Investigadores de China afirman haber desarrollado un nuevo y poderoso Sistema Electromagn\u00e9tico de Lanzamiento de Aeronaves (EMALS) para su empleo en portaaviones. Este sistema de catapulta electromagn\u00e9tica es capaz de acelerar un avi\u00f3n de 30tn, de 0 a 70m\/s en solo 2.1 seg, El nuevo sistema es mucho m\u00e1s eficiente que los tradicionales en servicio, su infraestructura es m\u00e1s simple, requiere menos mantenimiento y su tiempo de recuperaci\u00f3n para la realizaci\u00f3n de sucesivos lanzamientos es inferior. Si bien EEUU es pionero en el desarrollo de EMALS y los tiene en servicio desde hace a\u00f1os, el rendimiento de los mismos no ha sido satisfactorio. El desarrollo presentado por el \u201cSchool of Mechanical and Energy Engineering at Beijing University of Technology\u201d afirma haber superado los problemas de sus antecesores.<\/p>\n
Chinese researchers have allegedly developed a new, powerful Electromagnetic Aircraft Launch System (EMALS) using technology found in electric vehicles.<\/p>\n
The catapult can launch a 30-tonne projectile from 0 to 230 feet\/s (0 to 70 m\/s) in around 2.1 seconds.<\/p>\n
Developed by a team of scientists and engineers in Beijing, the new system could slash the cost of aircraft carrier EMALS catapults.<\/p>\n
The\u00a0South China Morning Post (SCMP)<\/em>\u00a0reports that it can handle roughly twice the weight of China\u2019s most advanced stealth aircraft, the J-20.<\/p>\n \u201cThe new catapult system has a small footprint, simple structure, and is lightweight and does not require a complex power supply system,\u201d explained the researchers. The team, led by Ye Lezhi, is an associate professor with the School of Mechanical and Energy Engineering at Beijing University of Technology.<\/p>\n The new EMALS system was unveiled on February 27 in a peer-reviewed paper published in the Chinese academic journal\u00a0Acta Armamentarii<\/em>.<\/p>\n Better, more powerful EMALS<\/strong><\/p>\n Existing EMALS accelerate an aircraft using a long, straight track. Many electromagnetic coils are laid around the track to generate thrust for continuous acceleration as the plane passes.<\/p>\n The United States has equipped its state-of-the-art\u00a0Gerald Ford<\/em>-class<\/a>\u00a0aircraft carrier with four electromagnetic catapults, making it a pioneer in this technology.<\/p>\n \u201cHowever, since its commissioning, the supercarrier\u2019s electromagnetic catapult system has been experiencing various serious issues, including poor reliability, low efficiency, and even prolonged malfunctions,\u201d Ye\u2019s team wrote in the paper.<\/p>\n
