## 物理特性

### 能量密度

${\displaystyle {\frac {E}{m}}=K\left({\frac {\sigma }{\rho }}\right)}$,

${\displaystyle E}$ - 轉子的動能[J]
${\displaystyle m}$ - 轉子的質量[kg]
${\displaystyle K}$ - 轉子的幾何形狀係數[無量綱]
${\displaystyle \sigma }$ - 材料的拉伸強度[Pa]
${\displaystyle \rho }$ - 材料的密度[kg/m^3]

## 应用

### 脉冲电源

Flywheel Energy Storage Systems (FESS) are found in a variety of applications ranging from grid-connected energy management to uninterruptible power supplies. With the progress of technology, there is fast renovation involved in FESS application. Examples include high power weapons, aircraft powertrains and shipboard power systems, where the system requires a very high-power for a short period in order of a few seconds and even milliseconds.Compensated pulsed alternator (compulsator) is one of the most popular choices of pulsed power supplies for fusion reactors, high-power pulsed lasers, and hypervelocity electromagnetic launchers because of its high energy density and power density, which is designed for FESS[5].
