Hello all,

I want to build the rocket that has 2 M class motor with stage seperation. Do you have any ideas about non pyro staging systems? CO2 systems with servo are not suitable.

Thanks in advance!
John

2cnd stage ignition as a backup to drag sep works well.

Thank you for the comments! Unfortunately, drag seperation can't be used as well, do you have any more ideas? Like spring or locking mechanisms etc.

I have a university team that is working on something that might be termed a spring or locking mechanism. I can have them contact you if they choose to (but I suspect they will not want to share it). PM me your contact information.

Maybe some variation of the Marman clamp with a solenoid activated pull pin or something.

I have developed a variety of latching systems for rocket applications (pyroless deployment, parachute retention, high pressure gas hosing release etc). If you can provide details on any size/mass constraints or max load requirements I'll try and assist where I can.
