DT-500 tandem twin-rotor unmanned helicopter

The main advantage of the tandem twin-rotor configuration is the large longitudinal center of gravity range, so the fuselage has a large loading space, which has significant advantages especially in material delivery. Compared with helicopters of other configurations, there are usually strict requirements for cargo mounting. After changing the load or adjusting the mounting position, the heavy high-altitude crane needs to be re-trimmed. The center of gravity deviation is a very dangerous factor for conventional helicopters, which brings great trouble to users. The tandem-rotor configuration helicopter has a wide center of gravity range and is highly adaptable to changes in mounting position and load size. It does not require the user to accurately trim the center of gravity. It can save valuable time in emergency rescue, material delivery and other scenarios, and greatly improve the efficiency of the helicopter. Rescue efficiency.
