Resumen

En el vuelo hacia adelante, las cargas del viento afectan los helicópteros y provocan vibración. Este artículo analiza el comportamiento de un prototipo de helicóptero compuesto por dos palas cuando se somete a una carga de viento en contra, similar a la condición de vuelo de avanzo. Una Red Neuronal Artificial (RNA) procesa los datos experimentales para identificar el patrón de su comportamiento dinámico. Las pruebas condujeron al análisis de vibración para diferentes velocidades del viento. Además, los datos indican que la amplitud de vibración aumenta cuando las palas se someten a la excitación en la frecuencia fundamental y su primer armónico en pruebas realizadas sin inclinación del plano del rotor (vuelo estacionario). Por otro lado, la segunda prueba somete al prototipo a una inclinación de 5 grados sobre el disco del rotor. En esta prueba, la amplitud de vibración disminuyó en la frecuencia fundamental, y la amplitud relacionada con el primer armónico aumentó. La RNA alcanzó 100% de eficiencia en el reconocimiento de las condiciones de vuelo del prototipo.
