A variable volume test apparatus (10) utilizes an adjustable ceiling (28) to vary the volume of the chamber (2). The ceiling (18) is sealed in its new position through the use of an inflatable bladder (26). Adjustable vents (58) are positioned in the ceiling (18) and walls (24) to direct fluid flow into the chamber (20). Floating joints (84) within the chamber doors (16) allow the door' inner walls (80) to contract or expand relative to the outer walls (84) without creating a corresponding stress on the outer walls (84) or the rivets (86). As a safety feature, the door locks (150) are computer controlled so that the doors (16) cannot be unlocked from the outside until the test chamber (20) reaches an operator safe condition. One door (16), however, has an override button (150) that allows the operator to open the door (16) from the inside of the test chamber (20). A retractable, vibration table (200) with shock absorbers (138,140) and hand brake (128) is also provided.
