Characterizing the Dynamic Behavior of Novel Energetic Materials for Space Propulsion
Motivation
- To develop a commercially viable method of measuring burning surface admittances of high-energy-density solid propellants at high frequencies and pressures
Approach
- Only device that directly measures both components of acoustic admittance
- Magnetic flowmeter burner combines several techniques:
- Toothed wheel (A) provides variable-frequency interruption of nozzle flow
- Pressure tap (B) above burning surface grain measures pressure oscillation
- Magnet (C) and perpendicular electrodes (D) measure velocity oscillation
- Approach is unique to Micci’s lab at PSU
