Newton's Laws of Motion: Jet engines discharge a high velocity jet of gas
to generate thrust in accordance with Newton's laws of motion. Sir Isaac
Newton (1642 - 1726) was one of the world's greatest scientists. In 1686, he
compiled his three laws of motion, which were used 300 years later when the jet
engine was invented. But what are Newton's laws of motion?
Definition of Newton's laws of motion - Newton's First Law of Motion:
Sir Isaac Newton's First Law of Motion, also referred to as the law of inertia,
states that every object moves in a straight line unless acted upon by a force.
Definition of Newton's laws of motion - Newton's Second Law of Motion: Sir
Isaac Newton's Second Law of Motion PROVIDES an exact relationship between
force, mass, and acceleration that is expressed by the mathematical equation:
F=MA or FORCE = MASS times ACCELERATION.
Definition of Newton's laws of motion - Newton's Third Law of Motion: Sir
Isaac Newton's Third Law of Motion is that for every action there is an equal
and opposite re-action. Newton's Third Law of Motion can be illustrated in
respect of a rocket. The action of a rocket is to push down on the ground with
the force of its powerful engines, and the reaction is that the ground pushes
the rocket upwards with an equal force.
Who invented the Jet Engine? Frank Whittle invented the Jet Engine in 1930
using Sir Isaac Newton's Three Laws of Motion.

Fact 1: Who invented the Jet Engine? Prior to the invention of the Jet Engine
by Frank Whittle in 1930, traditional piston engines were used for aircraft.
Fact 2: Who invented the Jet Engine? What is the difference between a jet
engine and a piston engine? A Jet Engine is more complex than a piston engine. A
Jet Engine is powered by fuel and air to power constantly spinning turbine
blades, whereas a piston engine uses fuel to move pistons through a four stroke
Fact 3: Who invented the Jet Engine? Before the invention of the Jet
Engine aeronautical engineers believed that airplane speeds had reached their
limit. The invention of the Jet Engine increased both the power and speed of
Fact 4: Who invented the Jet Engine? The Jet Engine was invented by Frank
Whittle in 1930 during the Interwar Era of inventions (1918 - 1939).
Fact 5: Who invented the Jet Engine? A German physicist called Hans von
Ohain (1911 - 1998) also began to independently develop turbojet designs during
roughly the same period as Frank Whittle but Ohain started 7 years after Whittle
had patented his design in 1930. Hans von Ohain is credited as the designer of
the first operational jet engine, not as its inventor.
Fact 6: Who invented the Jet Engine? The inventor of the Jet Engine, Frank Whittle, was born on June 1, 1907 in Earlsdon, Coventry, England, UK and died on August 9, 1996.
Fact 7: Who invented the Jet Engine? The early years of Frank Whittle were spent in Earlsdon, Coventry, England where he was raised by his family.
His father, Moses Whittle, was a mechanic and instilled a love of engines and
other machinery in his son. Frank developed an aptitude for engineering and a
great interest in aviation and airplanes,
which had only just been invented.
Fact 8: Who invented the Jet Engine? Frank Whittle was educated at
Milverton School and Leamington College for Boys. In 1923, when he was 15 years
old, he passed the entrance examination for the Royal Air Force (RAF) but failed
the physical due to his height (he was just 5 foot at the time) and for his
small chest and slight physique.
Fact 9: Who invented the Jet Engine? Frank Whittle was a determined young
man and undertook a rigorous exercise routine to build up his frame. After two
more attempts he managed to at last be accepted by the RAF.
Fact 10: Who invented the Jet Engine? Frank Whittle began his 3-year
training as an aircraft mechanic in No. 1 Squadron at RAF Cranwell in Sleaford,
Fact 11: Who invented the Jet Engine? At the age of 21 years old Frank
Whittle qualified as a pilot officer in 1928. During his training he had written
a thesis in which he argued that planes needed to fly at high altitudes, where
air resistance is much lower, in order to achieve high speeds and long ranges.
Fact 12: Who invented the Jet Engine? His thesis won the Andy Fellowes
Memorial Prize for Aeronautical Sciences and began a journey that would
ultimately lead him to the invention of the Jet Engine.
