Equipped on the Fujian shipElectromagnetic catapultIt has attracted a lot of attention, and many people are curious about its performance. After technical analysis, we found the Fujian shipElectromagnetic catapultperformance with the United StatesFordNoAircraft carriersofElectromagnetic catapultAt least flat, maybe even better. According to observations of the Fujian ship ejection ** and referencesFordNoAircraft carriersdata, we can preliminarily estimate the distance and ejection speed of the car on the Fujian ship.
Fujian shipDisplacementis more than 80,000 tons, the size of the United StatesFordnumbers are similar. The time for the ejected trolley to get from the deck to the surface of the water is about 2 seconds, and the distance from the point of landingAircraft carriersThe distance between the tail edges is aboutAircraft carriers125 times, that is, about 400 meters. At the same time, taking into account the air resistance, the trolley flies at a speed of more than 80 meters per second. Judging from the comparison chart, the volume of this trolley is comparable to the 4-axle crane next to it, and the estimated weight is also close to 30 40 tons. Therefore, we can deduce the Fujian shipElectromagnetic catapultThe ejection energy is more than 96 128mj.
In comparison to 2015, the United States was inFordNoAircraft carriersIn the electromagnetic ejection test, the ejection trolley weighed 36 tons, and its kinetic energy was also as high as 1152mj。If the Fujian ship is usedElectromagnetic catapultCatapult J-35 fighter, based on the calculation of the maximum take-off weight of 30 tons, theElectromagnetic catapultAt full power, the J-35 can accelerate to 90 meters and seconds (324 kilometers and hours). It is understood that the United StatesFordNoAircraft carriersEquippedElectromagnetic catapultThe maximum ejection energy is about 122mJ. Taking into account the error, we can speculate about the Fujian shipElectromagnetic catapultThe maximum ejection energy is at least as strong as that of the United StatesFordNoAircraft carriersElectromagnetic catapultFairly.
In addition to the comparison of performance, the stability of the electromagnetic catapult of the Fujian ship is also worth paying attention to. Compared to the United StatesFordNoAircraft carriersofElectromagnetic catapult, Fujian shipElectromagnetic catapultMore stability. U.S. ** Trump has saidFordlevelAircraft carriersonElectromagnetic catapultToo expensive and said to change it toSteam catapult。Trump's dissatisfaction with the electromagnetic catapult system stems from:FordNoAircraft carriersThe first generation of synthesis adoptedElectricityProblems with the system, resulting in:Electromagnetic catapultThe reliability is not good.
However, the Fujian ship adopted the second-generation synthesisElectricitysystem andElectromagnetic catapultbut with higher reliability. This stems from the Chinese research team's exchange of traditional medium voltageElectricityThe technology was abandoned, and a medium-voltage DC that was more suitable for the first class was adoptedElectricityTechnology. Ma WeimingAcademician as ChinaElectromagnetic catapultThe leader of the technology research and development of the project, on how to integrate with the second generationElectricityThe perfect fit of the system was thoroughly studied and finally successfully developedElectromagnetic catapult。The Fujian ship even in order to waitElectromagnetic catapultwithSteam catapultThe results of the comparative tests interrupted the construction work.
According toNavyMajor GeneralYin ZhuoIn an interview with CCTV, he said that China has conducted hundreds of electromagnetic ejection testsElectromagnetic catapultThe reliability and performance have been proven. Therefore, the stability of the electromagnetic catapult of the Fujian ship is much higher than that of the United StatesFordNoAircraft carriersofElectromagnetic catapult
To sum up, through technical analysis we can conclude: the Fujian shipElectromagnetic catapultThe performance and stability are comparable to or even exceed those of the United StatesFordNoAircraft carriersofElectromagnetic catapult。Fujian shipElectromagnetic catapultThe ejection energy is at least 96 128mJ, and the maximum ejection velocity is expected to exceed 90 m/s. In addition, the stability of the electromagnetic catapult of the Fujian ship is higher, and the reliability has been verified by many tests. , Fujian shipElectromagnetic catapultAnd not only China was shownAircraft carriersTechnological advances, tooChinese NavyOcean-going warfare provides enhanced capabilities.
