Abstract: A rotational angle sensor unit for determining a rotational angle between a rotor and a stator, having a housing which defines a housing volume. The rotor is rotatably mounted in the housing volume. A printed circuit board has the at least one stator secured thereto. An anti-rotation device with a main part and a plastic spring prevents a rotation of the housing relative to a stationary mounting body when the housing is positioned in a mounting volume of the mounting body. The plastic spring has a plastic spring inner face facing the main part and a plastic spring outer face facing away from the main part. The plastic spring has a wall thickness ranging between 1.8 mm and 2.5 mm between the plastic spring inner face and the plastic spring outer face. An anti-rotation device for a rotational angle sensor unit is also provided.

Abstract: A method for modeling a new design for electromagnetic effects includes identifying, with a model based system engineering tool, an area of interest in the new design where a lightning strike may occur. The new design includes structural features and electromagnetic features. The method further includes generating, with an electromagnetic effects solver tool and a structural solver tool, a design model for the area of interest in the new design, extracting design parameters from the design model, and generating a reduced order model by processing the design parameters, test results, and simulation results with a modeling tool. The reduced order model couples the structural features with the electromagnetic features. The test results are determined by tests of known designs. The simulation results are determined by simulations of known models. The method further includes storing the reduced order model in a storage medium that is readable by a statistical modeling tool.

Abstract: An assembly for electromagnetic interference (EMI) shielding to prevent incident radiation from penetrating through a gap to an interior of an aircraft includes an electromagnetic band gap (EBG) structure. The EBG structure has a patch-and-via array connected to a ground layer. The EMI shielding includes a conductive adhesive and is flexible for conforming attachment to curved aircraft surfaces. The shielding may be located on a deflector plate that is parallel to an adjacent aircraft surface, on the airframe surface opposite to the deflector plate, or in both locations. The assembly filters out penetrating electromagnetic energy and prevents highly resonant cavity mode build-ups of electromagnetic energy inside a nacelle or other enclosure effectively protecting electrical equipment in the interior.

A secondary suspension system is located on the frame and includes a first suspension assembly, which includes a first air spring and a first auxiliary spring positioned at the first side beam. The first air spring is positioned below and is arranged to be pressurized for supporting the body of the railway vehicle above the frame. The first auxiliary spring is fixed to an upper side of the first side beam underneath and spaced apart from the first air spring. The first suspension assembly further includes a first force-transmission mechanism configured to transmit forces exerted by the body on the first air spring to the frame via the first auxiliary spring.

Abstract: Gas-flammability sensing systems and methods may be used to determine the flammability of gas mixtures in measurement volumes such as a fuel tank (e.g., an aircraft fuel tank). Gas-flammability sensing systems include a test cell structured to receive a gas sample, a heater in thermal communication with the test cell, and a gas meter configured to measure a physical property of the gas sample within the test cell related to the combustion state of the gas sample. The heater is configured to heat the gas sample to an elevated temperature less than the autoignition temperature of the gas sample. Methods of determining the flammability of a gas sample include collecting the gas sample, heating the gas sample to the elevated temperature, measuring the physical property of the gas sample after heating, and determining the flammability of a gas sample based upon the measured physical property.
