Design and development

[edit]

Frederico A. Brotero, a chief-engineer at the Instituto de Pesquisas Tecnologicas, designed a light multirole aircraft that first flew in 1945. The IPT-7 was designed as a low-wing monoplane with fixed tailwheel landing gear and had a conventional tailplane. The fuselage and wings were of freijó wooden construction, which was planked with plywood made from domestic timbers. The pilot and passenger sat side by side in the cockpit, which could be entered through a sliding canopy. The aircraft was powered by a Franklin 4AC with 48 kW. Despite good flight characteristics, no series production took place.[2]
