CASC Rainbow

CASC Rainbow (Cai Hong, abbreviated as CH) is the name of a series Chinese UAVs developed by China Academy of Aerospace Aerodynamics of China Aerospace Science and Technology Corporation (CASC), also known as the 11th Academy of CASC,[1] or 701st Research Institute.

CH-1

CH-1 is the first member of the Rainbow (CH) series UAV. The general designer was Mr. Shi Wen (石文), who is also the general designer of CH-2, the successor of CH-1, CASC PW-1, the derivative of CH-1, and CASC PW-2, the derivative of CH-2. CH-1 program first begun in 2000, and the success of CH-1 resulted in the establishment of UAV program which eventually led to other designs that followed. CH-1 is mainly intended for reconnaissance and surveillance missions.[2] Specification:[3]

CH-2

CH-2 is second member of Rainbow (CH) series UAV and it is a development of earlier CH-1, with identical twin-boom layout. As with its predecessor CH-1, propulsion of CH-2 is also provided by a two-blade propeller driven by a pusher engine mounted at the rear end of the fuselage, and the UAV is launched via vehicle mounted catapult with rocketed assisted take-off.[4][5] CH-2 is mainly intended for reconnaissance and surveillance missions.[2]

CH-3

CH-3 is a fixed wing UCAV of the Rainbow series. CH-3 adopts the unusual canard layout, similar to the Jetcruzer 450 and the Rutan VariEze. This means that the CH-3 lacks centrally located vertical tail, but has large winglets and canards. Propulsion is provided by a three-blade propeller driven by a pusher engine mounted on empennage. The main landing wheels of the tricycle landing gear has fairing to reduce drag.[6]

In January, 2015, a CH-3 drone was reported to have crashed in the north of Nigeria.[7] It is believed the drone was involved in Nigeria's struggle against the Islamic militant group, Boko Haram.[8] China supplied the CH-3 to Nigeria government prior to 2014, along with YC-200 guided bombs and AR-1 air-to-ground missile.[9]

Specification:[6]

CH-3A

CH-3A is the development of CH-3 and share the identical layout. Improvement of CH-3A over CH-3 includes that the maximum payload is increased to more than 100 kg, and satellite data link is also incorporated. CH3A is a multipurpose UAV which can also carry AR 1 laser guided rocket for attacking role. It is also widely rumoured that Myanmar Air Force operates them, and some images have been found, but there's no confirmation.Specification:[10]

CH-4

CH-4 is the largest fixed wing UCAV of the Rainbow series (as of end of 2013).[2] Externally, CH-4 looks almost identical to General Atomics MQ-9 Reaper, and the only distinct visual difference between two UAVs is that the ventral fin below the V-tail on MQ-9 is absent on CH-4.[11][12][13] There are two versions, the CH-4A and CH-4B. The CH-4A is a reconnaissance drone (capable of a 3500–5000 km range and a 30- to 40-hour endurance) while the CH-4B is a mixed attack and reconnaissance system with provisions for 6 weapons and a payload of up to 250 to 345 kg.

CH-4 is capable of firing air-to-ground missile from altitude of 5,000 meters, therefore the aircraft can stay outside of effective range of most anti-aircraft guns. It also allow CH-4 to be able to fire from a position that provides wider viewing area.[14]

Vasiliy Kashin, a China specialist at Moscow's Centre for Analysis of Strategies and Technologies, said that The CH-4B UCAV has been exported to Egypt, Saudi Arabia and Iraq.[15][16]

CH-5

Latest UCAV of the Rainbow series with a wingspan of 21 metres, a payload of 1,000 kg, a maximum takeoff weight of over 3 tons, a service ceiling of 9 km, an endurance of up to 120 hours[17] and a range of 10,000 km. Thanks to shared data link it can cooperate with CH-3 and CH-4 drones. It conducted its maiden flight in August 2015[18][19] and its first airshow flight (in northern Hebei province) in July 2017.[17] The drone can carry 16 missiles at a single time. There were also plans to extend its range up to 20,000 km.[20] Chinese officials claimed the CH-5 Rainbow was similar in performance to the US MQ-9 Reaper and "may come in at less than half the price." However, the maximum altitude of the CH-5 was 9 km compared to the 12–15 km of the Reaper and Chinese officials admitted the CH-5's engines were "weaker" than the Reaper's.[17]

CH-91

CH-91 is a fixed-wing UAV in twin-boom layout with inverted v-tail and a pair of skids as landing gear. Propulsion is provided by a two-blade propeller driven by a pusher engine mounted at the rear end of the fuselage.[21][22] CH-91 is mainly intended for reconnaissance and surveillance missions.[2] It's also called as BZK-008.

CH-92

CH-92 is a fixed-wing UAV in conventional layout with V-tail and tricycle landing gear. Propulsion is provided by a propeller driven by a pusher engine mounted at the empennage. CH-92 is mainly intended for reconnaissance and surveillance missions.[2][23]

CH-802

CH-802 is a fixed wing micro air vehicle (MAV) in conventional layout with elevated high-wing configuration and V-tail. CH-802 has a cylindrical fuselage and propulsion is provided by a two-blade propeller driven by a tractor brushless electric motor atop of the fuselage.[24][25] CH-803 is mainly intended for reconnaissance and surveillance missions.[2] CH-802 program begun in 2007 and was completed in 2008. Specification:[26][27]

CH-803

CH-803 is a fixed-wing UAV with a cylindrical fuselage and canards, but without tailplane. Propulsion is provided by two-blade propeller driven by a tractor engine mounted in the nose. Another unique feature of CH-803 is that it adopts forward-swept wing.[26] CH-803 is mainly intended for reconnaissance and surveillance missions.[2] CH-803 program begun in 2008 and was completed in 2011. Specification:[27]

CH-901

CH-901 is a fixed-wing UAV in conventional layout with cylindrical fuselage and high-wing configuration. Propulsion is provided by a two-blade propeller driven by a pusher engine mounted at the end of empennage.[28] CH-901 is designed as an UCAV.[2][29]
