Abstract

SENSOR DE PESO SOBRE O TREM DE POUSO. Revela-se um sensor de peso sobre o trem de pouso para uso em uma aeronave com esquis de pouso possuindo um suporte e um sensor de deslocamento ligado ao suporte. O suporte possui um membro central que conecta um primeiro membro de extremidade a um segundo membro de extremidade. O membro central possui uma linha central e os membros de extremidade se estendem a partir da linha central do membro central. Membros de montagem se estendem ao longo da linha central do membro central para facilitar a ligação do suporte a um tubo transversal. O sensor de deslocamento conecta o primeiro membro de extremidade ao segundo membro de extremidade. O sensor de deslocamento é paralelo à, e afastado da linha central do membro central de modo que, quando um momento de curvatura for aplicado ao membro central, o primeiro sensor de deslocamento seja alongado ou encurtado.
