Anatra DM Anamon. The Anatra Anamon was a Russian prototype monoplane fighter built by the A.A. Anatra factory in World War I.

Design 
The Anamon was a single-seat monoplane fighter of slim plywood fuselage and mid-placed trapezoid wing with cut out viewing aperture. The landing gear was similar to that designed for the Anatra D.

Test flights of the Anatra Anamon began June 16, 1916, but pilots complained about the 'long' (150m) takeoff and landing Roll as well as steep gliding. The deep pilot's position also was not appreciated. Improvements were suggested, but after minor damage such plans were axed.

China Railways FD. The China Railways FD class of locomotives were 2-10-2 steam locomotives of the FD locomotive type imported from the Soviet Union and regauged for use in China.

History
The FD class locomotives were imported from the Soviet Union to China from 1958 to provide main line freight motive power for the Chinese railways. Over 1000 units were acquired and remained in service until 1985.

When imported the class were designated YH (YouHao meaning 'friendship'), but after the breakdown of Sino-Soviet relations during the Cultural Revolution (see Sino–Soviet split) the class were renamed FX (FanXiu meaning 'anti-revisionist'). In 1971 the class were returned to the original Soviet designation of 'FD' (after Felix Dzerzhinsky).

Coastline (sculpture). Coastline is an outdoor sculpture by American artist Jim Sanborn installed at the National Oceanic and Atmospheric Administration complex in Silver Spring, Maryland.

Coastline attempts to recreate the effect of waves crashing on the Atlantic coast (represented by rough-cut granite). This is achieved with artificial waves generated by a turbine and pneumatic blower underneath the sculpture. The wave frequency is controlled by a remote tide gauge in Woods Hole, Massachusetts, that sends actual wave heights to the sculpture's control mechanism in real time. Sanborn built a quarter-size scale model of the sculpture and consulted with a wave engineer while doing research for the project.

AAM-A-1 Firebird. The AAM-A-1 Firebird was an early American air-to-air missile, developed by the Ryan Aeronautical Company. The first air-to-air missile program developed for the United States Air Force, the Firebird was extensively tested in the late 1940s; although it proved successful in testing, it was soon obsolete due to the rapid advances in aircraft and missile technology at the time and did not enter production.

Design and development
The AAM-A-1 project began in 1946 with the awarding of a study contract, under the designation MX-799, to the Ryan Aeronautical Company for the development of a subsonic air-to-air missile, which would be used by interceptor aircraft for the destruction of enemy bombers. A contract for the development of the missile, designated AAM-A-1 Firebird, was awarded in 1947.

The AAM-A-1 Firebird was a two-stage weapon, fitted with cruciform wings and tailfins. Control was by differential motion of the wings; the tailfins were fixed. The missile's fuselage was constructed from aluminum alloy, while the nosecone and control fins were molded from plastic. Firebird was fitted with a solid-fuel booster rocket providing initial thrust, before a liquid-fuel sustainer rocket ignited for a 15-second powered flight time.

Guidance was provided during midcourse flight by radio command, with an operator in the launching aircraft transmitting corrections to the missile. Terminal guidance used active radar homing, with a small radar set fitted in the nose of the missile, with the missile's warhead being detonated by a proximity fuze, a backup impact fuze also being fitted.

Operational history
Flight testing of the XAAM-A-1 prototype missiles began in October 1947, launched from DB-26 Invader bomber and DF-82 Twin Mustang aircraft, the latter of which could carry up to four missiles. The first air-to-air missile to reach the flight-test stage outside of World War II Nazi Germany, the Firebird proved to be reasonably successful in testing, with production being projected for the early 1950s; however its command-guidance system limited it to clear-weather, daytime use only.

Although radar beam riding guidance was planned to solve this, the subsonic speed of the weapon was also considered to be insufficient to avoid obsolescence; accordingly, the AAM-A-1's production program was terminated late in 1949, the Hughes Falcon being selected for development as the Air Force's standard intercept missile instead. The test program was considered to be successful, despite the rejection by the USAF, as a considerable amount of knowledge was gained that benefited later programs.

