Projects
In August 1925, he was sent to France to study aeronautical engineering at the École Supérieure de Aéronautique. During this time he developed several aircraft, which he named the M-1, M-2, M-3, M-4 and M-5. Only the Muniz M-5 was built by Caudron in 1929 with funds from the Federal government of Brazil and after successful test flights in France, was brought to Brazil. Upon his return to Brazil, he became director of the Técnicos da Aviação Militar and developed other aircraft, several of which were built and successful. During the 1st National Aeronautical Congress in 1934, Muniz proposed to produce airplanes domestically instead of always importing them. Eventually, the Companhia Nacional de Navegação Aérea was founded, which produced several of Muniz's designs.
