PURPOSE: An elaboration load calculating method of an interior armament cover door and a computer-readable recording medium which records a program for the same are provided to revise an elaboration load value of the interior armament cover door by calculating factors of an extensional wave and an impulse wave in which a speed of the aircraft affects the interior armament cover door in case a speed is greater than or equal to Mach 0.9. CONSTITUTION: An elaboration load of an interior armament cover door by the act state of an aircraft in the point of view of an electrical body is calculated using a three dimensional panel method (S101). A speed of the aircraft is compared with a predetermined value (S102). If the speed of the aircraft exceeds the predetermined value, factors of an extensional wave and an impulse wave in which a main wing of aircraft affects the interior armament cover door is calculated by the speed of the aircraft (S103). The elaboration load of the interior armament cover door is revised by applying the factors of the extensional wave and the impulse wave (S104). [Reference numerals] (AA) Start; (BB) Yes; (CC) End; (S101) Elaboration load of an interior armament cover door for an aircraft's certain operation mode from the point of view of an electrical body is calculated using a three dimensional panel method; (S102) Is the aircraft's speed faster than a predetermined value in the operation mode ?; (S103) Impact of the shock wave and expansion wave on the armament cover door is calculated at the aircraft's speed; (S104) Elaboration load calculated in the S101 step are corrected based on the impact of the shock wave and expansion wave |
