Whittle demonstrated an aptitude for engineering and an interest in flying from an early age. At first he was turned down by the RAF but, determined to join the force, he overcame his physical limitations and was accepted and sent to No. 2 School of Technical Training to join No 1 Squadron of Cranwell Aircraft Apprentices. He was taught the theory of aircraft engines and gained practical experience in the engineering workshops. His academic and practical abilities as an Aircraft Apprentice earned him a place on the officer training course at Cranwell. He excelled in his studies and became an accomplished pilot. While writing his thesis he formulated the fundamental concepts that led to the creation of the turbojet engine, taking out a patent on his design in 1930. His performance on an officers' engineering course earned him a place on a further course at Peterhouse, Cambridge, where he graduated with a First.[2][3]
The Air Ministry still saw little immediate value in the effort (they regarded it as long-range research[33]), and having no production facilities of its own, Power Jets entered into an agreement with steam turbine specialists British Thomson-Houston (BTH) to build an experimental engine facility at a BTH factory in Rugby, Warwickshire.[34] Work progressed quickly, and by the end of the year 1936 the prototype detail design was finalised and parts for it were well on their way to being completed, all within the original 2,000 budget.[5][35] However, by 1936, Germany had also started working on jet engines (Herbert A. Wagner at Junkers and Hans von Ohain at Heinkel) and, although they too had difficulty overcoming conservatism, the German Ministry of Aviation (Reichsluftfahrtministerium) was more supportive than their British counterpart.[36] Von Ohain applied for a patent for a turbojet engine in 1935 but having earlier reviewed and critiqued Whittle's patents, had to narrow the scope of his own filing. [37]In Spain, air-force pilot and engineer Virgilio Leret Ruiz had been granted a patent for a jet engine in March 1935, and Republican president Manuel Azaña arranged for initial construction at the Hispano-Suiza aircraft factory in Madrid in 1936, but Leret was executed months later by Francoist Moroccan troops after commanding the defence of his seaplane base near Melilla at the onset of the Spanish Civil War. His plans were hidden from the Francoists and secretly handed to the British embassy in Madrid a few years later when his wife, Carlota O'Neill, was released from prison.[38][39]
In December 1937, Victor Crompton became Power Jets first employee, as an assistant to Whittle. Because of the hazardous nature of the work being carried out, development was moved largely from Rugby to BTH's lightly used Ladywood foundry at nearby Lutterworth in Leicestershire in 1938. Tests with a reconstructed W.U. engine commenced on 16 April 1938, and proceeded until a catastrophic failure of the turbine on 6 May. Yet, the engine ran for 1 hour and 45 minutes, and generated a thrust of 480 pounds-force (2,100 N) at 13,000 rpm. Another W.U. engine reconstruction was started on 30 May 1938, but using ten combustion chambers to match the ten compressor discharge ducts. Avoiding a single large combustion chamber made the engine lighter and more compact. Tests commenced with this third W.U. on 26 October 1938.[48]
Whittle had already studied the problem of turning the massive W.U. into a flyable design, with what he described as very optimistic targets, to power a little aeroplane weighing 2,000 lb with a static thrust of 1,389 lb.[53] The designed maximum thrust for the W.1 was 1,240 pounds-force (5,500 N), while that for the W.2, was 1,600 pounds-force (7,100 N) The W.2 was to be flown in the twin-engine Gloster Meteor fighter, designated F.9/40, but the engine was replaced with the W.2B, having a designed static thrust of 1,800 pounds-force (8,000 N). An experimental version of the W.1, designated W.1X, was used as a mock-up for the E.28 installation. A second E.28 was powered by the W.1A, that incorporated W.2 features such as air cooling of the turbine and a different compressor intake. On 26 March 1940, the jet engine was listed as a potential war winner by Air Marshal Tedder, and given the associated priority.[54]
On 10 December 1941 Whittle suffered a nervous breakdown, and left work for a month.[60] However, by the end of January 1942, Power Jets had three W.2B engines, two built by Rover. In February 1942, flight trials of the W.1A engine began in the E.28, which reached 430 mph (690 km/h) at 15,000 feet (4,600 m). On 13 March 1942, Whittle started work on a redesign of the W.2B, referred to as the W.2/500. On 13 September 1942, W.2/500 performance tests matched predictions, showing a thrust of 1,750 pounds-force (7,800 N) at full speed. In October 1941, the Ministry approved a new factory to be built outside Whetstone, Leicestershire.[69]
