I was wondering if you could elaborate on exactly what it is that you're trying to do? In your initial description, which is not very detailed, I fail to see what you want to find out that an engineer doesn't already know? There is an element of basic physics involved, but the main thing is that this is something that you simply have to know. Park designers do this on a daily basis, and if the jumps cause accidents to the point where it is the jump and not the riders fault, then the person who build it is not a good park designer, or he wasn't paying attention when he build it.
My point is that most major parks already build and maintain jumps and other features that are as safe as possible, simply because they learned by trial and error, have a knowledge of basic physics, or most likely a combination of both. As for myself, I can always tell if something is going to work or not, as I test it and have my co workers test it as we are building and perfecting it. We would never open something that isn't safe to the public. This is what being a park designer and a shaper means, working together to build challenging and safe features. I just don't see a need for what I think it is that you are offering (again, your description is vague). Sure there are tons of parks out there with super dangerous features, but that has to do with the training of the staff, their experience, the attitude of the resort and so on. Most park designers that know what they are doing would never open something unsafe to the public, and already know how to build safe features.
That got a bit long winded, in short I have one question: What is it that you are trying to develop/offer, and is there a need for it?
