  • Vertical takeoff and landing aircraft
    Patent number: 12491995
    Abstract: A vertical takeoff and landing (VTOL) aircraft includes a maximum takeoff weight (MTOW) of about 1700-kg, a cruising speed of about 80-knots equivalent airspeed (EAS) to about 100-knots EAS, a nominal range of about 300-km, a nominal flight time of about 4-hours, and at least one pair of rotors configured to provide vertical thrust. Each rotor of the at least one pair includes an about 2-meter propeller diameter, a disk loading of about 67-kg/m2 to about 110-kg/m2, and an operating speed of about 1800 rotations-per-minute (RPM) to about 2700-RPM.

  • AIRCRAFT WITH MULTIFUNCTIONAL STRUCTURE
    Publication number: 20250187758
    Abstract: An embodiment aircraft boom includes a boom member, a vertical stabilizer, a rear landing gear, and a front landing gear. The boom member may extend in a first direction and have a front internal structural member disposed therein, where a portion of the front internal structural member is a first attachment point for a first wing. The vertical stabilizer may extend from the boom member, where the vertical stabilizer has a rear internal structural member disposed therein and extends from the boom member and through an interior of the vertical stabilizer, and where a portion of the rear internal structural member is a second attachment point for a second wing. The rear landing gear may be coupled to the rear internal structural member. The front landing gear may be coupled to the front internal structural member of the boom member.
