39-527: One-make racing series (also known as spec racing series) are racing series in which all competitors race with identical or very similar vehicles from the same manufacturer and suppliers. Typically, this means the same type of chassis, powertrain , tyres, brakes, and fuel are used by all drivers. The idea behind one-make car racing is that success will be based more on driver skill and car setup , instead of engineering skill and budget. One-make series are popular at an amateur level as they are affordable, due to

78-662: A development class , the classic example being America's Cup 12-metre class , or to the box rule used, for example, in the TP 52 class. A further category, the formula based class setup, is sometimes confused with one design. The Mini Transat 6.50 , the Volvo Open 70 monohull, the large ORMA trimaran, and the Formula 18 racing beach catamaran are the exponents of the formula approach. Class-legal boats race each other without any handicap calculations in both setups. However, under one design

117-436: A racing class that consists of just one model or design of a sailboat . In one-design racing, the first boat to finish wins the race. This is contrasted with handicap racing, where time is added or subtracted from the finishing times based on design factors and mathematical formulas to determine the winner. In between One-design and handicap racing, a number of other approaches exist. One-design classes can be contrasted with

156-406: A cost basis for determining the total economic value of an investment. Examples include: return on investment , internal rate of return , economic value added , return on information technology, and rapid economic justification. A TCO analysis includes total cost of acquisition and operating costs , as well as costs related to replacement or upgrades at the end of the life cycle. A TCO analysis

195-461: A general rule, the tolerances are strictest in smaller boats like dinghy classes and small keelboats. In some cases the tolerances are specified in a confidential Building Specification and often everything is designed and produced at the same factory or a very few factories. Examples are the Laser , Melges 24 , and several small keelboats designed by Nathanael Greene Herreshoff, such as the 12½ . In others

234-510: A lifting boiler plate capable of being lifted. The boat was called The Water Wag . The idea was quickly adopted by sailors in Ireland, England, India and South America. The Water Wag Club still thrives in Dun Laoghaire, Co. Dublin. The Solent One Design Class was one of the earliest one-design classes formed after discussions took place in 1893 and subsequent years. It quickly became popular, and

273-410: A variety of critical requirements and costs over the life of the building: A key objective of planning, constructing, operating, and managing buildings via TCO principals is for building owners and facility professionals to predict needs and deliver data-driven results.  TCO can be applied any time during the life of a facility asset to manage cost inputs for the life of the structure or system into

312-595: Is achieved through metrology technology applied to all of the steps in powertrain manufacturing processes. In automotive manufacturing, the frame plus the "running gear" makes the chassis . Later, a body (sometimes referred to as " coachwork "), which is usually not necessary for integrity of the structure, is built on the chassis to complete the vehicle . Commercial vehicle manufacturers may have "chassis only" and "cowl and chassis" versions that can be outfitted with specialized bodies. These include buses , motor homes , fire engines , ambulances , etc. The frame plus

351-473: Is easily applicable to the transportation industry and to motor vehicle ownership, for example, the TCO defines the cost of owning an automobile from the time of purchase by the owner, through its operation and maintenance to the time it leaves the possession of the owner. Comparative TCO studies between various models help consumers choose a car to fit their needs and budget. Some of the key elements incorporated in

390-733: Is important to industry, including the automotive and other vehicle sectors. Competitiveness drives companies to engineer and produce powertrain systems that over time are more economical to manufacture, higher in product quality and reliability, higher in performance, more fuel efficient, less polluting, and longer in life expectancy. In turn these requirements have led to designs involving higher internal pressures, greater instantaneous forces, and increased complexity of design and mechanical operation. The resulting designs in turn impose significantly more severe requirements on parts shape and dimension; and material surface flatness , waviness , roughness , and porosity . Quality control over these parameters

429-525: Is used to gauge the viability of any capital investment . An enterprise may use it as a product/process comparison tool. It is also used by credit markets and financing agencies. TCO directly relates to an enterprise's asset and/or related systems total costs across all projects and processes, thus giving a picture of the profitability over time. TCO analysis was popularized by the Gartner Group in 1987. The roots of this concept date at least back to

468-555: Is usually shown by his final standing in a contest. What could be more indicative of this when pilots are flying identical sailplanes with identical performance. One-design competition is the sure test of soaring skill." Other one-design gliders have included those made in Russia by Aviastroitel , in Poland by Warsztaty Szybowcowe Orlik , and Germany, where for example the DFS Olympia Meise

507-634: The British Rail Class 03 and British Rail Class 04 diesel shunting locomotives. This section uses infographics to show a unified model with variations, the green wheels denote no traction, and the angled wheels denote steering. 6X4 means 6 wheel ends and 4 positions distribute power (power divider installed) 6X2 means 6 wheel ends and 2 positions distribute power (single axle drive) 4X0 means 4 wheel ends no power (Trailer axle) 4x2 means 4 Wheel ends, 2 Positions to distribute power The 6 wheel ends can either be wide base singles or duals. Its about

