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。在一种构型中，涡轮喷气发动机用于推进。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（500 N推力）进行地面推力测量。一个实验装置将被设计，仪器，并建立了一个目的。发动机支架（和车架）的设计应能减轻任何横向运动。必须注意光滑的进气道、具有恒定进气压力的试验段、也允许适当推力测量的发动机支架以及用环境空气冷却气体的排气系统。最终，这一初步研究将导致未来的合作，以测试这些燃气轮机使用模拟海拔测试设施，在可能的合作与NRC。

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.
