Pulse jets, commonly known as pulse detonation engines, are devices that generate thrust by periodically igniting a fuel-air mixture in a combustion chamber. There are several synonyms that are often used to describe these unique engines, including pulse detonation engines, pulse combustion engines, pulse-detonation combustor engines, and continuous detonation engines. Each of these synonyms represents a slightly different variation of the basic pulse jet design, but they all rely on the same basic principle of creating a series of explosions to generate thrust. Some pulse jets are designed for use in aircraft, while others are used in industrial applications such as pumping and power generation. Regardless of their specific application, pulse jets are remarkable engines that offer high levels of efficiency and performance, making them an attractive option for a wide range of uses.
