I'm not quite sure where the best place to ask this is so I thought I would start here. Anyway, I'm a member of an undergrad engineering research team. We are trying to figure out if there are any companies that might make some type of a prefabricated test stand or platform for experiments. We are looking for something that is light and portable because our project is through the NASA's microgravity university and will be performed in simulated microgravity aboard an airplane. The limitations are 24"x24"x60" and 300 lbs. We aren't completely sure what we're looking for but again, I thought this wouldn't be bad spot to start asking around. If you aren't aware of any actual platform, are there any materials that work very well for making a light, portable experimental platform? Cost isn't a huge concern right now but of course, we're still on a budget. Again, not quite sure what I'm looking for so any info you have would be much appreciated. Thanks!
