摘要： Illustrative embodiments may provide for an apparatus and method of controlling the folding of a wing. The apparatus may include a sensor, an actuator, and a wing fold controller. The method may include receiving a status of at least one of an aircraft and a wing fold system of the aircraft by the wing fold controller of the wing fold system. The method may also include receiving an automated command by the wing fold controller in response to receiving the status. The method may also include operating the wing fold system by the wing fold controller based on the automated command and the status. The method may also include transitioning a wingtip of a wing of the aircraft to one of a flight position and a folded position by an actuator of the wing fold system in response to commands from the wing fold controller.

摘要： A wing and propeller design may reduce the power required to propel an aircraft (400) in flight. This may be achieved by reducing downwash and trailing vortices that occur naturally on the aircraft's wings. A reduction in downwash and trailing vortices may in turn reduce the overall drag on the aircraft. In one embodiment, an aircraft includes a number of propellers (410, 420, ..., 450, 460) N prop , wherein each propeller comprises a diameter d prop , has a propeller efficiency η prop , and is configured to absorb power p prop to rotate at a rate RPM to generate thrust for a flight speed V of the aircraft. The aircraft may further include a total power p total absorbed by the propellers that is approximately p prop × N prop , a wing having a circulation distribution, wherein the wing comprises a wingspan B, a drag D that is approximately equal to p total × η prop / V. For V and B , the circulation distribution, d prop , and RPM substantially minimizes D.

In one or more embodiments, the disclosed method involves providing a sheath, and applying the sheath to the surface of the airfoil. In one or more embodiments, the sheath wraps around the surface of the airfoil from the leading edge of the airfoil towards the trailing edge of the airfoil. In at least one embodiment, the sheath covers approximately 50 percent to approximately 70 percent of the chord length of the airfoil. In some embodiments, the sheath is manufactured from at least one polymer, such as a polyurethane and/or a floropolymer. In one or more embodiments, the airfoil is a winglet, a raked wing tip, and/or a wing. (Fig. 1)

摘要： Lifting surface comprising:
• a movable discontinuity (1) located in the surface of the lifting surface, the movable discontinuity (1) being movable between:
o an active position in which the movable discontinuity (1) acts as vortex generator, and
o a passive position in which the movable discontinuity (1) is integrated into the surface of the lifting surface,

• a conduit (2) located in the spanwise direction of the lifting surface and in communication with the movable discontinuity (1), the lifting surface comprising at least two openings (3) in its surface spanwise distant from each other in communication with the conduit (2),
the movable discontinuity (1) and the conduit (2) being configured such that when an airflow goes through the conduit (2), this airflow activates the movable discontinuity (1) to act as a vortex generator of the lifting surface.

摘要： An aircraft, particularly a solar powered, high altitude, long endurance, unmanned aerial vehicle, is equipped with a combination of canted down, raked back wing tips 7 and trailing "tip tails" 10 carried on booms 9 from the tip regions of the mainplane 4. Each tip tail is positioned to be subject to the upwash field of the respective wing tip vortex, at least in the cruise condition of the aircraft. The wing tip form can achieve a reduction in induced drag and help to relieve wing root bending moment while the tip tails can act through their connections to the mainplane to provide torsional relief to the latter, particularly under lower incidence/higher speed conditions. In the higher incidence/lower speed cruise condition, however, the presence of the tip tails in the upwash fields of the wing tip vortices means that they can generate lift with a component in the forward direction of flight and hence contribute to the thrust requirements of the aircraft.

In addition, vortex generators might be attached to various types of athletic equipment. A mapping can suggest placement of a vortex-generator arrangement on an article, as well as prescribe particular vortex-generator arrangements for regions of a person.
