Horsepower in the context of Turbine

Trawling is an industrial method of fishing that involves pulling a fishing net through the water behind one or more boats. The net used for trawling is called a trawl. This principle requires netting bags which are towed through water to catch different species of fishes or sometimes targeted species. Trawls are often called towed gear or dragged gear.

The boats that are used for trawling are called trawlers or draggers. Trawlers vary in size from small open boats with as little as 30 hp (22 kW) engines to large factory trawlers with over 10,000 hp (7.5 MW). Trawling can be carried out by one trawler or by two trawlers fishing cooperatively (pair trawling).

Anthony Colin Bruce Chapman CBE RDI (19 May 1928 – 16 December 1982) was an English design engineer, inventor, and builder in the automotive industry, and founder of the sports car company Lotus Cars.

Chapman founded Lotus in 1952 and initially ran Lotus in his spare time, assisted by a group of enthusiasts. His knowledge of the latest aeronautical engineering techniques would prove vital towards achieving the major automotive technical advances for which he is remembered. Chapman's design philosophy focused on cars with light weight and fine handling instead of bulking up on horsepower and spring rates, which he famously summarised as "Adding power makes you faster on the straights. Subtracting weight makes you faster everywhere."

The Rolls-Royce Marine Spey is a marine gas turbine based on the Rolls-Royce Spey and TF41 aircraft turbofan engines. The Marine Spey currently powers seven ship classes including the Royal Navy's Type 23 frigates and provides a power output of 19.5 MW (about 26,150HP). The Marine Spey incorporates technology from the Tay and RB211.

The Nimitz class is a class of ten nuclear-powered aircraft carriers in service with the United States Navy. The lead ship of the class is named after World War II United States Pacific Fleet commander Fleet Admiral Chester W. Nimitz, who was the last living U.S. Navy officer to hold the rank. With an overall length of 1,092 ft (333 m) and a full-load displacement of over 100,000 long tons (100,000 t), the Nimitz-class ships were the largest warships built and in service until USS Gerald R. Ford entered the fleet in 2017.

Instead of the gas turbines or diesel–electric systems used for propulsion on many modern warships, the carriers use two A4W pressurized water reactors. The reactors produce steam to drive steam turbines which drive four propeller shafts and can produce a maximum speed of over 30 knots (56 km/h; 35 mph) and a maximum power of around 260,000 shaft horsepower (190 MW). As a result of nuclear power, the ships are capable of operating for over 20 years without refueling and are predicted to have a service life of over 50 years. They are categorized as nuclear-powered aircraft carriers and are numbered with consecutive hull numbers from CVN-68 to CVN-77.

A fishing trawler is a commercial fishing vessel designed to operate fishing trawls. Trawling is a method of fishing that involves actively dragging or pulling a trawl through the water behind one or more trawlers. Trawls are fishing nets that are pulled along the bottom of the sea or in midwater at a specified depth. A trawler may also operate two or more trawl nets simultaneously (double-rig and multi-rig).

There are many variants of trawling gear. They vary according to local traditions, bottom conditions, and how large and powerful the trawling boats are. A trawling boat can be a small open boat with only 30 horsepower (22 kW) or a large factory ship with 10,000 horsepower (7457 kW). Trawl variants include beam trawls, large-opening midwater trawls, and large bottom trawls, such as "rock hoppers" that are rigged with heavy rubber wheels that let the net crawl over rocky bottom.

The Vought-Sikorsky VS-300 (or S-46) is an American single-engine helicopter designed by Igor Sikorsky. It had a single three-blade rotor originally powered by a 75 horsepower (56 kW) engine. The first "free" flight of the VS-300 was on 13 May 1940. The VS-300 was the first successful single lifting rotor helicopter in the United States and the first successful helicopter to use a single vertical-plane tail rotor configuration for antitorque. With floats attached, it became the first practical amphibious helicopter.

The power band of an internal combustion engine or electric motor is the range of operating speeds under which the engine or motor is able to output the most power, that is, the maximum energy per unit of time. This usually means that maximum acceleration can be achieved inside this band (often at the cost of lower efficiency). While engines and motors have a large range of operating speeds, the power band is usually a much smaller range of engine speed, only half or less of the total engine speed range (electric motors are an exception—see the section on electric motors below).

Specifically, power band is the range of RPM around peak power output. The power band of an internal combustion gasoline automobile engine typically starts at midrange engine speeds (around 4,000 RPM) where maximum torque is produced, and ends below the redline after reaching maximum power (typically between 6,200 RPM and 6,800 RPM). Diesel engines in cars and small trucks may develop maximum torque below 2,000 RPM with the power peak 4,000 RPM or below.

A traction engine is a steam-powered tractor used to move heavy loads on roads, plough ground or to provide power at a chosen location. The name derives from the Latin tractus, meaning 'drawn', since the prime function of any traction engine is to draw a load behind it. They are sometimes called road locomotives to distinguish them from railway locomotives – that is, steam engines that run on rails.

Traction engines tend to be large, robust and powerful, but also heavy, slow, and difficult to manoeuvre. Nevertheless, they revolutionized agriculture and road haulage at a time when the only alternative prime mover was the draught horse.

A performance car is a car that exhibits above-average capabilities in one or more of the following areas: acceleration (torque and throttle response), top speed (horsepower), cornering and braking. It is debated how much performance is required to move classification from standard to high performance.

The Pratt & Whitney Canada PW100 aircraft engine family is a series of 1,800 to 5,000 shaft horsepower (1,300 to 3,700 kW) turboprops manufactured by Pratt & Whitney Canada. Pratt & Whitney Canada dominates the turboprop market with 89% of the turboprop regional airliner installed base in 2016, leading GE Aviation and Allison Engine Company.

The British Mark V tank was an upgraded version of the Mark IV tank.

The tank was improved in several aspects over the Mark IV, chiefly the new steering system, transmission and 150 bhp engine, but it fell short in other areas, particularly its insufficient ventilation, leading to carbon monoxide poisoning for the crew. Various versions were fitted with a variety of armament including 6-pounder guns and machine guns.

A touring motorcycle is a type of motorcycle designed for touring. Although almost any motorcycle can be used for this purpose, manufacturers have developed specific models designed to address the particular needs of these riders. Touring motorcycles commonly have large displacement fairings and windshields that offer a high degree of weather and wind protection, large-capacity fuel tanks for long-distance riding, engines with a great deal of low-end horsepower, and a more relaxed, upright seating position than sport bikes.

Particularly in the US, touring motorcycles may be given names such as bagger, full bagger, full dresser, full dress tourer, or dresser. These monikers (often used disparagingly or jocularly) originally applied to cruisers with full sets of saddlebags or panniers such as Harley-Davidsons; but these terms may now refer to any touring motorcycle.
