标准范围

本文件规定了记录最大起飞质量（MTOM）小于150的旋翼动力无人驾驶飞机系统（UAS）周围几个位置瞬时声压时间历程的方法？公斤符合ISO 21895[9]。UAS可以是电力驱动的或燃料驱动的。它不适用于倾转旋翼或倾转翼无人机。它不考虑UAS噪声认证或法规该文件也可用于测量来自具有多个旋翼或单个旋翼的UAS的声压。本文件规定:A）？对不同类别多旋翼动力UAS噪声测量的三种不同测试设施的建议和要求:—？消声室中UAS噪声测试的要求和建议（条款？7）；—？消声风洞中UAS噪声测试的要求和建议（条款？8）；—？室外环境中UAS噪声测试的要求和建议（条款？9）；b）？多旋翼动力无人机在悬停、垂直起降和水平巡航中噪声测量配置的要求和建议；c）？尽量减少气象效应影响的试验配置和程序建议。

This document specifies methods for recording the time history of instantaneous sound pressure in several positions around rotor powered unmanned aircraft systems (UAS) with a maximum take-off mass (MTOM) of less than 150 kg in accordance with ISO 21895^[9]. The UAS can be either electrically powered or fuel-powered. It is not applicable to the tilt-rotor or tilt-wing UAS. It does not account for the UAS noise certification or regulation

This document can also be applied to measure the sound pressure from a UAS with either multiple rotors or a single rotor.

This document specifies:

a)       recommendations and requirements for three different test facilities for the noise measurements of various categories of multirotor-powered UAS:

—     requirements and recommendations of UAS noise tests in anechoic chambers (Clause 7);

—     requirements and recommendations of UAS noise tests in anechoic wind tunnels (Clause 8);

—     requirements and recommendations of UAS noise tests in outdoor environments (Clause 9);

b)       requirements and recommendations for the configuration of noise measurement for multirotor-powered UAS in hover, vertical take-off and landing, and horizontal cruise;

c)        recommendations for the test configuration and procedures to minimize the influence of meteorological effects.
