Design of an Aeronautical Engine Test Stand 2000-01-3256
This work is about design of a static test stand for aeronautical engines with propeller. The objective is measure propeller thrust and engine torque (two degree of freedom). The design covers system specifications, structural design, dynamic analysis, instrumentation project and tests and calibration procedures. It specifies maximum forces to be measured, maximum propeller diameter and types of tests, as constant rotation, acceleration and robustness. Also, it is presented design recommendations covering structural loads, joint types, engine accessories and minimum instrumentation. A stand sketch is showed and calibration procedures were discussed. To forecast the system resonance frequency and dynamic behavior, plots of stand-sensors system dynamic response were presented. This test stand allows measuring propeller static efficiency and engine-propeller system static propulsive curve.
