Abstract: -Wind tunnel testing has long been an important component common to many introductory fluid mechanics and aerodynamics courses. wind tunnel was designed and fabricated to reduce the drag and lift forces. A wind tunnel consists of a tubular passage with the object under test mounted in the middle. Air is made to move past the object by a powerful fan system or other means. The test object, often called a wind tunnel model, is instrumented with suitable sensors to measure aerodynamic forces, pressure distribution, or other aerodynamic-related characteristics. The main work of the wind tunnel is to improve the design according to the aerodynamic shapes. It was observed that velocity is increases and pressure is decreases on the solid object with gradually increasing height up-to maximum height along the length. Understanding physical characteristics is very important to automotive aerodynamic design, for maximizing fuel economy, and in the teaching of basic principles of aerodynamic design as applied to aircraft.Keywords: - Aerodynamics, fabrication, design, drag and lift.
