安装在旋翼机上的涡轮发动机有一个由飞机制造商设计和生产的排气系统。排气系统的主要功能是引导热排气离开机身。排气系统可能包括连接到发动机的排气尾管和作为旋翼机一部分的排气整流罩。发动机制造商规定了基准“裁判”排气管设计，保证的发动机性能基于裁判排气管和排气管出口直径的使用。 旋翼机上使用的配置可能不同于裁判员尾管，但其目的是最大限度地减少安装造成的额外损失。本航空航天推荐规程（ARP）描述了飞机排气系统设计中要考虑的物理、功能和性能接口。

Turbine engines installed in rotorcraft have an exhaust system that is designed and produced by the aircraft manufacturer. The primary function of the exhaust system is to direct hot exhaust gases away from the airframe. The exhaust system may consist of a tailpipe, which is attached to the engine, and an exhaust fairing, which is part of the rotorcraft. The engine manufacturer specifies a baseline "referee" tailpipe design, and guaranteed engine performance is based upon the use of the referee tailpipe and tailpipe exit diameter. The configuration used on the rotorcraft may differ from the referee tailpipe, but it is intended to minimize additional losses attributed to the installation. This Aerospace Recommended Practice (ARP) describes the physical, functional, and performance interfaces to be considered in the design of the aircraft exhaust system.
