Auto Distress Beacons 自动遇险信标

An auto distress beacon for an airplane or rocket can be made using transistors to crate a simple astable multivibrator. Very similar to the aviation safety light control circuit, the auto distress beacon explores ideas and concepts that are related to real world applications of electrical theory. With both visual and audible indicators, this circuit is a great addition to a high school aviation or rocketry project.

飞机或火箭的自动遇险信标可以用晶体管封装成一个简单的多谐振荡器。与航空安全灯控制电路非常相似，自动遇险信标探索与电学理论实际应用相关的想法和概念。该电路具有可视和可听指示器，是高中航空或火箭项目的重要补充。

Using a similar design to the aviation control circuit, an auto distress beacon creates a visual and audible tone that can be used to locate a crashed aircraft or rocket.
使用与航空控制电路类似的设计，自动遇险信标可产生可视和可听的音调，用于定位坠毁的飞机或火箭。
