摘要: A multirotor aircraft that includes a chassis, three or more vertical rotors, one or more free wings and one or more fixed horizontal rotor. The free wing is attached to the chassis by an axial connection so that the angle of the free wing is changed relative to the chassis according the flow of air over the free wing. The fixed horizontal rotor enables the multirotor aircraft to lower and climb while flying forward at a stable horizontal pitch of the chassis.

摘要: An autonomous unmanned aerial vehicle for land, sea and air use. The autonomous unmanned aerial vehicle is more specifically related to an unmanned aerial vehicle, wherein the autonomous unmanned aerial vehicle is configured to vertically take off and vertically land, fly with fixed wings and stay in the air silently for a long time by means of a balloon inflated behind it.

摘要: A system and a method for improving a stall margin of an aircraft during a climb phase of flight are disclosed. In one embodiment, the method comprises using data indicative of a phase of flight of the aircraft and data indicative of an angle-of-attack, and automatically commanding a deployment of leading edge slats movably attached to wings of the aircraft when the following conditions are true: the aircraft is in a climb phase of flight; and the angle-of-attack equals or exceeds a predefined deployment angle-of-attack threshold value.

摘要: A land-and-air vehicle configured to switch between a first form to be taken during ground traveling and a second form to be taken during flight includes a main body, a main wing unit, an operation unit, and a controller. The controller is configured to control, on the basis of an operation performed on the operation unit by an operator, a behavior of the land-and-air vehicle during the ground traveling and during the flight. The operation unit includes a handle and a step. The handle of the operation unit includes a throttle unit. The controller is configured to control, both during the ground traveling and during the flight, yawing of the land-and-air vehicle in response to an operation performed on the handle, and to control thrust for the land-and-air vehicle during the flight in response to an operation performed on the throttle unit.

摘要: Noise-abatement for a leading edge wing slat is provided by a noise-abatement airflow shield integral with the lower trailing edge of the slat, wherein the shield is reciprocally autonomously curveable from a substantially planar configuration when the slat is in a retracted position thereof and into a convexly curved configuration when the slat is in a deployed position thereof.

摘要: An electrically powered vertical takeoff and landing aircraft (EVTOL) includes a payload module, a plurality of electrical power sources. a wing, and a plurality of electric thrust generators. The wing is pivotally attached to the payload module and is configured to pivot about a pivot axis, relative to the payload module, to transition between vertical flight and horizontal flight. The electric thrust generators are operatively attached to the wing, where each one is operatively connected to a different electrical power source. The electric thrust generators operate to provide thrust to the aircraft in response to receiving electric power from the electrical power sources. The electric thrust generators pivot, with the wing, about the pivot axis, relative to the payload.

摘要: Installation of powered actuators in the leading edge of a control surface in order to have a better weight distribution. The systems described herein propose an actuation system with a static ground structure used to move a control surface of an aircraft. The actuation system, and the ground structure are aligned with the center of rotation of the control surface, providing the aircraft with flutter suppression. This proposal is an approach to use the actuator in a place favorable to the mass balancing and reducing or even dismissing the usage of mass balancing, saving weight and cost.

摘要: Disclosed is a VTOL aircraft, and a method of operating the same. The VTOL aircraft employs a propulsion system comprising at least one propulsion unit, which can be rotated to generate lift during VTOL operations and thrust during cruise. A folding wing is employed to provide lift during cruise, and to meet external size constraints during storage and VTOL operations.

摘要: Convertible-type aircraft, able to fly with the speed and the reduced operating costs of a fixed-wing aircraft and also to take-off/land vertically and hover/manoeuvre like an helicopter.
The aircraft object of the invention comes in the form of a classical plane, with a fuselage (1), a fixed wing (2), an horizontal stabilizer (3) and a vertical fin (4), as well as one or several jet engines or turboprops (5) for propulsion and it comprises exposable rotors (6 and 7) installed inside the wing and possibly inside the horizontal stabilizer or the fuselage for lifting the aircraft for vertical take-off/landing and stationary flight.
For the flight and the horizontal take-off/landing, the rotors are completely enclosed inside the wing and possibly inside the horizontal stabilizer or the fuselage.
