The Research on Flow Resistance Characteristics of Aircraft Pipes with Different Bending Radius
As the weight and flight speed of the aircraft continue to increase,the transmission load and response speed are also increasing.However,excessive flow resistance can reduce the transmis-sion efficiency of the system,while pressure loss can lead to increased system temperature.It is nec-essary to minimize the pressure loss during the medium flow process as much as possible.The article explores the influence of different bending radius on the flow resistance characteristics of pipes under various working media by AMESim.The results indicate that slow bending can alleviate hydraulic impact and effectively reduce the flow resistance of hydraulic system conduits.Choosing a reasonable pipe diameter and using a fluid with lower viscosity as the working medium are also beneficial for re-ducing flow resistance.For pneumatic system conduits,increasing the bending radius has no signifi-cant effect on reducing the flow resistance of the conduit.
