3D打印的下一代火箭发动机
3D 打印的下一代火箭发动机文/松堂▲ 3D 打印可以在发动机内部形成复杂的管路，这是传统制造很难做到的一般来说，如果要把两个用不同材料制成的零件结合在一起，就需要用 上焊接等手段，连接部分总是会存在机 械失效的风险，例如火箭发动机里用的点火器。
ASA 马歇尔飞行中心的科研人员 尝试着用3D 打印来解决这个问题。
他 们用辂银铁合金和铜锌合金材料，打印出了一种高25.4厘米、直径17.8厘米的部件。
用传统方法，这个部件要用4 个不同的部件铜焊在一起；而用3D 打 印，可以一次性解决。
制造完成后，这个点火器经历了33次测试，模拟了从首次点火到高空 二次点火的不同工况。
其中一次工作 了 10秒，其余都工作了 5秒；最低工作温度-1579,最高工作温度达到12049。
实验结束之后，阿拉巴马大学的研究人员把点火器纵向剖开，发现两种合金结合得很好，之间有一个相当大厚度的互扩散层，比传统的焊接工艺效果一点都不差。
马歇尔中心工程部的有一种说法认为，当人们拥有一 种新技术之后，初期往往用来做一些传统的工作。
当充分掌握之后，往往会发 明出全新的理念，对整个学科产生颠覆性的作用。
3D 打印技术就是其中的一个例子。
便宜了一半的发动机火箭发动机的结构复杂，零件外 形不规则，在传统的金属切削工艺下，有些零件的制造非常困难。
3D 打印首先用在了这些方面。
负责人认为，3D 打印技术至少能把未来发动机的制造成本降到今天的三分之—,制造周期减少一半。
事实证明，马歇尔中心的判断是 有道理的。
在美国主要发动机制造商之一的阿罗杰特公司，3D 打印技术的46 I SPACEEXPLORATION▲测试中的3D 打印发动机，火焰看上去很稳定▲ 3D 打印的发动机外观更加简洁引入让复杂零部件的制造工时减少了50%以上。
在联合发射联盟公司正在研制的“瓦尔肯”火箭中，上面级就打算采用 阿罗杰特公司的RL10C-X 发动机。
联合发射联盟公司多年来一直因为发射服务价格太高而为业界所诟病，因此在“瓦尔肯”的研制中，要求大幅度降低成本, 但不能影响到可靠性和性能。
朝鲜版“关岛快递”——“火星”12中远程弹道导弹
朝鲜版“关岛快递”——“火星”12中远程弹道导弹作者：陈泽慧来源：《坦克装甲车辆》 2017年第23期朝鲜在今年4月15日的“太阳节”阅兵式上首次公开亮相“火星”12中远程弹道导弹。
5月14日、8月29日和9月15日，朝鲜分别进行了“火星”12导弹的高弹道试验、低弹道试验和正常弹道试验。
导弹的实际飞行距离从787千米、2?700千米跨越到3?700千米，这三次试验为外界了解朝鲜导弹技术的发展水平提供了难得的资料。
发展概况“火星”12导弹首次亮相时曾被误认为是“火星”13（KN-08）导弹的改进型。
这是因为从外形上看，“火星”12的弹头设计与“火星”13导弹一模一样，相似的气动外形设计很容易让人感觉这是一枚去掉第三级的“火星”13。
在仔细观察这枚新导弹后，可以发现，“火星”12的电缆槽和加强肋并非像“火星”13那样一直延伸至弹体尾部，而是在离发动机底部喷口约1.7米处终止了，这意味着新导弹采用的不是像R-27潜射导弹或“火星”10/13那样的潜入式发动机设计，而是和“火星”5/6/7一样发动机舱与推进剂贮箱分开。
发动机安装在外形类似苏联SS-5导弹的筒裙体尾段内部，外部没有任何弹翼，尾段壳体上也开有便于使用操作的舱口。
“火星”12导弹的设计如同SS-5导弹的缩小版。
而朝鲜之所以能够研制出射程与SS-5/R-14导弹相当，但是重量却只有其三分之一多一点的“火星”12，原因就在于朝鲜开发出了比冲更高的新型液体火箭发动机。
值得一提的是，在此之前，朝鲜用来发射“光明星”系列卫星的“银河”3火箭的第一级弹体直径与SS-5导弹相当，不过即便是并联了4台“火星”7导弹发动机，由于其比冲较低，整体推力还是不如SS-5导弹。
而且即使在“银河”3火箭一级基础上开发射程覆盖关岛的新导弹，80吨左右的弹体重量也不利于在朝鲜多山地形条件下机动作战，庞大的弹体也更容易被敌方发现，生存力低下。
这也是朝鲜以高比冲的“火星”10发动机为基础开发弹体重量只有40吨左右的“火星”13洲际导弹的原因之一。

Note that the Pin marked “J1” on the Embedded Module must be matched with the Pin marked “J1” on the EM-1220-DK; and the Pin marked “J2” on the Embedded Module must be matched with the Pin marked “J2” on the EM-1220-DK. Be careful wheninstalling the board to avoid damaging the pins.LED IndicatorsThe following table explains the function of the LED indicators located on the EM-1220-DK.LED Name LED Color LED FunctionReady Green Power is on and system functions normally.P1, P2 (Tx) Green Serial port 1, 2 is transmitting data.Off Serial port 1, 2 is not transmitting data.P1, P2 (Rx) Yellow Serial port 1, 2 is receiving data.Off Serial port 1, 2 is not receiving data.Wiring RequirementsThis section describes how to connect the EM-1220 Development Kit to serial devices.You should heed the following common safety precautions before proceeding with the installation of anyelectronic device:Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must cross, make sure the wires are perpendicular at the intersection point.NOTE: Do not run signal or communication wiring and power wiring in the same wire conduit. To avoidinterference, wires with different signal characteristics should be routed separately.Use the type of signal transmitted through