海洋强国路超话【AR-500B舰载型无人直升机成功首飞】11月27日,航空工业研制的AR-500B舰载型无人直升机在鄱阳试飞基地首飞成功,该型号的成功研制填补了我国轻小型舰载无人直升机领域的空白。AR-500B舰载型无人直升机最大起飞重量500kg,任务载荷 70kg,最大续航时间4h;控制半径100km,最大平飞速度140km/h,巡航速度120km/h,使用升限4000m,可以广泛用于执行海面广域监视与识别任务。
为适应舰载无人直升机停放空间小、工作环境恶劣、起降过程风险大、电磁环境复杂等不利因素,直升机所设计团队在原型机的基础上换装重油发动机,对燃油、结构、电气、飞控系统进行适应性改装设计。
针对无人直升机的海上使用需求,直升机所设计团队开展了小型电动助降装置、着舰引导系统和自动着舰控制律等设计研制;针对海上使用环境,开展了“三防”(防湿热、防霉菌、防盐雾)环境试验,使AR-500B舰载型无人直升机能够基本适应海上及船上环境。

[AR-500B ship-based unmanned helicopter successfully made its first flight]
On November 27, the AR-500B carrier-based unmanned helicopter developed by the AVIC successfully flew for the first time at the Poyang test flight base. The successful development of this model has filled the gap in the field of light and small ship-borne unmanned helicopters in China. AR-500B ship-based unmanned helicopter has a maximum take-off weight of 500kg, a mission load of 70kg, and a maximum endurance of 4h; a control radius of 100km, a maximum level flight speed of 140km/h, a cruising speed of 120km/h, and a service ceiling of 4000m. It can be widely used to perform wide-area surveillance and identification tasks at sea.
In order to adapt to difficult factors such as small parking space of the shipborne and harsh working environment, the high risk of take-off and landing, and the complicated electromagnetic environment, the helicopter design team replaced the original prototype with heavy oil engine and design adaptive modification on the fuel, structure, electrical and flight control system.
In response to the needs of unmanned helicopters at sea, the design team of the Helicopter Institute has carried out the design and development of small electrical landing assistance devices, landing guidance systems and control rules for automatic landing. Specifically against the maritime environment, the "Three Preventions" (anti-humidity, anti-mold, anti-salt spray) environmental test has been carried out, such that the AR-500B ship-based unmanned helicopter could basically adapt to the marine and shipborne environment.
