Catapult Process of Different Catapult Systems for Carrier-Based Aircraft

The structureprinciplemathematical models and performance were studied for the two typical methodssteam catapult and Electromagnetic Aircraft Launch System(EMALS)for catapult launch of carrier based aircraft.The compositions of steam catapult and EMALS were analyzed.The functions of the different parts of the catapult systems were also discussed.According to the kinematical characteristics of steam catapult and EMALSthe mathematical models were establishedtheir nonlinear kinematical equations were deduced and the comparative analysis reslult was given.Simulations were made for the two catapult methods on the speeding stage of the aircraft.The main factors that have effect on catapult launch performance were analysed for different catapult methods by using the simulation result.Comparison of the two catapult launch systems was also made.
