The Preliminary Research Aerodynamic Design to Lower Drag, or Prandtl-D was a series of unmanned experimental glider-aircraft developed by NASA under aerodynamicist Albion Bowers. [1] The acronym is a reference to early German Aerospace Engineer Ludwig Prandtl , whose theory of the bell-shaped lift distribution deeply influenced Bowers.
Robert T. Jones, (May 28, 1910 – August 11, 1999), was an American aerodynamicist and aeronautical engineer for NACA and later NASA. [1] He was known at NASA as "one of the premier aeronautical engineers of the twentieth century". [2]
The Whitcomb Area Rule: NACA Aerodynamics Research and Innovation, History Nasa. Whitcomb, Richard T. (January 1956). A Study of the Zero-Lift Drag-Rise Characteristics of Wing-Body Combinations Near the Speed of Sound (Technical report). National Advisory Committee for Aeronautics. hdl: 2060/19930092271 – via NASA Technical Reports Server.
Flight dynamics calculations are handled by computerized guidance systems aboard the vehicle; the status of the flight dynamics is monitored on the ground during powered maneuvers by a member of the flight controller team known in NASA's Human Spaceflight Center as the flight dynamics officer, or in the European Space Agency as the spacecraft ...
After World War II, NACA research began to focus on near-sonic and low-supersonic airflow.After considering the sudden drag increase which a wing-fuselage combination experiences at somewhere around 500 mph (800 km/h), Whitcomb concluded that "the disturbances and shock waves are simply a function of the longitudinal variation of the cross-sectional area" – that is, the effect of the wings ...
The ESA/ESO/NASA FITS (Flexible Image Transport System) Liberator is a free software program for processing and editing astronomical data in the FITS format to reproduce images of the universe. Version 3 [ 1 ] and later are standalone programs; earlier versions were plugins for Adobe Photoshop .
OVERFLOW - the OVERset grid FLOW solver - is a software package for simulating fluid flow around solid bodies using computational fluid dynamics (CFD). It is a compressible 3-D flow solver that solves the time-dependent, Reynolds-averaged, Navier–Stokes equations using multiple overset structured grids.
Experimental Aerodynamics Laboratory (EAL) – Housed in a dedicated research building adjacent to the Department’s Aerospace Engineering Sciences Building and containing a low-speed wind tunnel, the EAL is devoted to improving production, understanding, and control of complex flow fields in aerodynamic applications.
