Key here are keels, factoring elsewhere in our anglophone data, in theory and in publications, but not yet as a tech term per se. The French "carène à l’alignement" is pertinent here as well. The "automatic" aspect of the stability here is theoretically inherent in aerodynamics achieved by way of construction and design. In other patents, automatic stability is achieved by means which are more per se mechanical.
