商品发动机无论大小,目前推荐的点火方式全都是有线电点火。

美国火箭协会大功率火箭安全规定
4.Ignition System. I will launch my rockets with an electrical launch system, and with electrical motor igniters that are installed in the motor only after my rocket is at the launch pad or in a designated prepping area. My launch system will have a safety interlock that is in series with the launch switch that is not installed until my rocket is ready for launch, and will use a launch switch that returns to the "off" position when released. If my rocket has onboard ignition systems for motors or recovery devices, these will have safety interlocks that interrupt the current path until the rocket is at the launch pad.
使用有线电点火。
火箭在发射台到位后再插入点火头。
点火系统应有安全连锁装置与点火开关串联,直到准备点火前安装。
使用松开后回到OFF状态的按钮开关作为点火开关。
箭载点火系统的点火回路里要有安全连锁装置断开电路,直到火箭在发射台到位。
5.Misfires. If my rocket does not launch when I press the button of my electrical launch system, I will remove the launcher's safety interlock or disconnect its battery, and will wait 60 seconds after the last launch attempt before allowing anyone to approach the rocket.
如果点火失败,去掉点火系统的安全连锁装置或电池
在最后一次点火尝试后等待60秒再接近火箭
XXXXunch Safety. I will use a 5-second countdown before launch. I will ensure that no person is closer to the launch pad than allowed by the accompanying Minimum Distance Table, and that a means is available to warn participants and spectators in the event of a problem. I will check the stability of my rocket before flight and will not fly it if it cannot be determined to be stable. 倒数5秒发射
确认没有人进入警戒区域(见安全距离表),并警告参与人员和观众
检查火箭飞行稳定性,如果不能确定稳定则不发射
