中国无人机（UAV）可能用于引导弹道导弹
Chinese UAV May Conduct Targeting for Ballistic Missiles

Posted by David A. Fulghum at 7/1/2011 8:25 AM CDT

=====================================================



The latest unmanned aircraft pictures from China have revealed a new UAV with joined wing and tail that could considerably increase range and payload and produce better handling at high altitudes. The unmanned aircraft may be undergoing near-field radar-cross-section or antenna testing since Internet images show it on the ramp with the landing gear shrouded.

U.S. analysts are already suggesting that the new Chinese UAV design -- with its 60,000-ft. cruising altitude, 300-mi. radar surveillance range and, possibly, lower radar reflectivity if made from the right composites -- could serve as the targeting node for China’s anti-ship ballistic missiles.

Meanwhile, Chinese industry is working on active electronically scanned array (AESA) radar designs and is shopping in the international market for small, powerful, airborne fighter-size and smaller AESAs.


中国最新的无人机照片显示某种新型UAV采用了机翼和尾翼相连的设计，可极大地增加航程，载荷并具备更好的高空操纵性。因为网络照片显示该无人机被架起并且起落架部分被遮盖，可能正在进行模拟雷达截面反射测试或天线测试。
美国分析人士早就暗示中国新型UAV的设计可用于其反舰弹道导弹的目标引导节点。该机巡航高度60000尺（18000米）， 雷达监视距离300英里（约480公里）并可能使用了合适的复合材料从而具有低雷达反射率。

同时，中国军工还在设计AESA雷达并正在国际市场采购小型大功率战斗机用或更小的AESA。



Boeing used a joined-wing configuration in its contribution to the USAF Research Laboratory’s SensorCraft project, aimed at developing an aircraft capable of carrying an airframe-integrated, 360-deg.-coverage, high-resolution radar and remaining on station for 30 hours at 2,000 nm range. A small, low-speed free-flight model known as VA-1, with a 14-foot wingspan, was completed by AFRL in 2003 and test-flown. A model of Boeing’s Joined Wing SensorCraft was tested last year in NASA Langley’s Transonic Dynamics Tunnel under the USAF’s Aerodynamic Efficiency Improvement (AEI) program.

The new Chinese UAV was likely photographed on the Chengdu Aircraft Corp.’s ramp. Photographs emerging from Chinese Internet sources show a new design featuring a novel joined-wing layout. In the same size class as the General Atomics-Aeronautical Systems Inc. Avenger, and powered by a single turbofan engine, the new UAV is the most advanced Chinese design seen to date and the largest joined-wing aircraft known to have been built.

The company also makes the J-10 strike fighter, the J-20 stealth fighter prototype and a Global Hawk-like maritime reconnaissance UAV called the Xianglong or Soaring Dragon, which flew in December 2009. CAC officials say it has a wingspan of 75 ft., 45-ft. length and a cruise altitude of 55,000-to-60,000 ft., Chinese sources credited it with a 7500 kg (16,500 lb) take-off weight and 3800 nm range. The forebody is bulged to accommodate a high-data-rate satcoms antenna.


波音曾经在其为美国空军研究所的SensorCraft项目提供过联翼式结构方案。计划开发一种飞机，能携带固定于机身上的，360°全方位的，高分辨率雷达，并且能在2000海里（约3700公里）范围停留30小时。一个小型低速自由飞行模型（VA-1），翼展4.26米，由空军研究所AFRL于2003年完成并试飞。去年在NASA "兰利"跨音速动力学风洞试验了波音的SensorCraft联翼模型，该项目属于美国空军空气动力学效能改良计划 （AEI）。

这款新型中国UAV看起来被摄于成飞的跑道。中国网络资源的照片显示其采用了新颖的联翼布局设计。其尺寸和GA-ASI公司的复仇者（捕食者C款，http://www.ga-asi.com/products/aircraft/predator_c.php）同一级别，使用单一涡扇引擎。该新型UAV是至今所见的中国最先进设计并也是当前制造出的最大的联翼飞机。

成飞也生产J-10战斗机，J-20隐形战斗机原型机。
还有类似全球鹰的巡海UAV，名叫翔龙，并于2009年12月飞过。（大哥你照片上的这款才是翔龙啊，有汉字刷着呢。同时求解跨海夜叉机）。CAC官员说该机翼展75英尺（约23米），机长45英尺（13.7米），巡航高度55000-60000英尺（16764-18288米）。来自中国的资料确信其起飞重量7500kg，航程3800海里（约7000公里），前机身鼓起以容纳高数据速率的卫星通信天线。


Joined wings – a subset of closed-wing systems – comprise a sweptback forward wing and a forward-swept aft wing. In the new Chinese UAV, (as in many such configurations,) the rear wing is higher than the forward wing to reduce the impact of the forward wing’s downwash on the rear wing’s lifting qualities. The rear wing has shorter span than the front wing and its downturned tips meet the front wing at a part-span point.

Advocates of the joined wing claim that its advantages stem from the fact that the front and rear wings are structurally cross-braced. This allows higher aspect ratio while keeping down weight and staying within flutter limits. Higher aspect ratio reduces drag due to lift, and because the wings are both slender and short-span (relative to a single wing with equivalent lift) the wing chords are short, which makes it easier to achieve laminar flow. The joined wing can also reduce trim drag.


联翼属于闭合翼系统的一种，包含后倾前翼和前倾尾翼。在中国新型UAV上（和其它很多设计类似），后翼高于前翼来减小前翼产生的下降气流对后翼升力的影响。后翼比前翼短，翼尖下延和前翼相连。

联翼的倡导者们声称其优点在于前后机翼结构上是牵拉支撑的。能大幅度减重并防止翼振。大幅降低升致阻力。而且因为其（和产生同样升力的单翼相比）翼型苗条，跨度短，翼弦短，更容易进入层流（即平流层，又称同温层）。还能降低配平阻力（trim drag）。
