King Khalid Air Base. King Khalid Air Base (Arabic: قاعدة الملك خالد الجوية) (KKAB) is an airbase of Royal Saudi Air Force (RSAF) in the south-west of Saudi Arabia, near Khamis Mushait.

History

The airbase, with code KMX, has a  paved runway without customs facilities. The base was designed and built by the Dutch company Ballast Nedam for BAE in the 1960s, with additional construction through the 1970s and 1980s, and has McDonnell Douglas F-15 Eagle service facilities.

Gulf war

During the Gulf War in 1991, the USAF had a base here from which they launched F-117 stealth fighter from the 37th Tactical Fighter Wing on Baghdad, and other high priority targets in Iraq. On the opening night of the war, Vickers VC10 tankers from No. 101 Squadron RAF launched here refueled Royal Air Force Panavia Tornado GR1s.

The RSAF forces included the newly formed 66th Squadron with Tornado GR1 aircraft and immediately after Gulf war 1 they took delivery of the RSAF GR1a Reconnaissance versions supported by the 66th Squadron Reconnaissance Intelligence Centre (RIC).

Later in the 1990s a second Tornado GR1 Squadron formed -  83rd Squadron.

H-4 Air Base. H-4 Air Base () is a Royal Jordanian Air Force base located near Ruwaished in Mafraq Governorate, Jordan.

Overview
This airfield was built to support the H4 oil pumping station of the Kirkuk–Haifa oil pipeline built by the Iraq Petroleum Company between 1932 and 1934 in the Emirate of Transjordan at that time a protectorate of the British Empire. The airfield was used by the RAF during World War II as the Advanced Headquarters for operations against the rebels in Iraq during the Anglo-Iraqi War. The Airbase is now operated by the Royal Jordanian Air Force.

Between November 2014 and January 2015, the United States began positioning MQ-9 Reaper UAVs at the base.

The base also houses AH-1F Cobras, believed to be from the 10th and 12th Squadrons of the Royal Jordanian Air Force, and a Cessna 208B Caravan from the 15th Squadron and the Air Tractor 802i from the 25th Squadron

C. E. Lipe Machine Shop. The C. E. Lipe Machine Shop was established in Syracuse, New York in 1880 in the Lynch Building by Charles E. Lipe (1850–1895), a mechanical engineer. The building became an early industrial incubator and was commonly known as the Lipe Shop. While Lipe worked on his own ideas, he rented out facilities to others. Some of the leaders in industry worked both independently and side by side in this building to solve the industrial problems of their era. "These men sowed the germs that sprouted into major business enterprises in Syracuse and elsewhere" and for many years the machine shop was known as the "cradle of Syracuse industries."

The building is still in use today as a hardware store.

Davis-Costin Condor. The Davis-Costin Condor was a conventional all-wood, tandem-seat sailplane built in the United Kingdom in the 1950s. Only one was constructed; it was later rebuilt with a longer fuselage and other detailed alterations as the Condor 2.

Design and development

The Condor was an all-wood glider, seating two in tandem. The wing was built around two spars and the planform was unusual in that the chord of the straight tapered inboard section increased outwards.  The outer wing sections, where the ailerons were mounted, were conventionally tapered.  No flaps or airbrakes were fitted.  The wings joined a raised fuselage centre section and were braced by pairs of parallel lift struts from about one third span to the bottom of the fuselage.

Its fuselage was flat sided with angled panels above and below.  The straight edged tailplane and elevators were set well forward on top of the fuselage.  There was no fixed fin, just a generous and slightly angular rudder. The front seat was just ahead of the wing leading edge and the rear one near mid-chord.  A skid from the nose ended under the wing with a small monowheel; a little tailwheel was fixed below the rudder hinge.

The first flight was made in 1953. No Certificate of Airworthiness was issued. Later, P. Davis rebuilt the aircraft with several alterations.  The fuselage was lengthened by 8 in (203 mm), chiefly by moving the cockpit further forward, at the cost of a 7 lb (3.2 kg) increase in weight.  The trailing edge of the rudder was curved outwards and a very small dorsal fillet added.  Minor undercarriage changes were also made. Named Condor 2, the rebuilt aircraft first flew on 13 August 1960.  It was written off less than a year later on 25 June 1961 when it crashed at Chesford Head, near Winchester in Hampshire.

Locale (computer hardware). In computer architecture a locale is an abstraction of the concept of a localized set of hardware resources which are close enough to enjoy uniform memory access.

For instance, on a computer cluster each node may be considered a locale given that there is one instance of the operating system and uniform access to memory for processes running on that node. Similarly, on an SMP system, each node may be defined as a locale. Parallel programming languages such as Chapel have specific constructs for declaring locales.

