面向气流场的直升机舰船上层建筑设计评估方法

开展舰船上层建筑气流场设计评估，目前尚无系统方法。提出一种直升机舰船上层建筑气流场设计定量评估方法。计算舰载直升机受非定常气流施加的力和力矩的时间历程，以力和力矩的积分平方根量化飞行员的操控负荷，以力和力矩的时间平均值量化舰载直升机的操控裕度，并将起降平台空域的温度变化或变化率作为设计评估指标。采用实例验证该方法的工程可应用性。

Evaluation Method of Helicopter Ship Superstructure Design Towards Airflow Field

At present, there is no systematic method to make an evaluation for airflow field design of ship superstructure. A quantitative evaluation method for airflow field design of helicopter ship superstructure is proposed. It is to calculate the time course of force and moment applied by unsteady airflow on ship-borne helicopter, to quantify the pilot control load with the integral square root of force and moment, to quantify the ship-borne helicopter control margin with the time average of force and moment, and to take the temperature change or change rate of take-off and landing platform airspace as a design evaluation index. The applicability of the method in engineering is verified with the instances.
