That’s an ad hoc genius idea.

My concern would be that we have two different burst failure problems: the low pressure side had to fail toward low pressure, the high pressure side has to fight the pressure on the other side of that disc.  The charge required for the latter is obviously greater than that required for the former.  And in both cases we are venting hot gas into our system....

It has another possible benefit - the nitrocellulose is at some controllable pressure. Nitrocellulose can fail to ignite in vacuum.

But I still think a hot wire melting a plastic diaphragm would be simpler.
