Purpose

Unmanned aerial vehicles (UAVs) are more affected by adverse wind conditions in especially landing. Therefore, they need to change the runway in use. In case of this change, to eliminate the uncertain maneuvers, there is a need for a special prescribed track. The purpose of this study is the construction of a prescribed track at a single runway to provide a facility to change the runway in use.

Design/methodology/approach

Two forms of prescribed tracks, as standard and alternate, were constructed for UAVs by taking into consideration the key parameters to design flight procedures. Both tracks were assessed in a real-time simulation method. Moreover, unmanned vehicle simulation was used for a validation process.

Findings

According to the real-time simulation results, 8.14 NM and 6.64 NM of flight distance and 5.43 min and 4.43 min of flight time for the standard and alternate prescribed tracks were found, respectively. The obtained results were in favor of the alternate prescribed track. Furthermore, the prescribed track was assessed and validated in both air traffic control and UAV simulations. The feedback of pilots and controllers was very positive for a prescribed track, as it provided them with foresight and time to take care in any situations.

Practical implications

The prescribed track in this paper may be applied by airspace designers and UAV users to perform safe and efficient landing in adverse wind conditions.

Originality/value

In this study, a prescribed track was constructed for UAVs. Quantitative results were achieved using a real-time simulation method in terms of flight distance and flight time. Additionally, validation of the prescribed track was achieved by unmanned air vehicle simulation.

加强无人驾驶飞机的规定航迹

目的

无人机(UAV)尤其在着陆时受不利的风况的影响更大。因此,他们需要更改使用中的跑道。在这种变化的情况下,为了消除不确定的动作,需要特殊的规定轨道。这项研究的目的是在一条跑道上建造一条规定的跑道,以提供一种改变使用中的跑道的设施。

设计/方法/方法

考虑到设计飞行程序的关键参数,为无人机构建了两种形式的规定航迹,即标准航迹和备用航迹。两种轨迹均采用实时仿真方法进行评估。此外,无人驾驶车辆模拟用于验证过程。

发现

根据实时仿真结果,分别发现标准航迹和备用规定航迹的飞行距离为8.14海里和6.64海里,飞行时间分别为5.43分钟和4.43分钟。获得的结果有利于替代规定轨道。此外,在空中交通管制和无人机模拟中都对规定的航迹进行了评估和验证。对于规定的航迹,飞行员和管制员的反馈是非常积极的,因为它为他们提供了在任何情况下都要谨慎的预见力和时间。

实际影响

空域设计人员和无人机用户可以使用本文中规定的航迹在不利的风力条件下执行安全有效的着陆。

创意/价值

在这项研究中,为无人机构建了一条规定的轨道。使用实时模拟方法在飞行距离和飞行时间方面获得了定量结果。另外,通过无人飞行器仿真来实现对预定轨迹的验证。
