Air Crash And Pressure

Abstract

This paper studies hat air crash would be caused by the difference of pressures between outside and inside of passenger's cargo. Such difference of pressures can break the window or door and thus make the plane to crash. In order to calculate the pressure outside passenger's cargo, this paper set up and solves the solution of three type equations: A "w -T eq.", B "w -P/eq." and C"J -P/eq.". The A type is the base. It states that the derivative of wind speed respect to time proportions to the derivative of temperature respect to track (space). The A's solution obtained by method of separating variables has been checked by weather forecasting, by dimensional check, and by other model check. The solutions of B and C can be obtained directly from A. Missing plane MH370 has been used as an example to show the calculation of pressure outside the passenger's cargo. This paper would be referenced to pilot, administrator, engineer, scientist, teacher and student.
