Designing a Multi-Functional Vehicle for Aerial Hydraulic Maintenance

Abstract

Abstract-Hydraulic maintenance vehicle for aviation is a critical ground device to ensure the flight safety and the provision of hydraulic oil. A novel multi-functional vehicle for aerial hydraulic maintenance is designed for proposing a maintenance approach for modern aircraft. Aiming at issues of existing ground maintenance devices, this work attempts to meet three design requirements as follows: (i) All purpose in one vehicle. This design offers a solution integrating fueling, pressure supplying and cleaning in one vehicle, so as to overcome single function issue of the existing devices. (ii) Active hydraulic oil purification. A high-speed centrifugal separation method has been employed to dealing with low efficiency and easy pollution of existing passive oil purification. (iii) Good motility. Aiming at two issues of large occupation and frequent operation transformation, the hydraulic system, power system, control system and auxiliary mechanism are installed on a drag-and-drop vehicle body to share a compact structure, flexible mobility, and convenient operation.
