The I.Ae. 30 "Ñancú" was an Argentine twin-engine piston fighter crafted by the Instituto Aerotécnico during the late 1940s. While it bore resemblance to the de Havilland Hornet, its construction utilized metal rather than wood. Only a single prototype was completed before the initiative was discontinued in favor of the jet-powered FMA I.Ae. 27 Pulqui I.
Design and development
Bearing the name of a Patagonian eagle, the I.Ae. 30 was developed under the guidance of Italian engineer Cesare Pallavicino, who arrived in Argentina in 1946. He headed a team tasked with creating a high-speed escort fighter to accompany Avro Lincoln bombers operated by the Argentine Air Force.
The aircraft incorporated a metallic airframe powered by two Rolls-Royce Merlin 604 engines, each producing 1,800 hp at 3,000 RPM, paired with four-blade propellers. Initial armament plans consisted of six 20 mm Oerlikon automatic cannons mounted in the nose, with later designs proposing additional 20 mm Hispano-Suiza cannons, a 250 kg bomb beneath the fuselage, and two clusters of five 83 mm rockets under the wings. Nevertheless, the prototypes were left unarmed.
By late 1947, an order was placed for three prototypes. The first prototype underwent ground testing on 9 June 1948 and completed its inaugural flight on 17 July 1948, piloted by Captain Edmundo Osvaldo Weiss.
Operational history
Flight testing revealed excellent handling and performance capabilities. During a cross-country journey from Córdoba to Buenos Aires, the Ñancú achieved a speed of 780 km/h, setting a South American record for piston-engine aircraft that remains unbroken. Despite fulfilling its design objectives, the Fuerza Aérea Argentina decided to prioritize the jet-powered I.Ae. 27 Pulqui I as their future combat aircraft.
In early 1949, the sole flying prototype suffered significant damage during landing when test pilot Carlos Fermín Bergaglio miscalculated his approach. Although repair was feasible and no injuries occurred, the Fabrica Militar de Aviones opted to terminate the program and dismantle both the damaged prototype and two incomplete airframes stored at the facility.
Variants
- I.Ae 30 Ñancú
- Fighter/interceptor/heavy fighter/attacker model; three prototypes were initiated, with one flown before crashing and two unfinished airframes scrapped following project termination.
- I.Ae.30 Pallavicino I
- Jet-powered adaptation of the IAe-30 Ñancú designed by Cesare Pallavicino. Conceived as a single-seat fighter akin to the Gloster Meteor, it retained the IAe.30 fuselage but substituted inline engine nacelles with Rolls-Royce Derwent jet engines delivering 3,500 lb static thrust each. Featured an extended cockpit with a fully metal nose housing four 20 mm Hispano-Suiza autocannons in place of six mounted below it. None were constructed.
- I.Ae.30 Pallavicino II
- An evolution of Pallavicino I featuring elongated swept wings and a more angular tail design. Intended as a light bomber/attacker accommodating two crew members (pilot and navigator). Armament included four 20 mm Hispano-Suiza autocannons, two internal bombs weighing either 900 or 1,000 kg each, and capacity for twenty 75 mm air-to-ground rockets. No units were built.
