A transformer rectifier unit (TRU) is an electronic device that contains thyristors or diodes within the same tank and aids in voltage regulation. Additionally, transformer rectifiers are used to convert alternating current (AC) into direct current (DC) through a process called rectification. As transformer rectifiers are complex instruments, this blog will cover some of their basic features, working principles, and various types.

A rotary-wing aircraft, or rotorcraft, is a type of heavier-than-air aircraft that features rotary wings or blades. Unlike typical fixed-wing aircraft, rotary-wing aircraft produce lift through the means of rotating their wings or blades around a vertical mast. Depending on one’s particular needs or application, there are a few common types of rotorcraft one may use, including those such as helicopters, autogyros, and gyrodynes. In this blog, we will provide an overview of the primary rotorcraft types, discussing the configurations and capabilities of each so that you may best understand them.

Aircraft piston engines, also referred to as reciprocating engines, are those that utilize one or more reciprocating pistons for the means of transforming pressure into a rotating motion. Coming in a variety of forms, piston engines have long served aircraft since the inception of powered flight. Despite their long history, piston engines can still be found on a number of modern models, utilizing their standard operations to drive propeller assemblies for the means of flight. In this blog, we will describe the basic functionality of piston aircraft engine types, allowing you to understand how they work.
