直升飞机的用途是什么?
直升飞机的用途有运输、巡逻、旅游、救护等多个领域。
直升机的突出特点是可以做低空(离地面数米)、低速(从悬停开始)和机头方向不变的机动飞行,特别是可在小面积场地垂直起降。由于这些特点使其具有广阔的用途及发展前景。
在军用方面已广泛应用于对地攻击、机降登陆、武器运送、后勤支援、战场救护、侦察巡逻、指挥控制、通信联络、反潜扫雷、电子对抗等。在民用方面应用于短途运输、医疗救护、救灾救生、紧急营救、吊装设备、地质勘探、护林灭火、空中摄影等。
直升飞机的速度:
直升机的更大时速可达300km/h以上,俯冲极限速度近400km/h,实用升限可达6000米(世界纪录为12450m),一般航程可达600~800km左右。携带机内、外副油箱转场航程可达2000km以上。根据不同的需要直升机有不同的起飞重量。
当前世界上投入使用的重型直升机更大的是俄罗斯的米-26(更大起飞重量达56t,有效载荷20t)。当前实际应用的是机械驱动式的单旋翼直升机及双旋翼直升机,其中又以单旋翼直升机数量最多。

直升是什么意思?
有些学校是有初中部和高中部的,直升就是可以从初三升高一,无论升中考分数怎样,相当于大学的保研吧
什么是直升机?
直升机是能垂直起降和悬停在空中的飞机。它转向灵活,能原地转弯,反应迅速,并能前飞、后飞和侧飞。直升机通常携带机枪和火箭发射器,既可用于海上巡逻、运送兵员和吊运装备等,又可超低空攻击地面和水上目标及反潜艇、反坦克等,尤其适合在热带丛林、山区等地形复杂和交通不便的地带飞行作战。不管是在峡谷、森林、河滩,还是在高大的建筑物顶部,它都能随意降落和起飞。
直升机飞行高度低,速度慢,很容易遭到敌方防空武器甚至轻武器的攻击。
直升机的头顶上有台很大的“风扇”,那是它的升力部件——旋转机翼,有的机身底下装有两栖起落架和短翼浮筒,还能够在水面上起降或漂浮。配上挂钩,它能吊住轻型坦克在空中飞行。
直升高中是什么意思
直升高中的意思是:不需要参加中考,直接升入高中。直升生一般指学校为了留下优秀的生源,与学习成绩优异,并且有意向的初中生签约可以直升入该校高中。
初中学业水平考试,简称“中考”,是检验初中在校生是否达到初中学业水平的考试;它是初中毕业证书发放的必要条件,考试科目将国家课程方案所规定的学科全部列入初中学业水平考试的范围。
