Muniz M-11
From Wikipedia, the free encyclopedia
The Muniz M-11 was an experimental two-seat high-wing strut-braced monoplane trainer for the Brazilian Air Force,[1] which designated it TP-1 (Treinador Primário modelo 1 [Primary Trainer model 1]).[2] The design is due to Col. Antonio M. Muniz, director of the Brazilian Technical Division, Army Air Service.[3]
Manufacture of Muniz designed aircraft was initially the responsibility of Companhia Nacional de Navegação Costiera (CNNC), set up as a military aircraft workshop in the 1930s. The company was renamed Fabrica Brasileira de Avioes in the early 1940s.[4] CNNA (Companhia Nacional de Navegação Aérea) took over manufacture of all Muniz designed aircraft c. 1941.[5] The Muniz M-11 design then evolved into the CNNA HL-1. It was powered by a Continental flat-four A65-8 44.7 kW (60 hp) engine. As the HL-1, it was in production until 1950.[6]
