Defense UAV flow control

AFC-1 active flow control for UAV agility.

AFC-1 is an active flow-control module designed to increase UAV maneuverability, transient stability, and auxiliary control authority with minimal mechanical complexity.

The system 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.

Product Summary

A low-cost control layer for UAV agility.

AFC-1 is Metadynamic's near-term UAV product platform. It is designed to give drones an additional electronic control input by actively shaping airflow, exhaust behavior, or boundary-layer conditions in real time.

Instead of replacing a drone's propulsion system, AFC-1 works alongside existing engines, fans, and aerodynamic surfaces. The system combines compact actuation hardware, embedded control electronics, sensor inputs, and Metadynamic's closed-source control software to improve stability and maneuverability at minimal integration cost.

The Problem

Small drones are becoming faster, but control systems are not keeping up.

High-speed UAVs, turbine drones, ducted-fan aircraft, and compact defense platforms face a common problem: agility depends on airflow that is often unstable, delayed, or mechanically expensive to control.

Traditional solutions can add weight, cost, and complexity:

mechanical thrust-vectoring nozzles
larger control surfaces
complex gimbal systems
heavier servos and linkages
higher drag airframe changes
expensive engine redesigns
slower response during rapid maneuvers

For many drones, the goal is not a completely new propulsion system. The goal is more control authority from the hardware already onboard.

The Solution

Add electronic flow authority without redesigning the aircraft.

AFC-1 adds a software-controlled active flow-control layer to existing UAV platforms. Depending on configuration, the module can be positioned near the exhaust, intake, duct, or aerodynamic surface.

The system is designed to generate small but fast corrections in flow behavior, giving the flight controller an additional way to stabilize or maneuver the aircraft.

exhaust plume trim
flow separation control
intake flow conditioning
yaw and pitch stabilization support
fast transient correction
reduced reliance on moving vectoring systems
closed-loop software control
low-cost modular integration

What AFC-1 Does

Four integration modes for practical UAV control authority.

01

Exhaust Trim

AFC-1 can be configured near the exhaust stream of a small turbine or ducted propulsion system to bias the plume slightly left, right, up, or down.

02

Flow Stabilization

The module can help stabilize flow during aggressive maneuvers, high-angle conditions, or transient throttle changes.

03

Intake Conditioning

Selected configurations may help reduce inlet distortion and improve stability for compact turbine or ducted-fan UAVs.

04

Boundary-Layer Control

AFC-1 may be adapted for aerodynamic surface testing where plasma or RF-based actuation influences boundary-layer behavior and delays flow separation.

MDCS Software

Closed-source control software for active flow authority.

AFC-1 uses Metadynamic Control Stack software to translate sensor input and flight-control intent into bounded actuation commands. The software layer is where response shaping, interlock handling, calibration maps, and test-run comparison live.

MDCS-FLOW

Flow-state estimation and operating-mode selection.

MDCS-CTRL

Low-latency actuation commands, interlocks, and response shaping.

MDCS-DIAG

Bench, tunnel, and flight-test data ingestion for run comparison.

MDCS-OPT

Search tools for stable actuation regions across throttle and attitude states.

Target Platforms

Built for fast validation on practical UAV hardware.

What It Is Not

Clear boundaries for a serious defense research product.

not a plasma-thrust propulsion system
not a finished flight-qualified product
not a replacement for flight controls
not a validated performance claim
not a weapon system

AFC-1 is positioned as an auxiliary control layer for validation and integration studies. Flight performance claims require measured bench, wind-tunnel, and controlled test data.
