摘要：翼型的设计除了追求高升阻比设计指标外,同时零升力矩和力矩拐折特性也是非常重要的设计指标,否则将导致飞机较大的配平阻力和较差的力矩特性。本文在不改变翼型基本特性的前提下,给出了改善翼型零升力矩和力矩拐折特性的一种方法,通过计算和风洞试验验证了该方法的可行性,并进行了流动机理的分析。

摘要：为改进攻击型无人机待机段的飞行搜索性能,应用以最大值原理为基础的最优搜索理论对无人机待机搜索路线进行研究,得出光栅式、螺旋式和扫雪式3种搜索路线,并通过计算机仿真与传统的8字式搜索方式进行了比较。仿真结果表明,优化设计结果是合理的,证实了其有效性和可行性。

摘要：A cooperative control method of multi-class UAV(unmanned air vehicle) team is *** the mission,the UAVs perform search,classification,attack and battle damage assessment(BDA) tasks at various locations,which involves a combination of the team intelligence type of decision making combined with control,estimate and real-time trajectory *** search-theoretic approach based on rate of return(ROR) maps is developed to get the cooperative search *** are developed and views are combined to maximize the probability of correct target identification over various aspect *** Carle simulation runs for the scenario to evaluate the performance of the approach with various decision parameters,UAVs distributions and UAV team *** results show that the cooperative behavior can significantly improve the operational effectiveness of UAV team,and the cooperative control allows for near optimal solution of the correlative behavior of a group of UAVs in battlefield.
