. moved back to Pennsylvania and became a family man, marrying June Aderhold in 1934. June and B.D. located in Jersey Shore, Pennsylvania and built their own home there in 1936. Note that Jersey Shore is not only June’s birthplace but is also midway between Lock Haven (Piper Aircraft) and Williamsport (Lycoming Aircraft Engines). This was an area in keeping with B.D.’s interest in aviation. B.D. went to work for Lycoming, and in 1939 designed and built “the Hummer”, a low cost mechanical starter for light aircraft. (Many airplanes did not have electrical systems back then.)
In 1940, the Maule family moved to Jackson, Michigan. Mechanical Products Company was formed to manufacture the Hummer starter (Piper and the Continental Engine Company had shown an interest). In 1941 the B.D. Maule Company was formed in Napoleon, Michigan to build a light aircraft tailwheel which B.D. had designed. The steerable, full-swiveling tailwheel, is still being manufactured by Maule, in an improved form. With the advent of World War II, the starter business waned, and tailwheels were in demand as well as subcontract work to support the war effort.

As a diversion during the latter part of the war, B.D. designed a man-powered glider with flapping wings, known as an ornithopter. He claims to be the first (and is probably the last) person to have successfully flown such a device.

In 1946, B.D. and June purchased a farm near Napoleon, Michigan. With the help of their two oldest children, they converted it to an airport. In the process, they had the dubious honor of leveling a dog race track which had been operated by Al Capone. The airport flourished, being used for flight training during the initial post-war aviation boom.

Maule Aircraft Corporation formed by B. D. Maule at Jackson, Michigan, to manufacture M-4 four-seat light aircraft; production transferred to Moultrie, Georgia, September 1968. The airplane manufacturing business that received its first FAA type certificate in 1961. Prototype flown September 8, 1961, produced as M-4 with 145 hp Continental engine, as M-4 Rocket with 210 hp Continental. M-4 Strata-Rocket with Franklin engine led to M-5-220C Lunar Rocket, flown 1 November 1971, while M-4 Rocket became M-5-210C; M-5- 235 with 235 hp Lycoming 0-540 engine also built. Current name Maule Air Inc., offering large range of four- and five-seat lightplanes for recreational and business uses in the M-7, MT-7 and MXT-7 series. Over 2,000 Maule aircraft built since 1961.

The Maules are built on the Air Force’s abandoned Spence Air Base, just east of Moultrie, Georgia. They had been building airplanes for years in Jackson, Michigan, when in 1972, a particularly severe winter convinced them to seek a warmer haven. Moultrie was looking for industry. The first production model, known as the Jetasen M-4 was delivered in April 1962. Then, as now, all Maules are constructed in Moutrie, Georgia.

Mauboussin M.40 Hémiptère

A single-seat tandem-wing research aircraft of 1936. Mauboussin argued that with the tandem wing arrangement of the wings, and the c of g is properly located, the front wing will stall first, putting the machine into a dive before it can go into a spin. If, therefore, the ailerons are transferred from the fron to the rear wing, there should be adequate control on the unstalled wing; and even if the front should have a slight tndency to spin it will be prevented by the unstalled and fully controlled rear wing from dragging the machine as a whole into a spin.

The fundamental design of the Hémiptère involves front and rear wings of different aerofoil sections, and arranged with the rear wing mounted on top of the fuselage, while the front wing is attached to the bottom of the fuselage. There is a decalage of three degrees, as the front wing is at an angle of three degrees when the wing is a 0 degree incidence. The arrangement is that of a heavy negative stagger, the distance between the front and rear wing being equal to the chord of the front wing.

M.40: c/n 01 F-AOYZ, endplate fins on high rear wing, influenced by Peyret project.

Engine: 1 x 40 hp Train 4A

Mauboussin M.200 / M.201

The Mauboussin M.200 was 1939 single-seat low-wing monoplane racer built by Fouga (F-AROP).

The M.200 set an FAI record of 255km/h over 1000 km on 7 May 1939.

The Mauboussin M.201 was a 1939 single-seat trainer with 1 x 150 hp Régnier 4Eo and 7.28 m span. It was never completed. The unfinished M.201 airframe may have been basis for the M.202

Mauboussin M.127 F-PBTB 1965

The Mauboussin M.120 was based on a 1931 collaboration between Louis Peyret and Pierre Mauboussin, the Peyret-Mauboussin PM.XII, and like it, was a low-wing cantilever monoplane of wooden construction. The undercarriage was of fixed tailskid type, and the pilot and instructor sat in tandem, open cockpits. Mauboussin built a number of prototypes himself, followed by a small series manufactured for him by Breguet in 1934.

One of first M.120s took part in the international touring aircraft contest Challenge 1932, flown by André Nicolle. It completed contest on the last 24th place, but it had the weakest engine of all participants and completing this contest was quite a success anyway.

In 1935 Maryse Hilz set a women’s altitude record of 7,388 metres on 24 September in the M.122.

In 1936, Fouga, then a builder of railway rolling stock, purchased all rights to the design as part of an effort to enter the aircraft industry, and was able to secure a contract from the Armée de l’Air to supply the type as the M.123.

The Mauboussin 123 was built 1937-1938.

M.125 F-BCEL cn.87

Production was restarted by Fouga after the war for the French flying clubs.

The M.129-28 Corsaire post-war production version was built 1947-1948. Fifty were built powered by a 60 hp Salmson 9 Adr. Twenty M.129-28 Corsaire were produced in 1948 by Fouga et Cie, the first flying on 20 March 1948.

One of first M.120s took part in the international touring aircraft contest Challenge 1932, flown by André Nicolle. It completed contest on the last 24th place, but it had the weakest engine of all participants and completing this contest was quite a success anyway. Two competed the following year, one of them with an all-women crew for probably the first time. Again, low engine power left them low in the final table.
After the Angers competition on 2 August 1933, one of the women (Hélène Boucher) set a new women’s world altitude record at 5,900 m (19,357 ft) in the M.120. In 1935 Maryse Hilsz increased it to 7,388 m (24,239 ft) on 24 September in the M.122.

Mauboussin 123

Mauboussin

Avions Mauboussin

After his separation from Peyret, Mauboussin redesignated his designs in a sequence that derives the Peyret-Mauboussin designations. The PM XI and PM XII were redesignated as M.111 and M.112 (although still reported as ‘M.11’ and ‘M.12’ in the early 1930s).

Pierre Mauboussin established design office and factory at Puteaux, Seine, France, developing Corsair light aircraft which was built as Corsair 120 and Corsair Minor.

Production aircraft designations were in a more typically French pattern. The production PM XII/M.12 became the M.120 with major developments following as M.121-M.129. Inititially, M.120 developments received suffix numbers based on their year of original (eg: the M.120/37 project of 1937 which led to the production M.123 Corsaire).

Production license for all Mauboussin aircraft acquired by Societe des Etablissements Fouga in 1936. Mauboussin 123, development of Corsair, built 1937-1938, and as M.129 1947-1948.

According to Flight (30 Sept 1943), after the Armistice the Mauboussin plant was engaged in glider production.
