METRIC FLIGHT / PROPULSION WHITE PAPER

Beyond the sail.
Into the engineering.

Six propulsion approaches. The energy and momentum behind them. The experiments that could tell us what deserves to be built.

Concept electric plasma engine, not built hardware

Beyond the Sail: Geometry, Energy and the Next Propulsion Experiments brings the propulsion program into one technical PDF. Written for engineers, researchers and decision-makers who want to understand the opportunity and the work still required.

  • Six non-sail mechanisms and their momentum pathways.
  • Magnetic-nozzle evidence, efficiency boundaries and derived performance.
  • Power, propellant and thermal calculations with explicit assumptions.
  • Proposed experiment specifications, controls and decision gates.
  • A worked spacecraft example and primary-source references.

Research synthesis and proposed tests, not a peer-reviewed paper or a report of a demonstrated Metric Flight engine.
