Abstract

resumo “sensor de velocidade de roda de aeronave” trata-se de um sistema de sensor de velocidade de roda de aeronave que inclui um par de condutores acoplados entre um sistema eletromecânico e um sistema de controle. o sistema de controle é configurado para aplicar um sinal de tensão portador ao par de condutores e para detectar um sinal de corrente modulado no par de condutores. o sistema eletromecânico inclui um estator e um rotor que se move mediante a rotação de uma roda de aeronave. o estator inclui um enrolamento disposto ao redor do rotor. o enrolamento é configurado para produzir o sinal de corrente modulado no par de condutores em resposta ao movimento do rotor. o sinal de corrente modulado tem uma frequência que depende de uma velocidade rotacional da roda de aeronave. a frequência da modulação é determinada por demodulação. a amplitude de pico do sinal modulado permanece constante em relação a toda a faixa de velocidades detectadas. o rotor pode ter vários dentes principais ao redor dos quais a bobina de estator é enrolada, sendo que cada dente principal tem vários dentes secundários na periferia interna. o formato dos dentes fornecidos no rotor pode corresponder ao formato dos dentes secundários no estator.
