During wind tunnel testing of aircraft, the aerodynamic effects of jet engines are represented using one of two techniques. The vast majority of models use ‘Through Flow Nacelles’ (TFN), effectively open tubes, which do not represent any powered engine airflow. A small amount of more representative testing is achieved using Turbine Powered Simulators (TPS) to represent engine airflow, but this is expensive, cumbersome, and requires significant energy and fixed infrastructure to operate. A new generation of permanent magnet electric motors has recently been developed for the Formula 1 industry (primarily for kinetic energy recovery and power systems), which appear to have the power density necessary for the effective simulation of scaled jet engines. This project aims to further develop these motors, the associated test control infrastructure, and techniques, for successful aerospace wind tunnel testing. The aim is to deliver the representative effect of TPS techniques, whilst eliminating the associated fixed infrastructure, by using electric motors instead of a turbine. The outcome sought is the more frequent generation of high fidelity data at lower overall lifecycle cost.

在飞机的风洞试验中，喷气发动机的空气动力效应是用两种技术之一来表示的。绝大多数型号使用“通流短舱”（TFN），有效地打开管道，不代表任何动力发动机气流。使用涡轮机动力模拟器（TPS）来表示发动机气流，可以实现少量更具代表性的测试，但这是昂贵的、笨重的，并且需要大量的能量和固定的基础设施来操作。新一代永磁电动机最近已被开发用于F1行业（主要用于动能回收和动力系统），其似乎具有有效模拟缩放喷气发动机所需的功率密度。该项目旨在进一步开发这些电机，相关的测试控制基础设施和技术，以成功进行航空航天风洞测试。其目的是通过使用电动机代替涡轮机来提供TPS技术的代表性效果，同时消除相关的固定基础设施。所寻求的结果是以较低的总体生命周期成本更频繁地生成高保真数据。
