Boeing Phantom Works has partnered with NASA and the Air Force Research Laboratory to study the structural, aerodynamic and operational advantages of the Blended Wing Body concept, a cross between a conventional plane and a flying wing design. The Air Force has designated the prototype the X-48B based on its interest in the design's potential as a multi-role, long-range, high-capacity military transport aircraft.
The X-48B Blended Wing Body technology demonstration aircraft was built by Cranfield Aerospace in the United Kingdom to Boeing's specifications. The subscale prototypes have a wingspan of 20.4 feet, with prominent vertical fins and rudders at the wingtips and elevons along the trailing edges of the wings. Three small model aircraft turbojet engines, providing a maximum combined thrust of about 160 lbs, power the 523-lb. gross weight aircraft. The X-48B has an estimated top airspeed of 118 knots (138 mph), a maximum altitude of about 10,000 feet and a flight duration of about 40 minutes.

avrocar

The VZ-9- AV Avrocar was a Canadian VTOL aircraft developed by Avro Aircraft as part of a secret US military project carried out in the early years of the Cold War. Two prototypes were built as "proof-of-concept" test vehicles for more advanced USAF fighter and US Army tactical combat aircraft. The Avrocar intended to exploit the Coandă effect to provide lift and thrust from a single "turborotor." Thrust from the rotor was diverted out the rim of the disk-shaped aircraft to provide anticipated VTOL-like performance. In the air, it would have resembled a flying saucer. In flight testing, the Avrocar proved to have unresolved thrust and stability problems that limited it to a degraded, low-performance flight envelope; subsequently, the project ended ignominiously with the program cancellation in 1961.

sr-71 blackbird


The SR-71 remained the world's fastest and highest-flying operational manned aircraft throughout its career. From an altitude of 80,000 ft (24 km) it could survey 100,000 square miles per hour (72 square kilometers per second) of the Earth's surface. On 28 July 1976, an SR-71 broke the world record for its class: an absolute speed record of 2,193.1669 mph (3,529.56 km/h), and a US "absolute altitude record" of 85,068.997 feet (25,929 m). Several planes exceeded this altitude in zoom climbs but not in sustained flight. When the SR-71 was retired in 1990, one was flown from its birthplace at United States Air Force Plant 42 in Palmdale, California to go on exhibit at what is now the Smithsonian Institution's Steven F. Udvar-Hazy Center (an annex of the National Air & Space Museum) in Chantilly, Virginia. The Blackbird, piloted by Colonel Ed Yielding and Lt. Col. J.T. Vida, set a coast-to-coast speed record at an average 2,124 mph (3,418 km/h). The entire trip was reported as 68 minutes and 17 seconds. Three additional records were set within segments of the flight, including a new absolute top speed of 2,242 mph measured between the radar gates set up in St. Louis and Cincinnati. These were accepted by the National Aeronautic Association (NAA), the recognized body for aviation records in the United States. An enthusiast site devoted to the Blackbird lists a record time of 64 minutes. The SR-71 also holds the record for flying from New York to London: 1 hour 54 minutes and 56.4 seconds, set on 1 September 1974. This is only Mach 2.68, well below the declassified figure of 3.0+. (For comparison, commercial Concorde flights took around 3 hours 20 minutes, and the Boeing 747 averages 6 hours.)

YB49



The Northrop YB-49 was a prototype jet-powered flying wing medium bomber aircraft developed by Northrop for the United States Air Force shortly after World War II. It was a development of the piston-engined YB-35, and the two YB-49s actually built were both converted YB-35 test aircraft. The aircraft was never to enter production, however, being passed over in favor of the more conventional Convair B-36 in service.

USS Iowa (BB-61), the lead ship of the U.S. Navy's last class of battleship, was the fourth ship of the same name to serve in the United States Navy, but the second to be commissioned, to be named in honor of the 29th state.
Iowa's
keel was laid down on 27 June 1940 at the New York Navy Yard. Nicknamed "The Big Stick," the battleship was launched on 27 August 1942 sponsored by Ilo Wallace (wife of Vice President Henry Wallace), and commissioned on 22 February 1943 with Capt. John L. McCrea in command.

Iowa earned nine battle stars for World War II service and two for Korean War service.
