The Simulation And Safety Indicators Analysis Of Aircraft Catapult

This paper is the simulation study of aircraft carrier catapult’s take-off under different conditions and the different impacts on aircraft carrier catapult take-off by various environmental factors. The simulation results are analyzed by carrier-based aircraft catapult takeoff safety boundary conditions, mainly around the following work in several ways. The main contents of this study are as follows:1. On the basis of the principle of carrier-based aircraft catapult takeoff and process analysis, build and carrier-based aircraft catapult takeoff systems and equipment related to the mathematical model, by carrier-based aircraft catapult staging process to consider the dynamic model, landing gear projecting model, thermodynamic model within catapult reservoir steam cylinder and cylinder as well as the mathematical model launch valve, and then build aircraft carrier catapult take-off process of environmental models, including the establishment of aircraft carrier deck sports model and sea state model, in establishing these systems on the basis of the model of development and design of aircraft carrier catapult simulation systems.2. On the basis of the principle of carrier-based aircraft catapult takeoff and process analysis, build and carrier-based aircraft catapult takeoff systems and equipment related to the mathematical model, by carrier-based aircraft catapult staging process to consider the dynamic model, landing gear projecting model, thermodynamic model within catapult reservoir steam cylinder and cylinder as well as the mathematical model launch valve, and then build aircraft carrier catapult take-off process of environmental models, including the establishment of aircraft carrier deck sports model and sea state model, in establishing these systems on the basis of the model of development and design of aircraft carrier catapult simulation systems.3. According to the actual test conditions and two chapters catapult model, in contrast to the difference between the quality of the car and aircraft carrier catapult the case, by the design quality car simulation model to analyze the different weights of different terminal velocity ejection of quality car catapult takeoff process steam pressure within the cylinder,cylinder reservoir steam vapor pressure curve emission valve opening displacement quality vehicle acceleration and speed analysis to meet the weight, the speed at the end of the catapult launch valve variation and acceleration loads and other security constraints, etc. factors affecting the boundary conditions.4.The use and development of carrier-based aircraft catapult simulation system,simulation of different carrier aircraft weight, different from the ship speeds at different eccentric state aircraft carrier catapult takeoff trajectory and rules-based aircraft analysis and subsidence analysis to meet weight load under acceleration boundary conditions and other security constraints, ejection end speed and eccentricity factors in determining the safety of the boundary conditions on the basis of further analysis of the force of the front landing gear.And analyzes the carrier-based aircraft catapult takeoff dynamics of each mass unit analyzed the optimal length of the remaining deck.5. The use and development of carrier-based aircraft catapult simulation systems,simulation of the remaining aircraft carrier deck length, carrier-based aircraft quality, deck wind, motion, and various parameters on carrier-based aircraft catapult takeoff trajectory influence the final design of the an optimal length of the remaining deck to ensure the normal carrier aircraft catapult takeoff. Catapult takeoff on a certain type of carrier-based aircraft are simulated, and the results are analyzed, and the security indicator is based on carrier-based aircraft from the ship’s sinking amount and angle of attack and other indicators of various factors analyzed above.
