Description
TRAM TRANSPORTATION SYSTEM
Field of the Invention
This invention relates generally to a transport system for carrying people and cargo. More specifically the invention relates to a transport system that includes a tram to carry the people and cargo which has steering means for steering the tram along a preferred path.
Background
Transportation systems which utilize trams usually include a track on which the tram travels. Trams are thereby directed along predefined routes which are ideally separate from routes taken by other traffic, pedestrians and cyclists
Prior Art
Trams systems in the prior art include trams suspended from a cable. Typical examples are disclosed in: CN 201694190U (Yiqiang) and GB 115480 (Wells Reginald Fairfax).
Other tram systems include trams supported on a rail. Typical examples are disclosed in: WO 201625026 (Duren et al), CN 203958137U (Zheng et al), CN 102582636 (Zechen) and CN 101580066 (Longfei),
Too much effort and expense are required to design, build, and maintain extremely strong structures which suspend and support cables and rails.
In light of the foregoing prior art, there is a need for a tram system more particularly suited to the purpose of the trams which transport people and cargo.
Summary of the Invention
According to first aspect of the invention there is provided a tram transportation system comprising a tram and a supported guide cable, wherein the tram comprises: a cable guide for the tram to traverse along the cable, and a fuselage joined to lateral wings in which ducted fans direct air through the wings to lift the tram over the guide cable.
Advantageously the guide or first cable only steers the tram. Thus the cable and means of guidance are lightweight, inexpensive, and unobtrusive on the landscape.
In this way the first or guide cable or cable may be envisaged to guide the tram while moving from point A to B, determines the tram lifting level, and supports the tram in an emergency by taking a part of tram weight to reduce the deflection of safety cables.
The second or safety cable or cables instead support the tram on emergency by taking a part of tram weight to reduce the deflection of guide cables and suspend the electric power supply cable.
Preferably the wings extend from the bow to the stern of the fuselage. Advantageously there is a long lifting area of the wings so that less power is required by the ducted fans to lift the tram when flying forward.
Preferably the ducted fans are arranged in a row from the bow to the stern in each wing. Advantageously there is a long distance for a plurality of ducted fans which are able to lift the tram off the cable even when the tram is not moving forward. Power for driving the ducted fans proximate the bow may be increased relative the power to the ducted fans proximate the stern to raise bow to help the tram ascend and improve the lifting effect of the wings.
Preferably the wings are arranged to support the fuselage above the wings. People and cargo are carried in the fuselage which is above wings. People may step out of the fuselage onto the wings in an emergency and use the wings as a step when leaving tram.
Preferably the wings slant downward from a root where they are attached to the fuselage. Advantageously the tram rolls quickly which assists turning to follow the steer of the cable.
Preferably the wings are joined together at the root. Advantageously the wings may be formed as a single unit.
Preferably the profile of wings normal to the direction of the cable provided by the cable guide is concave. Advantageously a pocket of high pressure air is produced by the air driven by the fans into the concavity below the wings. This helps produce lift under the tram when the tram is moving forward to slowly to prevent stall of wings.
Preferably the wings have an airfoil shape for lift the fuselage while traversing along the cable. Advantageously, low power is required by the ducted fans when the tram is moving forward above the stall speed.
Preferably the fuselage encloses a passenger cabin. Advantageously the passengers travel safely and comfortably in the cabin.
Preferably the fuselage comprises exit doors for passengers to step out of the passenger cabin for example onto the wings. Preferably the exit doors are located intermediate two of the ducted fans in one of the wings. Passengers step on the station platform while loading and unloading, wherein wings may not be used to step on except in case of emergency.
Preferably the cable guide comprises a hook joined to an underside of the wing to retain the cable in a gap intermediate the hook and wing. Advantageously the tram lifts off the hook when the ducted fans are in operation to reduce friction between the cable guide and the fuselage.
Preferably the tram transportation system comprises a second cable, and the tram is guided by the first cable and the second cable which is parallel to the first cable. Preferably the cable guide is arranged so that the tram traverses along both cables. Preferably the tram comprises a set of safety cables located under and parallel to the guide cables, wherein both safety and guide cables may be used to lift the fuselage during an emergency situation.
Preferably the cable guide is located on the underside of the wings proximate where the wings are joined at the root.
Preferably the cable guide comprises a first portion proximate the bow and a second portion proximate the stern. Advantageously the cable applies a steering moment through the two portions to steer the tram and maintain the bow and stern in the fore and aft position as the tram moves forward.
Preferably the guide cables are pulled tightly with pre-tensioning force. Advantageously that provides stability to prevent the tram from rolling over.
Preferably the ducted fans in the starboard wing may rotate clockwise and the ducted fans in the port wing rotate counterclockwise. Advantageously the gyroscopic moment of the starboard ducted fans may cancel those of the port ducted fans so that tram is more easily turned by the cable guides which are guided by the cable(s).
Preferably the tram transportation system comprises a passenger unloading platform for passengers to alight from the fuselage.
Preferably the cable(s) is strung below the unloading platform to support the tram where one of the wings is under the unloading platform for unloading passengers. Advantageously the passengers may step out of the fuselage on the unloading platform. The platform shields the wing underneath the platform. The wing cannot be harmed by shoes of passengers or by their luggage or by cargo loading.
Preferably the unloading platform comprises a tram support to support the weight of the tram at rest or during landing. Advantageously the ducted fans may be powered down while the tram is docked at the unloading platform.
Preferably the tram support is arranged to withstand horizontal forces of bringing the tram to a stop at the platform. Advantageously the tram itself does not require a powerful braking means. In some embodiments there may be a motorized brake system fixed to the platform to stop the tram.
Preferably the tram comprises a propulsion means to propel the tram to traverse along the cable guide(s). Preferably the propulsion means comprises a propeller or jet fixed to the fuselage or in some embodiments wings.
Preferably the propeller or jet is substantially perpendicular to the ducted fans. In use the wings are horizontal with respect to the horizon and the propeller or jet directs thrust forward and backward in the direction from the bow to the stern of the fuselage.
