List Of Rolls-Royce Merlin Variants
This is a list of Rolls-Royce Merlin variants. Engines of a similar power output were typically assigned different model numbers based on supercharger or propeller gear ratios, differences in cooling system or carburettors, engine block construction, starting system, or arrangement of engine controls. All Merlin engines were "right hand tractor", ''i.e.'' the propeller rotated clockwise viewed from behind, unless otherwise noted. Variant table References Notes Bibliography *Air Ministry.

Sea Hurricane Mk
The sea, connected as the world ocean or simply the ocean, is the body of salty water that covers approximately 71% of the Earth's surface. The word sea is also used to denote second-order sections of the sea, such as the Mediterranean Sea, as well as certain large, entirely landlocked, saltwater lakes, such as the Caspian Sea. The sea moderates Earth's climate and has important roles in the water, carbon, and nitrogen cycles. Humans harnessing and studying the sea have been recorded since ancient times, and evidenced well into prehistory, while its modern scientific study is called oceanography. The most abundant solid dissolved in seawater is sodium chloride. The water also contains salts of magnesium, calcium, potassium, and mercury, amongst many other elements, some in minute concentrations. Salinity varies widely, being lower near the surface and the mouths of large rivers and higher in the depths of the ocean; however, the relative proportions of dissolved ...

Beaufighter Mk
The Bristol Type 156 Beaufighter (often called the Beau) is a British multi-role aircraft developed during the Second World War by the Bristol Aeroplane Company. It was originally conceived as a heavy fighter variant of the Bristol Beaufort torpedo bomber. The Beaufighter proved to be an effective night fighter, which came into service with the Royal Air Force (RAF) during the Battle of Britain, its large size allowing it to carry heavy armament and early airborne interception radar without major performance penalties. The Beaufighter was used in many roles; receiving the nicknames ''Rockbeau'' for its use as a rocket-armed ground attack aircraft and ''Torbeau'' as a torpedo bomber against Axis shipping, in which it replaced the Beaufort. In later operations, it served mainly as a maritime strike/ground attack aircraft, RAF Coastal Command having operated the largest number of Beaufighters amongst all other commands at one point.

100 Octane
An octane rating, or octane number, is a standard measure of a fuel's ability to withstand compression in an internal combustion engine without detonating. The higher the octane number, the more compression the fuel can withstand before detonating. Octane rating does not relate directly to the power output or the energy content of the fuel per unit mass or volume, but simply indicates gasoline's capability against compression. Whether or not a higher octane fuel improves or impairs an engine's performance depends on the design of the engine. In broad terms, fuels with a higher octane rating are used in higher-compression gasoline engines, which may yield higher power for these engines. Such higher power comes from the fuel's higher compression by the engine design, and not directly from the gasoline. In contrast, fuels with lower octane (but higher cetane numbers) are ideal for diesel engines because diesel engines (also called compression-ignition engines) do not compress the fuel ...

Coffman Engine Starter
The Coffman engine starter (also known as a "shotgun starter") was a starting system used on many piston engines in aircraft and armored vehicles of the 1930s and 1940s. It used a cordite cartridge to move a piston, which cranked the engine. The Coffman system was one of the most common brands; another was the Breeze cartridge system, which was produced under Coffman patents. Most American military aircraft and tanks which used radial engines were equipped with this system. Some versions of the Rolls-Royce Merlin engine used in the British Supermarine Spitfire used the Coffman system as a starter. The Hawker Typhoon and Hawker Tempest also used the Coffman system to start their Napier Sabre engines. Cartridge starters used on a number of jet engines, including such engines as the Rolls-Royce Avon, which were used in the English Electric Canberra and Hawker Hunter aircraft, used a high gas volume cartridge driving a turbine instead of a piston. Some Snowcat and similar vehicles use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Wellington Mk
Wellington ( mi, Te Whanganui-a-Tara or ) is the capital city of New Zealand. It is located at the south-western tip of the North Island, between Cook Strait and the Remutaka Range. Wellington is the second-largest city in New Zealand by metro area, and is the administrative centre of the Wellington Region. It is the world's southernmost capital of a sovereign state. Wellington features a temperate maritime climate, and is the world's windiest city by average wind speed. Legends recount that Kupe discovered and explored the region in about the 10th century, with initial settlement by Māori iwi such as Rangitāne and Muaūpoko. The disruptions of the Musket Wars led to them being overwhelmed by northern iwi such as Te Āti Awa by the early 19th century. Wellington's current form was originally designed by Captain William Mein Smith, the first Surveyor General for Edward Wakefield's New Zealand Company, in 1840. The Wellington urban area, which only includes ur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fulmar Mk
The fulmars are tubenosed seabirds of the family Procellariidae. The family consists of two extant species and two extinct fossil species from the Miocene. Fulmars superficially resemble gulls, but are readily distinguished by their flight on stiff wings, and their tube noses. They breed on cliffs, laying one or rarely two eggs on a ledge of bare rock or on a grassy cliff. Outside the breeding season, they are pelagic, feeding on fish, squid and shrimp in the open ocean. They are long-lived for birds, living for up to 40 years. Historically, the northern fulmar lived on the Isle of St Kilda, where it was extensively hunted. The species has expanded its breeding range southwards to the coasts of England and northern France. Taxonomy The genus ''Fulmarus'' was introduced in 1826 by the English naturalist James Stephens. The name comes from the Old Norse ''Fúlmár'' meaning "foul-mew" or "foul-gull" because of the birds' habit of ejecting a foul-smelling oil. The type s ...

Rotol
Dowty Propellers is a British engineering company based in Brockworth, Gloucestershire that specialises in the manufacture, repair and overhaul of propellers and propeller components for customers around the world. It is owned by General Electric, forming part of its GE Aviation Systems division. History The company was formed as Rotol Airscrews in 1937 by Rolls-Royce and Bristol Engines to take over both companies' propeller development, the market being too small to support more than one company. The name is a contraction of "ROlls-Royce" and "BrisTOL". Rotol's propellers were always considered leading edge, its models equipping the Hawker Hurricane, Supermarine Spitfire, and many other Second World War-era aircraft. By the end of the war it had introduced the first five-bladed propeller to see widespread use, used on late-model Spitfires. In 1943 the company changed its name from Rotol Airscrews Limited to Rotol Limited, and in 1952 it acquired British Messier Limited, a ...
