Engineering:FYAT Multirotor

FYAT multirotors are Chinese UAVs developed by Linyi Feng-Yun (meaning Wind Cloud) Aviation Technology Co., Ltd. (FYAT, 临沂风云航空科技有限公司), some of which have entered service with Chinese law enforcement and other governmental establishments.

Dodecacopter

Dodecacopter is a dodecarotor designed by FYAT, with a total of twelve rotors. Dodecacopter is similar to another multirotor developed by FYAT, the FYAT Intelligent Eagle. Common feature shared by both multirotor is that the fuselage is l shaped, with a total of six arms attached, three on each side. Each arm has a pair of two-blade rotors attached to its end, one above the other. Dodecacopter differs from Intelligent Eagle in the arrangement of the last pair of arms. For Intelligent Eagle, all arms are arranged in almost equal distance, the angles formed between the first pair of arms with the central pair is almost equal to the angle formed between the last pair of arms with the central pair. However, for dodecacopter, the angle formed between the last pair of arms and the central pair of arms is much larger than the angle formed between the first pair of arms and the central pair of arms, so the last pair of arms of dodecacopter are much closer to each other.

Experimental Quadcopter

Experimental Quadcopter (Si-Xuan-Yi Shi-Yan-Ji, 四旋翼实验机) is an experimental UAV developed by FYAT, and it is used to test the feasibility of some design features. One of such feature is the center to which all four arms attached to. Instead of the usual circular shape adopted by most quadmotors in the world, the center of this experimental quadcopter is rather unconventional in that the center is shaped like a rectangle at one end, combined with a semi-circle shape at the other end. Experimental Quadcopter is used to test the weight distribution and aerodynamics of this unconventional design of the center. Another concept tested by the Experimental Quadcopter is that each rotor is attached to the rotor next to it by an arm, forming a shape of square enclosing an X, instead of the usual X-shape of most quadcopter. Both design concepts proved to be successful and have seen been since adopted by other quadcopters designed by FYAT.

FHP-Z1622 is a derivative of FHP-Z615/Z617 series.

H8

H8 is an octocopter is a multirotor developed by FYAT, and the landing gear consists of a pair of skids. H8 has a very unusual shape than typical octocopter: instead of having eight arms attached to the center, H8 only has two arms attached to center in paralled, forming a shape of H. On each arm, there are four three-blade rotors mounted.

Intelligent Eagle

Intelligent Eagle (Zhi-Hui-Ying or Zhihuiying, 智慧鹰) is a dodecacopter developed by FYAT, with very unusual look that distinguish it from most of Chinese multimotors. The landing gear consists of four legs each with a wheel attached. The fuselage is l shaped, with a total of six arms attached, three on each side. Each arm has a pair of two-blade rotors attached to its end, one above the other.

Magic Talon Quadcopter

Magic Talon (Mo-Zhua or Mozhua, 魔爪) Quadcopter is quadrotor developed by FYAT, and the landing gear consists of a pair of skids. Magic Talon Quadcopter is constructed of carbon fiber composite material and it incorporates modular design concept, which enables different subsystems to be adopted according to the customers’ specific requests.

Magic Talon ZC001

Magic Talon ZC001 is another member of multirotors developed by FYAT. The most obvious external difference between Magic Talon ZC001 and the other two member of Magic Talon multirotors is that Magic Talon ZC001 lacks the pair of skid as its landing gear.

Micro Quadcopter

Micro Quadcopter is a quadrotor developed by FYAT, and the landing gear consists of a pair of skids. Micro Quadcopter is designed to have a relatively longer endurance in comparison to other multirotors of the same class, up to half an hour. The electrically powered quadcopter has some unusual design features in that instead of the usual two-blade rotors adopted by most quadcopters in the world, Micro Quadcopter incorporates four three-blade rotors instead. Another unique feature of Micro Quadcopter is that each rotor is also attached to each other in addition to being attached to the center: each rotor is attached to the rotor next to it by an arm, forming a shape of square enclosing an X, instead of the usual X-shape of most quadcopter. This design was first tested on the FYAT Experimental Quadcopter mentioned above, which proved to be successful and subsequently adopted by Micro Quadcopter.

Octadecacopter

Octadecacopter is a multirotor with eighteen rotors developed by FYAT. There are six Y-shaped arms each with three two-blade rotors, two of which are located at the tip of the Y, and the third rotor is mounted at the middle of the leg of the Y, which is attached to the center of the UAV. The landing gear consists of two pairs of skids, each perpendicular to the other, as opposed to a single pair of skids adopted by most UAVs. The branches of Y-shaped arm can be folded to save space.

Pathfinder

Pathfinder is a quadrotor developed by FYAT powered by four two-blade rotors, and the landing gear consists of a pair of skids. The center to which all four arms are attached to is not the usual circular shape as in most quadcopters, but instead, it is shaped like a rectangle at one end, combined with a semi-circle shape at the other end. This design was first tested on the FYAT Experimental Quadcopter mentioned above, which proved to be successful and subsequently adopted by Pathfinder.

Quadcopter

Quadcopter is another quadrotor developed by FYAT, and the landing gear is consisited of a pair of skids. What’s rather unusual about this quadcopter and other Chinese quadcopter is that all four arms are attached to each other also, in addition to being attached to the center. The four rotors are jointed together with an arm forming a circle. Specification:

• Endurance (min): 30

Shield

Shield (Dun-Pai or Dunpai, 盾牌) is a hexacopter developed by FYAT, and the landing gear consists of a pair of skids. Shield hexacopter incorporates modular design concept to enable different rotors to be rapidly changed to meet different mission requirements. Shield hexacopter has been adopted by Chinese police.
