设计制造了一套远程压力输送自动投饵系统,简要介绍了其基本原理、工作流程和功能特点。详细阐释了系统配备的分配器设计原则和设计方法。在分析S形弯管内物料运动状态的基础上初步确定了滑管式分配器的基本设计原则:将分配器的类型根据支管布置形式的不同区分为上半圆式和下半圆式;再选择合适的"弯曲半径-管径-支管数"组合使S形弯管的物料流动性能最优,且使分配板上的支管孔边缘距离符合电子定位器件和密封器件的安装要求;使弯管管径小于前端直管管径;使分配器的全尺寸尽可能地小。根据基本设计原则进行了计算公式推导和设计演示,获得了弯曲半径、孔边距和全尺寸的计算公式及其与管径、支管数组合的优化选择方法,进而确定了分配器的基本设计流程和方法,为同类型分配器的设计提供参考。

行政行为的可接受性是行政行为相对人、利害关系人对行政行为的合法性、合理性的认同和接受程度,其核心是行政主体在行政行为过程中应当征求和充分考虑相对人、利害关系人的意见,并尽量达成一致意见,得到其同意。行政行为的可接受性是行政行为的应然价值追求,是建设人民满意的服务型政府的现实要求。从行政法的角度看,当前影响行政行为可接受性提高的主要因素有二,一是行政行为由行政主体单方意志决定的传统行政法制观念根深蒂固,二是有关立法没有明确要求行政主体必须充分尊重和考虑利害关系人、相对人的意见。提高行政行为可接受性要求行政机关及其工作人员转变行政行为由行政主体单方意志决定的传统行政法制观念,代之以行政行为尽量由行政主体与行政相对人、利害关系人双方意志决定的民主平等行政法治观念,在此基础上,通过完善立法,建立行政主体对抽象行政行为制定过程中未予采纳的不同意见的反馈制度,建立行政主体对具体行政行为中未予采纳的行政相对人、利害关系人意见的进一步说明理由制度。

主要分析了舰载直升机在母舰甲板上方悬停时的平衡特性。采用CFD方法计算了母舰甲板上方的气流场,建立了适用于舰载环境的直升机飞行动力学模型,计算了UH-60A直升机在流场悬停位置处的配平值。在此基础上,计算了旋翼入流、载荷、功率以及机体姿态状态量的响应。仿真结果表明,舰面流场的非线性、不均匀等特点对计算值影响较大。通过与无离散模型计算结果的对比,表明了流场对直升机旋翼的垂向载荷影响较大,对机体姿态角速率的影响更为显著,破坏了直升机的平衡,对直升机在舰面流场环境下的飞行控制系统提出了更高的要求。