546-567: The W Series . The Formula One race series are not one-design nor one-make racing series as they allow participation by different manufacturers, each designing their own chassis and powertrain (within limits set by ' the formula '). Some spec parts are mandated, such as tyres and sensors. NASCAR is much in the same boat, with three distinct bodies (Chevrolet, Ford and Toyota) and four distinct engines ( Hendrick , ECR , Roush Yates , TRD ) available in competition. Additionally, while IndyCar cars are all virtually identical Dallara DW12 models,

585-509: The prime mover , that changes depending on whether a vehicle is front-wheel , rear-wheel , or four-wheel drive , or less-common six-wheel or eight-wheel drive . In a wider sense, the powertrain includes all of the components used to transform stored (chemical, solar, nuclear, kinetic, potential, etc.) energy into kinetic energy for propulsion purposes. This includes the utilization of multiple power-sources and non–wheel-based vehicles. The most recent developments in powertrain are driven by

624-544: The 1970s with the introduction of laminate construction using fibre-reinforced plastic (FRP) and mold building technology. This process allowed the mass production of identical hulls of virtually any size at a lower price. The one-design design idea was created by Thomas Middleton of the Shankill Corinthian Club located 10 miles (16 km) south of Dublin, Ireland in 1887. He proposed a class of double ended open dinghies of simple clincher construction in pine with

663-511: The 20+ approved builders on four continents being of identical speed, for example at the 2017 World Championship. In medium- to large-sized boat classes, One design would refer to conformance to a standard specification , with the possibility of alterations being allowed as long as they remained within certain tolerances. Examples of this are the Dragon , J/24 , Etchells , H-boat and the Farr 40 . After

702-732: The National Register of Historic Vessels of the United Kingdom. She is kept in Lymington where she is still racing and winning on the Solent. Conversely the Howth 17 , designed just four years later by Sir Walter H. Boyd of Howth , Co. Dublin is still actively raced and is the oldest one-design racing keelboat still sailing as designed. While fifteen of the current fleet were built from 1898 to 1914, new boats can still be added, most recently in 2017. As

741-620: The advantages of one-design to the sport of competitive glider racing . The most successful of these has been the Schweizer 1–26 class with 700 aircraft completed and flown between 1954 and 1981. Schweizer Aircraft principal Paul A Schweizer was a proponent of the One-design concept. He intended the company's 1–26 to be the aircraft to establish a one-design class in the United States. He wrote: "The true measure of pilot ability and experience

780-482: The boats are virtually identical except in details. At the same time, the formula setup allows the boats to differ much more in design while keeping a few important specifications the same. As a result, the identifier "One design" has been used more and more exclusively to denote a class that races only identical boats. Having a rigid one-design specification keeps design experimentation to a minimum and reduces cost of ownership . The popularity of one-design increased in

819-492: The body makes a glider (a vehicle without a powertrain). The final drive is the last in the set of components which delivers torque to the drive wheels . In a road vehicle, it incorporates the differential . In a railway vehicle, it sometimes incorporates the reversing gear. Examples include the Self-Changing Gears RF 28 (used in many first-generation diesel multiple units of British Railways ) and RF 11 used in

858-433: The electrification of it in multiple components. Electrical energy needs to be provided, usually this leads to larger batteries. Electric motors can be found as isolated component or as part of other elements, e.g. the axle . In hybrid powertrains the torque generated by the combustion engine and the electric motor have to be brought together and distributed to the wheels. The control of this process can be quite involved but

897-419: The first quarter of the twentieth century. Many different methodologies and software tools have been developed to analyze TCO in various operational contexts. TCO is applied to the analysis of information technology products, seeking to quantify the financial impact of deploying a product over its life cycle . These technologies include software and hardware, and training. Technology deployment can include

936-427: The following as part of TCO: In the case of comparing TCO of existing versus proposed solutions, consideration should be put toward costs required to maintain the existing solution that may not necessarily be required for a proposed solution. Examples include cost of manual processing that are only required to support lack of existing automation, and extended support personnel. Total cost of ownership can be applied to

975-457: The foundation of a standardized and holistic approach to implementing TCO key principles. Implementation of TCO key principles can improve decision making, maximizing financial strategies over the life of an asset, starting at the planning and design stage and extends to the end of the asset's life. APPA 1000-2, slated for publication in 2019, will focus on implementation and application of key TCO principals in facility management. The TCO concept

1014-450: The future. APPA, an ANSI Accredited Standards Developer, published APPA 1000-1 – Total Cost of Ownership for Facilities Asset Management (TCO) – Part 1: Key Principles as an American National Standard in December 2017.  APPA 1000-1 provides financial officers, facility professionals, architects, planners, construction workforce, and operations and maintenance (O&M) personnel

1053-401: The hull length overall (LOA) exceeds 27 feet (8.2 m), people generally refer to the boat as an offshore one-design boat or yacht. In other classes, the one-design class may have organized around an existing fleet of similar boats that traditionally existed together often for commercial purposes such as sailing canoes, dhows , and skipjacks , or boats that developed a common hull form over

