I.Ae. 27 Pulqui I Totally Explained

Everything about I Ae 27 Pulqui I totally explained

The I.Ae. 27 Pulqui I was an Argentine jet fighter designed at the "Instituto Aerotecnico" (AeroTechnical Institute) in 1946.

Design and development

The design was created by a team led by the French engineer Émile Dewoitine which included engineers Juan Ignacio San Martín (mil.), Enrique Cardeilhac and Norberto L. Morchio.
The fuselage was semi-monocoque with elliptical cross-section, air intake was in the nose and surrounded the cockpit. The reduced internal fuselage volume forced the fuel tanks to be installed exclusively in the wings, which resulted in a significant reduction of its range.

Testing and evaluation

The prototype flew on 9 August, 1947 wth test pilot 1st. Lt. Osvaldo Weiss at the controls. The history of this aircraft was brief, as its performance was considered unsatisfactory and in the meantime the studies for the more evolved FMA IAe 33 Pulqui II were quite advanced. Nevertheless, its role in the history of aviation is quite significant as it was the first jet combat aircraft developed and built in Argentina and Latin America. This made Argentina the 5th nation in the world being able to accomplish this task by itself.
The restored prototype is currently at the National Aeronautics Museum ("Museo Nacional de Aeronáutica") of the Argentine Air Force ("Fuerza Aérea Argentina"), at Morón, Buenos Aires, Argentina.
