D. M. Cornish

David M. Cornish (born 1972) is a fantasy author and illustrator from Adelaide, South Australia. His first book is Foundling, the first part of the Monster Blood Tattoo trilogy. The second book named Lamplighter was released in May 2008. The third in the series is named Factotum and was released in October 2010. He has stated that he plans to continue writing novels set in the Half-Continent and in March 2014, published a book of short stories titled Tales from the Half-Continent (Monster Blood Tattoo 3.5).

Cornish studied illustration at the University of South Australia, where in 1993 he began to compile a series of notebooks: over the next ten years he filled 23 journals with his pictures, definitions, ideas and histories of his world, the "Half-Continent".

It was not until 2003 that a chance encounter with a children's publisher gave him an opportunity to develop these ideas further. Learning of his journals, she urged him to write a story from his world. Cornish was sent away with the task of delivering 1,000 words the following week and each week thereafter. Abandoning all other paid work, he spent the next two years propped up with one small advance after another.

Dèmè

Dèmè is a small town and arrondissement located in the commune of Adjohoun in the Borgou Department of Benin. Agriculture is the main industry lying in the fertile Ouémé River Valley of southern Benin. In 2008 during the 2008 Benin floods, the area was affected by the flooding of the Ouémé River which affected much of Adjohoun commune.

Anglo-Saxon law

Anglo-Saxon law (Old English ǣ, later lagu "law"; dōm "decree, judgement") is a body of written rules and customs that were in place during the Anglo-Saxon period in England, before the Norman conquest. This body of law, along with early Scandinavian law and Germanic law, descended from a family of ancient Germanic custom and legal thought. However, Anglo-Saxon law codes are distinct from other early Germanic legal statements - known as the leges barbarorum - in part because they were written in Anglo-Saxon, instead of in Latin. The laws of the Anglo-Saxons were the second in medieval Western Europe after those of the Irish to be expressed in a language other than Latin.

Overview

S1.5400

The S1.5400 (GRAU Index 11D33) was a Soviet single nozzle liquid propellant rocket engine burning liquid oxygen and kerosene in an oxidizer rich staged combustion cycle. It was the first rocket engine to use this cycle in the world, and it was designed by V. M. Melnikov, an alumnus of Isaev, within Korolev's Bureau, for the Molniya fourth stage, the Block-L. It was also the first Soviet engine designed for start and restart in vacuum, and had the highest isp at the time of its deployment.

Its development took from 1958 to 1960. The first production run was started on May 1960, and it passed all the firing tests. Its first flight failed before the Block-L was activated and it was in a Venera flight during 1961 that it had its first success. Between 1961 and 1964 it went through an improvement program that ended up in the S1.5400A1 version (GRAU Index 11D33M). It improved thrust from 63.74 kilonewtons (14,330 lbf) to 66.69 kilonewtons (14,990 lbf) and isp from 338.5s to 340s, while keeping weight the same.

RD-253

The RD-253 (Russian: Раке́тный дви́гатель 253, Rocket Engine 253) and its later variants, the RD-275 and RD-275M, are liquid-propellant rocket engines developed in the Soviet Union by Energomash. The engines are used on the first stage of the Proton launch vehicle and use an oxidizer-rich staged combustion cycle to power the turbopumps. The engine burns UDMH/N₂O₄, which are highly toxic but hypergolic and storable at room temperature, simplifying the design.

History

Development of RD-253 started in 1961. Preliminary investigations and development of the engine as well as its further production was performed under the guidance of Valentin Glushko and finished in 1963. The RD-253 uses a staged combustion cycle for oxidizer-rich generator gas. It was used for the first time in July 1965 year when six engines powered the first stage of the rocket. Development and production of RD-253 was a qualitative leap forward for rocketry of that time by achieving high levels of thrust, specific impulse and pressure in the combustion chamber. This engine is one of the most reliable engines in the USSR and modern Russia.

11D428

The 11D428A-16 (manufacturer's name RDMT-135M) is a liquid pressure-fed rocket engine burning N₂O₄/UDMH with an O/F of 1.85. It is used for crew-rated spacecraft propulsion applications. It is currently used in the KTDU-80 spacecraft propulsion module. The previous version, the 11D428A (manufacturer's name RDMT-135) is still used as the reaction control system thrusters of the Zvezda ISS module. The 11D428A-16 generates 129.16 N (29.04 lbf) of thrust with a chamber pressure of 0.88 MPa (128 psi) and achieves a specific impulse of 291 s (2.85 km/s). It is rated for 500,000 starts with a certified ignition time of 0.03 seconds to 2000 seconds. Each unit weights 1.5 kg (3.3 lb).

Versions

This engine has been used with certain variations in manned Russian space program since the Salyut 6 in Soviet times. The three main versions are:
