Survivability Technical Committee

This discussion is a collaborative space to share research ideas in a area of Aircraft/Spacecraft Survivability. Feel free to post any research ideas you have or offer feedback and collaboration opportunities for other people's ideas. Come back often to check for new topics.

Community Guidelines:

1. Be kind and courteous to one another. 
2. Do not share controlled or proprietary information in this forum. 
3. Do not plagiarize or steal research. This is meant to build community and encourage collaboration. Do not take ideas or work presented here and try to complete it yourself, separate from the original poster, in order to beat them to the solution.

I fully support Adam's thoughts on liquid spurt. This was actually also one of the recommendations for future work identified in a review paper on HRAM, which was recently accepted for publication:
