Eric Hettinger General Goals: Once the current scale model’s parameters are analyzed and an appropriate optimized system is functioning (sufficient regression rate, chamber pressure, etc) to our satisfaction, looking for some type of sponsorship or grant possibilities would help with the initial costs of the liquid motor design. I’m not sure if we have done enough experimental tests to apply for a grant of some kind, but I think it would help speed up the construction process, so time is not spent on trying to rig things together with cheap parts. Developing a paraffin technology that produces a useful and reliable source of thrust is very important. If the technology is refined enough, the sale of scaled models may help fund the project, as long it doesn’t side track us. Safely handling liquid oxygen and static test firing of such a large motor is a serious undertaking. (insurance needed?) Implementing off the shelf parts seems realistic for the budget and time required (from ebay), but a more reliable source of parts would be more beneficial to keep on schedule. Keeping things simple is definitely important, so analyzing different influential parameters is possible. Being able to use economical instrumentation in refining oxygen/fuel mix, flow rates, regression, etc is important. Throttling and active guidance appears to be a logical step once the basic design has been proven functional and is reasonably efficient. Altitude is a consideration in the design looking at the big picture. After the majority of the issues such as sagging effect of larger fuel grains are solved, things can always be scaled up if the system is initially well designed and flexible.
