Patent ID: 11912078
Assignee: UNITED STATES GOVERNMENT ADMINISTRATOR OF NASA
Field: Transport (Mechanical engineering)
Classification: CPC B  C | IPC B  C

Claim 9:
10. A non-pneumatic tire comprising:
a tube comprising:
a first set of wires that comprises a loop of a cross section of the tire along the axis of the tube; and
a second set of wires that forms an interlaced mesh along the surface of the tube;
wherein the tube is conformed into a torus shape; and
wherein a selected number of wires of the first set and the second set comprise a shape memory alloy (SMA) having an austenite crystal structure in an ambient condition, and during the application of an externally applied force upon the SMA, the austenite crystal structure of the SMA reorients to a martensitic crystal structure to minimize internal strain energy and decrease local stiffness to accommodate load and deflection of the SMA, and wherein an applied level of torsion to the tube yields a selected set of tire parameters.
