Microvascular Systems

Bio-inspired Circulation

Microvascular systems mimic natural circulatory systems so that vehicles and other structures can adapt to changing environments. CRG’s microvascular networks are part of a larger vision that introduces bio-inspired engineering throughout high-performance material systems. These circulatory networks are integrated into structures and surfaces in order to transport engineered fluids through a vascular network, providing tailored performance and new design flexibility. Microvascular systems offer unparalleled control of system properties.

Bio-inspired Features

Circulatory systems embedded in structural materials can distribute engineered fluids in-flight to repair damage or trigger changes in structural properties. These integrated microvascular systems result in increased system survivability and performance.

Microvascular networks can be used as large-area heat exchangers at high altitudes. They require low pumping power and add minimal weight and no parasitic drag to the system when they replace existing heat rejection technologies. By adjusting the elastic modulus of a structure, the stiffness can be tailored locally or globally to increase the range of system capabilities. Microvascular circulation enables this type of adaptive aeroelasticity, which improves overall flight performance and flight control efficiency.
