The ZHZ TD220 is an Unmanned Helicopter System (UHS) developed by Zhong-Hang-Zhi (ZHZ) Science and Technology, Ltd of China. The type is an evolution of a series of drone helicopters that includes the earlier "TC" model. Both are of coaxial main blade rotor design, meaning a pair of main rotors are seated atop one another along a shared mast in the arrangement, offering notable stability and control. A key quality of the system is its Vertical Take-Off and Landing (VTOL) capabilities mimicking that of a conventional helicopter - this gives the UAS a considerably smaller footprint than a fixed-wing drone allowing it to operate where such types cannot.

The general layout of the aircraft is consistent with other market UHSs; the main rotors are fitted over the fuselage in the usual way and a four-point fixed skid assembly braces the body against the ground when landing/taking off. A pair of vertical fins are positioned at the tail for the needed control when airborne. An optics-laden traversable "blister" assembly is seated at the "chin" position of the aircraft allowing for unfettered views of the terrain ahead and below the aircraft. The conventionally-minded engine is buried within the design, driving power to the two main rotor blade assemblies seated in a coaxial arrangement.

The primary benefit of the stacked/twin main rotor units is the deleting of a tail rotor unit traditionally used to counter torque forces generated by a single mounting. When compared to leading coaxial blade developers, such as Russia's own Kamov design bureau, the ZHZ approach to its coaxial blade assembly is simplified by way of electrically-driven components (as opposed to mechanical), lowering costs while retaining all of the inherent benefits.

The TD220 sports a rotor diameter of 3.9 meters with a fuselage length of 2.48 meters and a total system height of 1.78 meters. Empty weight is 140 kilograms against an MTOW of nearly 300 kg. The helicopter can carry a payload up to 100 kg in weight up to an altitude of 4 kilometers and has a five-hour endurance window while cruising at speeds of 100 kmh. Power is supplied by a single gasoline- or kerosene-fueled engine of 65 horsepower.
