ASN-104型(D-4)無人機(jī)(中國(guó)英特網(wǎng))
The ASN-104 (also known as D-4) tactical unmanned reconnaissance aerial vehicle (URAV) was developed by Xi'an ASN Technology Group Company, a commercial company of the Northwest Polytechnic University (NPU) in early 1980s. The ASN-105 is an improved variant introduced in the early 1990s. The ASN-104/105 was the first generation indigenous tactical URAV in service with the PLA, designed for battlefield reconnaissance, day/night surveillance, border patrol, artillery spotting, and aerial photography and prospecting roles.
ASN-104型(也即是D-4型)戰(zhàn)術(shù)無人偵察機(jī)(URAV)由西安愛生技術(shù)集團(tuán)公司發(fā)展,1980年早期西北理工大學(xué)(NPU)成立的一家商業(yè)公司。ASN-105型是一種在1990年早期推出的改進(jìn)型。ASN-104/105型是在PLA服役的第一代國(guó)產(chǎn)戰(zhàn)術(shù)無人偵察機(jī)(URAV),設(shè)計(jì)用于戰(zhàn)場(chǎng)偵察、晝/夜監(jiān)視、邊境巡邏、火炮(落彈)觀測(cè)、航空攝影和探礦任務(wù)。
Programme
NPU began to develop a lightweight tactical battlefield surveillance uav in the early 1980s. The resulted D-4 (ASN-104) made its first flight in October 1983 and entered batch production in 1985. The D-4 was designed for military reconnaissance and civil aerial photographic survey. The onboard optical and night vision cameras can provide real-time TV images of the battlefield within 60km range. The ASN-105 was developed in the mid-1980s based on the ASN-104, but with an extended range of 100km and an improved ground control system.
計(jì)劃
NPU在1980年早期開始發(fā)展一種輕型戰(zhàn)術(shù)戰(zhàn)場(chǎng)監(jiān)視UAV。D-4(ASN-104型)在1983年10月作了它的首次飛行并在1985年進(jìn)入了批量制造。D-4被設(shè)計(jì)用于軍事偵察和民用航空照相測(cè)量。機(jī)載光學(xué)和夜視攝像機(jī)能在60公里范圍內(nèi)提供戰(zhàn)場(chǎng)實(shí)時(shí)電視圖像。ASN-105型基于ASN-104型在1980年中期發(fā)展,但是具有100公里的更大范圍和一套改良地面控制系統(tǒng)。
Design
The ASN-104 has high-mounted wings, slightly tapered from roots to tips. The ASN-105’s wings are high-mounted, straight to the midsection, and tapered from mid-wing to tips. The engine is a single, prop-driven engine in the nose section. The fuselage is round and tapers to front and rear, with fixed landing pads. The tail flats are high-mounted on the body and equally tapered. The fin is equally tapered.
設(shè)計(jì)
ASN-104型采用高翼位,從翼根到翼尖輕微漸縮。ASN-105型高翼位,從翼根筆直到中部并從中部到翼尖漸縮。單發(fā)動(dòng)機(jī),螺旋槳驅(qū)動(dòng)發(fā)動(dòng)機(jī)在機(jī)頭部位。圓形機(jī)身和從頭到尾漸細(xì),采用固定登陸橇。高翼位尾平翼安裝在機(jī)身上并呈梯形,尾直翼也呈梯形。
The ASN-104/105 is powered by a HS-510 four cylinder dual ignition air cooled piston engine with a power rating of 22kw. The engine uses ordinary automobile fuel.
ASN-104/105型動(dòng)力由一臺(tái)HS-510型四缸雙活塞氣冷活塞發(fā)動(dòng)機(jī)提供具有22千瓦功率,發(fā)動(dòng)機(jī)使用普通汽車燃料。
A complete UAV system comprises six UAVs and a ground control station. The ground control station consists of a command & control vehicle, a mobile control vehicle, a mobile photo processing vehicle, and a mobile television image processing vehicle. The UAV is launched by rocket boosters from a mobile launcher, and recovered by parachute. The UAV is fitted with an under-fuselage impact absorbing device to minimise the damage caused during recovering.
一套完整UAV系統(tǒng)包括六架UAV和一套地面控制站。地面控制站由一輛指揮&控制車、一輛機(jī)動(dòng)控制車、一輛機(jī)動(dòng)相片處理車和一輛機(jī)動(dòng)電視圖像處理車組成。UAV采用火箭助推器從一個(gè)機(jī)動(dòng)發(fā)射架發(fā)射,并被降落傘回收。UAV安裝使用一種機(jī)身下減震裝置去把回收期間產(chǎn)生的損害減到最低。
The UAV is fitted with an aerial photographic camera and a television imaging system with night vision channel. The imagery intelligence can be transmitted to the ground station in real-time, or stored in data storage devices. In a typical mission, the photographic camera can cover an area of up to 1,700 square kilometres. The size of the photo is 18cm X 18cm. Later variants could carry night vision devices and CCD cameras.
UAV配備有一臺(tái)航空照相機(jī)和一套電視圖像系統(tǒng)。圖像情報(bào)能被實(shí)時(shí)傳送到地面站或儲(chǔ)存在數(shù)據(jù)存儲(chǔ)裝置中。在一個(gè)典型任務(wù)中,照相機(jī)能覆蓋1,700平方公里區(qū)域。相片大小18厘米X18厘米。稍后改型可以攜帶夜視型器件和CCD照相機(jī)。
Ground Station
The ground station of the ASN-104 includes the radio tracking system, radio remote-control system, radio positioning and television image processing equipment. Each control station has two crewmembers: a navigator/commander and a UAV controller. If necessary, the radio tracking and remote-controlling systems can be disintegrated from the command and control vehicle and become man-portable. The aerial photographic photos and television images are processed in the mobile photo processing vehicle (dark room) and the mobile television image processing vehicle respectively.
