ASN-105多用途侦察无人机

D-4是西北工业大学研制的一种小型低空低速多用途无人驾驶飞机。可以执行航空摄影测绘、遥感探矿、人工影响天气和农田、森林病虫害防治和防火、灾情监视等。用于低空大比例尺航空摄影测量,特别适宜于在一些地域分散、面积较小的矿区、城镇、水库、河道、重点考古区、沙丘等进行大比例尺测图。飞行一个起落可拍摄30平方千米。军用编号ASN-105,主要作为靶机使用。

ASN-105侦察无人机系统是西安爱生技术集团公司在D-4基础上研制的侦察无人机系统。主要用于前线和敌后侦察,可完成战区实时监视、攻击前后战效分析任务。可提供实时无线电图象和硬拷贝图象,可装备夜视设备。系统包括六架无人机和一个地面站。ASN-105的遥控距离为100千米,机上装有全方位航向飞行控制系统、无线电系统、航空照相机及电视摄像机等,该机不需机场和跑道,借助火箭助推,在发射架上发射。

D-4无人机不需要机场和跑道。飞机借助于助飞火箭推力,在一轻便发射架上零长发射起飞。发射架固定在地上,也可安装在汽车或船舶的甲板上。飞机采用降落伞回收。整个发射起飞和开伞回收都是自动地按一定程序完成的。D-4于1980年3月开始研制,1982年10月首次试飞,1985年投入小批生产。

D-4是单发螺旋桨式上单翼小型无人驾驶飞机。飞机腹部装有双滑橇减震系统,以吸收着陆时的冲击。机内第二舱(容积0.34×0.33×0.35米3)、第六舱(容积0.30×0.34×0.35米3)、第八舱(容积0.24×0.24×0.24米3)可供装载专业设备。

设备和制导与控制 无线电设备由遥控分系统、遥测分系统、测向分系统和电视实时传输分系统组成。遥控分系统的功能是操纵无人机起飞与回收,操纵执行作业任务的航线,接收航迹控制系统的信号,实现自动遥控。遥测兼测距分系统的功能主要是测量无人机的空间座标和各种飞行数据。测向分系统的功能是指示无人机相对于基地的方位,配合测距系统组成单基地极座标(斜距R和方位角α)定位系统。

自动驾驶仪由垂直陀螺、高度传感器、磁感应器、运算放大器、伺服机构和时间程序装置等组成。可使飞机在无人操纵情况下稳定在某一种姿态飞行,通过遥控切换自动驾驶仪的状态,控制飞机等高定向直线飞行、等坡度左右盘旋或俯冲、爬高,组成需要的航线。

ASN-105多用途侦察无人机 :: 空军世界

The ASN-104 and ASN-105 UAV were developed in the 1980s by Xi'an ASN Technology Group Company, and was revealed by China Aviation Technology Import and Export Co. (CATIC) in the 1990s for export market. Both of these UAVs are also in service with the PLA for tactical reconnaissance, day/night surveillance, border patrol, artillery spotting, and aerial photography and prospecting.

Both UAVs are capable of transmitting imagery data to the ground station in real-time. The ASN-104 has a maximum remote-control distance of 60km, while the ASN-105’s maximum remote-control distance is 100km. The ASN-104 made its maiden flight in February 1982, and received its design certificate in December 1983. The ASN-105 first flew in the mid-1980s.

DESIGN FEATURES

Each system has six UAVs and the ground station, which comprises 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, and recovered by parachute. The UAV is fitted with an under-fuselage impact absorbing device to minimise the damage caused during recovering.

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.

MISSION PAYLOAD

The basic variant of the UAV is fitted with an aerial photographic camera and a television imaging system. 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.

GROUND STATION

The ground station of the ASN-104 include 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.

The ASN-105 has an integrated radio tracking/remote-controlling system which can perform the tracking and controlling of the UAVs. The system is fully computerised. The UAV can fly according to the pre-programmed autopilot, and can be switched into remote-controlling mode at any stage of the flight. The system can be assisted by a tripod-mounted signal relay system, which can be carried by crewmembers in the mountain regions to receive and re-send the image signals.
