Abstract

Purpose

This paper aims to describe a numerical simulation method of ice accretion on BO105 helicopter blades for predicting the effects of trailing edge flap deflection on ice accretion.

Design/methodology/approach

A numerical simulation method of ice accretion is established based on Myers model. Next, the shape and location of ice accretion of NACA0012 airfoil are calculated, and a comparison between calculated results and experimental data is made to validate the method. This method is used to investigate the effect of trailing edge flap deflection on ice accretion of a rotor blade.

Findings

The numerical method is feasible and effective to study the ice accretion on helicopter rotor blades. The downward deflection of the trailing edge flap affects the shape of the ice.

Practical implications

This method can be further used to predict the ice accretion in actual flights of the helicopters with multielement airfoils.

Originality/value

The numerical simulation method here can lay a foundation of the research about helicopter flight performance in icing condition through predicting the shape and location of ice accretion on rotor blades.

带有后缘襟翼的直升机旋翼上积冰的数值模拟

设计/方法/途径建立了基于迈尔斯模型的积冰数值模拟方法。然后，计算了 NACA0012 翼面积冰的形状和位置，并将计算结果与实验数据进行对比，以验证该方法的有效性。该方法用于研究后缘襟翼挠度对旋翼桨叶积冰的影响。后缘襟翼向下偏转会影响冰的形状。实用意义该方法可进一步用于预测多元素翼面直升机实际飞行中的积冰情况。
