Yintong UAV

Yintong UAVs are Chinese UAVs developed by Zhuhai Zhuhai Yintong (meaning Silver Through) Aviation Supplies Co. Ltd. (珠海银通航空器材有限公司) of Yintong Group (Yintong, 银通集团). Although the manufacturer advertised the military potential of their products, most of the products are deployed in agricultural applications.

Grand Marshal

Grand Marshal (Da-Shuai, or Dashuai, 大帅) is an unmanned coaxial helicopter with land skids, and it is designed for various missions including military and law enforcement, but it is not clear if it has entered service with Chinese military or law enforcement because no such information has been publicized yet.[1] Specification:[2]

Length: 3.6 m
Main rotor diameter:4 m
Height: 1.8 m
Endurance: 2 hr
Weight: 70 kg
Payload: 50 kg
Fuel: 20 L
Engine: 35 hp

Vanguard 260

Vanguard (Xian-Feng or Xianfeng, 先锋) 260 is an unmanned helicopter specifically designed for agricultural missions such as crop dusting. Vanguard 260 utilizes commercial off-the-shelf (COTS) subsystems, such as the widely used 260 series airframe, which it derives its name from. Vanguard 260 is in conventional layout with landing gear consists of a pair of skids, and the unit price is ¥ 160,000. The advantage of using Vanguard 260 is that in comparison to traditional manual spraying, water used is greatly reduced to less than a kilogram per decare and can spray more than one decare per minute. [3]

YT-P5

YT-P5 is an unmanned helicopter that is specifically designed for aerial survey, aerial photography and aerial surveillance missions. YT-P5 is powered electrically by another major product of Yingtong, the lithium battery. YT-P5 has conventional helicopter layout.[4] Specification:[5]

Main rotor diameter: 1.82 m
Tail rotor diameter: 0.3 m
Full length: 2.175 m

Empty weight: 8.5 kg (including batteries)
Takeoff weight: 11 kg
Cruise speed: 52 km/hr
Endurance: 25 min
Ceiling: 1 km
Remote control radius: 5 km

YTF-DL-I

YTF-DL-I is a derivative of YT-P5, and it is specifically designed for aerial overhead power line inspection. The characteristics of YTF-DL-I is identical to that of TY-P5, and the only external visual difference between the two UAVs is that YTF-DL-1 has an additional fairing added in the nose for better aerodynamic flows. DL = Dian Li (电力, meaning power source in Chinese)[6]

YTF-JY-I

YTF-JY-I is a derivative of YT-P5 and it is specifically designed for police missions. The difference between YTF-JY-I and YTF-DL-1 is that the fairing in the nose of YTF-JY-1 can be rapidly removed in the field to meet different requirement of the equipment to be carried. For example, fairing could not be present if the payload is a loud speaker for broadcasting messages. JY = Jing Yong (警用, meaning police applications in Chinese).[7]

YTF-XF-I

YTF-XF-I is YTF-JY-I is a derivative of YT-P5 and it is specifically designed for fire fighting applications. As with YTF-JY-1 and YTF-DL-I, the other two derivatives of YT-P5, the publicized characteristics of YTF-XF-I is identical to that YT-P5. XF = Xiao Fang (消防, meaning fire fighting in Chinese)[8]

YT-A5

YT-A5 is an electrically powered unmanned helicopter that is designed for agricultural applications such as crop dusting, with A stands for Agriculture. YT-A5 is able to carry 5 liters of liquid chemicals such as pesticide or fertilizer. Specification:[9]

Main rotor diameter: 1.82 m
Tail rotor diameter: 0.3 m
Full length: 2.175 m
Fuselage length: 1.52 m
Width: 0.58 m
Height: 0.71 m
Empty weight: 9 kg (excluding chemical carried)
Takeoff weight: 14 – 15 kg

YT-A10

YT-A10 is an electrically powered unmanned helicopter that is designed for agricultural applications such as crop dusting, with A stands for Agriculture. YT-A5 is able to carry 10 liters of liquid chemicals such as pesticide or fertilizer. Specification:[10]

Main rotor diameter: 2.1 m
Tail rotor diameter: 0.3 m
Full length: 2.175 m
Fuselage length: 1.9 m
Width: 0.86 m
Height: 0.6 m
Empty weight: 10 kg (excluding chemical carried)
Takeoff weight: 20 kg

Yintong 1

Yintong 1 (银通一号) is a development of YT-P5 with slight variation is characteristics and fairing added. Performance is also improved. Specification:[11]

Main rotor diameter: 1.82 m
Tail rotor diameter: 0.32 m
Full length: 2.17 m
Fuselage length: 1.56 m
Width: 0.34 m
Height: 0.6 m
Empty weight: 5.5 kg (including batteries)
Payload: 5 kg
Cruise speed: 100 km/hr
Endurance: up to 30 min
Ceiling: 4 km
