Abstract:

For effectively extinguishing forest fire, and protecting the safety of firefighters, a kind of forest fire extinguishing bomb which can strike precisely was designed based on Beidou navigation system, and the core technologies were studied. The study background and realistic meaning were elaborated, and the necessity of the study was verified. The structure of the fire extinguishing bomb was designed and analyzed, and the internal structure was introduced in detail. The overall parameters and characteristic parameters of the flying track were measured.Combined with the chart, focused on analyzing the navigation module-ATK-S1216F8-BD GPS-BD module, and the key to this design basis: Beidou navigation system. The selection of filling agent and the usage process of the forest fire bomb and technology advantages were introduced briefly. By calculation, the projectile can reach 12.4 km, and the coverage area can be 400 km2, carrying 400 kg of fire extinguishing agent. The related basic technical indexes meet the design expectations.
