However,
China about tame their biggest:
The biggest concern for Maglev, magnetic levitation trains, is it finally resolved? Meanwhile, A group of Chinese engineers would work on a solution to the challenge of the “boom tunnel”.
The latest prototype of the Chinese maglev is likely to be talked about. In addition, But for once, the comments should not only focus on the performance of the magnetic levitation train. For example, The new generation of the high -speed train. Consequently, 600 km/h all the same, would be about to bring down a technical barrier which has blocked its development so far: the “Boom tunnel”.
This phenomenon characterizes one of the main problems of Maglev. However, whether in China or Japan, the other place in which we seriously work in the advent of magnetic levitation trains. For example, This is a technical and physical concern that takes place when a china about tame their biggest Maglev enters or leaves a tunnel. Consequently, Its high speed of movement creates sound shock waves due to the rapid compression of air. which has two consequences: a deafening noise and especially damage to the structure around the tunnels.
This phenomenon is not specific to magnetic levitation trains. it is also known on high -speed trains like our TGV, but it is significantly less significant given their smaller speed (in France the trains generally roll at 320 km/h, even if the absolute record is at 574.8 km/h).
Draw inspiration from silent pistols to advance technology – China about tame their biggest
As much as the solution implemented is the inspiration of Chinese. engineers that is surprised. To reduce the Boom tunnel. the Maglev’s development team imagined a very innovative solution: to build porous shock absorbers on the wall at the entrance and exit of the tunnel.
The porous structure of these 100 -meter -long shock absorbers. china about tame their biggest combined with porous coatings on the body of the tunnel, allows the compressed air to gradually escape before the train reaches the entrance to the tunnel, thus removing the “bang” caused by the displacement. Where did the engineers get this idea? In the operating mechanism of silent pistols. Thus the shock absorber on the structure of the tunnel acts as a silencer placed on the cannon of. a firearm.
The advances promised by the Chinese team would constitute a major technical advance which could further unlock the development of future Maglev trains with travel speeds of up to 1. 000 km/h.
This is in any case the objective of the “electromagnetic. maglev propulsion” division of China Aerospace Science and Industry Corporation (CASIC), led by Zhao Ming. For the moment. the group of engineers is based on simulations carried out on superordinators as well as tests on prototypes on a reduced china about tame their biggest scale. Other larger tests were also carried out at the end of 2024 in the Shanxi province where the train reached speeds close to the 1. 000 km/h, but there is no question of generalization of technology, or commercial development with the opening of the service to the public.
