Recently, FujianAircraft carriersThe electromagnetic catapult trolley has attracted widespread attention, and even CCTV has reported on it. Everybody's got this oneAircraft carriersequipped onElectromagnetic catapultThe performance is very interested. This article will provide a technical analysis of its ability to catapult.
According to the estimation of the electromagnetic catapult of the Fujian ship taken by netizens, the electromagnetic catapult energy of the Fujian ship is at least the same as that of the United StatesFordNoAircraft carriersof quite. Fujian ship withFordNoAircraft carriersare similar in sizeDisplacementAlso similar. According to the Fujian shipDisplacement, deck height and other parameters, it can be deduced that the time from the ejection of the deck to the contact with the water surface of the Fujian electromagnetic catapult trolley is about 2 seconds. By analyzing the ejection screenshot provided by CCTV, it can be deduced that the point where the car fell into the water is about 400 meters away from the edge of the tail of the Fujian ship and about 160 meters away from the front edge of the beveled deck of the Fujian ship. Taking into account factors such as air resistance, it can be estimated that the speed of the trolley flying out is more than 80 meters per second. It can be seen from this that the Fujian ship is equippedElectromagnetic catapultThe ejection energy reaches at least 96-128MJ, which is equivalent to the United StatesFordNoAircraft carriersofElectromagnetic catapult
Despite the HokkienAircraft carriersElectromagnetic catapultThe exact weight is unknown, but dozens of splashes from the scenem highJudging from the splash, this little car is definitely not light. As can be seen from the **, the volume of the trolley is comparable to the four-axle crane next to it. It is known that the dead weight of a four-axle crane of this size is about 30-40 tons. Even if it is estimated according to the ejection speed of 80 meters and seconds, the FujianAircraft carriersEquippedElectromagnetic catapultThe ejection kinetic energy is also as high as 96-128MJ. FujianAircraft carriersElectromagnetic catapultPerformance over the United StatesFordNoAircraft carriersCauses.
It is known that in June 2015, the United StatesNavyInFordNoAircraft carrierscarried onElectromagnetic catapultThe test of the ejection trolley, which weighed 36 tons, was successfully ejected into the sea. And the FujianAircraft carriersadoptedElectromagnetic catapultThe performance is more advanced. Take, for example, the J-30 fighter with a maximum take-off weight of 35 tonsElectromagnetic catapultAt full power, it can be accelerated to 90 m/s (324 km/h). Presumably, the FujianAircraft carriersofElectromagnetic catapultThe maximum ejection energy is at least the same as that of the United StatesFordNoAircraft carriersofElectromagnetic catapultFairly. Judging from the comparison of other parameters, FujianAircraft carriersofElectromagnetic catapultPerformance could be even better.
U.S. ** Trump was rightFordlevelAircraft carriersonElectromagnetic catapultexpressed dissatisfaction, believing that it was expensive and unreliable, and even joked that only Einstein could understand how to operate an electromagnetic catapult device. Actually,FordNoAircraft carriersofElectromagnetic catapultThere are real problems with reliability, and even the United States ** is not satisfied. This is mainly because:FordNoAircraft carriersThe first generation of synthesis adoptedElectricityThere is a problem with the system itself, whileElectromagnetic catapultJust one of them. On the contrary, the FujianAircraft carriersof the second generation of the synthesisElectricityThe system adopts a more advanced medium voltage DCElectricitytechnology, with higher reliability. FujianAircraft carriersofElectromagnetic catapultIntegrated with the second generationElectricityThe system is perfectly matched and has high stability.
Through the Fujian numberAircraft carriersonElectromagnetic catapultA technical analysis reveals how powerful its ejection capability is. Through with the United StatesFordNoAircraft carriersIn comparison, the electromagnetic ejection energy of the Fujian ship is at least comparable to that of the United StatesFordNoAircraft carriersQuite, maybe even better. FujianAircraft carriersThe adoption of the second generation of synthesisElectricityThe system makes itsElectromagnetic catapultIt has higher reliability and stability. FujianAircraft carriersElectromagnetic catapultThe performance is forAircraft carriers's combat capabilities have a significant impact and can provide it with greater protectionCarrier-based aircraftand the capabilities of UAVs. This will further elevateChinese Navy, so that it can perform its tasks more effectively in future naval operations.
