| Abstract: | The theory and method of ground based scrubbing inerting technology of unmanned aerial vehicle fuel tank were proposed.CFD method was used to study the feasibility of using ground based scrubbing inerting technology to reduce the oxygen volume fraction in fuel tank and keeping the fuel tank inert under the ground and flight conditions.Volume of fluid（VOF） two-phase flow model and custom mass transfer equation were applied to calculate the variation of oxygen volume fraction in fuel tank under different initial oxygen volume fraction and fuel load.The results indicated that the oxygen volume fraction in fuel tank ullage increased with the increase of initial fuel load and initial oxygen volume fraction at the same flight time.When the initial oxygen volume fraction was no more than 2% and the initial fuel load was no more than 50%，the oxygen volume fraction in fuel tank was kept less than 9%，up to the requirements of military aircraft fuel tank inerting.This study can provide a reference for the design of boundary condition of ground based scrubbing inerting of unmanned aerial vehicle fuel tank. |
