High Thrust-Density Electrostaic Engines Project
<p>These issues are addressable by: increasing the thrust, power, and thrust-to-power ratio capability of EP systems; reducing the non-recurring engineering systems costs; and developing system architectures with performance characteristics that capture the broadest possible range of missions so that development & flight costs are amortized over multiple users. We believe these objectives can be achieved by developing the Next Generation Electric Propulsion Thruster (NGEPT); a GRC-patented modular EP device based on a new arrangement of relatively mature and proven technologies with the potential to yield revolutionary capabilities</p>
