Abstract

SE EXPONE UN SISTEMA ABORDO DE AERONAVES PARA MEDIDA, CALCULO Y VISUALIZACION DEL PESO TOTAL Y LA LOCALIZACION/REUBICACION DEL CENTRO DE GRAVEDAD. SE MONTAN TRANSDUCTORES Y TRANSMISORES DE TEMPERATURA Y PRESION EN RELACION A CADA UNO DE LOS PUNTALES (8) DEL EQUIPO DE ATERRIZAJE. ESTAS SEÑALES DE TEMPERATURA Y PRESION SE TRANSMITEN A UN MICROCOMPUTADOR DE CONTROL A BORDO CON REDUNDANCIA PARA PRECISION Y PROTECCION DE FALLOS. EL SISTEMA TAMBIEN INCORPORA UN PROGRAMA DE CORRECCION DEL SOFTWARE PARA CORREGIR Y COMPENSAR LOS CAMBIOS FISICOS EN LOS COMPONENTES DE LOS PUNTALES DEBIDOS A FLUCTUACIONES DE TEMPERATURA, FRENO DE SELLO (11) EN ANILLO E HISTERESIS CON LOS MODERNOS SISTEMAS DE ABSORCION DE CHOQUES EN LOS PUNTALES DEL EQUIPO DE ATERRIZAJE. EL ORDENADOR EFECTUA AJUSTES DE LOS CAMBIOS INTERNOS DE TEMPERATURA Y FRENO; CONVIERTE LAS ELEVADAS PRESIONES A LOS PESOS SOPORTADOS POR CADA PUNTAL Y CALCULA EL PESO TOTAL Y EL CENTRO DE GRAVEDAD DE LA AERONAVE. EL ORDENADOR TAMBIEN ESTA PREPROGRAMADOPARA ILUMINAR UNA "LUZ INDICADORA DE ATERRIZAJE FORZOSO" UBICADA EN EL DISPOSITIVO DE VISUALIZACION (29), CUANDO SE EXCENDEN Y SE DETECTAN DURANTE EL ATERRIZAJE LOS LIMITES DE PRESION PREPROGRAMADOS PARA CADA PUNTAL INDIVIDUAL. ESTAS LECTURAS DE PRESION SE ALMACENAN EN LA MEMORIA DEL ORDENADOR Y SE PUEDEN UTILIZAR DURANTE LA INSPECCION Y MANTENIMIENTO DE LA AERONAVE.