A Firebird missile is preserved at the Air Force Space & Missile Museum at Cape Canaveral Air Force Station in Florida.

Hanriot HD.6. The Hanriot HD.6 was a French two-seat fighter aircraft prototype, built towards the end of World War I though not flown until after the armistice with Germany. A biplane with an unusually narrow gap between upper and lower wings, powered by a single water-cooled radial engine, it did not enter production.

Design and development
The Hanriot HD.6 was rather like a scaled-up (by nearly 30% in span), more powerful version of the  HD.5.  Both were two-seat fighters and biplanes with equal span upper and lower wings. The unstaggered wings were divided into two bays on each side by two pairs of parallel interplane struts; bracing was assisted by wires. Their  wings were almost rectangular in plan, with squared wing tips on the HD.6 though the rounded tips of its short span, horn balanced ailerons, mounted on both upper and lower planes, projected beyond. On both designs the interplane gap was unusually small, with the upper wing so close to the fuselage that its leading edge required a deep, slot like cut-out for the pilot's head. Behind him the trailing edge also had a cut-out, this for the movement of the rear gunner's two dorsal Lewis guns; he also had a single, ventrally mounted Lewis gun. From gunner to tail, the fuselage of the HD.5 had rounded decking.  The fighter's braced, rectangular tailplane, mounted on top of the fuselage had projecting horn balances on its elevators like those on the ailerons.  The fin was small but the rudder was broad chord and low; it was very rounded and extended down to the keel, so there was an elevator cut-out for rudder movement.

The HD.6 was powered by a  Salmson 18Z two row, 18-cylinder radial engine, water-cooled by three circular section radiators mounted between the legs of its fixed conventional undercarriage.  This had mainwheels on a single axle attached by V-struts to the lower fuselage, assisted by a tailskid.

Built at about the same time as the HD.5, the first flight of the sole prototype was delayed by over a year owing to development difficulties with the novel engine.  Beginning in the spring of 1919, flight testing lasted into the late summer, when further development was abandoned.

Quicksilver GT500. The Quicksilver GT500 is a family of American strut-braced, high-wing, pusher configuration, tricycle gear aircraft built by Quicksilver Aeronautics of Temecula, California. The aircraft is available as a kit for amateur construction or as a completed ready-to-fly aircraft.

Design and development
The GT500 was developed specifically for the Sportplane class of the primary aircraft category (Part 21.24 of the Federal Aviation Regulations) and, on 26 July 1994, became the first aircraft certified in that category. Reviewer Noel Bertrand wrote, "[It] may sound like a very dry achievement, but actually speaks volumes for its design integrity. Not surprisingly its flight behaviour is excellent."

The aircraft's nomenclature is unclear as the manufacturer refers to it variously as the GT500, GT 500 and the GT-500. The FAA certification officially calls it the GT500.

The GT500 is constructed from aluminium tubing, which is bolted together. The aircraft is covered in pre-sewn Dacron envelopes, with the forward fuselage made from fiberglass. The wing features half-span ailerons and half-span flaps. The GT500 has two seats in tandem, with dual controls featuring control columns with yokes. A 1991 upgrade included optional doors that are zippered into place adding  of cruise speed, steel landing gear legs with dual brakes and an electric starter.

Variants
GT400
Single-seat version equipped with a  Rotax 447 two-stroke or  Rotax 503 two-stroke engine. Standard empty weight is  and gross weight is . Originally marketed as the GT. Estimated construction time from the kit is 70 hours and 530 had been completed and flown by 2011.
GT500
Two-seats-in-tandem version powered by a  Rotax 582 two-stroke or a  Rotax 912UL four-stroke. The now out-of-production  Rotax 618 two-stroke was a previously available option. Other options include floats, a ballistic parachute system and crop dusting system. Estimated construction time from the kit is 185 hours and 450 had been completed and flown by 2011. The GT500 is certified in the US primary aircraft category, but only when equipped with the Rotax 582 powerplant.
