Hybrid Regression Rate Sensor
We are currently looking at several ways to make an inexpensive regression rate sensor that we will be able to cast in place in the fuel grain.
Some Ideas we have had to this point are:
Printed plastic sheet sensor (Dec 04)
Carbon/lace sensor (Jun 04)
Solder w/discrete resistor sensor (Jun 04)
Vertically oriented regression ladder sensor (Jul 05)
