Abstract:

The overall objective of the program is to develop innovative concepts for more efficient and reliable clutch plates for the JSF Fan Duct Clutch. Carbon-carbon composite clutch plates can meet a 1,500 engagement life requirement for a lift fan clutch, but this is at least two times less than the desired lifetime. The carbon-carbon composite also does not consistently provide the desired range of friction coefficients. A new, innovative clutch plate concept that reduces wear rate and higher overall friction coefficient is required to increase the service life of the clutch. The clutch engages at up to ~8500 rpm and the clutch plates must survive rotational speeds in excess of 10,000 rpm. The clutch plates are required to withstand a high shear load in transferring ~70,000 in-lb of torque. The required instantaneous dynamic friction coefficient is>0.1 with a desired mean static coefficient of ~0.2. In Phase I Allcomp proposes to evaluate and demonstrate the feasibility of innovative clutch material and design to provide long wear life and a high, stable friction coefficient. New classes of C-C and CMC composite materials will be developed aiming to achieve balanced structural, thermal and frictional performances for the JSF Fan Clutch application.
