Description

组合的混合火箭系统
相关中请的交叉引用
本申请要求于2003年3月28日提交的、申请号为60/458,296的美国临时专利申请的权益。
技术领域
本申请涉及一种混合火箭系统,其例如用于推进带机翼亚轨道航天器,但并不限于该应用。
背景技术
与固体燃料和液体燃料火箭相反,混合火箭发动机同时使用这两种燃料。也就是说,某种液体氧化剂例如氧化氮(N2O)被用来燃烧固体燃料。氧化剂被盛放在加压箱内,而固体燃料(例如HTPB、或端羟基聚丁二烯)则被铸在中空且通常是管形的燃烧室壳体或发动机的内壁上,其中所述燃烧室壳或发动机从氧化剂箱向后延伸,而终止于喉部和喷嘴。飞行员控制的阀门使氧化剂进入燃烧室壳体内,点火器(如火花或火焰型)启动燃烧。
发明内容
本发明涉及两个重要的改进。首先,涉及一种将火箭固定和安装到航天器机身或相关结构的简化方法;其次,涉及一种集成式发动机结构,该结构明显地限制了可能的漏泄路径,从而提高了可靠性和安全性。
本发明的混合火箭系统的特征在于,所使用的氧化剂箱具有圆柱形中部,该中部可以通过弹性粘合剂层而被粘合到航天器的内表面。延伸的固体燃料发动机壳以机械方式刚性固定到氧化剂箱的中后表面,该发动机壳的末端具有喉部和喷嘴。氧化剂箱对航天器的弹性粘合形成火箭系统的唯一支撑,而且不需要对于发动机壳的单独支撑。

图2是火箭部件的分解图;
图3是火箭的固体燃料发动机箱的前端的剖视立体图;
图4是发动机壳与氧化剂箱的连接处的局部剖视图;而
图5是氧化剂箱的局部剖视图。
具体实施方式
图1所示为一种混合火箭10,其安装在具有机翼的航天器的机身11内,该机身采用局部剖示出,机身11具有飞行员舱12。火箭10的主要部件是氧化剂箱14,其具有延长的圆柱形中部15,圆柱形中部15固定到机身的内表面17,该箱体具有后隔板(下文中描述),圆柱形的发动机19固定到该后隔板,发动机的末端有一喷嘴20。为清楚起见,图1中省去了可缩回的起落架和航天器机翼和尾部。
图5示出了氧化剂箱14的横截面图,该氧化剂箱具有相对薄(例如0.1至0.125英寸)的内衬22,该内衬是由环氧纤维玻璃预浸复合材料制成的。内衬被涂有环氧基体的石墨增强纤维层23所过度卷绕。增强纤维/环氧层的厚度在箱体圆柱形中部15处的厚度约为四分之一英寸,且朝着相对的箱体两端逐渐变厚到大约1至1/2英寸,在此处箱体与圆柱形的前凸缘26和后凸缘27(图5)接触并密封接合。
密封固定到前凸缘26的是前隔板29,前隔板闭合箱体的前端,但提供了有阀的入口(未示出)用以加载氧化剂。类似地密封固定到后凸缘27的是向前凸出的后隔板30,后隔板闭合箱体的后端。氧化剂输送阀和点火系统(未示出)安装在箱体内的后隔板上。
箱体的圆柱形中部15被圆柱形外罩32所覆盖,在一优选方式中外罩32是由大约十一片或十一层柔韧的纤维玻璃布制成的,这些粘合在一起的片被定向为相对于箱体的纵轴成45度角。外罩的内径略大于箱体中部的外径,使得一厚(约0.1英寸)层弹性粘合剂(由PRC Desoto制造的Proseal P5890,Class B是令人满意的)能够注入,从而将外罩粘合到箱体。
这种粘合在一起的外罩和箱体在航天器机身11的配套的内圆柱表面34内形成滑动配合,让一薄(约0.02英寸)层刚性粘合剂能够注入,从而将箱体和外罩固定到机身。例如Hysol 9396之类的粘合剂是令人满意的。箱体-外罩及外罩-机身的粘合形成航天器内火箭10的唯一支撑。
图4是发动机19对氧化剂箱后凸缘27和后隔板30的刚性连接的局部剖视图。发动机壳36具有大约0.1英寸厚的硅酚醛树脂(silicon-phenolic)内衬37,及大约0.3英寸厚的碳增强纤维外套38。固体燃料39被铸到发动机壳内,留下机壳中心线周围的开放部分。压铸的头部绝缘40形成在固体燃料的前方,且具有向前凸出的前端41,该前端与隔板30后端的配合曲率一致。机壳36的前端外扩,从而贴靠到圆柱形的钢楔43,此钢楔具有三角形的截面并具有前表面44,该前表面具有O形密封圈45,贴靠到后隔板30上外延的圆柱形凸缘46。
铝制压圈50具有向前和向外倾斜的锥形内表面51,该内表面套在发动机壳的前端上并紧靠凸缘46的后表面。若干个螺纹紧固件52延伸穿过压圈50、凸缘46、及凸缘27中的配合孔直到螺母53,以将那些部件紧密地夹在一起,从而将发动机壳刚性固定到氧化剂箱。额外的O形密封圈54被置于凸缘46和向前延伸的衬圈55中,衬圈55是与后隔板一体形成的。有孔的圆柱形管56固定到衬圈55,并在氧化剂箱内向前延伸以供作防荡板。
氧化剂箱装载有加压至700磅/平方英寸的含氮氧化物,在此压强下氧化剂是液体。加压箱的向外膨胀至少部分地被弹性粘合剂厚层所吸收,该厚层将箱体外罩粘合到机身,而且这个粘合剂层也吸收和减弱了发动机振动。
除去圆柱形中部15,氧化剂箱大体近似于一个球体,所提供的压力容器的强度足以支撑由点火后的发动机所施加的负载。这个强度使得发动机能以悬臂的方式从氧化剂箱的后端延伸,而不再需要来自机身的支撑。这种单一的连接方式让发动机(通常是一次性使用的部件)能够容易地更换,并可以放置不同长度的发动机,而且减少了可能的漏泄路径的数目。另外,在发动机支撑方面没有产生任何额外的重量,因为坚固的箱体/机身的安装结构就支撑了整个火箭系统。
