Compared with fixed wing aircraft, helicopters have many unique advantages, such as vertical takeoff and landing, hovering in the air, and flexible steering. Unmanned helicopters also inherit the above advantages. However, due to differences in the functional positioning and manufacturing level of unmanned helicopters in various countries, these unmanned helicopters usually have some "personality". Last year, the UAE Ministry of Defense signed a contract with EDGE Group to purchase 200 unmanned helicopters, including the HT-100 unmanned helicopter on the purchase list. The positioning of HT-100 unmanned helicopter was originally for civilian use. Its "size" is not large, the rotor is relatively long, and the shell and other parts are made of lightweight carbon fiber and other composite materials, and it also uses fuel driven mode. This design allows it to carry heavier loads with a compact body. To ensure safe and reliable flight, it can choose different types of fuel and use electric drive to provide backup. When it loses power, it can land autonomously with the help of a parachute. In addition to the above advantages, it also has other capabilities, such as the ability for users to manipulate it within a distance of 200 kilometers through encrypted data links. Modular design and scalable software upgrade capabilities enable it to carry corresponding modules for tasks such as intelligence reconnaissance and surveillance, fire guidance, etc. Therefore, the HT-100 unmanned helicopter has also been purchased and installed in the military by some countries.
