ARJ21-700飞机冰脱落数值模拟
Numerical simulation of ice shedding from ARJ21-700
摘要
Abstract
Rear fuselage mounted engine is applied on ARJ21-700 aerocraft.Under some special conditions,the ice shedding from the surface may do harm to the engine.In order to research the relationship between the ice shape,shedding pose or shedding position and the probability of entering engine,MBNS3D is employed to calculate the flowfield of ARJ21-700 and variable ice shapes,and the trajectories of ice shedding from head and upper wing of craft are calculated by solvering six-degree equations.It is found that this method can calculate large amount of trajectories quickly and precisely.Finally,the rule of ice blocks being pulled into the engine is concluded,to provide surpport to the airworthy certification of ARJ21-700.关键词