Chippewa Operating System. The Chippewa Operating System (COS) is a discontinued operating system developed by Control Data Corporation in 1964 for the CDC 6600, generally considered the first supercomputer in the world. The Chippewa was initially developed as an experimental system, but was then also deployed on other CDC 6000 machines. 

The Chippewa was a rather simple job control oriented system derived from the earlier CDC 3000. Its design influenced the later CDC Kronos and SCOPE operating systems. Its name was based on the Chippewa Falls research and development center of CDC in Wisconsin.

It is distinct from and preceded the Cray Operating System (also called "COS") at Cray.

Ginn-Lesniak Kestrel. The Ginn-Lesniak Kestrel is a one-off homebuilt two seat sailplane, designed in the United Kingdom in the 1950s and flown in 1969.

Design and development

Though the sole Kestrel did not fly until 1969, its design and construction began in 1956.  Vic Ginn and Lesniak, both members of the London Gliding Club (LGC) designed it and Ginn built the wings, tailplane and front fuselage at his Luton home.  The rear fuselage was built at the LGC at Dunstable Downs where, after some years delay, the aircraft was finally assembled by Jeff Butt and Ron Dodd.  It was described as a semi-aerobatic aircraft and was built of wood and fabric.

The most unusual feature of the Kestrel is that its straight tapered, cantilever wings have a forward sweep of about 8°.  The wings carry outboard ailerons and airbrakes, the latter at about one third span and chord. There are no flaps. The straight tapered tailplane and elevators, mounted on the upper fuselage, are set forward of the rudder hinge.  The fin and rudder are straight edged and of about equal area, the latter extending to the bottom of the fuselage.

The fuselage has an oval cross section, increasing in depth forwards to behind the cockpit where the wing is mounted.  Both seats, placed in tandem, are forward of the wing root under a canopy.  A skid from  nose to a monowheel below the wing root leading edge forms the undercarriage, assisted by a small tail bumper.

The Kestrel first flew at the  LGC on Dunstable Downs on 19 July 1969.

Operational history
By 1998 the Kestrel, refurbished, was with the Lakes Gliding Club.  By 2010 it had moved to storage with the Anglia Gliding Club at RAF Wattisham.

Robert Ridgway (engineer). Robert Ridgway, sometimes spelled Robert Ridgeway (October 19, 1862 – December 19, 1938), was an American civil engineer.  He did not study engineering at any school, but worked 49 years for New York City in the construction of major projects, and became Chief Engineer of the Transit Commission in 1921.  He became president of the American Society of Civil Engineers (ASCE) Metropolitan section.  Further he became president of the national ASCE in 1925.  The Ridgway Awards are an annual award of the ASCE Met section named for him.

At the time of his death, Ridgway was consulting Secretary of the Interior Harold L. Ickes on Chicago's first subway.  According to the December 20, 1938 edition of the Brooklyn Eagle, he died in Fort Wayne, Indiana after suffering a heart attack, while en route to New York after attending ground-breaking ceremonies for the Chicago Subway.  He was 76.

Works
Major projects he worked on include the New Croton Aqueduct; the first NYC subway line; the first East River subway tunnel; the Catskill Aqueduct, the expansion of the IRT and BMT subways; and the construction of the IND subway.

In 1914, he was serving as Engineer of Subway Construction.  A number of his works are listed on the National Register of Historic Places, with several listed in relation to one multiple property study, the "New York City Subway System MPS".

Works he is credited with include the following subway infrastructure projects:
15th Street–Prospect Park subway station (), 15th Street and Prospect Park West, Brooklyn, NRHP-listed
181st Street subway station (), Fort Washington Avenue, Between West 185th and 181st Streets. Manhattan, NRHP-listed

Griffon Lionheart. The Griffon Lionheart is an American single-engined, six-seat biplane designed and produced in kit form for home building by Griffon Aerospace of Harvest, Alabama.

Design and development
The Lionheart is based on the Beechcraft Staggerwing biplane of the 1930s; but unlike the steel tube, wood and fabric construction of the Staggerwing it has a composite structure.  The Staggerwing has strut-braced wings but the Lionheart has cantilever wings with a total area about 20% less than the wings of the Staggerwing. It is powered by a 450 hp (336 kW) Pratt & Whitney R-985 Wasp Junior radial engine with a three-bladed propeller. It has a retractable conventional landing gear with a tailwheel. The enclosed cabin is slightly longer than the Staggerwing's cabin to allow room for the pilot and five passengers, and it has a split airstair access door on the port side.

The Lionheart first flew on 27 July 1997 and was first displayed in public at EAA AirVenture Oshkosh a few days later. Five kits were sold by April 1998, and two of the kits were completed by 2001, with another almost complete. As of August 2011, three Lionhearts are registered in the United States, with another example on display in an aviation museum at Tullahoma Regional Airport in Tullahoma, Tennessee. Kits are no longer being produced.

