论文摘要
本文使用coanda效应来减少电动机，噪声的来源，并找到具有足够的升力力的低噪声材料，以便它可以实现声学隐形无人机。但是，必须有一些时刻需要安静地操作无人机，那么如何减少噪音？在先前的研究中，也有稳定的尝试使用Coanda效应生产无人机，但从未尝试通过Coanda UAV实现声学隐形。但是Coanda效应仅使用一个电动机，并且在结构上很安静。因此，我们试图找到安静的方法（材料，结构），同时通过Coanda效应具有足够的刺激。验证进行了实验。对照组使用最常见的二极管类型，并通过在相同条件下测试各种结构和材料并测量噪声来确定假设是否正确。使用Coanda效应的无人机不具有任何不变的形状或结构，并且内部空间也为空。这就是为什么我们提出的Coanda效应可以通过后续研究改善的原因。这就是为什么Coanda效应无人机可以为隐形无人机打开新的边界。
This paper uses Coanda Effect to reduce motors, the source of noise, and finds low noise materials with sufficient lift force so that it can achieve acoustical stealth UAVs.According to NASA research [1], the noise of UAVs is better heard to people. But there must be some moments when we need to operate the drones quietly, so how can we reduce the noise? In previous research, there have also been steady attempts to produce UAVs using Coanda Effect, but have never tried to achieve Acoustic Stealth through Coanda UAVs. But Coanda Effect uses only one motor and is structurally quiet. So we tried to find quiet methods (materials, structures) while at the same time having sufficient stimulus through the Coanda Effect. Verification went through experiments. The control group used the most common type of Quadrone, and determine if the hypothesis is correct by testing various structures and materials under the same conditions, and measuring noise. UAVs using Coanda Effect are not of any shape or structure that is not changeable, and internal space is also empty. That's why the Coanda Effect UAV we present can be improved through follow-up research. That's why the Coanda Effect UAV could open up a new frontier for the Stealth UAVs.
