| The aircraft load calculation implies determination of the loads acting on the aircraft structure for flight maneuvers, flight in turbulence, landing and ground handling conditions. The research of load calculation is very important for flight safety of the civil aircraft. The software design that can be used in all kinds of civil aircraft is a very important work since many kinds of load calculation conditions meeting the requirements of the airworthiness are very complicated.Taking into account of the structure distortion, the theory and method of load calculation is researched from the perspective of engineering and airworthiness in this paper. The presented theory and method of load calculation is suitable for all kinds of civil aircraft. The load conditions and the initial parameters appropriated to the load calculation are determined according to the requirement of airworthiness. Meanwhile, an aircraft load calculation software-ALCP is accomplished in accordance with the method of load calculating and the requirement of airworthiness. The correctness of the developed software is checked with the load calculations of Y7L and MA60 aircraft. The results given in this paper show that the software is suitable for all-purpose of the load calculation and all kinds of civil aircraft. |
