McDonnell Douglas DC-X. The DC-X, short for Delta Clipper or Delta Clipper Experimental, was an uncrewed prototype of a reusable single-stage-to-orbit launch vehicle built by McDonnell Douglas in conjunction with the United States Department of Defense 's Strategic Defense Initiative Organization (SDIO) from 1991 to 1993.
Fleet overview. Delta operates the largest fleets of the Airbus A220, Boeing 717, and Boeing 757, the largest passenger fleet of the Boeing 767, and the largest Airbus A330 fleet of any US airline. [7][8][9][10] Alongside United Airlines, it is one of only two airlines operating the Boeing 767-400ER. Delta primarily uses narrow-body aircraft ...
This followed the retirement of Delta II in 2018 and single-stick (non-Heavy) variants of the Delta IV in 2019. With the start of 2024, Vulcan Centaur took its first flight in time to maintain continuity of ULA's service in the heavy-lift launch vehicle market before the Delta IV Heavy program came to an end three months later on April 9, 2024.
EtherNet/IP is one of the leading industrial protocols in the United States and is widely used in a range of industries including factory, hybrid and process. The EtherNet/IP and CIP technologies are managed by ODVA, Inc., a global trade and standards development organization founded in 1995 with over 300 corporate members.
Ethernet packet. The SFD (start frame delimiter) marks the end of the packet preamble. It is immediately followed by the Ethernet frame, which starts with the destination MAC address. [1] In computer networking, an Ethernet frame is a data link layer protocol data unit and uses the underlying Ethernet physical layer transport
Terabit Ethernet (TbE) is Ethernet with speeds above 100 Gigabit Ethernet. The 400 Gigabit Ethernet (400G, 400GbE) and 200 Gigabit Ethernet (200G, 200GbE) [ 1 ] standard developed by the IEEE P802.3bs Task Force using broadly similar technology to 100 Gigabit Ethernet [ 2 ][ 3 ] was approved on December 6, 2017. [ 4 ][ 5 ] On February 16, 2024 ...
The Ethernet physical layer has evolved over its existence starting in 1980 and encompasses multiple physical media interfaces and several orders of magnitude of speed from 1 Mbit/s to 400 Gbit/s. The physical medium ranges from bulky coaxial cable to twisted pair and optical fiber with a standardized reach of up to 80 km.
The DC-XA Clipper Graham. Between 1993 and 1996, the McDonnell Douglas DC-X, also known as the "Delta Clipper", conducted twelve low-altitude suborbital test launches to verify the configuration and handling of the uncrewed single-stage-to-orbit Delta Clipper design, which was proposed to the United States Department of Defense and the National Aeronautics and Space Administration (NASA) for ...
