CDADI UAVs are Chinese experimental UAVs developed by Chengdu Aircraft Design Institute (CDADI), also known as the 611th (Research) Institute (611所), some of which has developed into production models and entered service with various Chinese governmental establishments.

CADI-3

CADI-3 is a very little known Chinese UAV developed by CDADI which can change its shape during flight, and its existence was revealed in September 2011 when it entered AVIC Cup as one of the contenders.

Coaxial Shape Varying Rotary Wing UAV

Coaxial Shape Varying Rotary Wing UAV (Gong-Zhou Bian-Ti Xuan-Yi Wu-Ren-Ji, 共轴变体旋翼无人机) is an artillery launched UAV developed by CDADI, and the general designer is Mr. Jin Xi (金曦) of the 10th Department of CDADI. Coaxial Shape-Varying Rotary Wing UAV is also known as Artillery-Launched Shape Varying Unmanned Reconnaissance System (Pao-She Bian-Ti Wu-Ren Zhen-Cha Xi-Tong, 炮射变体旋翼无人侦察系统), because it was originally intended for reconnaissance missions when it made its public debut in October 2012 at the 5th Chinese Innovation Cup future aircraft design competition held in Beijing. Unlike most entries of the competition, most of which are merely proposals or futuristic dreams, Artillery-Launched Shape Varying Unmanned Reconnaissance System is one of the few entries at the competition that are actually practical enough to be built in the present, and since then, several prototypes have been completed. The function of the UAV subsequently expanded, including as a cruise missile, and the name has since changed to Coaxial Shape Varying Rotary Wing UAV accordingly.

Coaxial Shape Varying Rotary Wing UAV is designed to be deployed by rocket artillery, and once launched, the UAV can be either used as a reconnaissance platform, or a cruise missile to attack selected targets. Coaxial Shape Varying Rotary Wing UAV shapes like a rocket artillery round, and propulsion is provided by a three-blade propeller driven tractor engine mounted in the nose. A cruciform tail consisting four cropped delta wings mounted at the empennage, and an additional pair of main wing is mounted in the midsection, closer to the tail. A little further from the main wing toward the nose, there is a pair of much smaller swept wing mounted perpendicular to the main wing. Wings and propellers are deployed after the rocket booster is jettisoned in flight after launch, Specification:

• Length (m): 1.5 m
• Range (km): 350

Mad Warrior

Mad Warrior (Kuan-Zhan-Shi, 狂战士) UAV is an experimental UAV that changes the shape of its wing at different speed for better performance. However, unlike typical variable-sweep wing aircraft which sweeps at different angles at different speed, the outer portion of the main wing of the Mad Worrior at supersonic speed folds upward to a ninety degree position perpendicular to the inner portion of the main wing. Externally, Mad Warrior UAV visually resembles McDonnell Douglas X-36, with some minor difference. One of such difference is that the canards of Mad Warrior are swept wings instead of delta wings used on X-36, but the canards of Mad Warrior UAV would be completely retracted into the fuselage at supersonic speed to reduce drag. At subsonic speed, the canards of Mad Warrior are fully extended and the out portion of the main wing would not be folded. Mad Warrior is powered by a turbofan with inlet located atop of the fuselage to increase stealth. The existence of Mad Warrior was revealed in 2011 when it entered AVIC Cup competition as one of the contenders.

Rotary Dragon

Rotary Dragon (Xuan-Long or Xuanlong, 旋龙) is a fixed wing experimental UAV with tricycle landing gear developed by CDADI to explore the application of engine tilting technology on aircraft. Rotary Dragon has a very flat fuselage, which is as thin as its wing. Propulsion is provided by a jet engine mounted atop of the fuselage in a rectangular engine compartment, and twin tail are installed at the rear end of the engine compartment. The engine compartment is capable of rotating 360° in flight, so that the entire UAV can go forward, backward, port, starboard or any other direction at level flight without pointing the nose to the direction. The complete name is Rotary Dragon Longitudinal and Latitudinal Flight Aspect Changing Aircraft (Xuan-Long Zong-Heng Fei Bian-Xiang Fei-Xing-Qi, 旋龙纵横飞变向飞行器).

Leap Dragon

Leap Dragon (Yue-Long or Yuelong, 跃龙) is a fixed wing experimental UAV with tricycle landing gear developed by CDADI. Leap Dragon has a tandem wing layout with two piston engines. .

Sea Patroller

Sea Patroller (Hai-Xun-Zhe or Haixunzhe, 海巡者) UAV is a fixed wing UAV is twin boom layout, and proplusion is provided by a two-blade propeller driven pusher engine mounted at the rearend of the fuselage. Sea Patroller is specifically designed for ocean surveillance missions and thus carries a various electro-optical equipment for such mission. Sea Patroller is launched by catapult. Specification:

• Endurance (hr): 4, 6 or 8
• Range (km): 200
• Launch: catapult
