Produced by the Société des Moteurs Salmson of Billancourt, France, these engines represent a pivotal chapter in aviation engineering history, and this structured collection makes their documentation accessible to historians, restorers, and vintage aviation enthusiasts worldwide.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eDefinitive Collection with Free Lifetime Updates:\u003c\/strong\u003e This is a living collection that we continuously expand and refine.

The company, formally known as the Société des Moteurs Salmson and headquartered in Billancourt, France, began producing aero engines in 1911.\u003c\/p\u003e\n\u003cp\u003eDuring the First World War, the 9Z and 9B variants — producing between 230 and 260 hp — became among the most successful stationary radial engines of the conflict, powering reconnaissance aircraft such as the Salmson 2 A.2 and various Caudron and Farman types. Approximately 3,000 units of the 9Z alone were produced in France, with licensed production also undertaken by British Salmson and Dudbridge Iron Works in the United Kingdom.\u003c\/p\u003e\n\u003cp\u003eAfter the war, Salmson pivoted decisively toward the emerging light aircraft market. The 9AD — a compact, air-cooled 9-cylinder radial producing 40–55 hp — became a defining engine of the interwar light plane movement. It powered aircraft including the Klemm L.25, Caudron C.109, Jodel D.11, and the American Eaglet, and was associated with numerous record-breaking distance and altitude flights throughout the late 1920s. Production continued until the company's liquidation in 1951, with total output across all variants reaching several thousand units.\u003c\/p\u003e\n\u003cp\u003eToday, rare examples of the Salmson 9AD survive in airworthy condition in restored Klemm L.25s and some vintage French homebuilts, while the majority of surviving engines are preserved as static displays in institutions such as the National Air and Space Museum.\u003c\/p\u003e\n\n\u003ch2\u003eManuals Included in This Collection\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eSalmson AD 9 40 PS — Aircraft Aero Operation and Maintenance Manual — Betrieb und Unterhaltung (German Language)\u003c\/li\u003e\n\u003cli\u003eSalmson M 9 — Aircraft Aero Engine Technical Manual (Italian Language)\u003c\/li\u003e\n\u003cli\u003eSalmson M 7 \/ M 9 — Aircraft Aero Engine Technical Manual (French Language)\u003c\/li\u003e\n\u003cli\u003eSalmson A9 \/ R9 — Aircraft Aero Engine Technical Manual (French Language)\u003c\/li\u003e\n\u003cli\u003eSalmson 9 Zm — Aircraft Aero Engine Description Manual (French Language)\u003c\/li\u003e\n\u003cli\u003eSalmson 9 Zm — Aircraft Aero Engine Technical Manual (French Language)\u003c\/li\u003e\n\u003cli\u003eSalmson 9 AD — Aircraft Aero Engine Technical Manual (French Language)\u003c\/li\u003e\n\u003cli\u003eSalmson 9 AB — Aircraft Engine Technical Manual (French Language)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThis collection spans the full Salmson 9-cylinder family, covering water-cooled WWI variants (9Z, 9B, M7, M9) through to the iconic air-cooled interwar types (9AD, 9AB, 9Zm, A9, R9). Documentation is presented in the original languages of publication — French, German, and Italian — reflecting the broad international reach of Salmson engines across European aviation.\u003c\/p\u003e\n\n\u003ch2\u003eEngineering Norms and Standards\u003c\/h2\u003e\n\u003cp\u003eSalmson engines were designed and manufactured to French military aviation standards of the WWI and interwar periods, including specifications issued by the Service Technique de l'Aéronautique (STAé). The Canton-Unné epicyclic gear system was a proprietary engineering solution that distinguished Salmson designs from contemporary rotary and inline engines, and the manuals in this collection document the specific tolerances, assembly procedures, and maintenance practices associated with this unique architecture. Licensed variants produced in the UK by British Salmson and Dudbridge Iron Works adhered to equivalent British Air Ministry standards of the period.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Specifications — Salmson 9AD (Representative Example)\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine type:\u003c\/strong\u003e Air-cooled radial (early models water-cooled)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e 9 cylinders, single-row radial\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDisplacement:\u003c\/strong\u003e 182 cu in (3.0 L) — 9AD; 1,112 cu in (18.2 L) — 9Z\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHorsepower range:\u003c\/strong\u003e 40 hp (9AD) to 260 hp (9Z)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBore and stroke:\u003c\/strong\u003e 2.75 × 3.375 in (9AD)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompression ratio:\u003c\/strong\u003e Approximately 5.6:1 to 6:1 depending on variant\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 154 lbs (9AD) to 473 lbs (9Z)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel type:\u003c\/strong\u003e Aviation gasoline (standard low-octane for the era)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNotable engineering feature:\u003c\/strong\u003e Canton-Unné epicyclic gear system for exceptionally smooth power delivery\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhere to Find Additional Documentation\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eHistorical Archives:\u003c\/strong\u003e The Musée de l'Air et de l'Espace (Le Bourget, France) holds archival materials related to Salmson aircraft and engines.
