Laser tensile test sample holder

In combination with a system for the simultaneous laser, wind tunnel and tensile machine testing of flat plate test samples wherein the tensile machine is located to approximately align the test sample parallel to the flow from a wind tunnel nozzle;

• a test sample holder for maintaining substantial alignment of the test sample parallel to the wind tunnel flow, comprising:
• a frame member;
• a stationary sample alignment member secured to the frame member, upstream in the wind tunnel flow from the test sample;
• an adjustable sample alignment member secured to the frame member, downstream in the wind tunnel flow from the test sample;
• means for supporting said frame member on the tensile machine with the stationary alignment member and the adjustable alignment member aligned substantially parallel to the flow from the wind tunnel nozzle;
• means for positioning the test sample with respect to the stationary alignment member and the adjustable alignment member to provide a smooth flow from the wind tunnel across the stationary alignment member, the test sample and the adjustable alignment member.
