Fiat C.R.30 — Primary-Source Documentation Collection

The Fiat C.R.30, designed by Celestino Rosatelli for Fiat Aviazione in 1932, served as the definitive technical and structural blueprint for Italy’s most celebrated interwar biplane fighters. Its rigid Warren Truss interplane bracing, streamlined nose cowl, and high-compression Fiat A.30 V-12 established the engineering language that would define the C.R.32 and C.R.42 lineage. This collection assembles 3 primary-source documents covering the airframe variants and the photographic archive.

Aerodynamic Reports

• Wing Layout: Rigid sesquiplane design — upper wing area significantly larger than the lower wing.
• Interplane Bracing: Rigid Warren Truss “W” configuration struts eliminating traditional drag-heavy bracing wires.
• Fuselage Profile: Aerodynamically streamlined nose cowl tapering into a fabric-skinned rear section to optimize airflow.
• Cooling Drag: Frontal radiator integration engineered to minimize frontal surface area.

Engine Technical Notes — Fiat A.30 R.A.

• Type: Water-cooled 60° upright V-12 piston engine.
• Normal Output: 600 hp (447 kW) at 2,000 rpm.
• Peak Output: 800 hp at 2,900 rpm during takeoff.
• Compression Ratio: 8.1:1 — normal aspiration, non-supercharged.
• Propeller: Fiat metal two-blade, 2.82 m diameter, variable-pitch adjustable on ground only.

Handling & Stability Studies

• Maneuverability: Highly responsive elevator and aileron authority optimized for closed-circuit dogfighting.
• Structural Rigidity: Steel-reinforced duralumin framework providing high G-load tolerance during violent aerobatics.
• Landing Gear: Fixed main gear with aerodynamic spats; castering self-centering tailwheel.
• Visibility: Cockpit staggered rearward to offset upper-wing blind spots.

Performance Data

Engineering Bulletins & Variants

• CR.30 B / Bis: Engineering directives detail the conversion of standard single-seaters into two-seat dual-control liaison/trainer aircraft (C.R.30 Biposto).
• CR.30 Idro: Technical modification bulletin covering integration of twin duralumin floats for marine operations.
• C.A.N.S.A. Production: The CR.30 B variant was produced under licence by C.A.N.S.A. (Cameri, Novara) with the uprated Fiat A.30 R.A. bis engine.
