Aircraft Takeoff Taxiing Model Based on Lagrange Interpolation Algorithm

Research on aircraft takeoff taxiing model has a great significance upon evaluation of aircraft performance, design of airport runway and warfare simulation. Because the aircraft takeoff taxiing is a complex nonlinear process, existing numerical calculation models are ordinarily based on the energy method or assumption of moment equilibrium, which leads to complex modeling process and low precision. In this paper, we establish a takeoff taxiing model by numerical integration method which is easy to implement, and obtain the parameters of running distance calculation formula based on Lagrange interpolation algorithm [1]. At the end of this paper, we use the characteristic parameters of a specific aircraft as model inputs to validate the correctness and accuracy of this model by comparing the model output and actual flight data.
