Popis:	Experiments are described which demonstrate the feasibility of degrading AMK in a single pass with a system consisting of a hydraulic fuel pump from a TF30 engine and several types of flow restrictors such as packed tubes or needle valves. The performance of the degraded AMK was evaluated with full-scale aircraft filters (JT8D and CF6), a T63 combustor and laboratory scale tests including filtration, ignition, and gel permeation chromatography. Rheological experiments indicated that while the shear viscosity of AMK increases above a critical shear rate, the magnitude of the shear viscosity is not large enough to explain the effectiveness of the FM-9 additive. However, it has been shown that, associated with the critical shear rate, AMK exhibits strong viscoelastic effects that are not evident at low shear rates or in flow through an orifice. (Author)
