Good morning, my name is Alan Offer and I want to build a two stage rocket using Hot stage Separation to deploy. My design criteria is that I need to build a separation mechanism for two stage having a minimum diameter and a 98mm motor. I made a CAD (see the figure) of how the separation mechanism will work. First the sustainer stage will be ignited using the booster flight computer that you see on the bottom of the bulkhead ( two ignition wires will go up the upper stage, one from a flight computer made by me and the other is a Blue Raven from Featherweight altimeters). Then the nozzle of the Pro 98 N1100 will be insert into the conical support made in aluminium. Finally I will drill 6 vent holes so that the pressure will be evacuated. My question is, in order to ignite the second stage I need the first stage avionic, should I put sheer pins to prevent it to stage prematurely? Or do you think is ok ? If I have to put sheer pins, where should I place them.
Thank you and have a great day,
