Siemens-Halske Sh 14 / SAM 314 / Bramo Sh 14 / Bramo 314 / BMW-Bramo 314 — Engine Manuals Collection

A curated archival collection of primary-source technical documents covering the Siemens-Halske Sh 14 and its successive designations — the legendary 7-cylinder air-cooled radial engine that powered the Focke-Wulf Fw 44 Stieglitz, the Bücker Bü 133 Jungmeister, and the pioneering Focke-Wulf Fw 61 helicopter, training thousands of pilots and shaping the foundations of German aviation through two decades of production.

Note on the Collection: This is the same engine under different company names over time. In 1926 the engine division became Siemens Flugmotorenwerk, marketed under the Siemens-Halske name. In the early 1930s the company became Siemens Apparate und Maschinen (SAM). In 1936 it was sold and renamed Brandenburgische Motorenwerke (Bramo). In 1939 it was acquired by BMW. Where manuals differ from the original Siemens-Halske name — SAM, Bramo, or Bramo/BMW — this is specified in the index below.

About the Siemens-Halske Sh 14

Historical Background

First introduced in 1928 by Siemens & Halske, the Sh 14 evolved from the company’s earlier radial engine development and was briefly distributed in the United States as the Ryan “Yankee 7”. Produced through approximately 1944 across the Siemens, SAM, Bramo, and BMW-Bramo eras, thousands of units were built across multiple factories. It powered primary and advanced Luftwaffe trainers including the Focke-Wulf Fw 44 Stieglitz, Bücker Bü 133 Jungmeister, and Heinkel He 72, as well as the historic Focke-Wulf Fw 61 — the world’s first practical helicopter. Post-war, it continued in European aeroclubs and surviving vintage airframes.

Technical Specifications

• Type: Air-cooled single-row radial piston engine
• Configuration: 7-cylinder
• Displacement: 7.84 L (478.4 cu in)
• Bore × Stroke: 108 mm × 120 mm (4.25 in × 4.72 in)
• Power Output: 125–160 hp
• Compression Ratio: 6.0:1
• Dry Weight: ~135 kg (298 lbs)
• Fuel: 80/87 octane aviation gasoline

Engineering Distinction

The Sh 14 features an overhead valve (OHV) valvetrain with 2 valves per cylinder, a toroidal front exhaust collector, and advanced forged aluminum components — delivering exceptional reliability for its era and earning its reputation as the backbone of interwar German flight training.

Current Status

The Sh 14 remains airworthy in restored vintage aircraft including the Bücker Bü 133 Jungmeister and Focke-Wulf Fw 44 Stieglitz, maintained under strict historical/experimental “permit to fly” regulations in Europe and FAA experimental standards in the US. No active Type Certificate holder exists; no active Service Bulletins or Airworthiness Directives apply.

This is an archival, static-copy edition fixed at its original publication date. Intended for historical reference, flight simulation, museum restoration, and educational use only. Not approved for active airworthiness maintenance under FAA 14 CFR § 43.13, EASA Part-M, or equivalent international regulations. Operators of active aircraft must use current, revision-controlled publications from the Type Certificate holder or an authorized distributor.
