The DF-T2A is an octocopter designed for precision variable rate application of liquid pesticides, fertilizers, and herbicides, bringing new levels of efficiency and manageability to agriculture.
The DF-T2A‘s powerful propulsion system allows the aircraft to carry up to 10 kg liquid payloads, including pesticides and fertilizers.
The combination of speed and power means that an area of 4,000-6,000 m² can be covered in just 10 minutes, or 40 to 60 times faster than manual spraying operations. The intelligent spraying system automatically adjusts its spray according to the flying speed so that an even spray is always applied. This way, the amount of pesticide or fertilizer is precisely regulated to avoid pollution and economize operations.
Equipment used in plant protection operations is susceptible to dust and corrosion, leading to high maintenance costs and shortened lifespans. To counteract degradation, DF-T2A is designed with a sealed body and an efficient, integrated centrifugal cooling system. As it flies, the surrounding air enters the aircraft body via the front inlet, and a triple filter system keeps dust and debris from entering. The air then passes through each of the aircraft’s arms to the motors, capturing heat from all components and the entire structure before exiting and dissipating. The combination of cooling and filtering increases the expected lifespan of each motor by up to three times.
Spray nozzles can be chosen according to the properties of each liquid to optimize atomization, energy efficiency, and the amount of liquid sprayed. The included nozzles are resistant to wear and can be used for thousands of hours without degradation. In total, the DF-T2A has four nozzles, each placed directly below a motor. The downward airflow generated by the propellers accelerates the spray, increasing its reach.
The advanced flight controller integrated with the aircraft instantly and precisely responds to pilot inputs. Choose between three flight modes: Smart mode, Manual Plus mode and Manual mode, according to terrain and the specific requirements of each mission. In Smart mode, the flight can be easily planned with the press of a few buttons, without the need for mapping knowledge or other software, making the DF-T2A not only the most efficient but also the most easy to use spraying solution. In Manual Plus Mode, the aircraft performs the same turns at the press of a button as it does automatically under the Smart mode, allowing for planning to be done on the fly for fields of irregular shape. Under Manual mode, the pilot freely navigates the aircraft.
The DF-T2A automatically records its current coordinates and remembers its past coordinates as it makes its way across the field. In case an operation is interrupted, for example due to depleted battery or spraying liquid, users can quickly land and resume flight from the last recorded point after changing the battery or refilling its tank.
