DARPA launched the project in mid-2022, wanting a plane that could lift large, heavy loads by skimming the water in ground effect, and capable of operating at mid-altitudes of up to 10,000 feet (3,000 m). Utilizing the ground effect, flying at an altitude equal to 5% of the wingspan can deliver 2.3 times more efficient flight performance.
[1] [4] A stick & tissue balsa model airplane under construction, still manufactured by Guillow's. During World War II, the supply of balsa wood was diverted to the war effort for the manufacture of rafts and life jackets. Guillow's was forced to use alternative materials like cardboard or pine wood to manufacture the model kits.
As used here, an experimental or research and development aircraft, sometimes also called an X-plane, is one which is designed or substantially adapted to investigate novel flight technologies. [ 1 ] [ 2 ] [ 3 ]
A series of experimental hypersonic projects, including an advanced version of the Martin Marietta X-24 lifting body, were turned down. Eventually issues with the Rockwell HiMAT advanced UAV led to a crewed X-plane with forward sweep, the Grumman X-29, which flew in 1984. [5]
[1] [2] Alberto Santos-Dumont was the first to offer for free construction plans, publishing drawings of his Demoiselle in the June 1910 edition of Popular Mechanics. [6] The first aircraft to be offered for sale as plans, rather than a completed airframe, was the Baby Ace in the late 1920s. [7]
In May 2017, X-Plane 11 was released, a major iteration in their flight simulator. X-Plane 11 is available in both a consumer version, as well as a Federal Aviation Administration certifiable professional version. [5] In January 2022, Laminar Research announced the release of their upcoming next-generation simulation game, X-Plane 12. It is ...
First flight of the full-sized aircraft was originally forecast in 2009 for 2010, but by July 2012 only a 1/4 scale model had been flown. [ 3 ] [ 5 ] In February 2014 the design had passed through the final round of wind tunnel testing, and in March 2014 the first carbon fiber parts were made for the conforming flying prototype.
The S-550 was a proposed crewed space capsule, designed in 2005-06 at Venturer Aerospace, in response to the NASA Commercial Orbital Transportation Services (COTS) program to provide commercial resupply and logistics support for the International Space Station after the retirement of the Space Shuttle.
