LEAK TEST OF X-20A PRESSURIZED COMPARTMENTS
Abstract
The compartments in production for the Environmental Test Model were completed to a test configuration which eliminated all nonstructural items such as equipment support structure, foot well, ducts, internal equipment, wiring, and plumbing. Compartment penetrations were made in accordance with the designed flight configuration except that a reduced number of electrical penetrations were made. The inflatable seal system functional test of the pilot's hatch, the pilot's compartment equipment access door, and the equipment compartment access door verified that these systems would retain sufficient pressure to provide a satisfactory compartment seal. A proof pressure test of each compartment demonstrated the integrity of the structure. The actual leak rate of the pilot's compartment was found to be .025 pounds of air per minute, well within the design goal of 0.168 pounds of air per minute, and the actual leak rate of the equipment compartment was found to be 0.021 pounds of air per min., also well within the design goal of 0.100 pounds of air per minute.
