摘要： The invention relates to a drive system for an, in particular electrically driven, aircraft. The drive system is provided with thrust measuring means which measure a currently effective thrust of the thrust generator of the aircraft. The measurement values obtained in this way are supplied to a controller of the drive system, which uses the measured thrust, along with other parameters, to control the drive system such that a selectable parameter, e.g. the thrust or an efficiency of the drive system, can be is optimised.

摘要： One example is test system for testing the propulsion system(s) of vehicles. The test system includes a retention fixture, a linking device, a test logic, a measurement device and a result logic. The retention fixture is for rigidly mounting first and second vehicles to the retention fixture. The linking device links propulsion systems of the first and second vehicles so that the propulsion systems operate a different rates. The test logic subjects the second vehicle's propulsion system to a propulsion test. The measurement device measures at least one parameter associated with the propulsion system of the first vehicle while the first vehicle is subjected to the propulsion test. The result logic determines if the first vehicle under test passed the propulsion test based, in part, on the at least one parameter and generates an indication if the first vehicle passed or failed the propulsion test.

摘要： A ball mount for measuring tongue weight of a trailer is disclosed. The ball mount can include a ball portion having a hitch ball configured to couple with a tongue of a trailer. The ball mount can also include a hitch portion for interfacing with a hitch receiver associated with a vehicle. In addition, the ball mount can include a load measurement device associated with the ball portion to determine a magnitude of a downward force on the hitch ball. The load measurement device can include a reservoir having a fluid and a piston disposed therein, and a pressure sensor in fluid communication with the reservoir. The hitch ball can be configured to exert a force on the piston, thereby affecting a pressure of the fluid in response to the downward force on the hitch ball.

摘要： A measuring device (60) is configured for measuring forces or torques between a motorized vehicle (1) and a trailer or attachment which is towed or pushed thereby. The measuring device (60) has at least three sensor elements (79, 80) arranged on a carrier (71), transversely with respect to a virtual longitudinal axis of the motorized vehicle (1) and spaced apart from one another. The measuring device (60) is arranged in a coupling region between the motorized vehicle (1) and the pulled or pushed trailer or attachment. In order to transmit their measured values, the sensor elements (79, 80) are connected to an evaluation device (40), which is configured to convert these measured values into signals for force displays and/or torque displays according to magnitude and direction.

摘要： Embodiments of the invention relate to a thrust stand and a method of measuring thrust. Embodiments of the invention pertain to a method of calibrating a thrust stand. Embodiments of the subject thrust stand can incorporate a passive eddy current based damper. Specific embodiments of the passive eddy current based damper can function without contact with the balance arm. Further specific embodiments of the passive eddy current based damper can be used in a vacuum. Embodiments can utilize signal analysis techniques to identify and reduce noise. A logarithmic decrement method can be used to calibrate the thrust stand. Force measurements can be made with embodiments of the subject thrust stand for a standard macroscale dielectric barrier discharge (DBD) plasma actuator and/or other thrust producing devices.

摘要： A method and system includes predicting energy consumption of a vehicle using a statistical model. The method includes obtaining a plurality of input vectors for plurality of points in time, wherein each input vector includes a plurality of variables with a weight vector. Thereafter, the energy level for each input vector is captured for each point in time. Subsequent to capturing the energy level, the method includes predicting a change in energy level of the vehicle using the statistical model.

摘要： One aspect is a structural fault estimation system for a rotor system. The structural fault estimation system includes a plurality of sensors operable to provide a plurality of measured rotor loads and motion of the rotor system. A rotor loads and motion estimator is operable to produce a plurality of estimated rotor loads and motion for the rotor system. A rotor fault estimator is operable to determine residual rotor loads and motion as a difference between the measured rotor loads and motion and the estimated rotor loads and motion, and estimate fault magnitudes for the rotor system using least squares relative to fault models and the residual rotor loads and motion. The structural fault estimation system can perform structural fault estimation in real-time on an aircraft while in operation.
