Curtiss-Wright SNC-1 Falcon (Model 22B) — Flight & Technical Documentation Collection

CW-22B-NEI · SNC-1 · Wright R-975 Whirlwind

Online Aviation Library presents a structured archival collection of surviving original flight and technical documentation for the Curtiss-Wright Model 22B and its U.S. Navy designation, the SNC-1 Falcon. These are primary-source documents: the actual publications issued to aircrew and ground engineers during active service — released by the Curtiss-Wright Corporation Airplane Division, St. Louis Plant, and the Bureau of Aeronautics, Navy Department.

The SNC-1 was an all-metal, cantilever low-wing monoplane derived from the CW-19 light fighter, engineered at the Curtiss-Wright St. Louis Airplane Division as an advanced transition trainer. Its wide-vision tandem canopy, fighter-like control response, and retractable undercarriage made it a demanding and effective bridge between primary trainers and frontline combat aircraft.

➡️ Aerodynamic Design & Engineering Notes

Low-Wing Monoplane Profile: All-metal, cantilever low-wing monoplane derived from the CW-19 light fighter, engineered by the Curtiss-Wright St. Louis Airplane Division.

Retractable Undercarriage: Backward-retracting main landing gear identical in concept to the CW-21 Demon fighter design — wheels partially exposed in under-wing fairings, reducing drag while providing aerodynamic backup for belly-landings.

Wing Loading: Total wing area of 173.70 sq ft (16.14 m²), balancing high-speed advanced transition training with stable, low-speed runway approaches.

💡 Engine Technical Notes — Wright R-975 Whirlwind

Power Plant: One Wright Whirlwind R-975-28, 9-cylinder air-cooled radial piston engine rated at 420–450 hp (313–336 kW), driving a two-blade variable-pitch metal propeller. Positioned as a lower-power, more fuel-efficient option for intermediate aviator transition compared to the heavier SNJ (North American T-6 Texan) with its Pratt & Whitney R-1340.

🔎 Handling & Stability

Tandem Configuration: Evaluated under U.S. Navy criteria for transitional training. The wide glass canopy offered excellent visibility for both instructor and student, addressing limitations common in older biplane trainers.

Control Response: Built to mirror the rapid control surfaces of a frontline fighter — intentionally teaching stall recovery, rudder control against engine torque, and complex instrument flight conditions.

📊 Performance Reference Data

⚠️ Regulatory Notice: Under FAA 14 CFR § 43.13 and EASA Part-M, any mechanic performing maintenance on an active aircraft must use current, manufacturer-approved revision-controlled data. This archival document does not satisfy that requirement.

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.
