What are some mechanical properties of pykrete

Admiral of the Fleet Louis Francis Albert Victor Nicholas Mountbatten, 1st Earl Mountbatten of Burma, was a British Royal Navy officer and statesman, an uncle of Prince Philip, Duke of Edinburgh, and second cousin once removed of Queen Elizabeth II. During the Second World War, he was Supreme Allied Commander, South East Asia Command (1943–1946). He was the last Viceroy of India (1947) and the first Governor-General of independent India (1947–1948).

Max Ferdinand Perutz was an Austrian-born British molecular biologist, who shared the 1962 Nobel Prize for Chemistry with John Kendrew, for their studies of the structures of haemoglobin and myoglobin. He went on to win the Royal Medal of the Royal Society in 1971 and the Copley Medal in 1979. At Cambridge he founded and chaired (1962–79) The Medical Research Council (MRC) Laboratory of Molecular Biology (LMB), fourteen of whose scientists have won Nobel Prizes. Perutz's contributions to molecular biology in Cambridge are documented in The History of the University of Cambridge: Volume 4 published by the Cambridge University Press in 1992.

Fiber is a natural or synthetic substance that is significantly longer than it is wide. Fibers are often used in the manufacture of other materials. The strongest engineering materials often incorporate fibers, for example carbon fiber and ultra-high-molecular-weight polyethylene.

Smithfield is a district in the City of London, located in Central London, England. The principal street of the area is West Smithfield.

The Hughes H-4 Hercules is a prototype strategic airlift flying boat designed and built by the Hughes Aircraft Company. Intended as a transatlantic flight transport for use during World War II, it was not completed in time to be used in the war. The aircraft made only one brief flight on November 2, 1947, and the project never advanced beyond the single example produced.

A runabout is any small motorboat holding between four and eight people, well suited to moving about on the water. Characteristically 20' to 35' but under 35', runabouts are used for pleasure activities like boating, fishing, and water skiing, as a ship's tender for larger vessels, or in racing. Some common runabout types are bow rider, center console, cuddy boat and walkaround.

Paperboard is a thick paper-based material. While there is no rigid differentiation between paper and paperboard, paperboard is generally thicker than paper and has certain superior attributes such as foldability and rigidity. According to ISO standards, paperboard is a paper with a grammage above 250 g/m2, but there are exceptions. Paperboard can be single- or multi-ply.

Project Habakkuk or Habbakuk was a plan by the British during the Second World War to construct an aircraft carrier out of pykrete for use against German U-boats in the mid-Atlantic, which were beyond the flight range of land-based planes at that time. The idea came from Geoffrey Pyke, who worked for Combined Operations Headquarters. After promising scale tests and the creation of a prototype on a lake in Alberta, Canada, the project was shelved due to rising costs, added requirements, and the availability of longer-range aircraft and escort carriers which closed the Mid-Atlantic gap the project was intended to address.

Papier-mâché is a composite material consisting of paper pieces or pulp, sometimes reinforced with textiles, bound with an adhesive, such as glue, starch, or wallpaper paste.

Geoffrey Nathaniel Joseph Pyke was an English journalist, educationalist, and later an inventor whose clever, but unorthodox, ideas could be difficult to implement.

The Yakovlev Yak-44 was a proposed twin-turboprop Airborne Early Warning (AEW) aircraft, resembling the United States Navy's E-2 Hawkeye, intended for use with the Soviet Navy's Ulyanovsk class supercarriers. Along with the aircraft carrier it would have flown from, the Yak-44 was cancelled after the demise of the Soviet Union. A full-scale mockup with foldable wings was built.

An arresting gear, or arrestor gear, is a mechanical system used to rapidly decelerate an aircraft as it lands. Arresting gear on aircraft carriers is an essential component of naval aviation, and it is most commonly used on CATOBAR and STOBAR aircraft carriers. Similar systems are also found at land-based airfields for expeditionary or emergency use. Typical systems consist of several steel wire ropes laid across the aircraft landing area, designed to be caught by an aircraft's tailhook. During a normal arrestment, the tailhook engages the wire and the aircraft's kinetic energy is transferred to hydraulic damping systems attached below the carrier deck. There are other related systems which use nets to catch aircraft wings or landing gear. These barricade and barrier systems are only used for emergency arrestments for aircraft without operable tailhooks.

A screw-propelled vehicle is a land or Amphibious Vehicle designed to cope with difficult snow and ice or mud and swamp. Such vehicles are distinguished by being moved by the rotation of one or more auger-like cylinders fitted with a helical flange that engages with the medium through or over which the vehicle is moving. Modern vehicles called Amphirols and other similar vehicles have specialised uses.

An ice pop is a water or milk-based quiescently frozen snack on a stick. Unlike ice cream or sorbet, which are whipped while freezing to prevent ice crystal formation, an ice pop is frozen while at rest and becomes a solid block of ice. The stick is used as a handle to hold it. Without a stick, the frozen product is known as something else.

The Short Mayo Composite was a piggy-back long-range seaplane/flying boat combination produced by Short Brothers to provide a reliable long-range air transport service to North America and, potentially, to other distant places in the British Empire and the Commonwealth.

Herman Francis Mark was an Austrian-American chemist regarded for his contributions to the development of polymer science. Mark's x-ray diffraction work on the molecular structure of fibers provided important evidence for the macromolecular theory of polymer structure. Together with Houwink he formulated an equation, now called the Mark–Houwink or Mark–Houwink–Sakurada equation, describing the dependence of the intrinsic viscosity of a polymer on its relative molecular mass. He was a long-time faculty at Polytechnic Institute of Brooklyn. In 1946, he established the Journal of Polymer Science.

The Malting House School was an experimental educational institution that operated from 1924 to 1929. It was set up by the eccentric and, at the time, wealthy Geoffrey Pyke in his family home in Cambridge and it was run by Susan Sutherland Isaacs. Although it was open for only a few years, the radical ideas explored in this institution have remained influential up until the present day. It is now owned by Darwin College, Cambridge where it is used as accommodation.

The cast of the television series MythBusters perform experiments to verify or debunk urban legends, old wives' tales, and the like. This is a list of the various myths tested on the show as well as the results of the experiments.

Patricia Lake is a lake in Jasper National Park, Alberta, Canada, near the town of Jasper. It was named for Princess Patricia of Connaught, a granddaughter of Queen Victoria.

Lily and Clover were two experimental floating airfields tested towards the end of the Second World War by the British Admiralty.
