Airbags are in addition to chutes to further reduce landing impact.

Kenat-That was my original thought process that it wouldn't be too difficult to implement the stored gas approach. Discussions with certain individuals have steered me in other directions but I haven't heard anyone say that its not possible-just problematic from experiences. Some of these...

Mike-I like the thought process. Unfortunately, I'm only on contract to build a few initial test assets with the possibility of much larger quantities down the line. It's a huge gamble and one my employer will most likely not even consider.

Thanks for the replies. They are landing airbags. Not a student just not my area of expertise as I stated. As for scale, looking to inflate 2 bags ~35 cu ft each. Storage space is not really an issue. I have a large compartment to work with and calcs show I have enough margin for stored gas...

Thanks for the reply Mike. I have pursued the pyrotechnic approach. Unfortunately the price I have been quoted is astronomical and a nonstarter. Lots of NRE in addition to high refurb cost. If price were not an issue I think this design is a no brainer. However, complications also arise from the...

Currently designing a system that requires inflating multiple airbags during end of flight recovery. The current approach being taken is to use stored gas within a high pressure cylinder and a solenoid valve to control flow. A pressure switch would monitor the pressure level and activate the...

WKTaylor-Thank you. That's perfect. Tbuelna-I've used them in applications that are near sensitive electronics, where conduction would be problematic. I've also used them as frangible fasteners. drawoh-See above for typical uses. It's typical of my company to use standard parts for a system...

Can someone point me to an engineering standard for nylon screws?
