Thrust force measurement of an engine

Client

Aircraft or rocket designer/manufacturer responsible for the integration, characterization, and development of the turboshaft engine.

Problem, challenges

The development of the engine integrated into the aircraft or rocket is a critical step for validating the performance of the aircraft (maximum load, performance, consumption/efficiency, etc.). Development is carried out on a dedicated engine test bench, instrumented for measuring fuel consumption, oxidizer, temperatures, and thrust force. Challenges:

• Precision: fine precision enables the identification of the final percentage points of required efficiency
• Repeatability: since development relies on multi-parameter experimental designs, excellent repeatability is essential
• Resistance to severe stresses (vibratory, thermal)

PM Instrumentation Solution

For "guided" assemblies, with compensation for radial forces and moments: the sensor from the 1000 series offers the robustness/precision compromise for capacities that can reach several hundred tons.

For "floating" assemblies, where the engine is suspended from the thrust sensor, 3- and 6-axis multi-component sensors are ideal for capturing radial forces as well as moments. Reducing these forces will improve propulsion efficiency and mechanical durability.

Customer results and benefits

Thanks to their precision, stability, and repeatability, the measurements are directly usable by development engineers. Simplified mechanical integration reduces the duration of test campaigns.
