Testbeds are also pages on the Internet where the public are given the opportunity to test CSS or HTML they have created and want to preview the results.
Boeing's bid of $3 per lb was much less than any of the competing bids, and Boeing was awarded the San Francisco to Chicago contract in January 1927, building 24 Model 40As for the route (with a further aircraft being used as a testbed by Pratt & Whitney).
The other prototype is now on display at the Aeronautical Museum of Vigna di Valle near Rome and the ground testbed is at the Museum of Science and Technology in Milan.
Communications, Navigation, and Networking reConfigurable Testbed (CoNNeCT), a testbed for the Space Communications and Navigation Program (SCaN) program on the International Space Station
Transferred to NASA in the early 1960s, one was used as a testbed for the American supersonic transport program, fitted with an ogival wing platform (the type eventually used on Concorde; data from the program was shared with the European designers).
Research on new algorithm developments and evaluations is performed at the ITS Centre and Testbed (ICAT), at the Civil Engineering department of the University of Toronto.
Interest in the HP.52 by the Swedish for placing a potential order led to the HP.53 prototype, which was subsequently used as a testbed for a pair of 1,000 hp (750 kW) Napier Dagger VIII 24-cylinder H-block air-cooled inline engines.
LACE was studied to some extent in the USA during the late 1950s and early 1960s, and by late 1960 Marquardt had a testbed system running.
•
Both Marquardt and General Dynamics were involved in the research, and by late 1960 Marquardt had a testbed system running that was capable of running a 275 lbf (1.2 kN) thrust engine for minutes at a time.
The AiRover Altair, dubbed The Flying Testbed, was powered by a Menasco Unitwin engine, which used two engines to drive a single shaft.
In order to prove the design, Griffith and several other engineers at the Royal Aircraft Establishment built a testbed example of the compressor in 1928 known as Anne, the machinery being built for them by Fraser and Chalmers.
In 1983, 956 chassis #107 was used by Porsche as a testbed for their P01 Formula One engine, later badged as TAG and used exclusively by McLaren.
Some NASA projects using it include the James Webb Space Telescope, Swift's Burst Alert Telescope, the Lunar Reconnaissance Orbiter, LCROSS, the Geostationary Operational Environmental Satellite (GOES-R), and the SCaN Testbed, previously know as the Communications, Navigation, and Networking Reconfigurable Testbed (CoNNeCT).
However, with the reduction in military orders due to the approaching end of the war, no production contract was placed, and the aircraft was used as an engine testbed for the USAAF as well as being evaluated by the U.S. Navy in comparison with other contemporary attack aircraft, especially the Douglas AD-1 Skyraider and Martin AM-1 Mauler.
