DETAILED DESCRIPTION
[0052] In efforts to reproduce energy efficient flight and provide the user with a new a unique experience, the following discloses a personal flying apparatus 2 which mimics the biomechanics of bird flight. Such a personal flying apparatus would have many useful applications. Since the proposed personal flying apparatus has an ornithopter-based design, it is devoid of spinning rotors. This makes the apparatus safer for human use and allows for a user to come in closer contact with other humans, animals, structures, or other aspects of their environment to which a rotor-based mechanism would pose a safety risk. Furthermore, the lack of spinning rotors makes the personal flying apparatus quiet and unobtrusive. This would be advantageous in wildlife observation or in military applications where stealth is necessary. Finally, two independently operable wings, combined with human athleticism, provide for excellent maneuverability.
[0053] The disclosure pertains to a personal flying apparatus which facilitates flight using bird-like flight biomechanics.
[0054] In an alternative embodiment, the skeleton of the wing structure and the wing itself could be positioned below the harness or above the harness as shown in
[0055] The flying apparatus 2 further includes leg braces 10 and 12 for support the legs of a user in a prone position. The leg braces 10 and 12 are preferably hingedly connected at 14 to the first torso strut 6 and second torso strut 8, respectively. In a preferred embodiment shown in
[0056] The hinged connection 14 allows an athlete to move their legs relative to the torso struts 6 and 8, allowing the athlete to run. This is particularly useful for preferred landing and takeoff techniques. Once an athlete is in the air, the hinged connection locks into place to keep the user in a prone position from torso to knee. The hinged connection 14 can be of any configuration known to a person skilled in the art. Examples of locking mechanisms include, but are not limited to, pin and slot, magnetic, or electro-magnetic couplings. In one embodiment, the hinged connection is auto locked in place once the athlete is in flight. Alternatively, the athlete can activate the locking mechanism with a particular motion or through a user interface as discussed below. In this embodiment, it can be appreciated that an onboard processing unit would auto lock the hinged connection 14 should the athlete fail to lock the leg braces 10 and 12 to the torso struts 6 and 8 respectively.
[0057] In the preferred embodiment, the leg braces 10 and 12 are locked in an in-line manner with the torso struts 6 and 8 respectively. However, in an alternative embodiment shown in
[0058] The leg braces 10 and 12 and torso struts 6 and 8 are coupled on each side of the athlete to wings 18 and 20. The wings are designed to mimic the shape and mechanics of a bird. In a preferred embodiment the wings 18 and 20 are comprised of two distinct sections: a humerus 22 and a radius 24. As shown in
[0059] The humerus 22 is coupled to the radius 24, allowing the humerus 22 and radius 24 to move relative to each other. In one embodiment, the humerus 22 and radius 24 are integrally formed, having different properties to allow the humerus 22 and radius 24 to facilitate different movements of each portion of the wing. An example of this embodiment would be using a spring plastic that is thicker in the humerus 22 portion than the radius 24 to allow the radius 24 to have increased flexibility and mobility when compared to the humerus 22 during the various portions of the flight pattern. In the preferred embodiment shown in the figures, the humerus 22 is coupled to the radius 24 via a hinge. In a further preferred embodiment, the wing hinge 28 extends along the majority of the width of the wing. However, it can be appreciated that the hinge can also be adapted to be positioned only between the humerus 22 and radius 24.
[0060] The wing preferably includes a series of reinforcements 30 to provide stability to the wing. In this embodiment, the wing also includes a flexible wing material 32 (as shown in
[0061] Mechanics, such as motors, linkage mechanisms and electronics are preferably primarily positioned in a control cylinder 17 mounted on an arch 19 to space the mechanics from the athlete. In one embodiment, this arch 19 can be configured to support the user in a potential crash by acting like a roll bar. In an alternative embodiment the mechanics can be situated in any of the structural components, including but not limited to struts 6 and 8, or wing structures 22 and 24. In one embodiment, the humerus and radius are at least partially hollow to allow for the linkages to be internal. The hollow nature would further aid in weight reduction of the personal flying apparatus 2. In another embodiment, shown in
[0062] To provide increased efficiency and battery life, the wings, in part, or in full can incorporate springs which are biased to the upmost phase of the wing motion. Thus, the battery, and drive system pull the wings down, and the springs either fully or partially return the wings to the upright position. This replicates bird mechanics as approximately four times the amount of muscle strength is required for the bird's downstroke compared to their upstroke. As can be appreciated the use of the word spring in this embodiment should not be limited to traditional springs but can include any material capable of biasing the wing to recoil on the upstroke, including but not limited to, metals, elastics, rubber, or other suitable material. In one embodiment, only the humerus section of the wings incorporates a spring. Alternative passive return mechanisms would be known to a person skilled in the art. Alternatively, the wings could be biased to the lowest position of the wing flight pattern.
[0063] In a preferred embodiment, the athlete is equipped with a tail apparatus located between or extending from the athlete's lower legs, below the knee. One example of a tail structure could be an elastic like sail material between the legs. The tail is used to help direct the flight path of the athlete, particularly to adjust the roll of the athlete during flight. In a further embodiment, there is optional fabric between the legs at a section above knee to add further lift and to aid with aerodynamics. As with the tail apparatus the leg fabric would be configured to ensure the users leg motion is unimpeded. In one embodiment, this is made of an elastic like material. Other configurations would be known to a person skilled in the art.
[0064] The apparatus further includes a processing unit 36 and battery 34. With the surge in battery related research and development, there are a plethora of possible lightweight batteries that can provide the required power to move the wings 18 and 20 to provide the required force to keep an athlete airborne.
