Closed-loop RF plasma control
Closed-loop RF plasma control for electric propulsion.
Metadynamic Aerospace Research develops software-defined RF plasma-control systems for studying plume collimation, momentum-flux modification, and thrust-vector modulation in electric propulsion.
Our first research platform, NRPC-1, investigates whether phase-controlled RF excitation can produce repeatable, measurable changes in a magnetized plasma plume under controlled bench-scale conditions.
NRPC-1 is a working research program. It is not a flight-qualified propulsion product and does not report validated performance claims.

Newest Product
AFC-1 active flow control for UAV agility.
AFC-1 is Metadynamic's near-term UAV product platform: an active flow-control module designed to increase maneuverability, transient stability, and auxiliary control authority with minimal mechanical complexity.
It is intended for rapid bench validation, turbine-drone integration, wind-tunnel testing, and defense UAV agility demonstrations.
AFC-1 does not make the drone fly by plasma thrust. It makes the drone easier to control.

What We Build
Integrated systems for RF-controlled plasma propulsion.
Metadynamic builds the research stack around RF-controlled plasma propulsion, from test articles and excitation hardware to diagnostics, measurement systems, simulation, and proprietary control software.
We do not claim reactionless propulsion or propellantless thrust. Our work is grounded in conventional momentum conservation and focused on improving how electric propulsion systems convert input power into useful directed exhaust momentum.
Core Technology
Nonlinear RF plume control.
Traditional electric propulsion systems generate thrust by accelerating plasma or ions into an exhaust plume. Real plumes are not perfectly directed. Energy can be lost through divergence, thermal spread, instability, poor coupling, and incomplete conversion into axial momentum.
Metadynamic is developing RF plume-control methods that use phase-controlled excitation to modify the behavior of a magnetized plasma plume.
The goal is to determine whether RF phase relationships can improve or modulate:
NRPC-1 Research Platform
Bench-scale validation for RF plasma-control physics.
NRPC-1 is Metadynamic's first internal research platform. It is designed to test whether multi-channel RF excitation can produce repeatable phase-dependent changes in a low-density magnetized plasma plume.
The system is built for controlled comparison between baseline, randomized-phase, non-phased RF, and phase-controlled RF operating modes.

View Research PaperResearch Question
Can plasma exhaust be actively shaped after generation?
NRPC-1 is not designed to prove a finished propulsion product. It is designed to answer a specific experimental question:
Can phase-controlled RF excitation measurably alter the momentum distribution, divergence, or vector behavior of a magnetized plasma plume at fixed mass flow, magnetic field, and input power?
A successful result would show repeatable plume-control effects that survive null testing and cannot be explained by total RF power alone.
MDCS Software
Metadynamic Control Stack.
MDCS is Metadynamic's proprietary closed-source software platform for RF plasma-control research. It is used to simulate, command, diagnose, and optimize plasma-control experiments.
MDCS-SIM
Simulation
Parameter sweep tools for estimating plasma operating regimes before test execution.
MDCS-CTRL

Real-time RF control, phase management, interlock handling, and operating-mode execution.
MDCS-DIAG
Diagnostics
Diagnostic ingestion, plume-data processing, run comparison, and artifact rejection.
MDCS-OPT
Optimization
Tools for identifying stable RF phase, frequency, and magnetic-field operating regions.
MDCS-API
Interface
External test-stand or future spacecraft command access without exposing waveform logic.
The hardware creates the plasma environment. MDCS determines how that environment is measured, controlled, and optimized.
Why It Matters
The control layer around plasma propulsion is becoming increasingly important.
Electric propulsion is already essential to modern spacecraft. But as satellites, deep-space platforms, and defense systems demand more precise maneuvering, the control layer around plasma propulsion becomes increasingly important.
Potential long-term applications include:
Technical Discipline
Measurement discipline before claims.
Metadynamic's research process is built around measurement discipline. Every claim must survive:
We prioritize falsifiable experiments over speculative claims.
Intellectual Property
Patent protection plus closed-source control software.
Patent focus
Trade-secret focus
For Partners
A bench-scale validation program for serious technical collaborators.
Metadynamic is seeking relationships with aerospace laboratories, university plasma groups, defense research organizations, and technical advisors in electric propulsion, RF systems, vacuum testing, and plasma diagnostics.
We are building toward a bench-scale validation program that can support patent filings, grant applications, prototype development, and future propulsion-system integration studies.
