Aerodynamic Modeling of UAV Project for the Peruvian Air Force

The development of UAV systems over the past three decades has been consistent and considerably helpful in many areas such asmilitary Intel operations, surveillance, scientific research, mining, industrial fishing, agricultural Industry, etc. Both military and the civilian world have benefited from the multiple uses a UAV systemcan be given. The Peruvian Government realized the necessity of developing its own UAV system, reason why the Center of Development of Projects (CEDEP) of the Peruvian Air Force (FAP) is developing thefirst Peruvian UAV system, with the support of the National Council of Science, Technology, and Technological Innovation (CONCYTEC). This paper summarizes the aerodynamic modeling of the firstprototype of the project.
The aerodynamic modeling of the prototype went through the following phases: Conceptual Design and sketch of the design, 2-D Airfoil and Finite Wing Analysis, Design Analysis,and flight test of the first prototype based on the final design.
The conceptual design was based on the requirements for the prototype. The prototype will be a medium range, long endurancesurveillance UAV for both military and civilian purposes. Following this line, the prototype has a conventional design for a long endurance aircraft, with a propeller pusher piston engine. The prototype iscapable of carrying a specified payload, and will be an autonomous aircraft managed from a ground station. The autopilot uses GPS technology.

The Design Airfoil softwarewas used to perform the 2-D Airfoil and Finite Wing Analysis. The software allows you to explore any kind of four, five and six digit NACA airfoils by giving you its corresponding aerodynamiccoefficients. A NACA Airfoil was chosen for the prototype’s wing as it was best suited to accomplish the mission requirements. The Wing Span (b) and consequently wing size area (S) were chosen by our...
