Aerodynamics

Summary: Aerodynamics is the study of the behavior of air and other gases in motion, particularly as it relates to the design, construction, and performance of aircraft, missiles, and other vehicles that move through the air. The field encompasses a wide range of topics, including lift, drag, and stability, as well as the effects of airflow on objects in motion. Aerodynamics is a critical discipline in engineering, with applications in aerospace, automotive, and other industries.

Subsonic Aerodynamics

Title: Subsonic Aerodynamics

Summary: Subsonic aerodynamics deals with the behavior of aircraft and other vehicles that travel at speeds below the speed of sound. Key concepts include drag reduction, lift, and the design of wings and other aerodynamic surfaces. Notable works in this area include Katz’s “Low-Speed Aerodynamics” and Ferri’s “Elements of Aerodynamics of Supersonic Flows.”

Aeroelasticity

Title: Aeroelasticity

Summary: Aeroelasticity is the study of the interaction between aerodynamic forces, structural flexibility, and inertial forces in aircraft and other vehicles. Key concepts include flutter, divergence, and the design of structures that can withstand the forces experienced during flight. Notable works in this area include Bisplinghoff, Ashley, and Halfman’s “Aeroelasticity.”

Automotive Aerodynamics

Title: Automotive Aerodynamics

Summary: Automotive aerodynamics is the study of the aerodynamics of road vehicles, with the main goals being reducing drag, wind noise, minimizing noise emission, and preventing undesired lift forces and other causes of aerodynamic instability at high speeds. Key concepts include the use of computer modeling and wind tunnel testing, as well as the design of vehicles to meet specific design constraints such as safety standards and regulations.

Ground Effect (Aerodynamics)

Title: Ground Effect (Aerodynamics)

Summary: Ground effect is a phenomenon that occurs when an aircraft flies close to the ground, resulting in an increase in lift and a decrease in drag. Key concepts include the “ram” or “cushion” effect, which increases air pressure on the lower wing surface, and the resulting improvement in the aircraft’s lift-to-drag ratio. Ground effect is particularly important in the design of VTOL (Vertical Takeoff and Landing) aircraft.

Aerodynamics (Ancient Greek: ἀήρ aero (air) + Ancient Greek: δυναμική (dynamics)) is the study of the motion of air, particularly when affected by a solid object, such as an airplane wing. It involves topics covered in the field of fluid dynamics and its subfield of gas dynamics, and is an important domain of study in aeronautics. 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.
