ANF Les Mureaux 170. The ANF Les Mureaux 170 was a prototype French fighter aircraft of the 1930s.  It was a single-engined, single-seat parasol monoplane, but only two were built, the type being rejected for service by the French Air Force.

Design and development

In 1930, the French Air Ministry issued a C.1 specification for a single-seat fighter, with the ability to reach 350 km/h (217 mph) and to be fitted with a supercharged engine. ANF Les Mureaux produced the ANF Les Mureaux 170, a parasol winged monoplane of all-metal construction powered by a single Hispano-Suiza 12Xbrs V12 engine. Its wings were slightly gulled and tapered out to give maximum chord and thickness midway along the wing, near where they were braced by struts to the fuselage. A fixed tailwheel undercarriage was fitted. The pilot sat in an open cockpit, and was armed by two Vickers machine guns mounted in the wings.

The first prototype flew on 19 November 1932, Although it demonstrated good performance, being described as the "fastest French service aircraft", it had a poor view from the cockpit when landing the aircraft, and despite a second prototype being flown in March 1934, the type was not chosen for production, with orders instead being placed for the Dewoitine D.500 and Blériot-SPAD S.510. It did, however, form the basis of the ANF Les Mureaux 180 two-seat fighter, also unsuccessful.

CIL Reghin Albatros. The CIL Reghin RG-9 Albatros was a tandem seat, all wood glider designed and produced in small numbers at the CIL (Complexu Industrializare Lemnului - Reghin) in Romania in the 1950s.

Design and development

The Albatros was a wooden glider with a cantilever mid-set wing.  The wings had a root chord of 1.60 m (5 ft 3 in), tapering to 0.66 m (2 ft 2 in) at the tip and carried 1.50° of dihedral. They were built around a single spar with a plywood covered leading edge torsion box in front of it and fabric covered behind.  The wing carried wooden, fabric covered ailerons and airbrakes.

The fuselage  of the Albatros was a plywood monocoque and the empennage was also wooden and fabric covered, with the tailplane set at the top of the fuselage.  The occupants sat in tandem under a continuous canopy with two separately sideways opening sections. It had a fixed undercarriage with two wheels on a short axle under the fuselage and an integral nose skid.  At rest, it sat on its wheels and tail.

The Albatros first flew on 1 June 1958.  In all, 25 were built.

John V. Wehausen. John Vrooman Wehausen (23 September 1913 – 6 October 2005) was an American applied mathematician considered to be one of the world's leading researchers and pioneers in the field of marine hydrodynamics. 

His contributions were in the area of ship waves, ship maneuverability, floating systems in waves, and ship-generated solitary waves. In 1960, he and Edmund V. Laitone published the comprehensive review article Surface Waves, which to this day is still an important resource for understanding the dynamics of water waves. Wehausen was emeritus professor of engineering science at the University of California, Berkeley.

Education and career
Wehausen matriculated at the University of Michigan where he earned B.S. (1934) and Ph.D. degrees in mathematics (1938) as well as an M.S. in physics (1935).
In 1937, Wehausen began his first teaching position as an instructor in mathematics at Brown University.
After Brown, Wehausen spent teaching stints at Columbia University and the University of Missouri before working for the U.S. Navy during World War II in operations research.
He joined the David Taylor Model Basin as a mathematician, and during his three-year tenure there, he met Georg P. Weinblum, the German ship hydrodynamicist. His interest in water-wave theory and ship hydrodynamics can be traced to that period.
He was an editor of the Annual Review of Fluid Mechanics from 1970–1976.

In 1956, Wehausen accepted a position at the University of California, Berkeley, where he taught until 1984 and where he remained an active researcher thereafter.
At Berkeley, Wehausen helped establish the Department of Naval Architecture in 1958 with support from the Office of Naval Research.
At the time, only three other U.S. institutions—Massachusetts Institute of Technology, the University of Michigan and the Webb Institute—offered accredited degree programs in naval architecture.

In 2002, a Special Symposium during the Offshore Mechanics and Arctic Engineering Conference in Oslo, Norway was organized as a tribute to Wehausen.

In 2006, a John V. Wehausen Memorial Endowment was established at the UC Berkeley Foundation to provide a scholarship for graduate study in Wehausen's areas of professional interest.

Personal
Wehausen loved languages, music, and literature. He was proficient in a number of languages and also was an
accomplished musician.