a wire to determine which wires should be kept separate. The rule of thumb is that wiring that shares similar electrical characteristics can be bundled together.Keep input wiring and output wiring separate.It is advisable to label the wiring to all devices in the system.Be sure to disconnect the power cord before installing and/or wiring your EM-1220 Development Kit.Connecting the PowerYou may use the 3-pin terminal block for connecting the power. The power input range of the EM-1220-DK is from 12 to 48 VDC. If the power is properly supplied, the “Ready” LED will glow a solid green after a 25 to 30 second delay.Grounding the EM-1220 Development Kit Grounding and wire routing help limit the effects of noise due to electromagnetic interference (EMI). Run the ground wire from the ground screw to the grounding surface prior to connecting devices.Serial Ports and Pin AssignmentsThe EM-1220 Development Kit has 2 software-selectable serial ports. If you would like to connect to a serial device, use male DB9 connectors. The ports can be configured for RS-232, RS-422, or RS-485 by software.Refer to the Software User’s Manual for details. Pay attention to the cable length for the various serialcommunication standards. Refer to the following figure for the pin assignments of the DB9 connector.Male DB9 Port Pin RS-232 RS-422 4-wire RS-485 2-wire RS-4851 DCD TxDA(-) TxDA(-) –2 RxD TxDB(+) TxDB(+) –3 TxD RxDB(+) RxDB(+) DataB(+)4 DTR RxDA(-) RxDA(-) DataA(-)5 GND GND GND GND6 DSR – – –7 RTS – – –8 CTS – ––Console Ports and Pin AssignmentsThe serial console port on the EM-1220-DK is a 4-pin pin-header RS-232 port, which support TxD, RxD, and GND signals.

Connect one end of the Ethernet cable to the Development Kit LAN port and the other end of the cable to the Ethernet network. The LAN ports use 8-pin RJ45 connectors. See the following diagram for the pinouts.8-pin RJ45Pin Signal1 ETx+2 ETx-3 ERx+4 –5 –6 ERx-7 –8 –SD SocketThe EM-1220 Development Kit provides an internal SD socket for storage expansion. The socket allows users to use a Secure Digital (SD) memory card compliant with the SD 1.0 standard for adding up to 1 GB ofadditional memory space. Plug the SD card directly into the socket. Remember to press the SD card first if you want to remove it. Note that the SD will not work if you enable the GPIO function. Refer to the section about the EM-1220’s SD function to see a table that describes the SD card interface.Reset ButtonPress the Reset button on the EM-1220-DK continuously for at least 5 seconds to load the factory defaultconfiguration. After the factory default configuration has been loaded, the system will reboot automatically. We recommend that you only use this function if the software is not working properly and you want to load factory default settings. To reset an embedded Linux system, always use the software reboot command />reboot to protect the integrity of data being transmitted or processed. The Reset button is not designed to hard reboot the EM-1220 Development Kit.。
