Abstract: An optical sensor diagnostic system includes a tunable narrow wavelength-band source (9) which provides a variable wavelength light (44) into an optical fiber (32, 52). Reflective sensors (54, 58), such as Bragg gratings, are disposed along the fiber (52) in the path of the variable light (44). The sensors (54, 58) transmit light (56, 60) having a minimum transmission wavelength which varies due to a perturbation, such as strain, imposed thereon. A tuner control circuit (42) drives the tunable light source (9) to cause the source light (44) to scan across a predetermined wavelength range to illuminate each sensor at its minimum transmission wavelength. The power of the transmitted light is converted to an electrical signal by a detector (64) and monitored by a signal processor (68) which detects drops in transmitted power level and provides output signals on lines (71) indicative of the perturbation for each sensor. The system may be configured in open loop mode to measure static strains, or closed loop mode to track static strains and measure dynamic strains. Also, the system may be used in a Fabry-Perot configuration to provide a very sensitive strain detection system. Further, the system may be configured in reflection or transmission mode.

Abstract: A nacelle and mounting arrangement for a high bypass ratio ducted fan aircraft engine mounted external to the aircraft main structure is disclosed. The nacelle and mounting arrangement isolate the engine from the adverse effects of certain aerodynamic forces acting on the nacelle by transferring substantially all of those forces directly from the nacelle to the aircraft and transferring substantially none of those forces to the engine. Various arrangements of the nacelle components which facilitate engine removal while avoiding the placement of nacelle component interfaces in highly stressed regions of the nacelle are also disclosed.

Abstract: A lightweight braided metallic shielding is applied to wiring harnesses to protect against lightning strikes and electromagnetic interference (EMI). The braided shielding has an open braid construction which may be as much as 40% lighter in weight and which provides better electromagnetic shielding than conventional braided shielding. The decrease in weight is achieved by utilizing a braid carrier application angle, as measured from the axis of the wire harness, which is as small as about eighteen degrees, so as to produce a braided shield that has as few as four picks per inch. The ensuing braided shield is very flexible and results in a degree of wire harness coverage which may be as low as about 60 %, but which exhibits low electrical resistance which contributes significantly to lightning protection and EMI shielding.

Abstract: An air cycle environmental control system for an aircraft cabin is disclosed which utilizes cabin exhaust air (200) to power a first stage turbine (108). This provides a significant increase in compressor power which increases the turbine cooling available in a stage turbine (112). The ram air consumption is also reduced due to the cabin exhaust air being ported to the ram air inlet where it merges with the ram air prior to cooling of the bleed air supply in a dual heat exchanger (132).

Abstract: A DC-biased axial magnetic bearing includes a rotating member (50) (or shaft) having a radially extending tab (or support) (52) located between a pair of teeth (62, 64) of a C-shaped control member (60). A permanent magnet (68) provides a DC magnetic field (82) which travels through an overhanging arm (70) and provides a DC bias attractive force between a surface (72) of the arm (70) and an upper surface (74) of the shaft (50) which levitates the shaft (50) such that the tab (52) is equally spaced between the surfaces (62, 64). Coils are wrapped circumferentially around the shaft (50) within the C-shaped control member (60) and current through the coils provides electromagnetic trim control of the position of the tab (52) between the surfaces (62, 64) in response to changes in axial position of the shaft (50) indicated by position sensors (96). The bearing may also be used in horizontal applications, e.g., in an engine.

Abstract: A method for increasing the vertical scan rate in a video scanning system, for example a reflector-based motion measurement system. According to the method, a certain plurality of scan lines is pre-selected from among the full number of horizontal lines constitituting a TV field. The period between successive video scans is greatly reduced by reading only those lines which were pre-selected, and skipping the remainder. The results of each reading of a horizontal scan line are used to pre-select the horizontal scan lines for the next vertical scan.

Abstract: A fan blade containment assembly includes a flow surface forward of the fan blades that is defined by the inner surface of the case. Various construction details are developed that provide an axially and circumferentially continuous flow surface forward of the fan blades. The continuity and uniformity eliminates structural discontinuities that increase noise levels associated with the engine. In a particular embodiment, the case is formed from an isogrid structure, a plurality of cloth wraps wound under tension around the case, and a plurality of acoustic panels downstream of the fan blades. The flow surface forward of the fan blades is provided by machining the inner surface of the case to the desired shape.
