Abstract
In order to facilitate the rapid drainage of airport apron in the special weather (such as heavy rain and snow), the apron is usually designed to have a certain slope. However, this slope leads to a difficult problem that chocks are not easy to take out when the airplane leave airport. In order to solve this problem, a hydraulic chocks design scheme is firstly proposed. The aircraft hydraulic chock involves two systems, which are named the slider system and the rod system Taking Boeing 737-800 as an example, this paper firstly makes reasonable assumptions. And then uses a hydraulic chocks to analyze the aircraft’s stress situation. Through the calculation and analysis of the scheme, the feasibility of the scheme is verified, it also completely solve problem that chocks are not easy to take out. At the same time, the use of the hydraulic wheel block also avoids injury to personnel and waste of time.
