Numerical modelling of the aerial drop of firefighting agents by fixed-wing aircraft – Part I: Model development Article in International Journal of Wildland Fire 20(3)– January Numerical studies of the deposition of material released from fixed and rotary wing aircraft / (Washington, D.C.: National Aeronautics and Space Administration, Scientific and Technical Information Office ; [Springfield, Va. The AGDISP software is a computer code that predicts, as a function of time, the path of material released from a helicopter or fixed-wing aircraft, and deposited on the ground or in a canopy. Thus, there is a need for a flexible vehicle sizing, trade-off, and optimization capability that is not limited to a single vehicle configuration (e.g., fixed-wing, rotary-wing) or propulsion.

A limitation of a fixed-wing aircraft is the need for a designated landing area, which may not always be close to the application site. Rotary-wing aircraft used for pesticide application are more maneuverable but slower than fixed-wing aircraft, and can operate over a range of speeds and in almost any area since they do. First manually controlled, fixed wing, motorized aircraft flies at Kitty Hawk, North Carolina by Orville and Wilbur Wright. See Claims to the first powered flight. The Fleming valve, the first vacuum tube and diode, is invented by John Ambrose Fleming. The first free flight of a rotary-wing aircraft is carried out by Paul Cornu.

Perhaps two of the most well-known fixed-wing projects of the past are the Smart Wing program and the Smart Aircraft and Marine Propulsion System demonstration (SAMPSON) [18, 19]. The Smart Wing program was intended to develop and demonstrate the use of active materials, including SMAs, to optimize the performance of lifting bodies [20–23]. The computer code AGDISP (AGricultural DISPersal) has been developed to predict the deposition of material released from fixed and rotary wing aircraft in a single-pass, computationally efficient manner. The formulation of the code is novel in that the mean particle trajectory and the variance about the mean resulting from turbulent fluid.
