All continuous-combustion jet engines require a flame holder. A flame holder creates a low-speed Eddy in the engine to prevent the flame from being blown out. The design of the flame holder is an issue of balance between a stable eddy and Drag . The simplest design, often used in amateur projects, is the can-type flame holder, which consists of a Can covered in small holes. Much more effective is the H-gutter flame holder, which is shaped like a letter H with a curve facing and opposing the flow of air. Even more effective, however, is the V-gutter flame holder, which is shaped like a V with the point in the direction facing the flow of air. Some studies have suggested that adding a small amount of Base Bleed to a V-gutter helps reduce drag without reducing effectiveness. |
