5 Introduction To An Imaginative Idea The jet engine is one of the most important inventions of all time, if my great grandpa (Sir Frank Whittle) had not invented the jet engine then we would still be using propellers. It would probably take 9 hours just to fly to Japan, but nowadays you can get there in a few hours. YUCK! Airplane food is just about the worst food you could expect to be served, so imagine being a pilot and eating the same food over and over again. Airplane food actually used to be made on board, and was much better, but for cost effectiveness they started serving prepackaged meals.

6 Engine Innovator Air Commodore Sir Frank Whittle (1 June August 1996) was a British Royal Air Force (R.A.F.) engineer air officer. Years of service: He is credited with single handedly inventing the turbojet engine. Whittle's engines were developed some years earlier than those of Germany's Dr. Hans von Ohain who was the designer of the first operational jet engine. From an early age Sir Frank Whittle showed a high interest in engineering and flying. Sir Frank Whittle other jobs were: BOAC technical advisor, Shell Oil engineer, engineer for Bristol Aero Engines, NAVAIR Professor at the US Naval Academy. Shy Boy Becomes Daredevil Pilot After two years attending Milverton School, Whittle got into a secondary school which in due course became Leamington College for Boys, but when his father's business faltered there was not enough money to keep him there. Milverton School Leamington College for Boys R.A.F. He quickly developed engineering skills while helping in his father's workshop, and being an book worm (like me), he spent much of his spare time in the Leamington reference library, reading about astronomy, engineering, turbines, and the theory of flight. At the age of 15, determined to be a pilot, he went to join the RAF.

7 R.A.F. A Testing Time For Frank Whittle In January 1923, having passed the RAF entrance test with flying colours Whittle reported to R.A.F. Halton (RAF Halton is one of the largest Royal Air Force stations in the United Kingdom) as an Aircraft Apprentice. He lasted only two days because he was to short (5ft tall), and had a two small chest measurement. He then put himself in a training programme and special diet devised by a physical training instructor at Halton to build up his physique, only to fail again six months later, when he was told that he could not be given a second chance, even though he already had added three inches to his height and chest. Undeterred, he applied again under an different name and put himself as a candidate at the No 2 School of Technical Training RAF Cranwell. This time he passed the physical, and in September that year, Boy Whittle F started his three-year training as an aircraft mechanic in No. 1 Squadron of No. 4 Apprentices Wing of RAF Cranwell. The background is fighter jets celebrating The Diamond Jubilee! What On Earth Is The R.A.F.? The Royal Air Force (RAF) is the aerial warfare service branch of the British Armed Forces. Formed toward the end of the First World War on 1 April 1918,[2] it is the oldest independent air force in the world.[3] Following victory over the Central Powers in 1918 the RAF emerged at the time the largest air force in the world. [4] Since its formation, the RAF has taken a significant role in British military history, in particular, playing a large part in the Second World War where it fought its most famous campaign, the Battle of Britain. HANDY HINT: If you want to join the R.A.F. here are the requirements: Height : min 163cm and maximum 193cm. (5'3-6'3.5) Sitting Height: maximum 100cm. Buttock to knee length : maximum 67cm. Buttock to heel length : maximum 122cm.

8 Turbojet Engine A jet engine is a reaction engine discharging jet (an efflux fluid) that produces thrust with jet propulsion (jet propulsion is thrust produced by passing a jet of matter (typically air or water) The type of jet engine that I am talking about is the turbojet engine: The turbojet is a jet engine usually used in aircraft. It consists of a gas turbine with a propelling nozzle. The gas turbine has an air inlet, a compressor, a combustion chamber, and a turbine (that drives the compressor). The compressed air from the compressor, is heated by the fuel in the combustion chamber and then allowed to grow through the turbine. The turbine exhaust is then expanded in the propelling nozzle where it is accelerated to high speed to provide thrust. Fun Facts About Planes Today: American Airlines saved $40,000 a year by taking out ONE olive from each salad they served! In 1971, a 17 year old German girl was the sole survivor of a plane crash in the Amazon surviving 10 days on her own!

9 End Of A Productive Engineer Sir Frank Whittle died of lung cancer on August 9, 1996 in Columbia, Maryland, United States at 89 years old.

10 Glossary Engineer - a person who designs, builds, or maintains engines, machines, or structures. Compressor - an instrument or device for compressing something. Candidate - a person who applies for a job or is nominated for election: Inventor - a person who invented a particular process or device or who invents things as an occupation. Engine - a machine with moving parts that converts power into motion. Combustion - the process of burning something. Nozzle - a cylindrical or round spout at the end of a pipe, hose, or tube used to control a jet of gas or liquid. Turbine - a machine for producing continuous power in which a wheel or rotor, typically fitted with vanes, is made to revolve by a fast-moving flow of water, steam, gas, air, or other fluid. Aerial - a rod, wire, or other structure by which signals are transmitted or received as part of a radio or television transmission or receiving system.
