British Airship R25
The 23 class were rigid airships produced in the United Kingdom during the First World War. Development of the 23 class began in August 1915 when Vickers was asked to improve the 9r design by increasing its gas capacity by adding a bay and increasing the capacity of the bow and stern gas cells. The 23-class was designed by H.B. Pratt and Barnes Wallis of Vickers. Vickers built the first and last of the four ships. The other two were built by William Beardmore and Company and Armstrong-Whitworth. While the 23 class airships were never used in combat, the four ships provided many hours of valuable training and experimental data for British airship crews and designers. Although a total of 17 of these ships were contemplated at one time, only four were ever built.Higham 1961, pp. 135 The 23 class was found to be significantly overweight, leading to its cancellation in favour of the more-refined R23X class. Design and development Following proposals in July 1915 to order more ...

Rubik R-25 Mokány
The Rubik R-25 Mokány, in en, Plucky person and sometimes known as the R-25 Standard (class), is a Hungarian single seat Standard Class glider of all-metal construction, first flown in 1960. It was one of a series of similar aircraft designed by Ernő Rubik. Only one was built. Design and development In 1957 a team led by Ernő Rubik designed an all-metal glider, the R-23 Gébics, with a pod and boom fuselage, V-tail, fuselage mounted fan airbrakes and corrugated wing skinning. These features were carried forward into a series of gliders that included the R-25 Mokány. This was designed to compete as a Standard Class glider, with a span increased to 15 m (49 ft 5½ in), and introduced a laminar flow NACA 64 series wing profile. Its straight tapered, high cantilever wing has forward sweep on the trailing edge alone. It is built around a single spar with a D-shaped torsion box formed by the corrugated leading section, the ridges running chordw ...

Tumansky R-25
The Tumansky R-25 is a turbojet engine, which is seen as the ultimate development of Tumansky R-11. It was designed under the leadership of Sergei Alekseevich Gavrilov. Design and development The Tumansky R-25 was designed as a replacement for Tumansky R-13 in MiG-21 fighters. R-25 is a two-spool axial-flow turbojet featuring a new compressor with increased overall pressure ratio and airflow, variable two-stage afterburner, and greater use of titanium. The R-25 jet engine's specialty was the addition of a second fuel pump in the afterburning stage. Activating the ЧР (rus. "чрезвычайный режим" - emergency mode) booster feature allows the engine to develop of thrust under of altitude. The limit of operation is 2 minutes in practice and in war, as further use causes the engine to overheat and potentially explode. Use of EPR requires engine take-out inspection upon landing and every minute of its use counts as one full hour of engine runtime on the logbook. Th ...

R25 (London)
R25 was a proposed railway orbital around the Zone 3 area of London, England. First proposed in the Mayor of London's £1.3 trillion London Infrastructure 2050 plan, the line would have used some existing Network Rail and London Overground lines, linked by stretches of new railway. History The R25 nickname alludes to London's M25 orbital motorway. The idea featured in news media when the Mayor of London, Boris Johnson, visited Barking Riverside, a large development held up by lack of rail access in 2014. The idea of extending the Gospel Oak to Barking Line trains onto the Tilbury Loop line The London, Tilbury and Southend line, also known as Essex Thameside, is a commuter railway line on the British railway system. It connects Fenchurch Street station, in central London, with destinations in east London and Essex, including , , ... to serve a station near Barking Riverside had already gained some ground having been mentioned in the 2013 budget statement, but news ...

Toxic If Swallowed
Toxicity is the degree to which a chemical substance or a particular mixture of substances can damage an organism. Toxicity can refer to the effect on a whole organism, such as an animal, bacterium, or plant, as well as the effect on a substructure of the organism, such as a cell (cytotoxicity) or an organ such as the liver ( hepatotoxicity). By extension, the word may be metaphorically used to describe toxic effects on larger and more complex groups, such as the family unit or society at large. Sometimes the word is more or less synonymous with poisoning in everyday usage. A central concept of toxicology is that the effects of a toxicant are dose-dependent; even water can lead to water intoxication when taken in too high a dose, whereas for even a very toxic substance such as snake venom there is a dose below which there is no detectable toxic effect. Toxicity is species-specific, making cross-species analysis problematic. Newer paradigms and metrics are evolvi ...

R-25 Vulkan
The R-25 Vulkan ( sr, Вулкан) was a surface-to-air missile (SAM) designed by Serbian engineer Obrad Vučurović and built in the Socialist Federal Republic of Yugoslavia (SFRY) in the late 1950s, early 1960s. Development The mid-1950s saw the emergence of viable SAMs for the purpose of air defence. Due to their inability to import foreign SAM systems, in 1958 Yugoslavia initiated a program to develop an indigenous missile at the Belgrade Military Technical Institute. Designated the R-25 Vulkan (Volcano), this completely original Yugoslavian design brought together a team of experts led by engineer Obrad Vučurović to design the missile, with the prototypes being made in the SOKO aircraft factory in Mostar. Two versions of the missile were developed: one that had a booster-rocket engine with seven rockets and a second one with four rockets. Although, initial prototypes used a liquid fuel rocket engine developed for a rocket-powered torpedo, later operational production mi ...
