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. The acronym is a reference to early German Aerospace Engineer Ludwig Prandtl , whose theory of the bell-shaped lift distribution deeply influenced Bowers.

1188-416: A revision was created and a second draft proposed. This second revision was greeted with a large amount of Congressional involvement that resulted in line-by-line reviews of the script, which led to the less radical display that was seen in 1995. This was not met without resistance from the scholarly community, though. The Organization of American Historians felt as if Congress's attempts to police and penalize

1287-671: A successful review of the program. The Smithsonian specifically requested the aircraft because of its innovative proverse-yaw design.

The National Museum of Natural History opened in June 1911 to similarly accommodate the Smithsonian's United States National Museum, which had previously been housed in the Castle and then the Arts and Industries Building. This structure was designed by the D.C. architectural firm of Hornblower & Marshall . When Detroit philanthropist Charles Lang Freer donated his private collection to

5247-411: The Smithsonian's museums and research centers. The center is a division of the Smithsonian Institution. As of May 2016, the center is run by an executive director, Eduardo Díaz. At the time of its creation, the Smithsonian Institution had other entities dedicated to other minority groups: National Museum of the American Indian, Freer-Sackler Gallery for Asian Arts and Culture, African Art Museum, and

5346-416: The Smithsonian, slightly increased from previous years. Institution exhibits are free of charge, though in 2010 the Deficit Commission recommended admission fees. As approved by Congress on August 10, 1846, the legislation that created the Smithsonian Institution called for the creation of a Board of Regents to govern and administer the organization. This seventeen-member board meets at least four times

5445-532: The Smithsonian. Though the Smithsonian's first secretary, Joseph Henry , wanted the institution to be a center for scientific research, it also became the depository for various Washington and U.S. government collections. The United States Exploring Expedition by the U.S. Navy circumnavigated the globe between 1838 and 1842. The voyage amassed thousands of animal specimens, an herbarium of 50,000 plant specimens, and diverse shells and minerals, tropical birds, jars of seawater, and ethnographic artifacts from

5544-414: The United States. Reports were to be published periodically to share this knowledge with the greater public, but due to a lack of funds, this initially did not occur. The institute first met in Blodget's Hotel, later in the Treasury Department and City Hall, before being assigned a permanent home in 1824 in the Capitol building. Beginning in 1825, weekly sittings were arranged during sessions of Congress for

5643-468: The air. Bulldozers from Fort Belvoir and prefabricated buildings from the United States Navy kept the initial costs low. The museum's prominent site on the National Mall once housed the city's armory, which became Armory Square Hospital during the Civil War; it nursed the worst wounded cases who were transported to Washington after battles. The rest of the site was occupied by a cluster of temporary war buildings that existed from World War I until

5742-412: The aircraft is based on the flight of a bird. The Prandtl-D No. 3 first flew Oct. 28, 2015, with double the wingspan of the earlier versions, however, through development, the team managed to reduce the final glider's drag by 11%. Initially, each aircraft was radio operated with a hobby-grade controller and launched with a bungee cord system. Later flight tests switched from a bungee launch method to

5841-489: The building. The museum's glass curtain walls (among those elements of the 1976 structure whose design was altered for cost reasons) are too permeable to ultraviolet radiation. Several exhibits (such as the spacesuit worn by John Young during the Gemini 10 mission, and the coating on the Spirit of St. Louis aircraft) have been damaged by this radiation. Additionally, the Smithsonian's report noted that cutbacks in building design prior to and during construction left

5940-489: The construction of the Arts and Industries Building in 1881. Congress had promised to build a new structure for the museum if the 1876 Philadelphia Centennial Exposition generated enough income. It did, and the building was designed by architects Adolf Cluss and Paul Schulze, based on original plans developed by Major General Montgomery C. Meigs of the United States Army Corps of Engineers . It opened in 1881. The National Zoological Park opened in 1889 to accommodate

That same year, the Smithsonian signed an agreement to take over the Cooper Union Museum for the Arts of Decoration (now the Cooper Hewitt, Smithsonian Design Museum ). The National Portrait Gallery and the Smithsonian American Art Museum opened in the Old Patent Office Building (built in 1867) on October 7, 1968. The reuse of an older building continued with

7029-425: The institution's endowment had a total value of about $ 5.4 billion. In many ways, the origin of the Smithsonian Institution can be traced to a group of Washington citizens who, being "impressed with the importance of forming an association for promoting useful knowledge," met on June 28, 1816, to establish the Columbian Institute for the Promotion of Arts and Sciences . Officers were elected in October 1816, and

7128-557: The large numbers of aircraft donated to the Smithsonian after World War II and the need for hangar and factory space for the Korean War drove the Smithsonian to look for its own facility to store and restore aircraft. The current Garber Facility was ceded to the Smithsonian by the Maryland-National Capital Park and Planning Commission in 1952 after the curator Paul E. Garber spotted the wooded area from
