  7. Abstract:
  8. In this research work, the concept of an unmanned aerial firefighting system with water thrusters has been studied. This system consists of a platform head, a waterhose and a ground pump. The concept is briefly to pump water through the hose and then fall it down on fire from the platform. This conceptual system may have many other applications. The other applications have also been addressed in the introduction section. This platform can be considered as an unmanned aerial vehicle whose lift and control forces is provided by water thrusters. The conceptual study has been carried out based on three subjects of preliminary sizing, system dynamic modeling and controller design for platform stability. To stabilize the platform, two feedback linearization and sliding mode controllers have been designed, which operate in the form of a cascade structure. This control system is able to keep the platform almost horizontal to the ground against external disturbances. Besides, a computer program has been written to simulate the movement of the system and show the outputs in the form of an animation. The program has been used in validating the model and investigation of the performance of the controllers. Finally, different features of the system dynamics has been discussed briefly
