Aerodynamics, from Greek ἀήρ aer (air) + δυναμική (dynamics), is the study of motion of air, particularly as interaction with a solid object, such as an airplane wing. It is a sub-field of fluid dynamics and gas dynamics, and many aspects of aerodynamics theory are common to these fields. The term aerodynamics is often used synonymously with gas dynamics, the difference being that "gas dynamics" applies to the study of the motion of all gases, and is not limited to air. The formal study of aerodynamics began in the modern sense in the eighteenth century, although observations of fundamental concepts such as aerodynamic drag were recorded much earlier. Most of the early efforts in aerodynamics were directed toward achieving heavier-than-air flight, which was first demonstrated by Otto Lilienthal in 1891. Since then, the use of aerodynamics through mathematical analysis, empirical approximations, wind tunnel experimentation, and computer simulations has formed a rational basis for the development of heavier-than-air flight and a number of other technologies. Recent work in aerodynamics has focused on issues related to compressible flow, turbulence, and boundary layers and has become increasingly computational in nature.

Noise reduction conduit for static components in aircraft engines

Noise reduction conduit for non rotary components of aircraft engines, subjected to a characteristic range of temperatures of a gas turbine engine, constituted by an annular structure composed of an aerodynamic wet wall (10a, 10b), perforated and resistant mechanically and thermally; of a dry wall (12a, 12b), not resistant and of light weight; and of some intermediate elements to which both walls are mechanically attached and that define a jump or difference of temperature between the wet and dry walls; between which wet (10a, 10b) and dry walls (12a, 12b) there are partitions that define cavities (16a, 16b) isolated with regard to each other.

Turbine Blade With Recessed Tip

InactiveUS20090180887A1Improve performanceReduce heat loadBlade accessoriesLeakage preventionTurbine bladeAerodynamics

A turbine blade (1) with a side surface (7) having an aerodynamic profile. The turbine blade (1) further comprises an end surface (6) and is mounted in a turbine, whereby the end surface (6) is delimited by a gap from a casing (8) of the turbine. The end surface (6) comprises a recess (2) which is shaped such that it acts as an improved aerodynamic seal.

Airfoil Design for Wakeless Wind Turbine Tower Structures

InactiveUS20130156596A1Wind motor supports/mountsReaction enginesNacelleVertical axis

A novel wind turbine is provided that reduces or eliminates aerodynamic wake downwind of the tower to allow for the wind turbine to face away from the direction of the wind. The wind turbine comprises a tower and a rotor rotatably mounted to a nacelle which is mounted to the tower in stationary relationship therewith. The tower has a yaw bearing at its base so that it is rotatable about a vertical axis. In one embodiment the tower comprises a single airfoil symmetric about its major chord. In another embodiment the tower comprises a pair of spaced apart asymmetric airfoils defining a nozzle-like space there between through which a relatively high speed jet of air can travel to fill the aerodynamic wake zone behind the tower.

Aerodynamic noise reducing thin-skin landing gear structure

ActiveUS20170361924A1Wheel arrangementsUndercarriagesThinning skinAerodynamics

A landing gear assembly is also provided. The landing gear assembly may include a thin-skin support member defining a cavity and a cylindrical cavity. A cylinder may extend from the cylindrical cavity with an axle extending from the cylinder. A torsion link may be coupled to the axle and a torsion interface of the thin-skin support member.