1092-441: The initial manufacturing cycle time and cost to make parts. TCO includes a variety of cost of doing business items, for example, ship and re-ship, and opportunity costs, while it also considers incentives developed for an alternative approach. Incentives and other variables include tax credits, common language, expedited delivery, and customer-oriented supplier visits. TCO, when incorporated in any financial benefit analysis, provides

1131-517: The keel. Cutter rig with 6 ft bowsprit. Designed by H. W. White, ten were built in 1895/6 by Messrs. White Brothers of Itchen Ferry, Southampton and another twelve were built in the following year. The class enjoyed ten years of keen racing but the Metre Rule, which was introduced in 1907 effectively killed the class. The only boat still afloat is Rosenn, formally Eilun, sail number 6. Now, fully restored, she has been identified as meriting inclusion in

1170-458: The outside of the wheels. Cost of ownership Total cost of ownership ( TCO ) is a financial estimate intended to help buyers and owners determine the direct and indirect costs of a product or service. It is a management accounting concept that can be used in full cost accounting or even ecological economics where it includes social costs . For manufacturing, as TCO is typically compared with doing business overseas, it goes beyond

1209-917: The rewards are greatly improved acceleration and much lower emissions. Powertrain development for diesel engines involves the following: exhaust gas recirculation (EGR), and advanced combustion. Spark ignition engine development include: fuel injection , including the gasoline direct injection variant, as well as improving volumetric efficiency by using multi-valves per cylinder, variable valve timing , variable length intake manifolds , and turbocharging . Changes also include new fuel qualities (no sulphur or aromates ) to allow new combustion concepts. So-called "combined combustion systems" (CCV) or "diesotto" cycles are based on synthetic fuels (synthetic diesel, biomass to liquid (BTL) or gas to liquid (GTL)). BEVs , FCEVs and PHEV powertrains are expected to reach cost parity with ICE powertrains in 2025. The manufacturing of powertrain components and systems

One-design racing - Misplaced Pages Continue

1248-576: The specification is published but the boats may only be produced by licensed manufacturers with usually only one builder in any country or region. Examples are the Olympic Finn and 470 but in both these classes a single manufacturer has succeeded in building faster boats than all other manufacturers. However, in the Optimist dinghy, one of the world's largest classes, a tighter specification introduced in 1995/with ongoing scrutiny has resulted in boats from

1287-443: The structure and systems of a single building or a campus of buildings. Pioneered by Doug Christensen and the facilities department at Brigham Young University starting in the 1980s, the concept gained more traction in educational facilities in the early 21st century. The application of TCO in facilities goes beyond the predictive cost analysis for a new building’s “first cost” (planning, construction and commissioning), to factor in

1326-598: The two distinct engine designs available from Chevrolet and Honda prevent IndyCar from being a “true” spec series. The same applies to the Super Formula series. All teams compete in nearly identical Dallara SF23 models, but use engines supplied from Honda and Toyota , preventing it from being a true spec series. There are two primary methods of competition in sailboat racing : One-design and handicap racing (e.g. Portsmouth Yardstick , Performance Handicap Racing Fleet and Leading Yard Stick ). One design refers to

1365-540: The use of a common engine and chassis. Examples of one-make racing series from around the world included the Dodge Viper Challenge , Ferrari Challenge , Porsche Carrera Cup and Supercup , Radical European Masters , Mini Challenge and Commodore Cup . There are also various formula categories that use one-make racing, such as Formula 2 (which since 2011 exclusively uses a car design by Dallara ), Formula Renault , Formula Mazda , Formula Car Challenge , and

1404-405: The vehicle wheels. All-electric vehicles ("electric cars") eliminate the engine altogether, relying solely on electric motors for propulsion. Occasionally the term powerplant is casually used to refer to the engine or, less often, the entire powertrain. A motor vehicle's driveline or drivetrain consists of the parts of the powertrain excluding the engine. It is the portion of a vehicle, after

1443-665: The years (such as A-Scows ). In contrast to 'one-design', other sailboats race under a variety of handicapping rules and formulas developed to allow different type boats to compete against one another. Formula rules include the Square Metre Rule , the Ton class , the Universal Rule , and the Metre Rule . Handicap rules include Portsmouth Yardstick , PHRF , IOR , IMS , IRC , Americap and LYS . There have been several attempts to bring

1482-761: Was patronised by some of the most energetic and best known yacht owners in the Solent, Portsmouth and Southampton waters including Sir Philip Hunloke, the King's yachtmaster. Formed under the auspices of the Solent Sailing Club, the class was adopted by the Royal Yacht Squadron and the Island Sailing Club in 1895. The dimensions of the boats were length overall, 33 ft 3 in; Waterline length, 25 ft; Beam, 7 ft 9 in; Draft, 5 ft; Sail area, 750 sq ft.; Displacement, 5 tons with 2 tons 13 cwt. of lead in

1521-558: Was planned for the 1940 Olympic championships. Powertrain In a motor vehicle , the powertrain comprises the main components that generate power and deliver that power to the road surface, water, or air. This includes the engine , transmission , drive shafts , differentials , and the final drive ( drive wheels , continuous track as in military tanks or caterpillar tractors, propeller , etc.). Hybrid powertrains also include one or more electric traction motors that operate to drive
