摘 要
機(jī)翼是飛行器在飛行中可重新構(gòu)型的主要部件。在飛行中有目的地改變機(jī)翼外形(如機(jī)翼后掠、改變翼展和跨度等)，可以有效地增加機(jī)翼的效率。針對(duì)這個(gè)問(wèn)題，通過(guò)智能材料結(jié)構(gòu)與鉸鏈機(jī)械結(jié)構(gòu)相結(jié)合，設(shè)計(jì)并做出可變跨度機(jī)翼的仿真模型。使飛機(jī)的機(jī)翼可以根據(jù)飛行條件的不同來(lái)調(diào)整機(jī)翼的跨度。本文主要是通過(guò)采用改變飛機(jī)機(jī)翼的跨度的方式，來(lái)達(dá)到改變飛機(jī)速度和機(jī)動(dòng)性能的目的。在不考慮外界因素的影響下，應(yīng)用Fluent軟件對(duì)機(jī)翼進(jìn)行動(dòng)力學(xué)仿真分析。測(cè)出在不同跨度、馬赫數(shù)和攻角下機(jī)翼升力、阻力、升力系數(shù)和阻力系數(shù)的變化。由分析結(jié)果可知和該設(shè)計(jì)方案可行。飛機(jī)根據(jù)不同飛行條件調(diào)整機(jī)翼參數(shù)，為可變翼巡航導(dǎo)彈、艦船潛艇等軍用武器的設(shè)計(jì)提供了參考依據(jù)和設(shè)計(jì)方向。

Abstract
Destination while flying wing to change shape (such as the swept wing, wingspan and the curvature change, etc.), can effectively increase the efficiency of the wing. Among them, the change in wingspan and wing area of the most prominent effect. To address this issue, the adoption of Smart Materials and Structures and hinge combination of mechanical structure, design and make a variable span wing aircraft simulation model skeleton. Wing aircraft flying under different conditions of deformation through the action of the control device to adjust the span of the wing skeleton. The subject is changed through the use of aircraft wing-span of the way to achieve change in aircraft speed and mobility purposes. Without taking into account the influence of external factors, the application of the rectangular wing Fluent software framework for dynamic simulation analysis. Measured at different span, Mach number and angle of attack of wing lift, drag, lift coefficient and drag coefficient changes. We can see from the results of the analysis and the design is feasible. Depending on conditions of aircraft flight parameters to adjust the wings for the variable wing cruise missiles, submarines, ships and other military weapons designed to provide a reference for the direction and design.