Fact 13: Who invented the Jet Engine? His research had led him to believe
that conventional piston engines and propellers used for aircraft were
unsuitable for this purpose, concluding that rocket propulsion or gas turbines
driving propellers would be required.
Fact 14: Who invented the Jet Engine? He designed what is now referred to
as a motorjet that used an ordinary piston engine which instead of driving a
propeller, it drove a compressor. His Motorjet engine provided greater thrust
than a propeller alone mounted on a piston engine.
Fact 15: Who invented the Jet Engine? The Air Ministry turned Frank
Whittle's idea down so, undaunted, he submitted his first patent in 1930 for a
two- stage axial compressor feeding a single- sided centrifugal compressor. The
patent was subsequently granted in 1932. Frank Whittle married, Dorothy Mary Lee
in 1930 and the couple went on to have two sons.
Fact 16: Who invented the Jet Engine? Frank Whittle attended the
Officers’ Engineering Course at Henlow in 1932 and heavily involved in the
design of his first turbo-jet engine, the WU (Whittle Unit). His excellent marks
on the course resulted in the RAF deciding to send him to Cambridge University
to take a Mechanical Sciences Tripos for a a bachelor's degree in engineering.
Fact 16: Who invented the Jet Engine? Although the RAF were impressed
with Frank Whittle, they were indifferent to his ideas regarding his turbo-jet
engine. A friend of Whittle, and former Cranwell cadet, called R Dudley Williams
persuaded Frank to raise private capital to develop his ideas for the jet
Fact 17: Who invented the Jet Engine? In November 1935, Frank Whittle
secured financial backing for his ideas and, with the approval of the RAF,
founded Power Jets Ltd for the purpose of designing and manufacturing jet
Fact 18: Who invented the Jet Engine? Frank Whittle had his first engine
running in April 1937 but the project was beset with various technical problems
which he and his team eventually resolved. By this time their were concerns
regarding Germany and WW2 (1939 - 1945) broke out.
Fact 19: Who invented the Jet Engine? Frank Whittle's new test engine
began to look extremely useful and in 1940 the Air Ministry began to provide him
with the much needed money for his project.
Fact 20: Who invented the Jet Engine? In 1941, a flyable version of Frank
Whittle's jet engine was fitted to the Gloster E28/39 airframe that had been
specially built for the test. The jet propelled airplane first flew on May 15,
1941 at RAF Cranwell.
Fact 21: Who invented the Jet Engine? News of Frank Whittle's invention
reached the United States who requested a top secret meeting in Washington with
Frank Whittle's company, Power Jets Ltd.
Fact 22: Who invented the Jet Engine? By September 1942 the Americans had
built their first twin jet-engined fighter aircraft, the Bell P-59 Airacomet,
based on Whittle's ideas. It heralded the United States first step into the jet
Fact 23: Who invented the Jet Engine? The Frank Whittle W.2/700 turbojet
engine flew in the Gloster E.28/39 (also referred to as the "Gloster Whittle"),
the first British aircraft to fly with a turbojet engine.
Fact 24: Who invented the Jet Engine? The ground-breaking turbojet
engines were then installed in the Gloster Meteor, the first British jet fighter
and the Allies' only jet aircraft to achieve combat operations during WW2. The
Gloster Meteor aircraft commenced operations on 27 July 1944 with the RAF 616
Fact 25: Who invented the Jet Engine? Frank Whittle was promoted to Air
Commodore in 1944 and remained in the RAF until 1948 when he was forced to
retire due to ill-health.
Fact 26: Who invented the Jet Engine? On November 7, 1945, the first
official air speed record by a jet aircraft was set by a Meteor F.3 of 606 miles
per hour (975 km/h).
Fact 27: Who invented the Jet Engine? Frank Whittle was awarded an ex-gratia
sum of £100,000 (the equivalent to over 3 million pounds today) by the Royal
Commission on Awards to Inventors in 1948. He received the honor of a knighthood
in the same year.
Fact 28: Who invented the Jet Engine? Jet aircraft were commercially
successful as they were able to fly much higher, faster, and farther than older
piston powered engines making much of the world accessible within a single day's
travel for the very first time.
