AI Technical Summary
The lack of mature ground test stand propeller thrust measurement technology for turboprop engines in the current technology leads to high test costs, long test cycles, and results that are easily affected by test stand equipment, making it difficult to accurately reflect the propeller thrust of the integrated propeller and generator.
Design a scaled-down test device for measuring propeller tension on a ground test stand for turboprop engines. The device includes a scaled-down test chamber, a scaled-down test stand, a scaled-down propeller, a scaled-down air intake, a rotating force balance, etc. The model is scaled down according to a set ratio. Combining similarity theory and a measurement and control system, the device simulates the engine air intake process and avoids equipment vibration interference.
It enables low-cost, short-cycle propeller thrust measurement, accurately assesses the thrust of propeller-generator integrated units, avoids interference from test bench equipment, and improves the accuracy and efficiency of measurement.
