Representing vehicles in a customizable virtual environment is disclosed. One embodiment includes a controlled environment including prototype vehicles and a virtual environment including virtual representations of the prototype vehicles. The virtual environment is a display that includes an environment scenario, a number of virtual objects, and the various represented vehicles. The represented vehicles are linked to the prototype vehicles by communicating kinematic data from the prototype vehicles to the virtual vehicles real-time. The positions of the represented vehicles are updated based on the communicated kinematic data such that the virtual environment is a realistic visualization of the prototype vehicles. In addition, the virtual environment is highly customizable. In an embodiment, customizing the virtual environment includes generating reference views for the represented vehicles, editing the environment scenario, editing the virtual objects, editing the represented vehicles, and generating a mission scenario of the reference views.

A system and methods for life optimal power management of a distributed or centralized battery network system for use in aircraft functions and subsystems are disclosed. The method determines power priority of the subsystems, and selectively distributes power from the battery network system to the subsystems based on the power priority. Concurrently with distributing power, the method manages the energy in the battery network system. To determine whether the battery power is sufficient for aircraft functions, the method also computes and indicates the actual available energy left in the battery network systems. With this approach, the system and methods can provide a persistent power supply in the event an unexpected battery failure occurs, thereby enabling the aircraft to safely maintain flight operability despite a battery failure.

Systems and methods for health data management are disclosed. In one embodiment, a method of monitoring health information for a multi-platform system includes receiving health information from one or more subsystems of a plurality of platforms, and analyzing the health information using one or more reasoner algorithms configured to predict a potential failure of the one or more subsystems. Upon prediction of a potential failure, the method includes providing a prognostic characteristic of the one or more subsystems. In alternate embodiments, the method may further include translating at least some of the health information for each of the one or more subsystems into a common format, and storing the translated health information into a database for subsequent analysis.

Methods and systems for analyzing engine unbalance conditions are disclosed. In one embodiment, a method includes receiving vibrational data from a plurality of locations distributed over an engine and a surrounding engine support structure, and inputting the vibrational data into a neural network inverse model. The neural network inverse model establishes a relationship between the vibrational data and an unbalance condition of the engine, and outputs diagnostic information indicating the unbalance condition of the engine. In a further embodiment, a method further includes subjecting the vibrational data to a Fast Fourier Transformation to extract a desired once per revolution vibrational data prior to input to the neural network inverse model.

A damage-detection apparatus for an aircraft may include a composite structure comprising embedded conductive traces. The embedded conductive traces may be for transmitting a damage-detection signal to indicate if the composite structure has been damaged.
摘要:
A method of testing a component of a mobile platform without using an aircraft control system of the mobile platform, where the component forms a part of the aircraft control system. The method may involve using a test controller independent of the aircraft control system to initiate a test operation. The test operation is used to generate a test signal. The test signal is applied to a test subsystem carried on the mobile platform but operable independent of the aircraft control system. The test subsystem is used to act on the component of the aircraft control system. A response of the component may then be evaluated.
