计划安装于新一代 CVNX-1航母上的电磁飞机弹射系统(EMALS)是美国海军 CVNX 计划最重要的研究发展项目之一。新系统将取代在现役航母广泛采用的 C-13型蒸汽弹射器,与蒸汽弹射较比,EMALS 对舰上重量和舱室的要求减少50%,并可减少维修和人员的工作量、提高可靠性,有效减少全寿期费用。设计中的 EMALS 具有90余米长的直线电动机,并由旋转能量储存交流发电机通过脉宽调制(PWM)逆变器供应高频电力。直线电动机从逆变器获得平均电力后,
The EMAS, planned to be installed on a new generation of CVNX-1 aircraft carriers, is one of the most important R & D projects for the US Navy's CVNX program. The new system will replace the C-13 steam catapult, which is widely deployed on active duty carriers. Compared with steam ejection, EMALS reduces shipboard weight and cabin requirements by 50%, reducing maintenance and personnel workload and increasing reliability , Effectively reduce the cost of whole life. The design of the EMALS linear motor with more than 90 meters long, and the rotary energy storage alternator through the pulse width modulation (PWM) inverter supply high-frequency power. After the linear motor obtains the average power from the inverter,
