Historical

In 1929, the Morane Company responded to the Ed2 program (Start School Two-seater) by the Morane MS300 and MS301, these two versions differ only by their engine. They are of traditional construction: "parasol" winged monoplane reinforced by two masts and presenting a strong arrow. The train is fixed with independent wheels without carènage. The front structure of the fuselage is made of aluminum, smooth, coupled and lined, while the rear part, made of wood, is interlaced. The instructor and student sit in two separate cockpits in tandem. The MS300 is powered by a Salmson 7Ac 95hp without hood resulting in a two-bladed propeller, the MS301 receiving him Lorraine 5Pa 100ch, partially flipped: only the cylinders exceed.

The MS 300 makes its first flight in February 1930 and the MS301 in July. The latter will be presented from November 28th of the same year at the Grand Palais during the 12th Aerospace Show. Neither version will be retained: the takeoff distance of both aircraft is 150m, while the military require less than 120m ...

Morane responds by realizing the MS302 whose power is increased to 120ch thanks to the adoption of a Salmson 9Ac. The tests resume from May 1931 and the specifications for take-off are achieved. Multiple versions are available (see Description of versions below) before the birth of the version that will be produced in series: The MS315.

After the many iterations of previous versions, the MS315 finally takes the wing of the MS300, with however reduced surface fins. It is now powered by a 135hp Salmson 9Nc driving a two-bladed metal propeller, and made its first flights in late 1930. Tests being satisfactory, the state passes several orders for the new aircraft: 4 in August 1932, 30 in October 1932, 80 in 1934, 75 in 1935, 20 in 1937, 30 in 1938, ... More than 240 copies will be made before the Armistice of June 1940.

Also note the MS316 which, powered by a Lorraine 5Pc 120hp, will be sold in Peru. The 6 exported copies, will be remotorized after wear of their mechanics, by Kinner B5, American 5-cylinder engines.

The MS315, properties of the French state, will be paid into the flying schools of the Air Force from 1936 (Istres, Salon de Provence, ...), but also in civilian schools to promote the aviation of "Tourism" in France. The aircraft, with very good qualities for acrobatics, will also be used brilliantly by famous drivers such as Michel Détroyat or Pierre Fleurquin. During the German invasion, some MS315 will be captured and used by the Luftwaffe for schooling. After the war, the MS315 will continue to serve in school until the 1950s.

In 1945, after the Liberation, 110 other apparatuses will be manufactured and affected in the civil schools. Approximately 45 of them will be re-motorized by a radial-engine 220W W670K-6A starting in 1960, and will take the designation MS317. They will also receive an electric starter and a tail wheel.

In total, there will be nearly 355 models that will be built, which makes the Morane MS315 a great commercial success.

Morane MS 300
1
Prototype that, with the MS301, will be the precursor of the MS315 family. It is powered by a 95hp Salmson 7Ac and makes its first flight in February 1930. The MS300, like the MS 301, will not be able to meet the take-off demand in less than 120m and will be rejected.
Morane MS 301
1
Prototype that with the MS300, will be the precursor of the MS315 family. It is motorized by a Lorraine 5Pa of 100ch. Unlike the MS300, a hood surrounds the engine which only the cylinders exceed. He made his first flight in July 1930 and will be presented at the Salon de l'Aéronautique at the end of the year. The MS301, like the MS 300, will fail to meet the take-off demand in less than 120m and will be rejected.
Morane MS 302
1
Version, made on private funds, from the MS309. It is powered by a 120hp Salmson 9Ac more powerful than these predecessors MS 300 and 301 to improve its takeoff distance. He made his first flights in February 1931.
Morane MS 303
1
Aircraft for the promotion of this model : it is powered by a Lorraine 5Pc 120hp.
Morane MS 309
2
Prototype made on private funds with the same engine as the MS300: a Salmson 7Ac 95ch. Being very close to the MS300, it logically presents similar performances and therefore insufficient. Re-motorized by a 120ch Salmson 9Ac, it becomes the MS302
Morane MS 310
1
Version made from the MS300. Its wing area is increased: it goes from 21.6m2 to 24.6m2 by the enlargement of the wing rope. This change makes it possible to reach the requested maximum take-off distance and the state pays the manufacturer. In this configuration, it makes its first flights in July 1931, but will break during static ground resistance tests.
Morane MS 311
1
Version made from the MS301. Its wing area is increased: it goes from 21.6m2 to 24.6m2 by the enlargement of the wing rope. This change makes it possible to reach the requested maximum take-off distance and the state pays the manufacturer.
Morane MS 312
1
Aircraft that appears to be from the MS 302, which will later be put in MS315 configuration.
Morane MS 313
1
Aircraft that seems to be from the MS 303, which will later be put in MS309 configuration ...
Morane MS 315
355
Series version that takes the initial wing of the MS300 of 21.6m2, but is powered by a salmson 9Nc of 135ch more powerful. The first order for 4 copies was made in August 1932.
Morane MS 315/2
7

Two aircraft before the war and five others after the release were given a Salmson 9Nd 175hp engine.
Morane MS 316
6
Motorized version with a lorraine 5Pc of 120ch. The 6 copies made will be sold in Peru.
Morane MS 317
45
Post-war version that received a 223ch Continental W670K engine with electric starter.
