APU Drive Scheme Design and Feasibility Analysis

In the wake of the environmental protection requirements, the problem of high energy consumption, low efficiency, large pollution and high noise in the aircraft ground taxiing phase has become increasingly prominent. In order to solve these problems, an electric taxiing system emerges as the times require. In this paper, the dynamics model of aircraft taxiing is established to analyse the moving force and power demand used by the commercial aircraft. Under the constraints of existing commercial aircraft structure, the structural arrangement of electric taxiing system is studied and designed. Finally, the aircraft taxiing system was modelled and simulated using the multi-domain simulation platform Simcenter Amesim. The results show that the electric taxiing system can meet the requirements of the ground taxiing capacity of civil aircraft under the constraint of APU power supply.