Dredge drag head. A dredge drag head is used by a trailing suction hopper dredger to collect sand from the sea floor.

The dredge drag head is a steel structure that is connected to the dredger by a suction pipe. Supported by the gantries and by using hydraulic winches the dredge drag head and suction pipe are let down onto the sea bottom in order to suck a mixture of water and sand.

In order to dredge in waves, the suction pipe is suspended from special davits, which operate with heave compensation to ensure that the drag head nozzles stay in contact with the sea bed. The control of mixture of water and sand is done by a so-called dredge drag head visor. The visor controls the amount of water that enters along with the sand. In some cases this visor is hydraulically controlled.

To cut the sea bed, the dredge drag head is equipped with replaceable teeth and water jet nozzles. The nozzles are placed at the front of the dredge drag head and used to cut the sand at the sea bed vertically, while the replaceable teeth are placed at the back to cut horizontally.

Haufe HA-G-1 Buggie. The Haufe HA-G-1 Buggie is an American high-wing, strut-braced, single-seat, glider that was designed and constructed by Bruno Haufe and Klaus Hill, first flying in 1967.

Design and development
Haufe and Hill intended to design and build a glider in the style of the classic open-cockpit gliders of the 1930s, like the Hütter Hü 17. The resulting design was an all-metal aircraft, with a welded steel tube fuselage, covered in doped aircraft fabric covering. The  span wing has an 11.2:1 aspect ratio, employs a Clark Y airfoil and mounts spoilers. The landing gear is a fixed monowheel, supplemented by a fixed skid. The prototype was painted a bright yellow.

Only one Buggie was completed; the aircraft was registered with the US Federal Aviation Administration in the Experimental - Amateur-built category.

Haufe and Hill went on to design and built the Haufe HA-S-2 Hobby and the Haufe HA-S-3 Hobby, based on their experiences with the Buggie.

Operational history
In August 2011 the sole example built was still on the FAA registry, although its status was listed as "in question".

Goair Trainer. 

The Goair Trainer is an Australian single-engined, two-seat, training or touring cabin monoplane designed and built by Goair Products at Bankstown Airport in Sydney, Australia.

Design and development
The Trainer is a low-wing monoplane, first flown in July 1995 and powered by a 118 hp (88 kW) Lycoming O-235 piston engine driving a two-bladed propeller. It has a fixed tricycle landing gear and an enclosed cockpit for two in side-by-side configuration with a sliding canopy for access.

Flight testing was completed in November 1998; following this a second substantially-modified aircraft was built as the GoAir GT-1 Trainer, using the engine and instruments from the first aircraft. Changes included a wider fuselage and different ailerons and flaps; the GT-1 was eventually developed into the Brumby Aircraft Brumby 600.

D-Motor LF26. The D-Motor LF26 is a lightweight liquid cooled side-valve four-stroke flat four, 2.7 litre petrol aircraft engine, produced by D-Motor in Deerlijk, Belgium.

Design and development
This direct-drive aero-engine is unusual in two respects: it is very oversquare with a bore:stroke ratio of 1.295:1, and it has a side-valve (flathead) valvetrain.  The designer determined that since maximum continuous power output (65.3 kW) was to be developed at only 2800 rpm, the extra weight and complexity of overhead valves (OHV) would be superfluous. The resulting engine is compact and lightweight, with a dry weight of , and a maximum power-to-weight ratio of 1.09 kW/kg (wet; coolant fluids weigh ). The engine has port injection, a dry sump lubrication system, and dual ignition.

Variants
With the aid of funding from the Belgian government, D-Motor has developed a derivative 4-litre flat-six engine, the D-Motor LF39, which is claimed to produce  and to have dry weight of .

Peterson MAP-3 Medena. The Peterson MAP-3 Medena is an American shoulder-wing, single-seat, FAI Open Class glider that was designed and constructed by Max A. Peterson, first flying in 1966.

Design and development
Peterson completed the Medena prototype and flew it in 1966. The designation indicates the designer's initials.

The aircraft is of mixed construction, with an all-metal structure and a fiberglass cockpit section. The  span wings employ a NACA 64(3)-618 airfoil and mount both spoilers and half-span flaps. The flaps can be raised 5° for cruise flight and deployed to 60° for glidepath control on landing. The landing gear is a retractable monowheel.

Only one Medena was constructed.

Operational history
The prototype's wings and tail were damaged in a wind storm in 1967 and the aircraft was rebuilt to incorporate modifications to the tail and aft fuselage. Peterson sold the Medana to Joe Gray in 1971. Ownership transferred to Sam Phillips in May 1975.  Ownership transferred to Donald Young/Oren Irich in May 1978. In August 2011 the aircraft was still on the US Federal Aviation Administration registry, although the agency listed its status as "in question"
