Psychrometric Chart Long before humans appeared on earth, nature had given. Hero, an Egyptian scientist who lived in Alexandria around B. Attached to the sphere were two small pipes or jets whose openings were at right angles to the axis of rotation of the sphere.
When the water in the bowl was boiled, the steam shooting from the two small jets caused the sphere to spin, like the lawn sprinkler is.
This phenomenon will be explained in chap. Incidentally, the aeolipile was only one of many inventions credited to Hero, which include a water clock, a compressed-air catapult, and a hydraulic organ. Around A. As the hot air from the fire rose, it passed. The invention of gunpowder allowed the continued development of the reaction principle. His plan was simple. A series of rockets were lashed to a chair under which sledlike runners had been placed.
The phrase the rockets' red glare in our national anthem refers to the use of rockets by the British in besieging Fort McHenry in Baltimore during the war of A further application of the jet propulsion principle, usJng what was probably the first actual impulse turbine, was the invention of a stamping mill Fig.
The vehicle illustrated in Fig. The wagon consisted essentially of a large boiler mounted on four wheels. Steam generated by a fire built below the boiler was allowed to escape through a nozzle facing rearward. In John Barber, an Englishman, was the first to patent a design using the thermodynamic cycle of the modem.
Between and , many people supplied ideas that laid the foundation for the modem gas turbine engine as we know it today. When in Frank Whittle submitted his patent application for a jet aircraft engine, he drew from the contributions of many people:. This engine operated on the same cycle principle as the modem closed-cycle gas turbine.
F S to lt z - Designed an engine approaching the concept of the modem gas turbine engine. Sanford A. Moss Fig. Credit for the basic idea for the turbosupercharger is given to Rateau of France; it is in reality very similar to a jet engine, lacking only the combustion chamber Fig.
Griffith-Member of the British Royal. Chapter 1 Background and Development. The work of many others, in addition to those mentioned, preceded Whittle's efforts. Several jet engine developments were also occurring concurrently in other countries. These developments are discussed on the following pages. In , at the time that Dr. Griffith was involved in his work with compressors and other parts of the gas turbine, Whittle Fig.
College in Cramwell, England, submitted a thesis. It was not until eighteen months later that this idea crystallized, and he began to think seriously about using the gas turbine engine for jet propulsion. By January , Whittle's thinking on the subject had advanced to the point that he submitted a patent application on the use of the gas turbine for jet propulsion Fig.
In this patent were included ideas for the athodyd, or ramjet, which was removed from the specifications when it was determined that the ramjet idea had already been proposed. The period between and was one of frustration for Whittle and his coworkers. In , while at Cambridge studying engineering, he was approached by two former R.
They, in turn, would.
