Aerodynamics is the branch of dynamics that deals with the motion of air and other gaseous fluids and with the forces acting on bodies in motion relative to such fluids. The Latin word for aero means air, and the Latin word for dynamics means power.
Steady aerodynamics this term is used to describe situations where there is no rapid change in properties over time. For example, an aircraft cruising straight and level in the upper atmosphere, well above where any gust can reach it. When such situations are being analyzed, a lot of effort can be saved by neglecting terms in the equations, which describe rates of change of the flow properties or forces at any point on the aircraft.
Time-accurate strong-interaction models for the coupling of a boundary-layer method with a method for three-dimensional, unsteady, compressible potential flow about elastically deforming wings are developed. The investigation of the flow behind on oscillating airfoil has shown that two waves of convected vortices can be distinguished: One wave convected at, roughly, the outside uniform velocity; and an inner wave in the core of the wake originating at the trailing edge which is convected at a much lower speed. At a certain distance behind the airfoil there is a partially destructive interference, which depends on the reduced frequency. For the flow above a circle-cylinder it is shown that giving small symmetric displacements from its equilibrium position to a vortex pair positioned near the circle-cylinder, periodic oscillations set in. Expressions for closed orbits and their periods are obtained. For the large amplitude case the vortex trajectories are calculated numerically. For a circle-cylinder with strakes the vortex motions may be periodic, quasi-periodic or the vortices may be swept away, depending on the initial conditions. From the equations of motion of flexible slender bodies with constant crosssections immersed in a uniform axial flow, expressions have been derived for the divergence speed and for the flutter speed.
Aerodynamics is the study of motion of gas on objects and the forces created. The same principles that let air planes fly is used in racing cars. The difference is the wing is mounted upside down to keep down force on the car instead of lift. Downforce is ver...

Aerodynamics is the physics of non-fluids (solids) moving through gaseous fluids. Finally, Air resistance falls within Aerodynamics as being the specific study of the forces opposing an objects motion through a gas. ... Aerodynamics is a very complex field, and I found many different equations, each claiming to be the basic equation of fluid friction or air resistance. of them, the most basic is Fd=KV2 where Fd is the force of drag, K is the constant of friction, and V is the velocity relative to the gas. ...
The aerodynamics a stock car goes through during a race displays fundamentals in fluid mechanics. The car experiences drafts, drag, ground effect and down forces. Aerodynamic Factors: • Down Force • Drag • Ground Effect • Draft Figure 1 (Pressure Differentials) Airfl...
To the educated, an aircraft propeller represents the highest sophistication in aerodynamics, mechanical engineering and structural design. ... Other experimenters, who were convinced that man flight should have wings, worked to establish basic principles in aerodynamics, flight stability and control, as well as propulsion. ... Another important milestone in aviation, was the understanding of aerodynamics. Sir George Cayley, a British theorist, was acclaimed as the father of aerodynamics. ... More importantly, Turnbull confirmed the universal law of aerodynamics: the ef...
Greater flexibility of late Cold War fighter operations was facilitated by improved, and more extensive, training. In the US, this was first seen in the upgrading of individual aircraft tactics and aircrew performance that eventually led to the improvement in kill ratios over the NVAF in...
Workers in this field need to have skills in aerodynamics and need to know the best way to build things for fuel efficiency and the best way to carry cargo. ... Math is a very big part in aerodynamics like calculus, and algebra. ...
We know about aerodynamics and the four forces that plays a part in flight which are Thrust, Lift, Drag, and Weight. ... My group did well together because we all understood aqua dynamics, aerodynamics, and the four force of flight prior to our past lessons in Marine Biology with Homer and Teressa. ...
