Command / MicroForce & AxialForce
Command Propulsion & Fluid Management Systems
Ultra-lightweight Type III construction and compact packaging for propulsion and fluid-management systems. MicroForce provides the diaphragm architecture; AxialForce piston technology is coming soon.
- Positive fluid control
- Compact composite construction
- Program-specific integration
Choose a MicroForce Platform
Command MicroForce and AxialForce are positioned for lightweight, cost-effective propulsion fluid management. Diaphragm and piston architectures support rapid, controlled delivery and positive fluid control in dynamic and zero-gravity environments. Confirm fluid compatibility and mission requirements for each configuration.
