designed completely different than one built for speeds above Mach 1 due to significant changes in force load and the creation of supersonic shockwaves. However the way an aircraft is constructed is just as important as its design in the overall aerodynamics and structural integrity of the craft. Modern aircraft are constructed with thin sheets of a low weight‚ high strength composite material. The most common material used in the construction of aircraft is aluminum (SAGES Module 2).

not always the case. So if dimpled golf balls do really give the edge to make them travel further distances what is the physics behind this phenomenon? So how does having dimples on the golf ball reduce drag? Firstly we have to look at the aerodynamics around golf balls‚ since the only force that can slow down a golf ball while in mid-air is the air flowing around the surface of it. We call these resistive forces drag forces‚ and there are two kinds which inevitably slow down spherical golf balls;

functioning properly at the same time‚ but more importantly‚ they must work in tandem to accomplish two things. First‚ the airplane must generate an amount of thrust that is equal to or greater than the amount of drag. (lect 1/31) Thrust is the aerodynamic force that moves an airplane forward through space. An airplane’s thrust is generated by its propulsion system—the more powerful the engine‚ the greater the thrust generated. Drag is the friction that resists the airplane’s motion as it is moving

furthest while meeting certain controlled variables. While the general term of flight refers to all aircraft‚ the experiment does not deal with powered aircraft. Due to this‚ paper airplanes should be looked at more like a glider or sailplane.(Aerodynamics of flight‚ n.d.) Considering that the design‚ and airframe of each aircraft will be different‚ this experiment specifically looks at the horizontal velocity as dictated by Bernoulli’s principle in relation to lift‚ and the principle of glide in

Air resistance is an opposing force often known as drag force. Air resistance acts in the opposite direction to snow skier’s velocity and can either harm or enhance performance of the athlete. The flow of air around an object causes the unavoidable effect of drag and is influenced by the size‚ shape‚ surface‚ and overall speed of an object (John Polson‚ 2013). Air resistance is present in snow skiers and can inhibit their performance in a race greatly if the proper precautions and positions are

construction‚ testing‚ and operation of vehicles operating in the Earth’s atmosphere or in outer space (Stanzione). Aerospace engineers can work on many different vehicles from aircraft to deep diving vessels to high speed trains. The vast knowledge in aerodynamics‚ propulsion systems‚ structural design‚ materials‚ avionics‚ and stability allows them to work on just about anything. To become an aerospace engineer one must complete a bachelor’s degree program‚ usually in aerospace or aeronautical engineering
