General Characteristics
The **Macchi M.C.72** was an Italian racing floatplane designed by Mario Castoldi to compete in the Schneider Trophy competition. Though it never raced, it became legendary for setting the **absolute world speed record** for a piston-powered seaplane, a record that **still stands** today.
| Property | Value (Record-Setting Configuration) |
|---|---|
| Rolle | Experimental Racing Seaplane |
| Producent | Aeronautica Macchi |
| First Flight | juli 1931 |
| Besætning | 1 pilot |
| Konfiguration | Low-wing monoplane, twin floats |
| Maximum Take-Off Weight | Approx. 3,031 kg (6,682 lb) |
| Vingefang | 9.48 m (31 ft 1 in) |
Powerplant and Design
- Engine: One Fiat AS.6 liquid-cooled, supercharged 24-cylinder V-engine.
- Power Output: Approx. 2,126 kW (2,850 hp) to 3,100 hp. The engine was essentially two coupled V-12 units.
- Propellers: Unique contra-rotating fixed-pitch propellers, used to cancel out the massive engine torque.
- Cooling System: Featured a complex system of surface radiators integrated into the wings and floats to minimize drag.
- Construction: The forward fuselage was metal, while the aft fuselage was a monocoque wooden structure.
⚡ Performance and Record
- Absolute Speed Record: 709.209 km/h (440.681 mph), set on October 23, 1934, piloted by Warrant Officer Francesco Agello.
- Status: This remains the fastest speed ever achieved by a piston-engined seaplane.
- Armament: None, as it was a purely experimental racing aircraft.
- Historical Note: The M.C.72 suffered from multiple mechanical defects and the loss of two test pilots before successfully setting the record.
