Is it safe to install electrical igniters in high power rocket motors before transport?

Installing electrical igniters in high power rocket motors before transport is not safe due to the potential risks involved. When an igniter is installed in a rocket motor, it introduces a risk of accidental ignition. Transporting rockets with igniters already in place can lead to situations where a circuit could be inadvertently completed, especially if there is static electricity or other sources of inadvertent ignition.

Electrical igniters are designed to ignite when the appropriate voltage is applied, and during transport, there could be many circumstances that might make it unsafe, such as bumping into objects, exposure to environmental factors, or unintended contacts with conductive materials. This is particularly crucial for high power rockets, where the motors contain a significant amount of propellant.

Ultimately, the safest practice is to leave igniters out of the motors until just before launch to ensure that there is no chance of an accidental ignition during transport. This reduces the likelihood of dangerous incidents occurring and helps ensure a safe launching environment.
