20世纪90年代是直升机发展的第四阶段，出现了目视、声学、红外及雷达综合隐身设计的武装侦察直升机。典型机种有：美国的RAH-66和S-92，国际合作的“虎”、NH90和EH101等，称为第四代直升机。 这个阶段的直升机具有以下特点：采用第3代涡轴发动机，这种发动机虽然仍采用自由涡轴结构，但采用了先进的发动机全权数字控制系统及自动监控系统，并与机载计算机管理系统集成在一起，有了显著的技术进步和综合特性。第3代涡轴发动机的耗油率仅为28千克/千瓦小时，低于活塞式发动机的耗油率。其代表性的发动机有T800、RTM322和RTM390。桨叶采用碳纤维、凯芙拉等高级复合材料制成，桨叶寿命达到无限。新型桨尖形状繁多，较突出的有抛物线后掠形和先前掠再后掠的BERP桨尖。这些新桨尖的共同特点是可以减弱桨尖的压缩性效应，改善桨叶的气动载荷分布，降低旋翼的振动和噪声，提高旋翼的气动效率。球柔性和无轴承桨毂获得了广泛应用，桨毂壳体及桨叶的连接件采用复合材料，使结构更为紧凑，重量大为降低，阻力大大减小。旋翼升阻比达到5，旋翼效率为8。这个阶段应用了无尾桨反扭矩系统，其优点是具有良好的操纵响应特性、振动小、噪声低，不需要尾传动轴和尾减速，使零部件数量大大减小，因而提高了可维护性。复合材料在直升机上获得了前所未有的广泛应用。直升机开始采用复合材料主结构，复合材料的应用比例大幅度上升，通常占机体结构重量的30~50%。这一时期的民用型直升机的空重/总重比约为37。高度集成化的电子设备。计算机技术、信息技术及智能技术在直升机上获得应用，直升机电子设备朝着高度集成化方向发展。这一时期的直升机，采用了先进的增稳增控装置，用电传、光传操纵取代了常规的操纵系统，采用先进的捷联惯导、卫星导航设备及组合导航技术，先进的通讯、识别及信息传输设备，先进的目标识别、瞄准、武器发射等火控设备及先进的电子对抗设备，采用了总线信息传输与数据融合技术，并正向传感器融合方向发展。机上的电子、火控及飞行控制系统等通过多余度数字数据总线交连，实现了信息共享。采用了多功能集成显示技术，用少量多功能显示器代替大量的单个仪表，通过键盘控制显示直升机的飞行信息，利用中央计算机对通讯、导航、飞行控制、敌我识别、电子对抗、系统监视、武器火控的信息进行集成处理从而进行集成控制。采用这类先进的集成电子设备，大大简化了直升机座舱布局和仪表板布置，系统部件得到简化，重量大大减轻。更主要的是极大地减轻了飞行员工作负担，改善了直升机的飞机品质和使用性能。直升机的全机升阻比达到6，振动水平降到05g，噪声水平小于90分贝，最大速度可达到350千米/小时。

毕业论文怎么写？首先要弄明白作格式，其次是选题，再次是确定立意，最后是材料搜集和写作。 一、毕业论文格式： 1、标题。首行居中，字号一般比正文大两号。 2、作者。标题下一行，居中，字号比标题小一号。 3、摘要。一般100-200字内。字号同

共轴式双旋翼构造类似于钟表，下旋翼固定在管状旋翼轴上，上旋翼的旋翼轴插在其中，发动机通过两套减速机构驱动旋翼，两副旋翼旋转方向相反可以抵消扭矩，取消尾梁，增大机体空间，但也是有代价的，共旋翼直升机不适合作大机动动作，因为两副旋翼旋转方向相反，所以进动力方向也相反，而旋翼刚度又较差，大机动飞行时两副旋翼在进动力作用下有相碰的危险，所以像卡50这类共旋翼武装直升机两副旋翼分得很开，但同时又增加了高度的铰链机构的复杂性。目前只有俄罗斯的卡莫夫飞机设计局发展了实用型的共旋翼直升机。值得一提的是美国MD500/530直升机只有一个主旋翼，但它也取消了尾桨，这是全世界唯一一款无尾桨的单旋翼直升机，它是用另一种方式平衡旋翼力矩，动力来源于涡轴发动机的排气涵道。这里有篇论文题目，直接网上能搜到，希望对你有用。《卡_28直升机及其共轴式双旋翼系统的特性》 - 直升机技术

不是这样的，两个桨虽然方向不同，但都是有动力的；旋翼的旋转会使机身受到产生一个反向的扭力，所以为了平衡这个力，普通直升机都会有一个产生横向推力的尾翼，以免机身旋转，双轴反旋翼直升机则是靠两个旋翼不同方向的旋转自己抵消掉，所以就不用尾翼了。

For my own perspective， taking areoplanes has its proside and also Aeroplanes are convinient for its speed， and air services are Many people would like to try this kind of But Aeroplane industries are not well developed nowadays in C Tickets are money-consuming， airspace is congested and a little bit dangerous for some The expandation of the Industry was limited by Chinese Airforce- there're simply few airports for General Aviation! The best mean of transportation in China is railway Railways means less pollution， comfortable beds and The railway department is trying to create quick railways， which was called 'CRH'- the Chinese Railway H I think this kind of techonology will bring us greater enjoyment ，more exitement and more anticipation to the
