Thrust and Emission Measurements of a Small Gas Turbine for Research Aerial Vehicles

庞巴迪公司一直在探索小型研究飞行器的发展。在其中一种配置中，涡喷发动机用于推进。除了排放测量(NOx、CO、CO2、HC和颗粒物)外，该公司还希望对小型燃气轮机进行地面推力测量(500 N推力)。将为此目的设计、测量和建造一个实验装置。发动机悬置(和车架)的设计应能减轻任何横向运动。必须注意平滑的进气口、具有恒定进气口压力的测试部分、允许适当的推力测量的发动机悬置以及与环境空气一起冷却气体的排气系统。最终，这项初步研究应该会导致未来的合作，可能与NRC合作，使用模拟高度测试设施来测试这些燃气轮机。

Bombardier Inc. has been exploring the development of small-scale research aerial vehicles. In one of the configurations, turbojet engines are used for propulsion. The company wishes to perform on-ground thrust measurements of small gas turbines (500 N thrust), in addition to emission measurements (NOx, CO, CO2, HC, and particulate matter). An experimental setup will be designed, instrumented, and built for the purpose. The engine mounts (and frame) should be designed to mitigate any lateral motion. Care must be taken regarding a smooth inlet, a test section with a constant inlet pressure, engine mounts also allowing a proper thrust measurement, and an exhaust system providing cooling of the gases with ambient air. Ultimately, this initial research should lead to future collaborations to test these gas turbines using simulated-altitude test facilities in a possible collaboration with NRC.
