George Lanchester

George Lanchester is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand George Lanchester rather than just read about it. In short: George Herbert Lanchester (1874 – 13 February 1970) was an English engineer. He was one of three brothers who played a leading role in the early development of the UK auto-industry.

Key takeaways

  • George Lanchester belongs to engineering; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect George Lanchester to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of George Lanchester from memory before moving on to harder problems.

Reference excerpt

George Herbert Lanchester (1874 – 13 February 1970) was an English engineer. He was one of three brothers who played a leading role in the early development of the UK auto-industry. In 1909, following the departure from full-time involvement with the company of his elder brother Frederick, George took over responsibility for the Lanchester Motor Company. Thereafter, while Frederick pursued his own glittering career as one of the leading automotive and aeronautical engineers of the time, it was George who ran the business the brothers had established together.

Early years In 1889, at the age of 15, George started an apprenticeship with the Forward Gas Engine Company in Birmingham. His elder brother was already Works Manager with the same company. Four years later, setting a pattern for the future, Frederick left the company to pursue a full-time career as a research scientist, concentrating on the field that would later come to be known as aerodynamics. George, though still only 19, took over his brother's position as Works Manager. Between 1894 and 1898 the brothers worked together on the development of a petrol (gasoline) powered passenger car. There being no established auto-component industry, a large number of components had to be designed and constructed from scratch, and much of this detailed work was undertaken by George, both for the first Lanchester car and for two subsequent mechanically identical prototypes.

Lanchester Motor Company

In 1899, Frederick and George, along with their middle brother Frank set up the Lanchester Engine Company. Frederick, as leader of the triumvirate, was chief designer and general manager while Frank took on the duties of a sales manager. George's role could be defined as that of Production Manager, albeit with a wider range of duties and responsibilities than that title implies. He quickly developed deep insights into the nascent techniques of auto-production methodology. His duties also extended to delivering cars to the more important customers, reportedly on one occasion suffering twenty tire bursts or punctures between Birmingham and Brighton on a single delivery job. The three brothers were both the directors and the principal owners of the Lanchester Motor Company and there are suggestions that the relationship between them in these circumstances was sometimes a tense one. After Frederick left the company in 1909 to pursue a more independent career, George added "Chief Designer" to his portfolio of company responsibilities, though Frederick continued to provide input on a consultancy basis, and new models appearing in the aftermath of this change continued to reflect the elder brother's inputs more than those of George, being in large measure developments of existing 20 hp and 28 hp predecessors that had been introduced between 1904 and 1906. The Sporting Forty was the first Lanchester to feature what would become a 'normal' bonnet/hood and appeared in 1914. It seems to have been the first new model for which George himself had been principally responsible, though here too he had less than a totally free hand, having reluctantly agreed to a requirement from fellow directors to incorporate a side-valve engine because that mimicked the engine design competitor manufacturers were using at the time. In any event, for the United Kingdom 1914 was the year the First World War broke out and only six of these models had been sold before the plant was switched over to war production.

War and its aftermath The British and the Russians were on the same side in the First World War, both states having ostensibly declared war in support of smaller states attacked by the Austrians or their German allies: the Lanchester armoured cars on the 38 hp chassis proved themselves particularly effective on the Russian front, since their wick carburettors were not clogged up by the Russian fuel in the same way as conventional spray carburettors used in other British army vehicles. The aftermath of war saw a rapid return for the Lanchester 40, but now George was able to install an overhead camshaft engine, and this set the pattern for the six- and eight-cylinder Lanchester engines which built the company's name between 1919 and 1931. Despite the old name, the post-war Lanchester 40 was in many ways a new car at a time when some competitors were offering little-changed versions of pre-war designs. The Lanchester bodies used aluminium panels: the three-speed epicyclic gear-boxes and cantilever rear springs were, however, familiar from Lanchester's own pre-war designs. The Lanchester 40 on display at the 1919 London Motor Show was equipped beyond the standard level, with silk blinds and ivory door handles, prompting one eminent visitor to the Lanchester stand to suggest to King George V that his car was "very fine...., but more suited to a prostitute than a prince, don't you think?" Lanchesters nevertheless found favour with the British establishment in general and the British royal family in particular: by the time the motor show visitor died, early in 1936 his granddaughter, who in her turn would inherit many of his titles and his status as Elizabeth II, had already made her own first public appearance in her father's Lanchester 40. During the 1920s Lanchesters competed directly with Rolls-Royce, taking care to undercut equivalent products from their competitors by £50. Lanchesters were distinguished by the smoothness of the engines which George designed, paying close attention to detail. A particular triumph was the straight-eight engine that entered production in 1926 in the Lanchester Thirty, replacing the six-cylinder Lanchester 40. The driveshaft was located to minimise vibration, and close attention was paid to manifold design, with George using transparent pipes to locate and remedy deposits appearing on the induction pipes at certain throttle settings.

Worked examples

Example 1 — a first encounter with George Lanchester

Start with the simplest possible case. Write down what George Lanchester claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to George Lanchester before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about George Lanchester ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of George Lanchester

In research
George Lanchester appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses George Lanchester in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
George Lanchester is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1874 births, 1970 deaths, 20th-century English engineers, so understanding it makes those chapters shorter.
In everyday life
Look for George Lanchester outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
