The stressed lap is not ready. The actuator boards are complete. The boards must be assembled with the actuators and then the 104 actuators must each be calibrated on the test stand. These tests are being setup. Some engineering problems remain in the test setup.
Actuation being considered is either hexapods, unique slide system, or integral hydraulic.
Axial support will be either Whiffle tree or vacuum. The vacuum test was preformed by TIW, TIW consultants, Bill Kindred, Bill Omann, and J.T. Williams. The test is complete and was successful. The test was conducted under difficult outside summer desert conditions. At times the surface temperature of the vacuum head reached 140 degree fahrenheit.
