become equal to zero. The object will then fall at a constant velocity as described by Newton ’s first law of motion. The constant velocity is called the terminal velocity. What is aerodynamics? The word comes from two Greek words aerios concerning the air‚ and dynamis‚ meaning powerful. Aerodynamics is the study of forces and the resulting motion of objects through the

“The Evolution of Airplanes” Introduction This year is the 200th birthday of Charles Darwin (1809-1882)‚ the father of evolution. Darwin’s evolution theory proposes that all species of organisms‚ including human beings‚ evolved from common ancestors. There are five main characteristics in his evolution theory. First‚ there are variations among each population. Second‚ organisms compete for limited resources to exist. Third‚ traits of offspring are inherited from their parents. Forth‚ organisms

back to the bondages of terra firma? As a Commercial Pilot with over 800 hours‚ I am in constant awe of the fidelity of the principles and laws that allow me to escape the grips of gravity and observe the aerodynamics of flight. Although‚ there are many concepts when it comes to aerodynamics‚ I’m going to discuss the four major ones today. Lift‚ weight‚ thrust‚ and drag. During flight‚ there is a constant relationship between these forces. Lift is the upward force created by the effect of airflow

Part three Explaining how a thicker wing can be lighter than a thin wing when both are built for the same purpose: Firstly‚ the principle applying to the mass and thickness of wings applies to any aerofoil surface in any shape or form. How do we know a delta wing and a swept wing have heavier masses than a straight wing? Two important things need to come into account when measuring the thickness and weighing certain types of wings‚ the structural ‘Aspect Ratio’ and the ‘Thickness Ratio’ of aerofoil

manufactured during the 1990s) use a four-pole induction generator‚ which is directly connected to the grid and therefore runs at an almost constant speed: a little over 1500 rpm. A speed-increasing gearbox is used to couple the aerodynamic rotor to the generator. Thus‚ the aerodynamic rotor also runs at an almost constant speed‚ which leads to the term: fixed-speed wind turbine. A very similar arrangement could well be used in the conversion of a traditional windmill. A belt drive could be considered in

Introduction CAD (acronym for “Computer-Aided Design”) is one of the most popular software tools used all around the globe. CAD is a computerized platform for users to draw‚ modify and analyze designs‚ for example‚ CAD software such as AutoCAD‚ Solid Edge etc. Although what it basically capable of doing can be done by human hands‚ CAD is able to perform far more efficiently and accurately. Not to mention that for years‚ studies‚ researches and development are being carried out consistently to improve
