Abstract
A radiofrequency antenna is adapted to be mounted on a spacecraft. The radiofrequency antenna includes four helical strands of a super elastic shape memory alloy and is configured to move from a deployed configuration to a constrained stacking configuration and to return autonomously to the deployed configuration.
Claims19
A radio frequency antenna adapted to be mounted on a space vehicle, the antenna comprising:
- four helical strands of super elastic shape memory alloy and configured to pass from a deployed configuration to a constrained stacking configuration and to return to a self-deployed configuration, the super elastic shape memory alloy having the ability to return to an initial shape without having to be heated so long as the super elastic shape memory alloy remains within a temperature range and does not exceed a deformation rate, wherein the temperature range includes −150° C.
A radio frequency antenna adapted to be mounted on a space vehicle, the antenna comprising:
- four helical strands of super elastic shape memory alloy and being configured to pass from a deployed configuration to a constrained stacking configuration and to return to a self-deployed configuration in response to a securing and a releasing of a mechanical constraint, so long as the super elastic shape memory alloy remains within a temperature range, wherein the temperature range includes −150° C.
A radio frequency antenna adapted to be mounted on a space vehicle, the antenna comprising:
- four helical strands of super elastic shape memory alloy and being configured to pass from a deployed configuration to a constrained stacking configuration and to linearly return to a self-deployed configuration, so long as the super elastic shape memory alloy remains within a temperature range, wherein the temperature range includes −150° C.
