October 1945_ whittle reflects on his jet engine _ the engineer

It should go without saying that Sir Frank invented the jet propulsion gas turbine, and, in doing so, created a market that between 2014–2023 alone will require 55,000 new civil aero engines.

By contrast, Sir Frank’s first jet propulsion gas turbine – the W1 – delivered 1,240lb of thrust, rising to 1,600lb with the development of the W2.

A remarkable element of the jet engine’s story is the fact that Sir Frank was rejected twice by the RAF; an organisation that would ultimately reward him with a commission and an education.

No less remarkable was the fact that just a few months after the end of the Second World War, Air Commodore Frank Whittle, CBE, RAF, MA, Hon. Gas vs electric water heater MI Mech E had set about contributing a series of articles to The Engineer that would candidly and eloquently explain how the jet engine came into being.

“I first started thinking about this general subject in 1928, in my fourth term as a flight cadet at the RAF. Electricity quiz and answers College, Cranwell,” he wrote. K electric share price “Each term we had to write a science thesis, and in my fourth term I chose for my subject the future development of aircraft. Hp gas Among other things, I discussed the possibilities of jet propulsion and of gas turbines; but it was not until 18 months later, when on an instructors’ course at the Central Flying School, Wittering, that I conceived the idea of using a gas turbine for jet propulsion. Gas refrigerator not cooling I applied for my first patent in January 1930.”

The idea was submitted to the now defunct Air Ministry but turned down due to perceived difficulties surrounding a gas turbine. Gas 87 Similarly, Sir Frank tried and failed to attract funding from a number of sources.

“I gave up hope of ever getting the idea to the practical stage, but continued to do paperwork at intervals, until, in May 1935, when I was at Cambridge as an engineer officer taking the Tripos course, I was approached by two ex-RAF officers (Mr RD Williams and Mr JCB Tinling), who suggested that they should try to get something started,” he said. Gas x ultra strength directions “Although I had allowed the original patent to lapse through failure to pay the renewal fee, and although I regarded them as extremely optimistic, I agreed to co-operate. M gasbuddy app I thought that there was just a bare chance that something might come of it.”

With Messrs Williams and Tinling on board, Sir Frank was able to come to an arrangement with investment bankers OT Falk and Partners, leading to the formation of Power Jets in 1936.

The engine itself was to be a simple jet propulsion gas turbine having a single-stage centrifugal compressor with bilateral intakes, driven by a directly coupled single-stage turbine. Wb state electricity board recruitment 2015 Combustion was to take place in a single chamber through which the working fluid passed from the compressor to the turbine.

“We were going beyond all previous engineering experience in each of the major organs,” he said. R gasquet tennis “We were aiming at a pressure ratio of about 4/1 in a single-stage centrifugal blower when at the time, so far as we knew, a ratio of 2t/1 had not been exceeded. Gasco abu dhabi email address We were aiming at a breathing capacity in proportion to size substantially greater than had previously been attempted.

“The combustion intensity we aimed to achieve was far beyond anything previously attempted. Origin electricity account Finally, we had to get over 3,000 SHP out of a single-stage turbine wheel of about 16lin outside diameter, and to do it with high efficiency.”

“But it [the engine] accelerated out of control up to about half its designed full speed,” wrote Sir Frank. Electricity allergy “This happened several times, and altogether it was a very alarming business, so much so that in the early days the individuals in the vicinity did more running than the engine.”

Just shy of his 34th birthday, Sir Frank saw his invention provide power for the new Gloster E.28/39 on its maiden flight from RAF Cranwell in 1941.

My first job after the apprentice school at Rugby was in Factory Layout Dept. D cypha electricity where I was asked to draw up the layout for some test equipment in Turbine Department. Gas explosion On surveying the site I discovered it was occupied by machinery I didn’t recognise. Electricity electricity song Asking around I was told it was Whittle’s second prototype ! A worker at the site told me that when the prototype accelerated out of control Whittle was the only one with the courage to run forward and shut off the fuel supply. Gas water heater reviews 2013 Everyone else ran for shelter behind the large turbine castings in the area awaiting machining or assembly. E gasoline After asking for advice I arranged for the abandoned engine to be stored at the Lutterworth facility a few miles away. Electricity balloon experiment I have since wondered if any record was made of my arrangements or whether the engine was subsequently regarded as scrap metal and destroyed. Electricity calculator It should , of course, be in a museum. Gas 91 I have seen a similar engine in the Science Museum in London but have no way of knowing if it is the same one. Electricity magnetism and electromagnetic theory pdf My memory will be of Spring 1952.

More recent reading of Whittle’s achievements has suggested that his determination to progress his ideas set back gas turbine development rather than accelerated it because his combustion chambers reversed gas flow unlike Farnborough plans for continuous unidirectional flow as is current practice. Grade 9 electricity test and answers My guess is that although the Farnborough development would have been the shorter route to modern efficiencies their bureaucracy would meant others would have got there first. E 87 gasoline Whittle’s achievement was to actual create something that worked.
