不良人石油动力多旋翼无人机或电动无人机将被更换,看空气“拖拉机”什么?

吉克隽逸

    很抱歉,我今天要办一次产权晚会,但我保证以下内容是干货。标题中的飞行拖拉机实际上是一种电动多转子植保无人机。之所以叫飞行拖拉机,是因为这种拖拉机功率大、声音大,就像空中飞行的拖拉机。开始谈正事。近年来,植物保护无人机普遍不热,只有上市公司有十多家在宣传无人机的概念。2017,十几家无人机公司募集了超过10亿元。2018,无人机的销售非常受欢迎。一些专家预测,超过20000架无人机将售出,比2017年同期增长一倍。然而,无论多流行,无可争辩的事实是,目前主要的多旋翼植保无人机有效载荷太小,运行时间短,速度低,很难为机组人员赚钱。这不是耸人听闻的。目前,新疆市场上销售的MG-1P和极限飞行P20有效载荷为10kg。一次手术持续10-25分钟。实际操作时间不超过10分钟。一次起飞的有效面积为0.87.1.33 hm2(13-20亩)。可以说他们经常出发,工作很匆忙,飞机也很匆忙。但是我一天不能做很多工作。据业内专家介绍,目前电动多旋翼飞机很难解决这一问题。为了提高负载质量,延长使用寿命,需要安装更多的电池和大功率电动机。但大功率电动机和电池本身需要较多的起步功率,而且成本会成倍增加,因此在理论上是可行的,而实际上是不可行的,而且电动多转子处于“囚徒困境”。目前,解决这两个问题的唯一途径就是改变动力源,如采用燃油驱动方式,将发动机转化为发动机,再将电力转化为油,采用最有效的传统方式解决无人机质量和耐久性的瓶颈。这就是我们今天要重点介绍的油动力多转子植保无人机。1。根据动力源的不同,油驱动多转子植保无人机可分为电动无人机、油驱动无人机和油电混合动力无人机。根据机翼的不同,可分为固定机翼、单转子和多转子三种类型。固定翼和单转子主要由油压发动机驱动,而多转子主要由电力驱动,因此多转子电动飞机的主要问题是负载小,持续时间短,问题在于电池。今天我们将介绍一种新型的多转子植保无人机:油驱动多转子直接驱动植保无人机。在全球范围内,只有中国从事油动力多转子植保无人机,据我所知,目前中国只有两家公司,所以今天您能看到这份手稿也是幸运的,因为很少有人知道这两家公司。油动多转子还应该有四、六、八翼,但在具体的开发中,考虑到八翼需要八台发动机,成本明显较高,而且发动机越多,问题频率越高,控制也越复杂。另一方面,由于发动机是固定在机翼上的,所以必须考虑在一翼上的发动机意外停止时,四翼飞机会因为不平衡而坠毁,所以最好的解决办法是六翼。这在理论上和实际上都是如此,两种国产多转子植保无人机都是选用的六轴模型。具体地,油驱动多转子无人机使用多个发动机来驱动螺旋桨旋转以提供动力,这与油驱动单转子无人机本质上不同。根据其结构不同,可分为两类:燃料直接驱动多转子和燃料变桨距多转子。直观地,油驱动多转子具有多个具有多个机翼的发动机,并且机翼直接布置在发动机上。这是和电力最大的区别,所以如果你看到真正的机器,很容易区分。首先看燃料直接驱动多转子。这种飞机通过改变发动机转速直接控制无人机的飞行姿态,这与电动多旋翼的驱动方式和原理基本相同。燃油驱动的多旋翼无人机有效地解决了无人机的机载质量和耐久性问题。但是,在解决老问题时,又会出现发动机寿命短、抗风性差、响应速度慢、振动大等问题,振动对飞行控制的影响也很大。看看油动力可变螺距多转子。油驱动螺距多转子与油驱动多转子的便利性不同。油驱动螺距通过改变螺旋桨的螺距来改变升力。油驱动多转子的响应速度比油驱动多转子的响应速度快得多。同时,与直接驱动相比,发动机的寿命不会缩短,在最佳转速状态下,发动机的转速是恒定的。目前,国内一些公司已将该技术应用于植保无人机。2。空气拖拉机的优点是油驱动多转子植保无人机是一种“替代品”,那么它有什么特殊之处呢?这些特点对以后的推广有好处吗?(1)负荷大,耐久性强。如上所述,电动单转子植保无人机的有效载荷为10kg,单次运行持续10-25分钟,实际运行时间小于10分钟。可以说,我国农机产品还处于消费水平与专业水平之间的过渡阶段,远未达到成熟的农机产品标准。根据长丰公司的现场试验,油驱动多转子植保无人机的最大载荷可达100kg,最长寿命为4小时。当然,这是实验室里最好的数据。实际可靠的数据应该是30-70kg的载荷和1-3H的持续时间。