000014496 520__ $$2eng$$aPreliminary measurements on the modulation of a sonic flow have been conducted by increasing the temperature at a sonic throat with the help of a plasma discharge. For a perfect gas, the flow rate being proportional to the inverse of the square root of the temperature at a constant settling chamber pressure, the jet flow rate should be able to be varied. In view of flow control actuator design, the frequency is then no limited by any mechanical constraint. The discharge can be either continuous or pulsed at high frequencies. The influence of the settling chamber pressure and electrode gap distance have been investigated. For an aerodynamically steady actuation, the jet flow rate can be reduced down to 70% of its nominal value (30% of flow rate reduction), the best effectiveness being obtained with a dc discharge. However, better potential efficiency is expected with a high current pulse discharge.
