Final answer:
Two non-electric detonating delay systems are pyrotechnic delay assemblies, which use a burnable material for timing, and mechanical delay devices that utilize gears or springs for a timed delay.
Step-by-step explanation:
Two kinds of non-electric detonating delay systems are pyrotechnic delay assemblies and mechanical delay devices. Pyrotechnic delay assemblies utilize a combustible material that burns at a predictable rate to create a time delay before initiation. Mechanical delay devices, on the other hand, employ physical mechanisms, such as gears or springs, to produce a timed delay.
These delay systems are used in various applications, from commercial blasting to military ordinance, providing a crucial timing function that allows for safe and controlled detonations. They are essential in scenarios where precise timing is necessary but the use of electronic devices might be impractical or dangerous due to environmental conditions or the risk of electronic interference.
