Sinomux T280

The rotor downwash generated by the fuel-powered drone enhances crop penetration during pesticide spraying, improving pest control effectiveness. The Shitian SAS agricultural spraying system utilizes the engine's pulse principle and a patented catalyst to atomize the liquid into 20–50 microns, achieving eco-friendly mist spraying. This ensures even leaf coverage and reduces pesticide residue in soil. The engine TBO is 500 hours, offering high stability. The flight control system is developed in collaboration with top domestic and international manufacturers, using mature, customized, and modular control boards. The gearbox meets airworthiness standards, is structurally optimized using finite element analysis and bench life testing to achieve high torque, high power, and lightweight design. The aircraft offers high reliability and a service life of up to 30,000 hours. The rotor and flight platform adopt a multi-level protection architecture to enhance operational safety and extend overall lifespan.
