The addition of these metals to energetic materials creates complications when they are reused as fuel. The main problem associated with the addition of metal is NO_x production. The MFC is working on modeling some of these processes to reduce these problems so that the metals in energetic material may be utilized as a fuel source.  

Aerosol Formation: Aerosol formation at hypersonic speeds represents a challenging research area. 

Aluminum Flakes: Aluminum flakes boost the thrust of rocket motors and present an interesting combustion challenge.