相比之下,电站保护无人机的有效载荷和耐久性明显不同于油载无人机,油载无人机的优势一般不明显。(2)面积大,效率高。基于多负荷、长飞行时间的特点,油压多转子不会频繁起飞,一次可完成30kg以上的喷涂作业和飞行一小时以上。在现场,10kg电动多转子每天可运行20-33.3hm2(300-500mu),而油驱动多转子每天可运行100hm2(1500mu),200hm2(3000mu)用于单个大块和高级控制。(3)成本低,利润高。使用成本不仅仅取决于燃烧多少油或者使用多少千瓦时的电。这里的使用成本是指机器的折旧加上燃料和电池的成本。根据长丰公司的计算,电动多旋翼飞机的平均运行成本为45-60元/hm2(3-4元/亩),而油动多旋翼飞机的平均运行成本为15-30元/hm2(1-2元/亩),为电成本的1/3-1/2。(4)渗透性强,运行效果好。非专业人士可能不清楚植保无人机的穿透力与飞机的载荷质量成正比,因为载荷质量、机翼长度、旋转速度、旋转形成的风场大,穿透力强。显然,负载为60kg的油动力多转子的穿透力不同于负载为10kg的电动多转子的穿透力。这种强渗透对玉米、甘蔗、果园等高秆密植作物的植物保护非常有效。三。在世界上有限数量的空气拖拉机的产品开发中,先进的企业家会形成严重的路径依赖,而先进的企业家往往盲目地向先进的企业家学习,这可能导致一个行业的产品同质化和简化。国内植保型无人机也出现了这种不良趋势,目前大部分企业都追随新疆10kg电动多转子生产线。尽管与电动多转子相比,油动多转子具有明显的优势和特点,但是国内没有多少企业愿意遵循这一路线,因此笔者只发现了三个。其中,燃油直驱公司为深圳长丰和辽宁庄龙科技有限公司,而油驱动变桨多转子只能找到新的三板上市公司岩瓦。虽然只有三家公司涉足油动多转子,但他们的产品极具代表性,具有自己的特点。4。深圳市长丰及其天马-1“空气拖拉机”深圳长丰信息技术有限公司成立于2014年,应与新疆、鸡飞等公司同时启动。公司是典型的学生创业型企业。据业内专家介绍,深圳长丰是全球油驱动多转子植保无人机的先驱,为行业乃至世界做出了贡献。长丰公司的主要产品是天马一号。该无人机有六个转子和六个内燃机。使用92的汽油作为燃料,40的药物负荷。其运行效率为8~16hm2/h(120~240MU/h)。碳纤维与航空铝合金组合的机构结构确保了强度和刚度,同时降低了机身质量,使连续性最大化。航行时间为129分钟,一天可工作133.3 hm2(2000亩)。特别值得注意的是,国内用于植保无人机的发动机寿命为200-300小时,用户使用成本很高。长丰公司与国外发动机制造商合作,对发动机进行优化设计,使发动机寿命达到1000小时,大大提高了产品的性价比。此外,长丰公司没有直接利用现有的飞行控制系统,而是根据油压植保无人机的特点,开发了具有自主知识产权的直驱式燃油飞行控制系统。5。辽宁壮龙DZ310无人机成立于2015。公司拥有一大批人才,其中有一名全国千人规划专家和一百多名员工,其中一半是技术开发人员。公司最大的优势在于位于东北的大型种植区,所以其“雄厚”的实际经营面积大,是具有实践经验的模型,不是概念机。“大庄”也是一架6旋翼飞机,载有6台发动机和92_汽油作为燃料,载有60升药品和30L油箱容量。在飞行控制方面,它具有多旋翼无人机的单键起降、自主飞行、航路记忆功能、智能流量控制、重载高压、强风穿透等功能。操作效率为16-32 hm2/h(240~480MU/h)/分钟,工作喷雾范围为8~18m,超出电动多旋翼3~6m范围,每天可工作133.3 hm2以上(2000亩)。“强”的优点在于它的实用性。所售产品积累了超过30000小时的操作经验,操作面积超过333000hm2(500万亩)。它是一个真正的应用级机器。它在中国东北很有名,而且供不应求。据说定单已定于2019年6月。6。油压变桨多转子WZ110是笔者一直关注的新三板上市公司。WZ110型油压变桨距多旋翼无人机的设计思想结合了电动多旋翼和油压直升机的优点,提高了飞机的综合性能。超负荷120分钟,超负荷20公斤。WZ110在2016引入,引起了业界的极大轰动。据说,它可以用于农业植物保护和飞行防御领域。但两年多后,该模型还没有进入应用级别,也无法在其网站上找到。也许是因为价格,该产品是使用岩瓦在电阵列巡航或其他领域,或暂时隐藏。
