Pyrotechnic latch retraction mechanism for flying devices
The granted patent US12066277B1 describes a pyrotechnic latch retraction mechanism designed for devices with wings. The mechanism comprises a piston-cylinder assembly, an electric igniter assembly, and a guide assembly. The piston-cylinder assembly features a step-shaped cylinder and a piston pin that holds the wings in a folded position. It includes threaded and smooth holes to facilitate the flow of combustion gases generated by the electric igniter. The assembly is sealed with two rubber gaskets to ensure tightness, while a pin maintains the relative position of the piston pin and cylinder. The electric igniter, mounted on a bracket, ignites a pyrotechnic dose to produce gas flow, causing the piston pin to move. The guide assembly consists of a guide tube, housing, and bushing, which work together to support the movement of the piston pin.
Further claims detail the materials and specifications for various components of the mechanism. The piston pin and cylinder are made from non-reactive materials, such as stainless steel, with surface roughness not exceeding Ra1.25. The rubber gaskets are composed of high-grade heat-resistant rubber. The mounting bracket is designed for easy assembly and disassembly, and it can be made from treated steel or anodized aluminum. The pyrotechnic dose consists of potassium perchlorate and aluminum powder, with specific ingredient ratios tailored to the required pressure of the combustion gas. The guide tube and bushing are also specified to be made from stainless steel, with surface roughness limitations, ensuring optimal performance and durability of the latch retraction mechanism.
