Abstract:

An RD Program was conducted to develop and demonstrate Dynamic Seal Designs Rod and Piston Seals for Advanced Aircraft 55.2 MPa 8,000 psi hydraulic systems using nonflammable CTFE fluid over a temperature range of -54C -65F to 135C 275F. Two sizes of each seal design were tested in simplex, unbalanced flight type actuators using dual unvented rod seals under simulated flight control surface air loads. The rod seal designs were tested in MIL-G-5514 grooves and clearances. Several elastomers energized and spring energized plastic rod seal designs backed with modulus plastic back-up rings completed successfully the 12,200,000-cycle test. None of the tested piston seal designs completed the test. Keywords Elastomers Hydraulic fluid High pressure seals Nonflammable fluid Sealing systems Back up rings Dynamic testing.
