摘要： Simulation apparatus for evaluation of a system's (1) , such as a vehicle's, performance is described. The apparatus comprises imposition means (2), simulation control means (13) and sensor means (3), such that, in use, the system is arranged to be in communication with the imposition means and with the sensor means. The simulation control means is operative to cause the imposition means to act on the system in response to a signal received from the sensor means so as to provide a simulated effect corresponding to said signal. The imposition means may comprise a moveable vehicle support structure. The apparatus may additionally comprise controllable fluid flow means (15) , such that, in use, the vehicle is positioned in the path of the fluid flow. Also described is apparatus for controlling a production process, comprising a plurality of spaced apart sensors.

摘要： A method of detecting shaft break in a gas turbine engine (10) having a shaft system (48). The shaft system (48) comprising a shaft (36) that couples a compressor (16) and a turbine (24). First construct a frequency model (60) of the shaft system (48). Then determine a notch frequency (f N ) and a first torsional frequency (fu) for the shaft system (48) from the model (60). Then in real time measure a rotational speed of the shaft (36); detect the presence or absence of a feature (62, 64) at at least one of the notch frequency (f N ) and the first torsional frequency (f 1T ) in the measured speed; and generate a shaft break signal in response to the absence of at least one of the features (62, 64).

摘要： A shaft break detection system (68a) and a method of detecting shaft break for a gas turbine engine. A first indication is calculated from measured rotational speed of a shaft. A second indication (68b) is calculated from the rotational speed. A shaft break signal is generated if both indications are true.
