The WuZhen-5 (WZ-5, also known as ChangHong-1) jet-powered unmanned reconnaissance aerial vehicle (URAV) was developed by Beijing Institute of Aeronautics (now Beijing University of Aeronautics & Astronautics, BUAA) based on the U.S. AQM-34N Firebee, but its ground control equipment is a Chinese indigenous design. The WZ-5 is China’s first operational URAV and entered service with the PLAAF in 1981. The improved variant WZ-5A was introduced in 1999. BUAA is currently developing a new model as the WZ-5's successor.

無偵（WuZhen）-5（WZ-5，也即是長虹（ChangHong）-1）噴氣式無人偵察機（URAV）由北京航空學(xué)院（現(xiàn)在北京航空航天大學(xué)，BUAA）基于美國AQM-34N型“火蜂”（Firebee）發(fā)展，但是它的地面控制設(shè)備是中國本國設(shè)計。WZ-5是中國第一種可操作的URAV并在1981年進入PLAAF服役。改良型WZ-5A在1999年推出。BUAA現(xiàn)在正在發(fā)展一種新的型號當作WZ-5的替代者。

The PLA shot down several AQM-34N Firebee URAV operated by the U.S. Strategic Air Command during their missions over China mainland and North Vietnam in the 1960s. At least one Firebee was recovered by the PLA in relatively good conditions. The uav was later carefully inspected by the Chinese engineers for possible reverse-engineering. In 1969 Beijing Institute of Aeronautics (now BUAA) took the lead to develop an indigenous optical-camera URAV based on the AQM-34N. The development programme consisted of three primary sub-systems: UAV airframe, WP-11 turbojet engine, and the ground control equipment.

在1960年P(guān)LA在中國大陸和越南北部上空擊落被美國操作正在執(zhí)行它們?nèi)蝿?wù)的幾架AQM-34N“火蜂”URAV。至少一架“火蜂”在相對完好情況下被PLA找回。UAV后來被中國工程師仔細檢查用于可能存在的逆向-工程。1969年在北京航空學(xué)院（現(xiàn)在BUAA）帶領(lǐng)下發(fā)展基于AQM-34N型的本國光學(xué)-相機URAV。發(fā)展計劃由三個主要的子系統(tǒng)所組成：UAV機身、WP-11渦輪噴氣發(fā)動機和地面控制設(shè)備。

Beijing Institute of Aeronautics (BIA) used parts recovered from the Firebee wreckages to assemble two prototypes for flight tests in 1972 and these flew successfully. An additional two prototypes using Chinese-made parts made their first flight successfully in 1976. BIA also set up a UAV design and research centre responsible for the development and manufacturing of the URAV. The Chinese-made Firebee known as WZ-5 passed its design certification test in 1978 and the URAV entered PLAAF service in 1981.

1972年北京航空學(xué)院（BIA）使用從墜毀“火蜂”回收的部件組裝了兩架原型用于飛行測試并成功飛行。另外兩架原型使用中國制造的部件在1976年成功進行了首次飛行。北京航空學(xué)院也建立一個UAV設(shè)計和研究中心負責(zé)發(fā)展和制造URAV。中國制造的“火蜂” 即是WZ-5在1978年通過了它的設(shè)計鑒定測試，而且URAV在1981年進入PLAAF服役。

The WZ-5 was reported to have taken part in the China-Vietnam border conflict in the 1980s and played an important role in collecting valuable military intelligence. A total of nine examples were built. BUAA began to develop an improved variant possibly known as WZ-5A in 1995 and the URAV made its first flight in 1999. The WZ-5A is fitted with a combined inertial and gps navigation system for improved accuracy.

WZ-5在1980年參加中國-越南邊境沖突并在收集有價值的軍事情報方面扮演重要角色?？倲?shù)九架樣機被制造。在1995年BUAA開始發(fā)展一種改良型可能即是WZ-5A并且URAV在1999年作了它的首次飛行。WZ-5A配備有一套組合慣性和GPS導(dǎo)航系統(tǒng)用于提高精度。

The WZ-5 has mid-mounted, swept-back wings with angular tips. The engine is a bulging jet on the belly with an oval air intake and round exhaust. The fuselage is round and tapered front and rear with a pointed nose and tail cone and a belly fin. The tail flats are high-mounted, swept-back with a swept-back and tapered fin. The WZ-5 was originally carried by the modified Tu-4 Bull bomber, and later by the Shaanxi Aircraft Company Y-8E (An-12 Cub copy) turboprop transport.

WZ-5采用中-置、后掠機翼。發(fā)動機在腹部凸起采用一個橢圓形進氣口和圓形排氣口。圓形機身和錐形前部和尾部采用一個尖形前鼻和尾錐和一個腹鰭。后掠上置尾垂翼連同一個后掠錐形尾平翼。WZ-5最初被經(jīng)過修改的Tu-4“公牛”轟炸機攜帶，稍后被陜西（Shaanxi）飛機公司Y-8E（An-12“幼狐”仿造型）渦輪螺旋槳運輸機。

During its mission, the WZ-5 UAV is first carried by its carrier aircraft to the target zone, and then released at the altitude between 4,000 and 5,000m. The UAV then automatically climb to its operational altitude of 17,500m. Once entering the target zone, the UAV flies under the autopilot, which is pre-programmed with flight parameters such as altitude, path, speed, duration and range. After completing its mission, the UAV returns to the recovering zone, and then was recovered by parachute under remote control.

在它的任務(wù)期間，WZ-5 UAV被它的運載飛機首先攜帶到目標地域，然后在4,000和5,000米高度釋放。UAV然后自動爬升到17,500米操作高度。一但進入目標地域，UAV飛行在自動駕駛儀控制下飛行，預(yù)-編程飛行參數(shù)，像是高度、路徑、速度、續(xù)飛時間和航程。在完成它的任務(wù)之后，UAV返回到回收區(qū)域，然后在遙控下采用降落傘回收。

The WZ-5 is fairly obsolete comparing to the modern Western-designed URAVs. It can only operate in day light period, and does not have the real-time datalink to transmit the imagery information to the ground. In addition, the WZ-5 can only fly according to the pre-programmed flight parameters, and cannot adjust its speed, altitude, and path according to the change of enemy air defence and weather. The ground control does not have any real-time control over the UAV.

WZ-5與現(xiàn)代西方設(shè)計的URAV相比是過時的。它只能在白天光照期操作，而且沒有實時數(shù)據(jù)鏈傳送圖像數(shù)據(jù)到地面。除此之外，WZ-5僅僅依照預(yù)-編程飛行參數(shù)飛行，而且不能夠依照敵人防空和天氣變化調(diào)整它速度、高度和路徑。地面控制不能實時控制空中的UAV。

The fuselage of the WZ-5 consists of six sections: the radar compartment, the camera compartment, the fuel tank, the engine compartment, the avionics compartment, and the parachute compartment. The UAV has five camera windows, and is fitted with day-light and infrared cameras for imagery intelligence (IMINT) missions. The aerial photos are stored on the films carried inside the UAV fuselage.

WZ-5的機身由六個部件所組成：雷達艙、照相機艙、燃料箱、發(fā)動機艙、航空電子艙和降落傘艙。UAV有五扇照相機窗口，而且配備有晝-光和紅外照相機用于圖像情報（IMINT）任務(wù)?？罩姓障鄡Υ嬖谀z片上在UAV機身內(nèi)攜帶。

The WZ-5 is powered by a WP-11 turbojet, rated at 8.33kN dry.

WZ-5由一臺WP-11型渦噴發(fā)動機提供動力，額定8.33kN凈推力。