[0065] This concept has also been proven in drone research where drones can hold payloads of hundreds of pounds. As an example, lithium-ion batteries can provide the required battery energy density necessary to power the personal flying apparatus 2. Alternatively, there has been substantial development in silicon-dominant battery chemistry which may provided greater battery energy density that current lithium-ion batteries, while providing faster charging. While a single battery 34 is shown in the figures, the inclusion of one or more additional batteries 38 would be understood to a person skilled in the art. These additional batteries could be secured in any suitable location to the personal flying apparatus 2, however, in a preferred embodiment, additional batteries 38 are coupled to the leg braces 10 and 12 as shown in
[0066] The processing unit 36 is contains a controller which manages the wing flight pattern. It further controls the locking mechanism of the hinged connection of the torso struts 6 and 8 to leg braces 10 and 12 respectively. Additionally, the processing unit is coupled to an athlete user interface 40, shown as a screen in
[0067] The user interface further allows for the user to provide input to customize the flight experience. For example, the athlete can speed up or slow down the wing flight pattern, initiate landing, provide navigation information, show battery levels, display flight statistics, and show any incoming or surrounding risks. The user interface is preferably voice controlled to provide maximum speed of response and to allow for hands free interactions. In another embodiment, the user interface further includes touch screen technology.
[0068] In a preferred embodiment, the helmet is equipped with a support strut 45 to reduce athlete neck strain. This support strut 45 can be partly flexible, particularly to allow the user to raise their head to look forward. While this support strut is illustrated in
[0069] The personal flight apparatus 2 preferably includes parachute as a safety feature. In particular, the harness 15 is equipped with a parachute 43 which cooperates with a number of sensors to initiate release of the parachute if the athlete is in danger. For example, the processing unit receives input from sensors which monitor the elevation, rate of decent and system performance. If any of the sensor readings are outside of a predetermined normal range, the processing unit can issue a warning to the athlete and release the parachute. In alternate embodiments, the weight of the parachute can be supported by an additional frame or existing support structure to reduce the weight carried by the athlete.
[0070] While the present disclosure has focused on a personal flying apparatus for a single athlete, it can be appreciated that the structure could be easily adapted for tandem flying. For example, the harness could be tiered, such that a second user harness is coupled to and located below the first harness. This allows a second user to be positioned with their back against a first users stomach. Alternatively, two harness, torso and leg strut assemblies could be positioned in a side-by-side manner between the wings to allow for tandem flight.
[0071] Air Flight Pattern
[0072] As disclosed above, the flight pattern of the wings is designed to mimic bird flight. The preferred mechanics of the wing flight pattern are shown in
[0073] The flight pattern is optionally and preferably accompanied by a rotational motion at the joint between the humerus 22 in a vertical-longitudinal plane of the flying apparatus 2 along the connection between the humerus 22 and the torso strut 6 or 8. This forward rotational motion is illustrated in the cross view of the humerus 22 in
[0074] While in the preferred embodiment, the motion of the wings would be controlled by the processing unit and controller, it should be noted that hand controls, voice commands, a joystick or any other suitable control mechanism or combination of control mechanisms could also be used.
[0075] The athlete can at least partially control the trajectory of their flight by controlling the roll of the flight apparatus 2. As shown in
[0076] Take Off
[0077] While there are multiple methods of take off, there are three preferred methods what will be described herein: the cliff method, a ramp method and a power-up method.
[0078] a) The Cliff Method
[0079] In a preferred embodiment shown in
[0080] b) The Ramp Method
[0081]
[0082] In a preferred embodiment, the roller board 54 has wheels 58 which run in tracks 60. This ensures that the roller board 52 follows a known and predictable path and keeps the roller board 52 coupled to the ramp without lift.
[0083] c) Power-Up Method
[0084] In another embodiment, the user is held in a support structure in an elevated and horizontal position. The wings are engaged to flap and the user is lifted from the support via the power of the wings. Alternatively, the harness is clipped into the support and the user is not released until sufficient power has been generated by the flapping wings to elevate the user safely.
[0085] Landing
[0086] When the athlete is prepared to land, they initiate a landing sequence through the user interface 40. This prompts the processing unit 36 to adjust the wing flight pattern and wing configuration to initiate slow and controlled the decent of the athlete towards the ground. Sensors are used to monitor the athlete's elevation. Once the athletes are lowered to a suitable elevation, the processing unit initiates the release of the locked hinged connection 14 which allows the leg struts 10 and 12 to move independently from the torso supports 6 and 8, respectively. The athlete allows their legs to drop and moves to a more upright position. This not only allows the athlete to meet the ground with their legs in motion to absorb the shock and momentum of the landing, but also puts the wings in a position that is generally perpendicular to the ground. This allows the wings to act as strong breaks to slow the athlete and reduce the momentum and speed that must be overcome to bring the athlete to a stop.
[0087] In a preferred embodiment, the athlete slows themselves, by turning, slowing the speed of the wings through the flight pattern or by adjusting the configuration of the wing with louvers. In a preferred embodiment, the wings have louvers on the trailing edge thereof that are pulled inwardly to shorten the length of the wing and decrease the concavity of the bottom surface thereof. As the athlete reaches the ground and their leg braces are released, the louvers can extend upward to provide a drag force to slow the athlete. This louver activation pattern mimics that used in aircraft flight.
[0088] In an alternative embodiment, the athlete can simply use a parachute to facilitate landing.
