Aerodynamics is a branch of dynamics concerned with studying the motion of air‚ particularly when it interacts with a solid object. Aerodynamics is a subfield of fluid dynamics and gas dynamics‚ with much theory shared between them. Aerodynamics is often used synonymously with gas dynamics‚ with the difference being that gas dynamics applies to all gases. EARLY IDEAS Humans have been harnessing aerodynamic forces for thousands of years with sailboats and windmills.[1] Images and stories of flight

PROJECT BEng(Hons) Gaurab Ghosal ABSTRACT The wind tunnel being built in Scone airport is a closed loop wind tunnel. On completion this will provide a much needed facility for education purpose as it can be used by engineering students for aerodynamic evaluations. To conduct these evaluation proper evaluating tools needs to be setup. In this section the possible instruments that can be setup in this wind tunnel has been evaluated with Matlab based evaluation‚ AutoCAD drawings‚ morphological analysis

math involved. If you don’t use math and use it correctly then you will not win. Mathematics is involved in racing in two ways‚ the car setup and scoring an measurements. The car setup involves tire pressure‚ down force‚ wedge‚ aerodynamic Drag‚ camber‚ track bar and valance. The scoring system also uses math. In addition to scoring math is also used to measure different racing related subjects such as car weight‚ gas mileage time interval‚ qualifying‚ and the track characteristics

aircraft depends on every smallest possible detail of it. For designing a safer passenger aircraft a lot of investigation has to be done on flight failures‚ to prevent such failures. There are four main aspects considered while designing an aircraft: Aerodynamics‚ Propulsion‚ Structures and materials‚ Stability and control. An overview on the design of a fixed wing aircraft: The structure of an aircraft is configured as follows: A fuselage is a long cylindrical body with tapered ends to make its shape

a coastal launch site would probably be convenient as well. This aircraft design portion of the project is a very simplified version of the preliminary design process which will be undertaken by some of you in AE420. It requires only algebraic calculations. In several cases‚ rule-of-thumb estimations are used to avoid having to do analysis which is beyond the current technical background of the typical first year college student. These estimations are explained at the fundamental concept level when
