Abstract

Introducing NAR technology, in which a suction / blower fan fixed on the front of the fast running vehicle, receives the resistance producing air from the front and blows it out from up/down and both the sides of the vehicle (be it a rail/road or water transport vehicle) through deflector, windows and ducts specially arranged. With this technology, the proposed Pavan- Putra train attains a speed of around 550 Km/h with nominal power which can be extended up to 950 km/h by adding more fan /blowers, deflectors and air ducts.

Description

THE PAVAN-PUTRA TRAIN

DESCRI PTION: The Pavan-Putra Train is a faster and economical mode of transport using the NAR Technology which can be applicable for all sort of means of transport runs on rails/roads/water. Achieving higher speed and lowering fuel/energy consumption by neutralize all air resistance for forward motion. A specific model of this Pavan-Putra Tran is presented here to show the specific result of this NAR technique which can be applied to all sort of transport vehicles. The dimensions of this model can be varied as per requirement.

Background: With the growing population, globalization and standard of living the need of travelling & transportation are increasing extensively, increasing energy consumption and badly affecting environment. More electric/ solar and battery power are being used to meet energy demand but the faster transportation means are the new challenge with these new energy scenarios.

Railway is the most preferred, comparatively safe and economical means of transport for goods and passengers needs some improvement for faster movement. Other road and water transport means also needs improvement for lower energy consumption with faster speed.

'Sinkansen' was a very good effort to get fast speed. It is too expensive and consumes very high energy to provides limited maximum speed up to 350 km/h only. Laying down special type of rail track like - Flyperloop, VAC Train , Maglev train is not possible for all countries neither it is economical nor energy efficient therefore, a system which can use old infrastructure with minimum alteration as well as energy efficient will be preferred

Road transportation has its own limitations though it can run fast but are safer within a speed limit of 60 km/h. Also the road transport consumes 8 to 10 times more energy than railways.

Water ways are still a big means for heavy goods but is a very slow mode of transport.

One amazing fact of 'Indian vedic script 'suggests to keep 'sky undisturbed, pure and calm' to make mind of human beings balanced and healthy and so the complete physique healthy. This will compel us to minimize the use of aircrafts in future and will require alternative means for fast transportation like this.

Need of new and fast means of transportation is growing constantly. Intensive efforts to save energy are being made. A simply affordable, lowest energy dependable, safer, quicker transport system plyable for all types of surfaces/terrains and weather conditions and also environment friendly is required.

Disclosure: -The NAR technique neutralize all air resistance for forward motion. It comprises of a heavy duty air blowing or suction system like blower fan, an aerodynamic Nose Cover with openings, a Deflector and Ducts to pass air. This NAR Technique is very much useful for road transport vehicles like Buses, Trucks and Cars, train and trams , Boats, Steamers and Ships runs on conventional engines or battery/solar/electric powered.

In simple terms, this invention can be expressed as "an aeroplane running on steel rails (track) not using air thrust for forward movement but wheel power, powered by electric motors. In the invention, a new technique is developed to 'neutralize air resistance at higher speed¹, named as "NAR technique" which is a mechanism to encounter the huge air which obstructs vehicles while they try to attain more and more high speed. The amount of air resisting the speed of the vehicle depends upon the cross-sectional area and the speed of the vehicle. This huge volume of air, the product of two, works as liquid walls resisting the forward motion of the vehicle. This NART reduces this resistance effectively and economically and is applicable on all means of transport be it a rail, road or water for attaining higher/double speed with almost same amount of input power. (Some additional power will be required for NART system, which is comparatively very low.)

In the NART, the air causing pressure at face of vehicle is received by high capacity blower/ suction fan, making it zero by removing all the obstructing air on the front face and the air is flown backwards and is deflected by a deflector to all the sides in open air. Frontal nose cover of the train with side openings will avoid air turbulence and minimize the skin effect on the side walls of train and the rest amount of air received by fan is guided towards two ducts at the bottom. From the main duct, air will flow till the end of train avoiding the dragging effect and from an additional bottom duct, extra air releases to both the sides of the train before the beginning of 2nd bogie of the first coach (or will move even more backwards through additional duct in a longer system).

Unlike conventional trains, this train has 8 coaches of smaller in size and light weight with 3 wheels' bogie and NAR technique and can achieve a speed of 550 km/h with nominal power.

Best mode of Operation: -

In the Pavan-Putra train the NART system receives around 350 m3 of air per second and flows it out from the sides top and back of the cover and around 150 m3 of air is diverted by surface of its Nose cover gently as the outgoing air from the opening speeds up its movement. Thus, with the power needed to run at a speed of 160 km/h with the obstruction of 150 m3/sec air can now run up to 360+160=520 km/h and with the small additional power it can reach easily up to 550 km/h. At this speed the air cushion can de-rail the train but the horizontal wheel will hold the track and keep train on track.

This whole system of fan and ducts may be arranged in many ways and more fan blowers may be added in the main bottom duct in the middle and at the end of the train. By this whole system, train can neutralize almost all of the resisting effect of air.

