“…For this purpose, they conducted an analysis using a numerical 3-D model of the guide. Lluesma-Rodríguez et al [11] analyzed the aerodynamic drag when traveling through the tunnel at high speed. Under such conditions, the waves propagate, increasing the pressure in front of the object and thus the drag compared to the open flow case under these conditions.…”

“…Before starting the next course, the capsule is rotated, or just the rows of seats, so that passengers can travel facing forward (9). After the capsules are ready for the further journey, the door ( 10) is opened and the next passengers board (11). After boarding is complete, the door is closed (12) and the module moves toward the free lock (13).…”

The innovative concept of the vacuum railwayhigh-speed transportation system has for many years aroused great interest of people dealing with the issues of modern and effective transport systems. Transport scientists and engineers see this technology as a great opportunity for modern societies, at the same time, struggling with many difficult and still unsolved problems. This article presents partial results of the research carried out to assess the feasibility and legitimacy of implementing this technology in Poland. Particular attention was paid to the research methodology for estimating the demand for passenger capsules used for the transport of people in hyperloop (HP) technology. The authors also presented the results of using this methodology to determine the investment outlays for HP capsules intended to handle passenger traffic on selected routes planned in Poland. The authors' contribution is an innovative approach to determining the demand for passenger capsules, the investment outlays, and the maximum capacity depending on parameters such as, for example, the sequence time or travel time of capsules on one of the future HP routes in Poland.

“…Reduced air resistance could permit vactrains to travel at very high speeds with relatively little power. Unlike conventional high-speed trains, capsular vehicles are individual vessels carrying passengers and freight with the expected maximum speed of near 1200 [km/h] in a nearvacuum tunnel and CFD (Computational fluid dynamics) works have been performed to validate feasibilities [14][15][16]. Capsular vehicles have a lot of advantages over traditional on-ground transportations like high speed, capacity, fuel efficiency, operational cost, environmentally friendly, etc., [17][18][19].…”

High-speed capsular vehicles are firstly suggested as an idea by Elon Musk of Tesla Company. Unlike conventional high-speed trains, capsular vehicles are individual vessels carrying passengers and freight with the expected maximum speed of near 1200 [km/h] in a near-vacuum tunnel. More individual vehicle speed, dispatch, and position control in the operational aspect are expected over connected trains. This numerical study and investigation evaluate and analyze inter-distance control and their characteristics for high-speed capsular vehicles and their operational aspects. Among many aspects of operation, the inter-distance of multiple vehicles is critical toward passenger/freight flow rate and infrastructural investment. In this paper, the system’s equation, equation of the motion, and various characteristics of the system are introduced, and in particular control design parameters for inter-distance control and actuation are numerically shown. As a conclusion, (1) Inter-distance between vehicles is a function of error rate and second car start time, the magnitude range is determined by second car start time, (2) Inter-distance fluctuation rate is a function of error rate and second car start time, however; it can be minimized by choosing the correct second car start time, and (3) If the second car start time is chosen an integer number of push-down cycle time at specific velocity error rate, the inter-distance fluctuation can be zero.

“…The frontal surface and shape of the pod may affect the aerodynamic drag and the tube's operational energy consumption [5,14,28,31,36,39,51]. The Kantrowitz limit, the blockage ratio, the drag coefficient, and the pod's length are certain factors for optimizing the aerodynamic performance and pod speeds [5,18,22,24,26,27,34,41,43,51,60].…”

The hyperloop is an innovative land transport mode for passengers and freight that travels at ultra-high speeds. Lately, different stakeholders have been engaged in the research and development of hyperloop components. The novelty of the hyperloop necessitates certain directions to be followed toward the development and testing of its technological components as well the formation of regulations and planning processes. In this paper, we conduct a comprehensive literature review of hyperloop publications to record the current state of progress of hyperloop components, including the pod, the infrastructure, and the communication system, and identify involved EU stakeholders. Blending this information results in future directions. An online search of English-based publications was performed to finally consider 107 studies on the hyperloop and identify 81 stakeholders in the EU. The analysis shows that the hyperloop-related activities are almost equally distributed between Europe (39%) and Asia (38%), and the majority of EU stakeholders are located in Spain (26%) and Germany (20%), work on the traction of the pod (37%) and the tube (28%), and study impacts including safety (35%), energy (33%), and cost (30%). Existing tube systems and testing facilities for the hyperloop lack full-scale tracks, which creates a hurdle for the testing and development of the hyperloop system. The presented analysis and findings provide a holistic assessment of the hyperloop system and its stakeholders and suggest future directions to develop a successful transport system.