Ancillary Terrestrial Component. Ancillary Terrestrial Component (ATC) is a U.S. Federal Communications Commission-approved technique for using a "terrestrial" network of cell-phone towers to supplement a Mobile Satellite Service (MSS) provided by orbiting communications satellites. Satellite communications can be degraded by various factors, including attenuation in urban areas due to buildings etc. ATC allows the operators to reuse the same satellite spectrum in a terrestrial network to increase coverage and performance for their customers in highly shadowed regions e.g. within houses. In Europe ATC is known as complementary ground component (CGC).

Terasca. Terasca, or Terrier-ASROC-Cajun, was an American three-stage sounding rocket developed and launched by the United States Navy. Derived from a combination of the Terrier, ASROC and Cajun rockets, three launches were attempted during 1959, but only one was successful.

Design and development
The Terrier-ASROC-Cajun ("Terasca") rocket was developed during early 1959 by the Naval Ordnance Test Station, located at China Lake, California, to fill a U.S. Navy requirement for a three-stage sounding rocket, intended to launch experimental payloads for conducting high-altitude research. The rocket utilised a combination of existing missiles in its construction; the first stage was a Terrier surface-to-air missile; an ASROC anti-submarine rocket made up the second stage, while a Cajun sounding rocket was utilised as a third stage.

The Terrier first stage produced  thrust, while the ASROC second stage provided  , and the third-stage Cajun motor had a thrust rated at . The theoretical apogee for Terasca was ; it could carry a scientific payload of up to .

Operational history
Three launch attempts of the Terasca missile were made from the launch facility at Vandenberg Air Force Base during 1959, utilising the Western Launch and Test Range. The first launch attempt took place on May 1; this launch was a failure. A second launch attempt on June 26, however, was successful, with the rocket reaching an apogee of . A third launch, attempted on August 12, however, was also a failure; following the third launch, the Terasca program came to a close.

Iron(II,III) sulfide. Iron(II,III) sulfide is a blue-black (sometimes pinkish) chemical compound of iron and sulfur with formula Fe3S4 or FeS·Fe2S3, which is much similar to iron(II,III) oxide. It occurs naturally as the sulfide mineral greigite and is magnetic. It is a bio-mineral produced by and found in magnetotactic bacteria. It is a mixed valence compound, featuring both Fe2+ and Fe3+ centers, in 1:2 ratio.

Crystal structure
The crystallographic unit cell is cubic, with space group Fd3m. The S anions form a cubic close-packed lattice, and the Fe cations occupy both tetrahedral and octahedral sites.

Magnetic and electronic properties
Like the related oxide magnetite (Fe3O4), iron(II,III) sulfide is ferrimagnetic, with the spin magnetic moments of the  centers in the tetrahedral sites oriented in the opposite direction as those in the octahedral sites, and a net magnetization.  Both metal sites have high spin quantum numbers. The electronic structure of greigite is that of a half metal.

Oberlerchner Mg 23. The Oberlerchner Mg 23 is a single-seat, all-wood, high-performance sailplane. It was built and first flown in Austria in 1955, and a total of 26 were built before production ended in 1965.

Design and development
The Mg 23, an Erwin Musger design often known as the Musger Mg 23, was an all-wood shoulder-wing aircraft. Its wing had a straight leading edge, a constant-chord inner section with taper outboard and 2.5° of dihedral. The wingtips had small tip fences. It was built around a single wooden spar and was wood covered apart from the ailerons, which were fabric covered. Wooden Schempp-Hirth spoilers were fitted. The tail surfaces were fabric covered, the tailplane narrow in chord and straight tapered with a Flettner trim tab on the starboard elevator. One change between the prototype Mg 23 and the production Mg 23 SL was that the size of the fin and rudder was increased; on the SL the fin was straight-edged apart from a curved fuselage fillet but the trailing edge of the wide, deep rudder was rounded.

The fuselage had an oval section of wooden semi-monocoque construction, tapering to the rear. On the production SL the fuselage line over the wings merged into a forward-sliding canopy, which was longer than that of the prototype. The Mg 23 SL had a fixed monowheel undercarriage, and both integral nose- and tailskids.

The Mg 23 prototype flew on 25 June 1955, flight testing leading to the increase in vertical tail size and a modified canopy on the production aircraft, the first of which was flown on 1 April 1962.

Operational history

26 Mg 23 SLs had been built by March 1966. In mid-2010, 11 Mg 23s were on the civil registers of European countries, nine in Austria, one in Switzerland and one in the Netherlands. Three were exported to the United States and one to Canada.

