Abstract

"MéTODO PARA ESTIMAR A VELOCIDADE DE AR DE UMA AERONAVE DURANTE CONDIçõES DE BAIXA VELOCIDADE DE AR, E, SISTEMA DE DADOS DE AR PARA UMA AERONAVE DE ROTOR". Um método de estimar a velocidade de ar de uma aeronave durante condições de baixa velocidade de ar inclui medir uma pressão de impacto negativa usando uma sonda estática de pitot na aeronave. Então, o método inclui estimar uma velocidade de ar não zero da aeronave como uma função da pressão de impacto negativa medida.
