The Albatros L 57 was an early monoplane. It was a project for an airliner but was never completed, and as such never entered production. The top covering of the fuselage is swept up higher as compared to other similar planes of the era. The plane was designed to have up to six passengers.
A luge is a small one- or two-person sled on which one sleds supine (face-up) and feet-first. A luger begins seated, propelling themselves initially from handles on either side of the start ramp, then steers by using the calf muscles to flex the sled's runners or by exerting opposite shoulder pressure to the pod. Racing sleds weigh 21–25 kg (46–55 lb) for singles and 25–30 kg (55–66 lb) for doubles. Luge is also the name of an Olympic sport that employs that sled and technique.
The DFS 346 was a German rocket-powered swept-wing aircraft which began development during World War II in Germany. It was designed by Felix Kracht at the Deutsche Forschungsanstalt für Segelflug (DFS), the "German Institute for Sailplane Flight". A prototype was constructed but did not reach completion before the end of the war. It was taken to the Soviet Union where it was completed, tested and flown.
In aviation, airspeed is the speed of an aircraft relative to the air. Among the common conventions for qualifying airspeed are:
The Blohm & Voss Ha 139 was a German all-metal inverted gull wing floatplane. With its four engines it was at the time one of the largest float-equipped seaplanes that had been built. The inboard engines were mounted at the joint between the inboard anhedral and outboard dihedral wing sections, above the pylon-mounted floats.
The Sikorsky Cypher and Cypher II are types of unmanned aerial vehicles developed by Sikorsky Aircraft. They are vertical takeoff and landing aircraft which use two opposing rotors enclosed in a circular shroud for propulsion.
The AeroVironment RQ-14 Dragon Eye is a small reconnaissance miniature UAV developed by the Naval Research Laboratory and the Marine Corps Warfighting Laboratory for use by the United States Marine Corps.
The Scorpio is a brand of underwater submersible Remotely Operated Vehicle (ROV) manufactured by Perry Tritech used by sub-sea industries such as the oil industry for general operations, and by the Royal Navy and the United States Navy for submarine rescue services. Originally developed by AMETEK Straza of El Cajon, United States, they were subsequently developed by Perry Tritech. Although the design of the original Scorpio is over several decades old, it forms the basis for a current generation of Scorpio-branded ROVs. Scorpio ROVs are named in a sequence following the order of manufacture, such as "Scorpio 17" or "Scorpio 45" which refer to specific ROVs.
The Lancair IV and IV-P are a family of four-seat, low-wing, retractable-gear, composite monoplanes powered by a 550 cubic inch Continental TSIO-550 twin-turbocharged piston engine.
Dante Alighieri was the first dreadnought battleship built for the Regia Marina and was completed in 1913. The ship served as a flagship during World War I, but saw very little action other than the Second Battle of Durazzo in 1918 during which she did not engage enemy forces. She never fired her guns in anger during her career. Dante Alighieri was refitted in 1923, stricken from the Navy List five years later and subsequently sold for scrap.
The Storozhevoyclass were a group of 18 destroyers built for the Soviet Navy in the late 1930s that were officially known as Project 7U. The design was finalised in 1936 after initial disappointments with the Gnevny class. The main changes were unit machinery, a strengthened hull and reduced fuel capacity. The anti-aircraft guns were repositioned to improve firing arcs. The ships fought in World War II.
In common usage, the mass of an object is often referred to as its weight, though these are in fact different concepts and quantities. Nevertheless, one object will always weigh more than another with less mass if both are subject to the same gravity.
The SIAI-Marchetti SM.1019 is an Italian STOL liaison monoplane built by SIAI-Marchetti for the Italian Army. It is a turboprop-powered derivative of the Cessna O-1 Bird Dog.
The PZL M-17 "Duduś Kudłacz" was a Polish twin-boom pusher general aviation and trainer aircraft of 1977, which remained a prototype.
The Heinkel He 64 was a sports plane built in Germany in 1933 to participate in the touring plane championships that year, designed by Siegfried and Walter Günter.
The Esse 990 is a 9.9 meter long racing sportboat designed by Umberto Felci and built by Josef Schuchter Sportboats of Stafa, Switzerland. The first hull was sold in 2008 and series production was begun in 2009.
Sea Dragon-class remotely operated underwater vehicles (ROUVs) are a class of Chinese remotely operated vehicle (ROV) used to perform various underwater tasks such as oil platform service, salvage, and rescue missions. Following the successful development of the original Sea Dragon (海龙), a series of ROUVs based on it have been developed. The original model had a diving capability up to 3,500 meters, but subsequent models were designed to meet a variety of operating conditions.
RWD 22 was a Polish twin-engine torpedo bomber and naval reconnaissance floatplane design. Developed by Leszek Dulęba and Andrzej Anczutin of Doświadczalne Warsztaty Lotnicze in 1939, the project was to be developed under the brand of the RWD design bureau. The outbreak of World War II interrupted the design and it never left the planning stage.
The UTVA Kobac was a prototype Serbian single-engine, low-wing tandem-seat turboprop training/light attack aircraft manufactured by Pančevo based UTVA Aviation Industry, and designed by the Military Technical Institute. Revealed as a mockup on 02 September 2012 during the Batajnica 2012 Air Show, the aircraft's first flight was planned for 2013, but was never realized.
Dirgantara Air Service Flight 3130 (DIR3130/AW3130) was a scheduled domestic passenger flight operated by Dirgantara Air Service from Datah Dawai Airport, Malinau Regency, East Kalimantan to its provincial capital's airport, Samarinda Temindung Airport, Samarinda, East Kalimantan. On 18 November 2000, the aircraft conducting the flight, a Britten Norman Islander BN-2 sheared tree tops and crashed onto the forest near the airport shortly after takeoff.
