The EMALS energy-storage system design accommodates this by drawing power from the ship during its 45-second recharge period and storing the energy kinetically using the rotors of four disk alternators; the system then releases that energy (up
An Empirical Method for the Catapult Performance
However, these vehicles'' power to fly was limited by their energy storage capacity which restricted cylinder [8], even the performance of electromagnetic catapult [15][16]. Thus, the rareness of the launching speed analysis stimulated this empirical method of estimation, described in the following section.
