摘要： An example method for determining space availability in an aircraft includes receiving outputs from a plurality of laser sensors positioned in a baggage container at a first wall and a second wall, and the first wall and the second wall face each other. The plurality of laser sensors emit signals within the baggage container and detect reflected responses to generate the outputs. The example method also includes receiving images from a camera positioned on a third wall of the baggage container, wherein the third wall differs from the first wall and the second wall, mapping contents of the baggage container based on the outputs from the plurality of laser sensors, based on said mapping, outputting data indicative of occupied space in the baggage container, and associating the images from the camera with the contents of the baggage container.

摘要： A freeplay measurement tool is disclosed. The freeplay measurement tool comprises a first measuring device configured to be removably coupled to a first structure and a second measuring device configured to be removably coupled to a second structure. The first structure and the second structure are connected via a joint. The freeplay measurement tool also comprises at least one load cell and a loading sling. The loading sling comprises a spreader bar, a first retention member, fixed to a forward end of the spreader bar and the load cell, a second retention member, fixed to an aft end of the spreader bar and the load cell, and at least one loading pad coupled to and extending from the spreader bar. When the first measuring device and the second measuring device are coupled to the first structure and the second structure, respectively, the spreader bar is positionable adjacent to a loading surface of the second structure so that the at least one loading pad applies a predetermined external load only to the loading surface of the second structure.

摘要： Systems and methods for backlash measurement and monitoring are disclosed for an actuator having a motor end and an output end. The method may include: driving the motor end of the actuator to one endpoint; measuring, using a first sensor, a motor-end initial position value associated with the motor end; measuring, using a second sensor, an output-end initial position value associated with the output end; driving the motor end of the actuator to another endpoint; measuring a motor-end final position value using the first sensor and an output-end final position value using the second sensor; determining a backlash value based on the motor-end initial position value, output-end initial position value, motor-end final position value, and output-end final position value; generating a signal based on comparing the backlash value to a predetermined threshold; and displaying a notification indicative of an operational condition of the actuator based on the signal.

摘要： A multi-modal multi-objective testing data generation method based on topology adaptive resonance theory is disclosed. The method considers that that the test aircraft under what kind of external disturbance or its own system fault conditions will be close to multiple index thresholds of unreliable or unsafe state at the same time as a black box optimization testing problem. The testing data is generated through optimization algorithms to test the aircraft state under different disturbance conditions. This type of black box optimization problem belongs to multi-modal multi-objective optimization problems. The testing problem can be solved using a multi-modal multi-objective particle swarm optimization algorithm based on adaptive resonance topology network. The external disturbance variable parameter combination encountered by the aircraft is regarded as the particle position, and the optimal parameter combination is found by iteratively updating the particle position.

摘要： Processes for determining carbon dioxide emission impact. In one process, a carbon dioxide emission impact is determined for each stage of a multi-stage trip. A traveler may make adjustments to the trip to offset the carbon dioxide emission impact of the entire trip and achieve a desired sustainability level for the trip. In another process, that may be used in the first process, the carbon dioxide emission impact for a vehicle is determined based on the entire life span of the vehicle, including a carbon dioxide emission impact for a production stage, a carbon dioxide emission impact for a usage stage, and a carbon dioxide emission impact for an end of life stage.

摘要： A method of testing an aircraft landing gear is disclosed including: a) generating a test signal with the first tachometer, wherein the first wheel is not rotating during the generation of the test signal; b) receiving the test signal via one of the tachometer output lines; c) issuing a braking command in response to the receipt of the test signal, wherein the braking command is issued via the braking command line which is associated with the one of the tachometer output lines; and d) monitoring a response of the first or second braking system to the braking command to test for a cross-connection between the first and second braking systems. The landing gear includes first and second wheels; a first braking system having a first tachometer mounted to the first wheel and configured to generate a first tachometer signal indicating rotation of the first wheel, and a first brake configured to brake the first wheel.

摘要： Embodiments assess vehicle noise. One such embodiment defines a computer-based model of a vehicle and automatically determines aerodynamic performance and propulsion performance of the vehicle based on the defined computer-based model. Responsively, a flight-dynamics simulation of the vehicle is performed using the determined aerodynamic performance and propulsion performance. Performing the flight-dynamics simulation produces flight status data. The flight status data is automatically down-sampled to generate a reduced dataset. A high-fidelity flow simulation of the vehicle is performed using the reduced dataset. Performing the high-fidelity flow simulation determines in-flight aerodynamic and aeroacoustic performance of the vehicle. In turn, based on the determined in-flight aerodynamic and aeroacoustic performance, noise physical characteristics of the vehicle are determined and an indication of the determined noise physical characteristics is stored in computer memory.
