The appearance of the "Black Hornet 4" drone has attracted attention from Cao Yabo and Zhang Qiyuan. According to the Defense News website in the United States, at a recent meeting of the US Army Association, Phillip Defense Company launched the "Black Hornet 4" unmanned reconnaissance system for individual soldiers. As a new generation of micro nano drones, the appearance of the "Black Hornet 4" drone has attracted external attention. The advanced performance "Black Hornet 4" drone follows the basic architecture of the "Black Hornet" drone family with rotor and tail wings, resembling a pocket helicopter in appearance. The drone can fly continuously for over 30 minutes, with a range of about 2 kilometers, and its body can withstand interference from 25 knots of wind speed. At the same time, on the basis of inheriting the universal advantages of the "Black Hornet" family of drones, the aircraft's various performance has been further enhanced. Small and portable. The 'Black Hornet 4' drone is small in size and weighs about 70 grams, and can be carried in a pocket. This machine is mainly used for obtaining and transmitting intelligence, without storage function, so it is not equipped with storage payload, further reducing the weight of the body. The 'Black Hornet 4' drone is powered by electricity and has outstanding silent performance, making it easy to perform covert tasks. High definition night vision. The 'Black Hornet 4' drone is equipped with two 12 megapixel daytime cameras and one high-resolution thermal imager. Daytime cameras have low light performance and can serve as an effective supplement to high-resolution imagers in dark environments. During night operation, the drone can fuse information from the camera and thermal imager, automatically generating clear and reliable images, enabling operators to identify potential threats or other interested targets. Accurate intelligence. The 'Black Hornet 4' drone is equipped with advanced sensor systems and has excellent autonomous flight capabilities. At the same time, the machine can autonomously identify obstacles and move quickly according to task requirements. In addition, the intelligent system of the drone has strong computing power and can independently analyze complex intelligence information, determine its own position indoors without control signals, and conduct autonomous reconnaissance. Instant messaging. The 'Black Hornet 4' drone can communicate wirelessly with command centers or other drones, and has encryption transmission and anti-interference capabilities. Multiple 'Black Hornet 4' drones can collaborate to complete complex tasks such as search, reconnaissance, guidance, and strike. Since its inception, the versatile "Black Hornet" drone has been purchased and installed in over 40 countries, and has been put into use in some local wars and urban rescue operations. From the actual combat situation, this type of drone mainly plays the following roles on the battlefield. The 'sharp weapon' of street warfare. The operational advantage of the Black Hornet 4 drone in urban environments is evident. With its compact and flexible body and strong night vision ability, this type of drone can not only freely shuttle through densely populated cities, but also enter buildings or dark pipelines for all-round reconnaissance, ensuring that its own troops do not fall into a tight encirclement. Spy "assistant". The 'Black Hornet 4' drone is compact in size and can take off and land on the palm of the hand, completing launch within 20 seconds. It can perform tasks autonomously without GPS signal. Thanks to the support of these advanced performances, this UAV can be used to
