Analysis of EAW and ReComm Communication Schemes for Hypersonic Flight: Status Report 1
Abstract
We summarize progress in our analysis of proposed communication schemes for hypersonic vehicles in flight. Investigations into the electron-acoustic wave (EAW) communication scheme have yielded a dispersion analysis indicating that EAW modes can be generated and propagate in the plasma layer [D. V. Rose et al., Voss Sci. Rep. No. VSL-0737, Nov. 2007]. These modes can be coupled to electromagnetic waves at the plasma layer boundary for the assumption of a sharp density boundary. A detailed analysis of the wave transformation coefficients at this boundary layer has been completed [D. V. Rose et al., Voss Sci. Rep. No. VSL-0832, Dec. 2008]. Here we report on new particle-in-cell simulations of EAW generation and propagation in a two-temperature plasma. The simulation model is being developed to test the stability and the transformation efficiencies of the waves in plasma conditions anticipated for hypersonic vehicles in sustained upper atmospheric flight. In addition, we summarize progress in our analysis of the ReComm scheme [M. Keidar et al., J. Spacecraft and Rockets 45, 445 (2008)], focusing on extending our previous 1D computational model [C. Thoma and D. V. Rose, Voss Scientific Report No. VSL-0816, July 2008] to longer time and length scales.
