Thesis engine

Terminology[ edit ] The word engine derives from Old French enginfrom the Latin ingenium—the root of the word ingenious.

Early life[ edit ] Whittle's birthplace in EarlsdonCoventry, England. He quickly developed practical engineering skills while helping in his father's workshop, and being an enthusiastic reader spent much of his spare time in the Leamington reference library, reading about astronomy, engineering, turbines, and the theory of flight.

He lasted only two days: This time he passed the physical and, in September that year, Boy Whittle, F started his three-year training as an aircraft Thesis engine in No. Whittle hated the strict discipline imposed on apprentices and, convinced there was no hope of ever becoming a pilot he at one time seriously considered deserting.

The quality of these attracted the eye of the Apprentice Wing commanding officer, who noted that Whittle was also a mathematical genius. Being an ex-apprentice amongst a majority of ex-public schoolboys, life as an officer Thesis engine was not easy for him, but he nevertheless excelled in the courses and went solo in after only In Future Developments in Aircraft Design he showed that incremental improvements in existing propeller engines were unlikely to make such flight routine.

Instead he described what is today referred to as a motorjet ; a motor using a conventional piston engine to provide compressed air to a combustion chamber whose exhaust was used directly for thrust — essentially an afterburner attached to a propeller engine. The idea was not new and had been talked about for some time in the industry, but Whittle's aim was to demonstrate that at increased altitudes the lower outside air pressure would increase the design's efficiency.

For long-range flight, using an Atlantic-crossing mailplane as his example, the engine would spend most of its time at high altitude and thus could outperform a conventional powerplant. Pondering the problem he thought: The remaining exhaust thrust would power the aircraft. His continuing reputation for low flying and aerobatics provoked a public complaint that almost led to his being court-martialled.

He became a popular and gifted instructor, and was selected as one of the entrants in a competition to select a team to perform the "crazy flying" routine in the Royal Air Force Air Display at RAF Hendon.

He destroyed two aircraft in accidents during rehearsals but remained unscathed on both occasions. After the second incident an enraged Flight Lieutenant Harold W.

Raeburn said furiously, "Why don't you take all my bloody aeroplanes, make a heap of them in the middle of the aerodrome and set fire to them — it's quicker!

Johnson, in turn, took the concept to the commanding officer of the base. This set in motion a chain of events that almost led to the engines being produced much sooner than actually occurred. Griffith had published a paper on compressors and turbines, which he had been studying at the Royal Aircraft Establishment RAE.

He showed that such designs up to this point had been flying "stalled", and that by giving the compressor blades an aerofoil-shaped cross-section their efficiency could be dramatically improved.

The paper went on to describe how the increased efficiency of these sorts of compressors and turbines would allow a jet engine to be produced, although he felt the idea was impractical, and instead suggested using the power as a turboprop. At the time most superchargers used a centrifugal compressorso there was limited interest in the paper.

Encouraged by his commanding officer, in late Whittle sent his concept to the Air Ministry to see if it would be of any interest to them.

With little knowledge of the topic they turned to the only other person who had written on the subject and passed the paper on to Griffith.

Griffith appears to have been convinced that Whittle's "simple" design could never achieve the sort of efficiencies needed for a practical engine. After pointing out an error in one of Whittle's calculations, he went on to comment that the centrifugal design would be too large for aircraft use and that using the jet directly for power would be rather inefficient.

The RAF returned his comment to Whittle, referring to the design as being "impracticable". Since the RAF was not interested in the concept they did not declare it secret, meaning that Whittle was able to retain the rights to the idea, which would have otherwise been their property. Johnson arranged a meeting with British Thomson-Houston BTHwhose chief turbine engineer seemed to agree with the basic idea.

This posting came as a surprise for he had never previously flown a seaplane, but he nevertheless increased his reputation as a pilot by flying some 20 different types of floatplanes, flying boats, and amphibians.

His performance in the course was so exceptional that in he was permitted to take a two-year engineering course as a member of Peterhousethe oldest college of Cambridge Universitygraduating in with a First in the Mechanical Sciences Tripos. Shortly afterwards, in May, he received mail from Rolf Dudley-Williamswho had been with him at Cranwell in the s and Felixstowe in The two proposed a partnership that allowed them to act on Whittle's behalf to gather public financing so that development could go ahead.

Whyte was impressed by the year-old Whittle and his design when they met on 11 September The impression he made was overwhelming, I have never been so quickly convinced, or so happy to find one's highest standards met This was genius, not talent.

Whittle expressed his idea with superb conciseness: They have hundreds of parts jerking to and fro, and they cannot be made more powerful without becoming too complicated. It was favourable and Falk then agreed to finance Whittle.Christopher Bollyn is a well-travelled writer and an investigative journalist who has done extensive research into the events of September 11, , the conflict in Middle-East and the health effects caused by exposure to depleted uranium.
