چکیده انگلیسی

The flight safety is threatened by the special flight conditions and the low speed of carrier-based aircraft ski-jump takeoff. The aircraft carrier motion, aircraft dynamics, landing gears and wind field of sea state are comprehensively considered to dispose this multidiscipline intersection problem. According to the particular naval operating environment of the carrier-based aircraft ski-jump takeoff, the integrated dynamic simulation models of multi-body system are developed, which involves the movement entities of the carrier, the aircraft and the landing gears, and involves takeoff instruction, control system and the deck wind disturbance. Based on Matlab/Simulink environment, the multi-body system simulation is realized. The validity of the model and the rationality of the result are verified by an example simulation of carrier-based aircraft ski-jump takeoff. The simulation model and the software are suitable for the study of the multidiscipline intersection problems which are involved in the performance, flight quality and safety of carrier-based aircraft takeoff, the effects of landing gear loads, parameters of carrier deck, etc

مقدمه انگلیسی

Ski-jump takeoff is one of the main takeoff modes for a carrier-based aircraft. Compared with catapult launch, it takes longer time on deck-running, acquires lower speed at ramp exit and greater effects by the aircraft carrier motion, wind field disturbance and launching time. Consequently it is important to take account of those factors comprehensively. From the viewpoint of system engineering, it is necessary to build an integrated system simulation model considering all the kinds of important influencing factors. This model brings about theoretical and practical significance not only to the research of flight dynamic problem referring to carrier-based aircraft, but also to the analysis of multidiscipline intersection problems including the suitability of carrier and aircraft, the motion coupling of deck, aircraft body and landing gears, as well as the safety of carrier-based aircraft takeoff or landing, etc. Many studies on the simulation of ski-jump takeoff process have been developed recently, including modeling of carrier-based aircraft motion, modeling of aircraft carrier motion and modeling of wind field disturbances, etc.1, 2, 3, 4 and 5 Particularity and complexity of the physical system make the research difficult on system modeling and simulating.6 and 7 Much work about modeling of the complete system needs to be carried out so far. Based on the latest researches of simulation modeling of ski-jump takeoff, this paper has built an integrated system simulation model taking account of multi-motion-body coupling between carrier, aircraft and landing gears, as well as the wind field induced by the aircraft carrier, the command decision on deck, and the control policy of pilot.

نتیجه گیری انگلیسی

The simulation modeling of carrier-based aircraft ski-jump takeoff is complicated. This paper builds the relatively complete system model of carrier-based aircraft ski-jump takeoff to resolve the problems of the coupling among multi-motion bodies and flight environment, as well as the problems of the cooperative instructions control. This system model takes into account three main effects: the coupling of carrier, aircraft body and the landing gears; the influences on the carrier motion by sea state and on the flight by the induced wind field; the influences on the aircraft flight by the cooperative instructions control among deck commanders and pilot. Two simulation examples show that the system model can describe the dynamic characteristics of all the movement bodies reasonably. It has practical significance for the multidisciplinary intersect problem in the design of carrier deck, design of landing gears and aircraft body. This system model can be used to analyze the influencing factors of flight safety comprehensively, such as flight environment, human decision-making control, etc., which is supposed to play an important role in flight training.
