Abstract

FIELD: transport.

SUBSTANCE: invention relates to high-speed ground-surface transport. Transport module is aircraft configured to displace on air cushion over shaped trestle erected at horizontal alignment. Said module is equipped with linear motor with transmission and airscrews to facilitate the development of dynamic air cushion and flight at minor altitude owing to feed under low-aspect wing at low flight speed and blow over low-aspect wing in cruising flight. Motor is fed via contactless electric power feed from circuit built in said trestle. Top section of shaped trestle represents a lightweight polygonal pavement with special coating made of low-adhesion materials.

EFFECT: safe and reliable motion, non-polluting transport facility, lower noise and fuel saving.

Description

The present invention relates to vehicles designed for advanced high-speed transport systems with the organization of movement along profiled guides mounted on racks above the earth's surface.

Currently, the urgent problem is the creation of a transport system, which is characterized by the absence of environmental pollution, the limiting noise limit, insignificant need for useful land, while it should provide cost-effectiveness, maximum safety, high speed of movement and low cost.

Known aerodynamic vehicle "Airtrain" (US No. 5535963, B60V 3/04, publ. July 16, 1996), moving along the monorail in the form of an inverted letter "T" at high speed. The structural and aerodynamic layout of the vehicle includes wings of small elongation (two wings in the bow and tail), as well as two electric motors with transmission to the opposite-rotor propellers. During movement, the vehicle does not touch the rail itself, with the exception of a spring-loaded contact that supplies the Airtrain with electricity. The vehicle performs braking by changing the angle of the propellers, and at low speed as well as the monorail. Depending on the model, the Airtrain can carry from 72 to 92 people at a maximum speed of 320 km / h.

The disadvantages of this vehicle are the high cost of construction and operation of the entire transport system, as well as difficulties with driving at high speeds.

The Aérotrain vehicle (GB No. 1106202, B60V 3/04, published on April 13, 1965) adopted as a prototype is known. It is constructed according to the scheme of an air cushion train moving along a reinforced concrete support web in the form of an inverted letter "T". The aerodynamic design of the train has a streamlined external shape, it contains a turbojet or turboprop engine located in the rear part, as well as special pockets - air intakes in the train body, from which air gets into the pallet cavity when it accelerates and when it reaches a certain speed, it lifts the train above the supporting canvas. The project was developed by French design engineer Jean Bertin. The Aérotrain vehicle can carry up to 80 passengers at a maximum speed of 430.4 km / h.

The disadvantages of this solution, when applied to ground high-speed transport, are unsatisfactory economic and environmental indicators due to the use and rather high consumption of hydrocarbon fuel (with lower passenger flow) in combination with increased noise and environmental pollution by combustion products.

The objective of the proposed technical solution is to eliminate the above disadvantages.

The technical result is achieved by the fact that the ekranoplan train is made in the form of a transport module equipped with a means of ensuring its movement and moving along a profiled overpass on an air cushion, while the transport module is made according to an airplane scheme and includes a fuselage with a crew cabin, passenger and cargo compartments , a wing of small elongation with vertically mounted end washers and with a negative transverse V, U-shaped tail unit and means of ensuring transport module, made in the form of a linear electric motor located in the nose of the fuselage, with transmission to the propellers and contactless power supply from the network mounted in the flyover, while the nacelles with propellers are installed on the consoles of the front horizontal tail assembly of the winged train equipped with rear edge mechanization all over, and the profiled overpass has a polygonal symmetrical shape.

The essence of the proposed technical solution is illustrated by drawings.

Figure 1 schematically shows the proposed ekranoplan-train (side view), Fig.2 - ekranoplan-train (top view), Fig.3 - ekranoplan-train (front view). Figure 4 schematically shows a cross section of a profiled trestle.

The ekranoplan train contains a fuselage 1, in the bow of which are mounted the front horizontal tail 2 and engine nacelles 3 with propellers 4, a rectangular wing of small elongation 5 with end washers 6. A U-shaped tail unit 7 is installed in the aft part of the fuselage 1.

The profiled overpass contains pillars-supports 8, made mainly of precast, monolithic reinforced concrete, mounted along the route at certain distances, and the span 9, which is a lightweight polygonal web with a special coating made of materials with low adhesion.

WIG-train operates as follows. Moving the transport module along the profiled flyover is provided by a means of moving it, namely using a linear electric motor located in the nose of the fuselage (not shown in the drawings due to its popularity), with transmission to the propellers 4. The front horizontal tail unit of the winged train is equipped with rear mechanization edges along the entire range for guiding the jets from the propellers 4 under the wing of small elongation 5. Thus, the propellers 4 carry out blowing under the wing of small elongation 5 on low speed of movement and blowing of a wing of small elongation 5 in cruising mode, which contributes to the formation of a dynamic air cushion (screen effect) and to ensure a low altitude of flight of the winged train.

End washers 6 mounted vertically in the end sections of the wing of small elongation 5 are designed to weaken the pressure equalization in the end parts of the wing of small elongation 5, as well as to improve directional stability relative to the profiled canvas of the flyover. End washers 6 are made of materials with low adhesion.

U-shaped tail unit 7, installed in the aft part of the fuselage 1, combines the functions of vertical and horizontal tail units, helping to reduce the effect of the screen on the stability and controllability characteristics of the ekranoplan-train.

Technical and economic advantages of the proposed technical solution are as follows:

- a relatively simple technical solution in embodiment, only the fuselage and supports with a polygonal top are needed;

- the implementation of the means to ensure the movement of the transport module in the form of a linear electric motor is most promising from the point of view of ecology and ensuring high speeds of movement of transport modules;

- Does not interfere or cut engineering communications, does not interfere with the movement of any type of ground transport in all directions;

- does not require alienation of land, with the exception of small plots for support, does not cut agricultural land and does not interfere with the cultivation of land.