On 11 December 1942 Whittle had a meeting with Ministry of Aircraft Production Wilfrid Freeman and Air Marshal Linnell. According to Whittle, "He made it clear that he had definitely decided to transfer Barnoldswick and Clitheroe to Rolls-Royce management." Spencer Wilks of Rover met with Hives and Hooker at the "Swan and Royal" pub, in Clitheroe, near the Barnoldswick factory. By arrangement with the Ministry of Aircraft Production[71] they traded the jet factory at Barnoldswick for Rolls-Royce's tank engine factory in Nottingham.Testing and production ramp-up was immediately accelerated. By January 1943, Rolls-Royce had achieved 400 hours of run time, ten times Rover's number of the previous month, and in May 1943, the W.2B passed its first 100-hour development test at 1,600 pounds-force (7,100 N) of thrust.[72]
INVEST IN R&D, REVITALIZE MANUFACTURING AND SMALL BUSINESSES, AND TRAIN AMERICANS FOR THE JOBS OF THE FUTURE
Half the jobs in our high growth, high wage sectors are concentrated in just 41 counties, locking millions of Americans out of a shot at a middle-class job. President Biden believes that, even in the face of automation and globalization, America can and must retain well-paid union jobs and create more of them all across the country. U.S. manufacturing was the Arsenal of Democracy in World War II and must be part of the Arsenal of American Prosperity today, helping fuel an economic recovery for working families. From the invention of the semiconductor to the creation of the Internet, new engines of economic growth have emerged due to public investments that support research, commercialization, and strong supply chains. President Biden is calling on Congress to make smart investments in research and development, manufacturing and regional economic development, and in workforce development to give our workers and companies the tools and training they need to compete on the global stage. Specifically, President Biden is calling on Congress to:
Invest in Workforce Development:
As more Americans rejoin the workforce or seek out new opportunities in a changing economy, there is a greater need for skills development opportunities for workers of all kind. In order to ensure workers have ready access to the skills they will need to succeed, and to improve racial and gender equity, President Biden is calling on Congress to invest $100 billion in proven workforce development programs targeted at underserved groups and getting our students on paths to careers before they graduate from high school. His plan will:
The Chinese laborers proved to be tireless workers, and Crocker hired more of them; some 14,000 were toiling under brutal working conditions in the Sierra Nevada by early 1867. (By contrast, the work force of the Union Pacific was mainly Irish immigrants and Civil War veterans.) To blast through the mountains, the Central Pacific built huge wooden trestles on the western slopes and used gunpowder and nitroglycerine to blast tunnels through the granite.
Alfred Nobel was born in Stockholm on 21 October 1833. His father, Immanuel Nobel, was an engineer and inventor who built bridges and buildings in Stockholm. In connection with his construction work Immanuel Nobel also experimented with different techniques for blasting rocks.
As the war ended and conditions changed, Immanuel Nobel was again forced into bankruptcy. Immanuel and two of his sons, Alfred and Emil, left St. Petersburg together and returned to Stockholm. His other two sons, Robert and Ludvig, remained in St. Petersburg. With some difficulties they managed to salvage the family enterprise and then went on to develop the oil industry in the southern part of the Russian empire. They were very successful and became some of the wealthiest persons of their time.
If there is one constant to the life and career of Lonnie Johnson, it is curiosity. From his childhood when he examined how toys worked to becoming the inventor of the world-famous Super Soaker, to the creation of the JTEC, Johnson was never content to rest on past achievements. His curiosity keeps him seeking, inventing and inspiring.
Occasionally, the energy required to quickly inflate airbags can cause injury to people sitting or thrown too close to the airbag before it deploys. This was a serious concern with the first generations of frontal airbags, which deployed with greater force.
In 2011 Ford rolled out an inflatable seat belt aimed at reducing rear-seat injuries. The inflatable seat belt is intended to enhance protection for adults and for children using booster seats or seat belts alone. In a crash, the shoulder belt inflates, distributing crash forces across the torso and chest.
Rear seat airbags are being developed to provide head protection for rear passengers. Rear seat airbags are located in the back of the front seat and deploy with less force than traditional airbags. They are only partially inflated, unlike normal, full-powered airbags, so even if the airbags contact objects or child seats, they deflect instead of striking them. Mercedes-Benz is planning to introduce this optional airbag on the next generation of S-Class.
