高空螺旋桨如何允许高精度地映射大面积
This article was originally published inGeomatics World。
Wingtra正在推出高空螺旋桨,使专业的映射无人机能够以前所未有的准确度和覆盖率捕获超过2,500米(8200英尺)的数据超过2,500米(8200英尺)。南美洲,中国,中欧等地区的客户现在可以将高地形映射到1CM地面样品距离(GSD)。
Specifically, the new high-altitude propellers and supporting software allow take-off at altitudes of up to 4,800m (15,700ft) AMSL and flight at altitudes of up to 5,000m (16,400ft) AMSL.
“这是一款游戏更改器,为客户飞行并收集到目前为止挑战到达的地形上的数据,”Wingtra的联合创始人和首席执行官Maximilian Boosfeld说。
WhileWingtraOne被定价为包装捆绑 - 使用有效载荷,软件,基站和所需的一切,您需要开箱即用 - 这些螺旋桨根据特定需求单独出售。
How does altitude affect flight, and how does VTOL overcome that?
As air becomes thinner at higher altitudes, the ability of standard propellers to generate enough thrust to lift an aircraft is compromised. Their shape must change to lift through these conditions. As it is a VTOL drone, WingtraOne relies on this upward lift only for the take-off and landing portion of its flight. The rest of its flight time, in cruise mode, is where its advantages become obvious.
高海拔往往与更强硬,令人讨厌的条件和表现极致挑战有关。但在这种情况下,WingTraone的固定翼设计使其能够更快地飞行,同时仅略微减少范围。这是因为vol.允许它携带较重和更高质量的摄像头,包括RX1R II有效载荷。
“在这里,我可以驾驶飞行,在3cm gsd占地200ha需要25分钟,”Boosfeld说。“超过4000米(13,000英尺),你仍然可以在更少的时间内覆盖同一个200哈 - 20分钟。因此,如果您没有超过200ha的项目,则安全,您实际上是飞行和获取高达20%的数据。“

Multirotors and fixed-wings at high altitudes
要了解新的高空螺旋桨中的独特产品,它有助于查看多路电流和固定翼无人机以及它们在这些条件下的表现方式。
具体地,有限的空间多电阻器可以通过高海拔的薄空气进一步损害。某些类型的多路电池可以提供特殊的螺旋桨来处理此操作。但无论如何,他们将在较薄的空气中使用更多的能量来留在飞行中。在这种情况下,客户不仅会遇到非常短的飞行时间和有限的覆盖范围,而且还有很多设置和处理开销,以运行多个航班,甚至一个相对较小的区域,如100ha。
As for fixed-wing drones, the terrain at altitudes above 3000 m (9840 ft) lacks grass and has few, if any, large, soft areas where they can belly land. Even if there is somewhere for them to land, fixed-wings face limits on the quality of the payloads they can carry, so images may be compromised when the cruise flight speed picks up.

Guidance and safety
新的螺旋桨现在可以待售,作为任何WingraonOne的配件,并且易于通过环形系统区分。本月首次发货日期发布的软件更新提供了指导和安全功能。也就是说,除非附着高空螺旋桨,否则计划超过2500米(8200英尺)的航班。然后,在低于2500米(8200英尺)以下时,可以更换正常的WingTraone螺旋桨,因为它们提高较低海拔效率。将通过新的复杂算法监控飞行时间和电池电量的充电状态,该算法也可以考虑到高度。
