    Abstract: A method for determining a center-of-gravity of an aircraft in three dimensions includes determining a first center-of-gravity location for an aircraft in a first plane defined by a first axis and a second axis. The method includes positioning the aircraft in a tilted position by rotating the aircraft and determining a second center-of-gravity location for the aircraft in the first plane in the tilted position. The method includes comparing the first center-of-gravity location to the second center-of-gravity location to determine a component of the first center-of-gravity location along a third axis defined out-of-plane from the first plane to determine a three-dimensional center-of-gravity of the aircraft.

    Abstract: An aircraft is provided and includes a mission vehicle configured to follow vertical take-off and landing (VTOL) operations and to execute forward flight, hover/loiter and landing operations and a launch vehicle configured to drive the mission vehicle through at least vertical take-off (VTO) operations. The launch vehicle is umbilically coupled to the mission vehicle during the VTO operations and releasable from the mission vehicle thereafter.

    Abstract: An aircraft is provided and includes a single sensor and wings extending outwardly in opposite directions from a fuselage. Each wing includes a main section, an engine section supported on the main section and tail surfaces extending transversely relative to the main section. The single sensor is mountable to one of the tail surfaces with a field of view (FOV) representable as a spherical wedge having a dihedral angle exceeding 180°.

    Abstract: A retractable landing gear system for a vertical takeoff and landing (VTOL) aircraft includes a rotational strut rotatably coupled to a fuselage of the VTOL aircraft. The rotational strut includes a first end, a second end, and an intermediate portion extending therebetween. A drag strut includes a first end portion pivotally connected to the rotational strut and a second end portion. A locking link includes a first end section pivotally connected relative to the fuselage, a second end section pivotally connected to the drag strut and an intermediate section having a hinge element. A retraction system is operatively connected to the rotational strut and the locking link. The retraction system is operable to pivot the drag strut about a first axis and rotate the rotational strut about a second axis that is distinct from the first axis.
