The Aeromovel is an automated transportation system operating on an exclusive elevated track. It uses pneumatic propulsion, eliminating the need for onboard motors or transmissions. This results in low energy consumption and construction costs, thanks to its lightweight and slender structures. The vehicle is characterized by its low dead weight, particularly because it does not carry propulsion equipment. The Aeromovel uses steel wheels and tracks, and its propulsion system is located outside the vehicles.
Aeromovel Propulsion System
The Aeromovel technology is based on pneumatic propulsion – air is pressurized by highly efficient stationary fans into the elevated track. The air pushes or pulls a propulsion plate attached to the vehicle, which moves on steel wheels over railroad tracks. The propulsion circuits create exclusive and independent control blocks for each moving vehicle.
The Aeromovel’s fans are powered by electric motors, located below the stations, at ground level, or in an elevated technical floor. Because these components are outside the vehicle, they have a much longer lifespan compared to onboard motors. Additionally, they are not subjected to constant shocks, vibrations, dust, or abrupt temperature changes.
Elevated Track of the Aeromovel
The elevated track of the Aeromovel consists of three parts: the infrastructure (foundations and blocks), the mesostructure (pillars and support beams), and the superstructure (beams), with the latter made of steel or concrete. These structures are designed to be lightweight and slender, facilitating their assembly. They are built with precast or prefabricated pieces, minimizing interference at the implementation site and allowing for quick assembly. The modular pieces are adjusted according to the terrain’s characteristics and are manufactured with millimetric precision, using modern construction techniques.
The beams are also considered a part of the system’s technology, as they house many of the accessories and equipment. They serve the following functions:
☞ Supporting the vehicles and equipment;
☞ Allowing the pressurization of the system responsible for vehicle propulsion;
☞ Guiding the vehicle, as the tracks are mounted on them;
☞ Providing an emergency walkway for passenger rescue.
Aeromovel Vehicles
Aeromovel vehicles are not driven by their wheels, unlike other similar systems. Instead, the vehicles are passive, being externally propelled by controlling the air pressure and flow within the propulsion duct. They are constructed with lightweight and durable materials, using non-combustible composites and elements. Internally, they feature light, resistant, and easy-to-clean floors, ensuring passenger comfort and safety.
All components of Aeromovel vehicles strictly adhere to safety standards, including the American NFPA 130 standard, which addresses fire protection in rail transportation systems.
Aeromovel Structures
The structures that comprise Aeromovel technology are categorized into three main types:
Passenger Stations: These are the main structures of the system, built using the elevated track’s pillars for support. Usually made of exposed reinforced concrete, their architecture can vary according to the project and local culture. They are designed for easy access and automated operation.
Maintenance Centers: These are designated for corrective and preventive maintenance of the vehicles, as well as for storing spare components. There are two types of Maintenance Centers: one for AGT systems and another for APM systems.
Propulsion Motor Group (PMG): This location houses the motors and fans responsible for propelling the vehicles. All PMG buildings are acoustically isolated, constructed with masonry or metal structures, and feature acoustic panels with a minimum thickness of 75 mm.
