Pyrotechnic 🧨 fasteners (also called an explosive bolt, or pyro) are commonly used as a space rocket detachment system. They are used to quickly and efficiently release a rocket from its launch vehicle, allowing it to begin its ascent into 🪐 space. Pyrotechnic bolts are typically made of a high-strength material, such as steel or titanium, and are designed to withstand the high temperatures and pressures of a space launch. They are also usually equipped with a ⏲ timer or other mechanism to ensure that they detonate at the correct time. Space rockets are subject to extreme forces during launch, so it is important that the pyrotechnic bolts detonate correctly and at the right time in order to ensure a safe and successful launch. If the bolts do not detonate 💥 correctly, the rocket could be damaged or even destroyed. Pyrotechnic bolts are an essential part of the space launch process and have been used successfully for many years. But Elon Musk's 🧑‍🚀 SpaceX has a different take on them by using pneumatic detaching mechanism for their Falcon 9 rocket. This technology is more advanced, reliable and safe as compared to the pyroteumatic bolts. Pneumatic system uses compressed gas to generate the force required for detachment. The gas is directed through a series of valves and chambers to create the required amount of ☄️ force. The system is also equipped with a safety valve to release the gas in case of an emergency. Pneumatic system has many advantages over pyrotechnic system. It is more reliable as there is no possibility of accidental detonation. It is also safer as the gas is released slowly and can be directed away from the rocket. Pneumatic system is also more precise and can be used to detach the rocket at a specific time.
