热交换器系统500布置在飞行器的涡轮喷气发动机附近,并且包括热交换器502。涡轮喷气发动机通过挂架固定到机翼结构,并且热交换器502位于挂架和挂架整流罩之间。
通过第一供应管504向热交换器502供应热空气,该第一供应管分别通过第一阀510和第二阀512从涡轮喷气发动机的高压级506或在中压级508处放出热空气。第一供应管504还包括调节阀514,其使得能够调节热交换器502的入口处的压力。

EP-A-0 934 876、US-A-2012/045317和WO-A-2018/002855公开了现有技术的推进系统。
实际上,涡轮喷气发动机的尺寸由于需要增加旁通比和总压力比而增大。由于涡轮喷气发动机的这种增大,分配给热交换器502的空间减小,并且热交换器502的排气靠近机翼的前缘,导致了对边界层的扰动。

具体实施方式
在以下描述中,涉及位置的术语是参照处于正常飞行位置中的飞行器而言的,即,是如图1所示的,并且位置“前”和“后”是相对于涡轮喷气发动机的前部和后部而言的。
在下文描述中,并且按照惯例,X是涡轮喷气发动机的纵向轴线,其平行于飞行器的纵向轴线;Y是横向轴线,当飞行器在地面上时,其是水平的;并且Z是垂直轴线,当飞行器在地面上时,其是垂直的;这三个方向X、Y和Z相互正交。
图1示出飞行器10,其包括机身11,在机身的各侧上紧固有机翼13,机翼13支撑至少一个推进系统15,推进系统在图3中示出并且包括挂架12和涡轮喷气发动机70。挂架12紧固在机翼13下方,并且支撑涡轮喷气发动机70,涡轮喷气发动机通常包括压缩级72和风机管道74。挂架12包括主结构50,主结构在其上部处紧固至机翼13的结构,并且通过不同的紧固点支撑涡轮喷气发动机70。主结构50布置在涡轮喷气发动机70上方,并且其前缘在风机管道74内附连到涡轮喷气发动机70。
压缩级72包括高压级206和中压级208。例如,在41000英尺的巡航条件下,205℃下的中间压力为35磅/平方英寸(psia),517℃下的高压为174磅/平方英寸。
飞行器10包括空气管理系统,例如空调系统和/或除冰系统。
推进系统15还包括发动机短舱14,其包括围绕涡轮喷气发动机70的整流罩76,以及围绕主结构50的挂架12的空气动力学整流罩。
图2示出本发明的热交换器系统200。
热交换器系统200包括主热交换器202,其包括主热供应连接部201、通过主热交换器202气动地连接到主供应连接部201的主热传递连接部203、主冷供应连接部205和通过主热交换器202气动地连接到主冷供应连接部205的主冷排出连接部207。
热交换器系统200包括供应管204,其连接到主热供应连接部201,并且其向主热交换器202供应热空气,并且其包括调节阀214,这使得能够调节热供应连接部201处的压力。
热交换器系统200包括通过第一阀210从高压级206放出热空气的高压管250。
热交换器系统200包括中压管252,其通过第二阀212从中压级208放出热空气。
高压管250和中压管252一起连接到调节阀214的入口。
热交换器系统200包括主供应管216,其连接到主冷供应连接部205,并向主热交换器202供应冷空气,并且从涡轮喷气发动机70的风机管道74放出冷空气。主供应管216还包括主调节阀218,其调节引入主热交换器202中的冷空气的量,以调节离开主热交换器202的热空气的温度。
热交换器系统200包括连接到主冷排出连接部207的排出管220。在已经通过主热交换器202之后,已经被加热的冷空气通过排出管220排放到外部。
热交换器系统200包括连接到主热传递连接部203的传递管222。在已经通过主热交换器202之后,已经被冷却的热空气通过传递管222引导到空气管理系统,例如空调系统或除冰系统。
热交换器系统200包括温度传感器223和控制单元224,温度传感器223测量通过传递管222离开主热交换器202的热空气的温度,控制单元224根据由温度传感器223测量的温度和通过传递管222离开主热交换器202的热空气的期望温度来控制各阀。
主热交换器202在此具有交叉流动,即,热空气和冷空气沿着两个总体上垂直的方向进入主热交换器202和离开主热交换器202。但是在另一实施例中,热空气从供应管204通过主热交换器202到传递管222的通过沿着第一传递方向发生,而冷空气从主供应管216通过主热交换器202到排出管220的通过沿着平行于第一传递方向、但是方向相反的第二传递方向发生。
热交换器系统200还包括副热交换器230,副热交换器230连接在第一阀210和高压管250上的调节阀214之间。
副热交换器230包括副热供应连接部231、通过副热交换器230气动地连接到副供应连接部231的副热传递连接部233、副冷供应连接部235和通过副热交换器230气动地连接到副冷供应连接部235的副冷排出连接部237。

副调节阀234也受控制单元224控制。
将热交换器分成主热交换器和副热交换器导致主热交换器202的尺寸减小,并且该主热交换器202在减小的空间中的集成更容易。
主热交换器202针对中压级208确定尺寸,并且一旦使用高压级206,副热交换器230就用于对主热交换器202进行补充,并且每个热交换器202、230具有其自己的冷空气入口216、232以及其自身的调节阀218、234,用于独立地调整冷空气流量。
对来自中压级208的热空气的冷却由主热交换器202进行,并且引入在主热交换器202中的冷空气的量受主调节阀218控制,以实现目标出口温度。
当从高压级206放出空气时,副调节阀234受控制为一旦主调节阀218完全打开就打开,并且在副热交换器230中的空气流量受副热调节阀234调整,以实现目标出口温度。如果排出温度变得太低,或如果系统被切换回到中压级208,则副调节阀234关闭,并且主调节阀218重新取得对温度控制的控制。
在图2所示的实施例中,副换热器230具有交叉流动,但是在另一未示出的实施例中,它可以具有反向流动。
图3示出了推进系统15的处于其环境中的热交换器系统200。
主热交换器202位于主结构50上方且在风机导管74中,而副热交换器230位于主结构50下方且在风机导管74中。更确切地说,主热交换器202位于挂架与挂架整流罩之间。
主结构50包括窗口,供应管204穿过该窗口以将其自身与高压管250和中压管252连接。
在图3所示的实施例中,调节阀214也设置在主结构50下方。
主调节阀218和副调节阀234在此采取包括门的斗形部的形式,该门可在打开位置和关闭位置之间移动,在打开位置中它不会堵塞斗形部,而在关闭位置中它会堵塞斗形部,从而调节由所述斗形部所捕获的冷空气的量。
门是马达驱动的以确保其运动,并且每个马达均由控制单元224控制。每个门用作阀。
各个斗形部定向为使得能够捕获在风机管道74中循环的冷空气。
新实施方式允许具有低放出空气侧压降的主热交换器的设计。由于输送到起动器涡轮的较高压力,对空调组件包的较高入口压力使使得该组件包以较少的冲压空气运行并因此减少了引起的冲压阻力以及中压级端口位置的挑战,使用改善发动机特定燃料消耗的较低压缩机级,这种较低的压降允许改进发动机起动性能。
