Abstract
Un paracaídas, perfeccionado, del tipo que posee en combinación con un dispositivo aéreo dotado de una forma de ala aerodinámica constituida por un elemento laminar superior, flexible, del cual se prolongan una serie de nervios que definen canales de paso de aire que se extienden desde un borde delantero del elemento laminar superior hacia el borde posterior del mismo, existiendo medios para la suspensión de una carga, útil del dispositivo aéreo, por medio de una serie de cuerdas de suspensión, caracterizado por comprender medios de anclaje para conectar las cuerdas de suspensión por lo menos a algunos de los nervios y elementos de distribución de esfuerzos montados en dichos nervios, para transmitir la tensión en dichas cuerdas de suspensión a zonas localizadas del elemento laminar flexible superior, entre el borde delantero y el borde posterior del mismo.
The ram-wing- A comparison of simple one- dimensional theory with wind tunnel and free flight results(One dimensional channel flow theory for ram wings, deriving lift and drag laws for comparison with wind tunnel and free flight tests results)
Flexible wings for maneuvering and landing application in the de-coupled concept(Flexible wings for hypersonic vehicles allowing for safe controllable landings, stressing leading edge parawing concept, flow visualization, lift- drag ratio, etc)
Influence of the vortex system of a wing in the absence of lift on the flow past the wing at small angles of attack(Air flow past small aspect ratio thick-section wing at small angles of attack, investigating vortex system effect on flow characteristics in absence of lift)
