Abstract

SISTEMA ANTITORQUE PROPULSIVO PARA GIROPLANO. Trata-se de um giroplano sendo dotado de uma configuração aumentada na qual uma asa básica e um sistema antitorque propulsivo estão combinados e descritos. O sistema antitorque propulsivo inclui um sistema de empuxo antitorque no qual está instalada uma ventoinha de nível variável no interior da haste de apoio de cauda do giroplano e um bocal de empuxo antitorque está montado na extremidade da haste de apoio de cauda. A ventoinha é conduzida diretamente a partir do acionamento do rotor principal. A configuração e a localização da ventoinha permitem que a descarga principal proveniente do motor se misture com o fluxo de ar comprimido proveniente da ventoinha. O fluxo de ar misto proveniente da ventoinha e do motor passa através da haste de apoio de cauda e para fora do bocal de em puxo.
