Aerodynamics is also important in the prediction of forces and moments acting on sailing vessels. It is used in the design of mechanical components such as hard drive heads. Structural engineers resort to aerodynamics, and particularly aeroelasticity, when calculating wind loads in the design of large buildings, bridges, and wind turbines.
NASA Paresev, a Rogallo flexible wing tested by NASA for spacecraft landing research.. The Rogallo wing is a flexible type of wing.In 1948, Francis Rogallo, a NASA engineer, and his wife Gertrude Rogallo, invented a self-inflating flexible wing they called the Parawing, also known after them as the "Rogallo Wing" and flexible wing.

The science of aerodynamics deals with the motion of air and the way that it interacts with objects in motion, such as an aircraft. The study of aerodynamics falls broadly into three areas: Incompressible flow occurs where the air simply moves to avoid objects, typically at subsonic speeds below that of sound (Mach 1).
Each episode is typically a half hour and features special guests and different science, math, engineering or technology topics. [ 3 ] Since first broadcasting in 2014, the program has covered dozens of topics including the NASA 's Apollo program , Tuskegee Airmen , astronaut training, the Wright brothers and the Orion program.

In aerodynamics, the torques or moments acting on an airfoil moving through a fluid can be accounted for by the net lift and net drag applied at some point on the airfoil, and a separate net pitching moment about that point whose magnitude varies with the choice of where the lift is chosen to be applied.
For fixed-wing aircraft, ground effect is the reduced aerodynamic drag that an aircraft's wings generate when they are close to a fixed surface. [1] During takeoff, ground effect can cause the aircraft to "float" while below the recommended climb speed.
The aerodynamics of the canard configuration are complex and require careful analysis. Rather than use the conventional tailplane configuration found on most aircraft, an aircraft designer may adopt the canard configuration to reduce the main wing loading, to better control the main wing airflow, or to increase the aircraft's maneuverability ...
The NASA Oblique Wing Research Aircraft, the predecessor to the AD-1. The first known oblique wing design was the Blohm & Voss P.202, proposed by Richard Vogt in 1942. [1] The oblique wing concept was later promoted by Robert T. Jones, an aeronautical engineer at NASA's Ames Research Center, Moffett Field, California. Analytical and wind tunnel ...
