Component Improvement Program for Aircraft Brake Piston Seals.
Abstract
Hydraulic fluid leakage in aircraft brakes has long been a problem for the Air Force. This leakage commonly occurs when the equipment is operated in a low temperature environment. In some cases, the leakage problem was resolved by using special nonstandard 'O' ring seals at a higher cost. Consequently, it is desirable to determine if a revision to the standard gland dimensions will improve cold temperature performance of MS-28775 series 'O' ring seals. The primary purpose of this investigation was to determine optimum gland dimensions for use with existing MS-28775 'O' ring packings for aircraft brake dynamic seals. A secondary objective was to evaluate new materials for seals. (Author)
