Labscale Model -If we can test in MECH's combustion chamber, we will build at least 3 SIMPLE SMALL models to determine the fuel regression rate with NOX. Will also give us a chance to practise fuel making and BASIC insturmentation. -There was a discusion that if the model is small enough .... perhaps we could just test it ...... (I'll leave the rest implied) Oxidizer -Will it be gaseous or liquid? PDR -Let's do it a week early. ie in 2 weeks, not 3.
