    Abstract: Embodiments provide an electric aircraft with a plurality of lift fan assemblies that are configured to provide vertical lift, and one or more pusher propellers that are configured to provide forward thrust. The lift fan assemblies may be coupled to the wings of the aircraft via one or more support structures, and the wings may be coupled to an upper region of the fuselage. The pusher propeller(s) may be coupled to a tailing end of the fuselage. The lift fan assemblies and the pusher propeller(s) may provide thrust and movement in directions that are orthogonal to one another. A control system coupled to the aircraft may control the lift fan assemblies and the one or more pusher propellers to activate, increase in power, and decrease in power. The lift fan assemblies and the one or more pusher propellers may be operated separately, and may be active at different times.

    Abstract: A ground effect craft having a ground effect wing, a plurality of sponsons, and a control system is disclosed. The ground effect wing may include a fore ground effect wing and an aft ground effect wing. The ground effect wing may generate a stabilizing moment on at least one sponson to stabilize the ground effect craft. The plurality of sponsons may be dynamically coupled to the body. The plurality of sponsons may be dynamically coupled to each other. The dynamic coupling may permit the sponsons to move relatively independent of the body and each other, thereby stabilizing the ground effect craft. The ground effect craft may include a stabilizing wing.

    Abstract: La presente invención se refiere a una técnica para el acoplamiento de la sección de terminación de larguerillos (5) con costillas, cuadernas u otros elementos estructurales (2). Un elemento estructural de una estructura de material compuesto para aeronave comprende al menos un par de escuadras (13a, 13a') formadas integralmente con el elemento estructural, en el cual las escuadras están configuradas, y dispuestas relativamente entre sí, para copiar la forma de la sección transversal de la sección de terminación de larguerillo, de tal modo que cuando una sección de terminación de un larguerillo esté situada dentro de un espacio definido entre las escuadras, el pie de larguerillo esté emparedado en su sección de terminación entre una parte de las escuadras y la cubierta de revestimiento (12, 12'). Se aumenta la transferencia de carga en la interfaz entre las terminaciones de larguerillos y el elemento estructural, y se minimizan los problemas de despegado o pelado en la sección de terminación de larguerillo. La invención se aplica preferiblemente a un estabilizador horizontal de cola que tenga unas cubiertas de revestimiento superior e inferior (12, 12') obtenidas como órganos unitarios.

    Abstract: Method for dynamically limiting the inclinations of monoblock flight control surfaces (FCS) in an aircraft. Dynamic limitation of the FCS is activated if a stall susceptibility condition is detected in the current aircraft environment. The real-time calibrated airspeed of the aircraft, real-time angle of attack (AOA) of the aircraft, and real-time sideslip angle (AOS) of the aircraft are obtained. The aircraft parameters may be obtained via estimation if the measured values are deemed unsuitable. The real-time local AOA and AOS of the FCS are calculated based on the obtained aircraft parameters. The inclination of each of the FCS relative to the critical values is dynamically limited according to the calculated real-time local AOA and AOS of the FCS. The aircraft may be an unmanned aerial vehicle (UAV) and/or a V-tail aircraft. The stall susceptibility condition may include icy conditions.
