The present application relates to a vehicle for land and air transportation.
The present disclosure pertains to a vehicle that can be driven on land and flown in the air as a fixed wing aircraft with improved short takeoff and landing (STOL) performance. Vehicles with land and air capabilities provide the ability for the vehicle to arrive quickly to a destination, or to reach a destination that would otherwise require multiple vehicles to travel to, such as separate land or air or water vehicles. Previous attempts at vehicles with both land and air capabilities have been attempted using a traditional fixed wing, non-STOL design; these vehicles require longer runways to takeoff and land from than an air vehicle with improved STOL capabilities, and thus require greater ground infrastructure and cost to support vehicle operations. Although strides have been made, shortcomings remain.
It is an object of the present application to provide an aircraft configured to include a fuselage with one or more wings coupled thereto. One or more wheels are also coupled to the fuselage and are configured to allow the aircraft to taxi, take off, and land. A propulsor is used to provide thrust to the fuselage and airflow over the wings.
It is a further object of the present application that the wings may be fixed in position. It is also configured to permit foldable wings that can fold along a line via a hinged system or pivot along an axis. The folding allows the wings to store in a smaller footprint.
Another object is to include safety functions into the fuselage. These may include indicator lights configured to illuminate or reflect an amount of light. Additionally, the aircraft includes occupant safety system with the likes of an airbag and even anti-lock brake system coupled to the one or more wheels, such as the drive wheel. These features may be included in any configuration or combination.
Ultimately the invention may take many embodiments. In these ways, the present invention overcomes the disadvantages inherent in the prior art. The more important features have thus been outlined in order that the more detailed description that follows may be better understood and to ensure that the present contribution to the art is appreciated. Additional features will be described hereinafter and will form the subject matter of the claims that follow.

Referring now to the Figures wherein like reference characters identify corresponding or similar elements in form and function throughout the several views. The following Figures describe embodiments of the present application and its associated features. With reference now to the Figures, embodiments of the present application are herein described. It should be noted that the articles “a”, “an”, and “the”, as used in this specification, include plural referents unless the content clearly dictates otherwise.
The vehicle of the present application may be represented in one or more embodiments. One embodiment of the invention comprises a land air and air vehicle which includes the following key components; (a) a fuselage, (b) a wing, (c) one or more driven propulsors on one or more wings; and (d) a component necessary for land/road operations. With respect to the propulsors, the propulsors are ideally located such that the airstream generated by the propulsors flows around the wing. The interaction between the propulsors and the wing is what provides the STOL capability. This means the propulsors are typically forward of the wing. Any number of physical arrangements of the propulsors in relationship to the wing are possible, including any portion of the propulsor “in front of”, “above”, “beneath”, “behind”, or even “inside” a portion of the wing so as to satisfy the design goal of causing an airstream generated by the propulsors to flow over/across the wing. The component for land use may be that of a “wheel” although this is not meant to be limiting as many other types of components may be used in varying quantities and locations relative to the fuselage body of the vehicle. The (a) fuselage, (b) wing, (c) propulsors, and the airstream generated by the propulsors over the wing interact to provide the vehicle with improved STOL capabilities. A (d) driven wheel is necessary to give the vehicle land/road capabilities.
Referring now to
It is understood that the propulsor 4 is configured to attach to a portion of wing 2 and to induce a flow of air over a portion of wing 2. Propulsor 4 provides thrust used to drive the vehicle 8 forward whether in the air or perhaps partially on the ground.
Furthermore, wheel 11 may be a drive wheel wherein it may be coupled to a power unit (i.e. motor) of some type to induce and/or restrict motion on the ground separate from that of propulsor 4. If more than one wheel 11 is used, all or less than all wheels 11 may be a drive wheel. Any number drive wheels may be powered via one or more power units. In some embodiments some of the wheels will be “driveless” so as to freely rotate as a result of induced motion to vehicle 8. It is understood that in one embodiment the propulsor 4 may communicate with the power unit such that a single “motor” may induce both land movement and air movement.
In
In one embodiment each propeller 6 is located forward of the leading edge 7 of the wing 2 and is mounted to the wing 2 by the nacelle 5. Though other forms of propeller location (not shown) such as but not limited to, inside the wing 2, behind the wing 2, under the wing 2, or on top of the wing 2 could be employed. In use, the propellers 6 selectively rotate to provide airflow, and therefore thrust. Due to the location and arrangement of the propellers 6 relative to the wing 2, the airflow from propellers 6 travels over some portion of the wing 2. This airflow increases the effective airflow over the wing 2. This also increases the effective coefficient of lift (CL) when the propellers 6 are turning. Consequently, the propulsors 4 substantially increase the amount of lift generated by the wings 2 which helps to allow a reduction in the wing area required for a given amount of lift or increasing the amount of lift for a given wing area. This propulsor and wing interaction provides improved STOL capabilities for the vehicle while operating in air mode.
Wheel 11 is coupled to the fuselage 1 through customary or traditional methods such as struts, gearing, in communication with the wing and/or a portion of the fuselage 1. Wherein wheel 11 is a drive wheel, it may be driven by a motor 12. Motor 12 may be located in direct contact with wheel 11, such as in a hub assembly, or may be in communication through one or more gearing assembly distal from the wheel 11. This may be seen through driving mechanically by a driveshaft, chain, or pulley for example.