Theodore Y. Wu. Theodore Yaotsu Wu (; March 20, 1924 – December 16, 2023) was a Chinese-born American engineer. He was a Professor of Engineering Science at the California Institute of Technology. His research contribution included compressible fluid flow, free-streamline theory of cavities, jets and wakes, water waves and free-surface flows, mechanics of fish swimming and bird/insect flight, wind and ocean-current energy, and internal waves in the ocean.

Early life
Wu came from a Chinese scholar family. His father had a degree in economics and finance, his mother graduated from high school and majored in literature, while his grandfather was a Chinese physician.

During the Japanese invasion, the Japanese airplanes flying overhead eventually inspired him to enter aeronautics in the university.

Education and career
Wu received his BSc in 1946 from National Chiao Tung University in Shanghai (now Shanghai Jiao Tong University), and spent one year teaching upon graduation. In January 1948 he arrived in the U.S. and enrolled at Iowa State University and graduated with an MS in December the same year. After Iowa, Wu went to Caltech, where he shared an office with Julian Cole. Wu was involved in the research group headed by Paco Lagerstrom, where they developed further the asymptotic perturbation method pioneered by Ludwig Prandtl.

Wu received his PhD in (1952), subsequently worked as a research fellow at Caltech for three years, and developed interest in water waves and hydrodynamics, due to inspiration from then Qian Xuesen and von Karman. After three years Wu became an assistant professor of applied mechanics (1955) at Caltech. In 1960, under the influence of G. I. Taylor and James Lighthill, Wu started to work on fish locomotion and bird flight (biofluiddynamics). During his time at Caltech he has also contributed to the field of naval architecture and been involved in the International Towing Tank Conferences.

Later life and death
Wu retired in 1996, but remained very active after his retirement. He died on December 16, 2023, at the age of 99.

Meitetsu 100 series. The  is a commuter electric multiple unit type operated by Nagoya Railroad (Meitetsu) in Japan since 1978. There is also a 200 series type, operated since 1991, which is very similar to the 100 series. The 100 series and 200 series trains run on the Inuyama Line and Toyota Line and provide through service to the Tsurumai Line in Nagoya Municipal Subway.

History

Background

In the 1950s, Toyota saw a surge in population thanks to its local car industry. Despite this increase, no railway connected Toyota to Nagoya, forcing local residents to use cars. The area around Nagoya suffered from frequent traffic congestions due to spike in automobile usage. After a proposal in 1972 proposing around 139km of railway network around Nagoya including existing lines, Meitetsu gave away construction permits for the section between Yagoto and Akaike which was inherited from one of the railway companies Meitetsu absorbed to the Nagoya Municipal Subway, while also building the section between Akaike and Toyotashi Station. The two groups agreed to run through service from Toyotashi to Kami-Otai, which went through the Tsurumai Line and Meitetsu Toyota Line. The Meitetsu 100 series was designed for this through service.

Cajun (rocket). The Cajun was an American sounding rocket developed during the 1950s. It was extensively used for scientific experiments by NASA and the United States military between 1956 and 1976.

Development
Development of the Cajun sounding rocket began in early 1956 at the Pilotless Aircraft Research Division (PARD) of the National Advisory Committee for Aeronautics' - later NASA - Langley Research Center, as a development of the earlier Deacon experimental rocket. Utilising the Deacon's airframe but an improved motor that utilised new, higher-energy propellants to provide better performance, the name "Cajun" was applied to the rocket by the leader of PARD's rocket division, a native of New Orleans.

The Cajun rocket was constructed of stainless steel, with extruded Duraluminum stabilising fins. The rocket motor, developed by Thiokol, was capable of producing up to  thrust.

Operational history
The first test launch of the Cajun rocket took place at the Wallops Island range in Virginia on June 20, 1956. The rocket proved to be as successful as expected, and was quickly put into extensive use, both on its own and as an upper stage in the Nike Cajun (or CAN, 'Cajun And Nike'), first launched on July 6, 1956; and in the Terasca three-stage rocket, first launched May 1, 1959. Several other sounding rocket configurations made use of the Cajun stage, the most extensively used being the Cajun Dart; the Bullpup-Cajun and Double Cajun rockets also utilised the stage.

In total, over eight hundred launches of the Cajun rocket in its various configurations were conducted between 1956 and October 6, 1976, when the final Cajun flight, in the Nike-Cajun configuration, was undertaken at Wallops Island.
