Abstract

Una tapa mejorada para estructuras que se someten a vibraciones y movimientos inducidos por vórtice debido al flujo de flujo alrededor de la estructura. Una modalidad incluye un perfil aerodinámico en el borde de la tapa. El perfil aerodinámico puede agregarse a tracas existentes o puede formarse al mismo tiempo que la traca para tracas extruidas. El perfil aerodinámico reduce las vibraciones y movimientos inducidos por vórtice de la estructura a la cual se une la traca. Otra modalidad de la invención proporciona un soporte resistente a la tensión unido a la traca y a la estructura. El soporte proporciona una trayectoria de carga diferente a lo largo de la traca que la técnica previa para llevar la carga de presión desde la presión de fluido que actúa en forma normal a la superficie de la traca.
