介绍一种新型的螺旋桨特性负载模拟装置，它是全数字控制的直流转矩伺服系统，采用转矩电流双闭环控制方式。

A new equipment for simulated the performance of propeller load is introduced in this paper, it's an all digital DC torque servo system using torque closed loop and current closed loop control.

在某种程度上，这是由于涡轮螺旋桨具有强健的力学特性，而部分原因是由于“空中拖拉机”的油箱有橡胶膜紧密围绕弹孔使得泄漏减缓。

In part, this is because of the robust mechanics of turboprops and in part because Air Tractor's fuel tanks have rubber membranes which close around bullet holes to slow leaks.