Arrangement and Working Mechanism: The motor attached in the axle of the wheels of each bogie will give the forward movement and a speed of 550kmph can be achieved.

To minimize air resistance, the size of the coaches is reduced to [6'6" * 6'6"] of height and width and weight to 3 tons by using light weight metal and polymers and length is kept as small as 42' only. All coaches are divided into 7 compartments, each accommodating 4 to 6 passengers. Separate doors will be given to enter each compartment and such loaded coach will weight around 7 tons only and this will be resting on 2 bogies of 3 wheels each. Two wheels will be in one wheel set of standard gauge rail of 30" diameter in the back side of the bogie and the third single wheel which will run on an extra central rail will be in the front of the bogie having flat surface and no flanges on any side. Along with these single wheels, 2 horizontal wheels of 18" diameter each, will be fitted at the bottom level of third single wheel, running into the grooves of the central rail to keep the vehicle on ground. The "triple wheel assembly" -the single central wheel with two horizontal wheels, of each alternate bogies are powered with electric motor and are able to connect with gears to move while gripping the track, or remain free, if required. All the wheel sets are powered with 3 phase AC electric motors of 50 Kw each. Three wheel bogies are useful in new tracks, laid specially for it.

The old tracks, laid originally for conventional trains, if an extra central rail track is not possible, a light weight four-wheel bogie can be used in its place, in which 2 horizontal wheels are fixed in front of the front wheels set of the bogie on the extended arm of bogie frame, with the hydraulic jack to push wheels into the grooves of track and to pull out and fix into the grooves of inner track when the joining fish plates comes in the main track. This mechanism of watching and acting according to the fish plate joints will be operated by electronic sensors and camera devices. The first coach of Pavan-Putra train will be the pilot coach having special arrangements. The nose covers of the 1st coach is aerodynamically designed and made of light weight hard metal alloy, covering a high capacity blower fan and a deflector, extended up to pilot cabin and its total length is 19'. At the joint of pilot, cabin big openings are provided in all three sides (right, left and up) of the covers located just above the deflector surface to allow air to flow out. First 7' of front nose cover will be made of grills to receive air inside. The air is received in the area from top of the fan to 2.5' below the bottom of the fan and 4.5' width in the central part of the face. At the face of the floor of the first coach, a blower fan of 54" diameter is fixed in a 4' long barrel, which is operated by 200 kW motor, capable of flowing 400 m3/sec air with 1" static pressure. From a 3' gap, a pyramid shaped deflector is mounted on the front wall of the pilot cabin, having 5' of height. Upper surface of deflector starts from the head of the pilot cabin and joins the vertex of pyramid with 6'6" wide and 6.25' long (slant length). The upper surface of deflector is triangular shaped and is inclined at 35 degrees. The position of vertex of 6'6" by 6'4" sized deflector is at 3.75' to upper edge, 2.75' to lower edge and 3.25' to both sides. The bottom side of deflector starts from 2' above the floor of coach leaving space for two ducts. The center of the blower fan is focused at a height of 3.25' from the floor that is 6" above the vertex of deflector.

Below the bottom of this deflector, openings of 2 ducts are given, each one of 1' height and 6'6" width. Upper duct is the Main duct extended up to the tail end of the coach along with the floor of the coach and 2nd lower duct is the Additional duct below the Main duct extended up to 2nd bogie of the coach.

In each coach, between 1st bogie to 2nd bogie 2' wide air shield of light metal is fixed along the both sides of outer walls of bogie.

We can use any types of bogies, either the three wheeled or conventional 4-wheel bogie with additional 2 horizontal wheels into deep grooves of rail track and runs on side wall of track. It will have hydraulic jack connected to pull and push these wheel in and out when the joint of rail with fish plate is to obstruct it, an electronic sensor observe it and pull out wheel which are griped other sides to the added additional pieces of track inner side of both the main rail.

The central extra rail with groove will be designed specially. Total height of this central rail (track) is 50 mm above the main track, main body of central rail will be generally flat or evenly rounded unlike other two main rails. Width of this main body will be 73mm (3") and thickness will be 25mm (1") and groove of 25mm below the main body (or from the middle flange state up to the base) for the full track.

But for crossing and track changing point, central rail will be of adjustable height with the help of one additional plate to give this height of 50 mm required in central track otherwise it will be kept at same height for the conventional track.

Industrial Applicability: -This Pavan-Putra train, being light weight can ply on any surface (muddy, sandy, rocky or hilly) or terrain as its light weight track can be laid down on difficult terrains without heavy and high bridges. Also, it can run on a track of high slopes and gradients. It will reduce travelling time, costs and pollution. It will help to develop tourism. Many remote areas will become accessible. Light weight goods or perishable goods get valued by fast movement. Use of individual vehicles may decrease and help to reduce pollution and road traffic hazard.

The present invention provides higher speed with low cost investment in infra-structure, vehicle and running expenses of fuel.
