A working prototype of a miniature 2 MHz a.c. driven, weakly-ionized plasma anemometer for measurements at hypersonic Mach numbers has been developed. This device uses a plasma discharge between two encapsulated electrodes as the primary sensing element. The discharge is driven by a low power (less than 5 Watt) a.c. source at voltages on the order of 350 Vr.m.s.at atmospheric pressure with electrode gaps of 0.076 mm (0.003 in.). The discharge has demonstrated sensitivity to mean and dynamic… CONTINUE READING
