The Space Systems Lab of McDonnell Douglas developed several innovative techniques to perform the DELTA Star System thermal vacuum test. Test design constraints included an accelerated test schedule and an ambitious test plan focusing on cyclic absorbed orbital flux simulation. Test design and fabrication was completed in only 4 months, producing a 21 zone computer modeled refectorless lamp array system. Array zone control was based on discreet absorbed flux measurements, provided by adiabatic coupons conceived to eliminate the need for conventional radiometers. Test requirements, methodology, and test thermal model flight data correlation are presented.
