Currently the United States space program is recognized as the world leader in providing access to space. However, in order to maintain this position, it will be necessary to reduce the very high cost of reaching low Earth orbit by using single stage or two stage to orbit vehicles. Some components of these vehicles have exceptionally high heat loads and require additional cooling capacity, which can be accommodated by utilizing the additional fuel heat sink capacity available from endothermic cracking reactions. Unfortunately, cracking reactions lead to coke deposition in the heat exchanger, which can be a potentially serious problem if it is allowed to accumulate. Therefore in this Phase I proposal, TDA Research, Inc. (TDA) will develop methods to remove the coke from the heat exchanger flow path. Previously, several different coke formation mechanisms were though to occur during cracking and the selection of an appropriate method to remove the coke would depend on the mechanism responsible. However, as a result of previous work, we have identified the mechanism primarily responsible for coke deposition with JP-7 and JP-8. Thus, the methods we develop in this SBIR Phase I proposal have a high probability of success.
