The fuel consumption performance of aircraft affects the deployment capacity and profitability of airlines. This paper focus on building a reasonable exponential attenuation model of aircraft fuel consumption performance model based on the actual flight data. In consideration of the feature that the flying distance varies with fuel consumption performance, a RELAX-based algorithm is introduced with...
Combined with fault injection method, Bi-enabling Petri Net model is proposed for fault simulation of Aircraft AC Power System. In the new model, add fault input and state-transition set to the traditional Petri net system, redefine the transition rules, and give its relation matrix description. Then, based on the relation matrix, a dynamic algorithm is proposed to establish the Bi-enabling Petri...
A structure of nonlinear adaptive inverse controller based on Radial Basis Function (RBF) network is proposed to control a hypersonic vehicle with highly nonlinear and strong coupled states. Different from conventional adaptive inverse controllers, the proposed one is constructed by one main controller called Trimmed Adaptive Inverse Controller and two compensators called Attitude Angle Compensator...
For the aviation industry, reliability is bound up with personal safety and economic efficiency. Aircraft reliability data is an important indicator of measuring its running quality. Based on the research of the fault phenomenon and causes and the distribution of component fault, put forward the concept of "directional fault subject" and" fault subject with smooth distribution"...
A multilayered diffraction tomography algorithm for ground penetrating radar is derived in this paper. The algorithm considers the planar air-soil interface and uses the thought of the equivalent speed to solve the problem of multilayered medium. The first Born approximation and the dyadic Green's function are adopted to construct a linear forward model that inverted by fast Fourier transform to meet...
Second generation bandelets transform is a new method for image asymptotically optimal approximation based on capturing the geometric content of image. Relative to the first generation bandelets, the second generation is an construction of absolute discretization which can complete the image dissection through multi-scale analysis and geometric direction analysis. Bayes is an ideal estimation method...
