History
First flight	9 August 1947

The I.Ae. 27 Pulqui I was an Argentine jet designed at the "Instituto Aerotecnico" (AeroTechnical Institute) in 1946. Only one prototype was completed; unsatisfactory performance led to the aircraft being superseded by a later design.

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, Cesare Pallavicino and Norberto L. Morchio.

The fuselage was semi-monocoque with an elliptical cross-section housing a single Rolls-Royce Derwent 5 engine with the air intake in the nose and the ducting surrounding the cockpit. The reduced internal fuselage volume forced the fuel tanks to be installed in the wings, which resulted in a significant reduction of its range.

Operational history

The prototype flew on 9 August 1947 with test pilot 1st. Lt. Osvaldo Weiss at the controls. The history of this aircraft was brief, limited to testing and evaluation of the only prototype, as its performance was considered unsatisfactory and in the meantime studies for the more developed 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 aircraft developed and built in Argentina and Latin America.
