The dynamic pressures at a distance of 500mm away from the spout for the aircraft tire burst jets were measured in the aircraft main landing gear. The dynamic pressures were treated for equivalent static pressures while the distributions of the equivalent static pressures were simulated by linear and cubic spline interpolation functions based on MATLAB software. The results showed that the equivalent static pressure close to the middle region of the sector is relatively large at the same distance from the spout. The distributions by linear interpolation are more uniform than cubic spline interpolation, but the results from the cubic spline interpolation are more rounded than the other. The equivalent static pressure less 500mm away from the spout was obtained by the interpolations. Moreover, the equivalent static pressures are usually higher by cubic spline interpolation than linear interpolation.
