The Wankel Engine
The Wankel engine is a type of internal combustion engine that is different than any other design. Even though it is much less common than the everyday gasoline engine, it is a much more practical design. It has proven to achieve higher horse power ratings while also having better efficiency than other gasoline engines of similar displacement.
The Wankel Engine’s efficiency comes from the design where instead of having multiple pistons doing one of the four strokes of a four stroke engine (intake, compression, combustion, exhaust) at a time, it has a single triangular shaped rotor doing all four at once. And because the rotor rotates in a circular pattern there in no stopping to change the direction of the rotor unlike pistons which have to change directions with every stroke, this also makes the Wankel Engine smoother and better balanced than traditional internal combustion engines. And also because there is usually only one or two rotors, depending on the engine, they are much more compact than the traditional inline or v-block designs.
How this marvel of engineering works is the rotor rides on an offset in the crankshaft, similar to a piston nand connecting rod assembly, and is rotated in an oval shaped case with ports for intake, exhaust and spark plugs. Incorporated into the rotor is a ring gear which had another gear that is stationary in the center, this planetary gear set is what keeps the rotor in time with the rest of the engine. The rotor creates three sealed areas where the different strokes will take place simultaneously, these three areas are sealed by strip of metal called the Apex seal which have the same function as the piston rings in a traditional internal combustion engine. The intake and ...

...agner, a local Nazi party leader, Felix Wankel was arrested and imprisoned in 1933 when the Nazi party took control of Germany. But soon after he was pardoned by Wilhelm Keppler who was an old friend of Wankel’s and also Adolf Hitler’s lead economic advisor. With the help of Wilhelm Keppler, Wankel was given funding’s for his own workshop and research center in Lindau to design and produce rotary valves and seals for the German Air Force’s aircraft and the German Navy’s torpedos, but all this ended with the war. In 1957 Felix Wankel produced the first working model of the Wankel Engine, only producing 21 horsepower it was still a great achievement.
And then in 1960 he was able to produce and start selling the first practical Wankel Engine, the KKM 250, which was used in the NSU Spider car. Felix Wankel died on October 8th 1988 in Heidelberg Germany at the age of 86.
In today’s world, the use of airplanes in wars or in everyday life has become a part of how we live as human beings. Removing the air forces of the world is like taking a step back in time when wars were only fought on land or sea. WWI began only eleven short years after the Wright brothers achieved powered flight in 19031 and yet aircrafts were being used for surveillance and eventually combat purposes. It is understood that these aircrafts were primitive, but they laid down the foundation for what we know today as fighter jets. The Fokker Eindecker “revolutionized air combat by successfully employing a synchronized forward -firing machine gun mounted on the engine cowling”2. Because this airplane became the first to successfully use a synchronized machine gun, it allowed its pilots to become the first aerial combat tactitions3.
Speer’s Rise in the Nazi Party Albert Speer rose from a mere architect to be one of the most influential Nazi leaders of the Third Reich, and self-admittedly Hitler’s closest friend. As a young, struggling architect Speer joined the Nazi Party as a ‘Septemberling’, and subsequently began to design many of the displays and structures that succeeded in promoting the Fuhrer Myth. Within the NSDAP Speer progressed to the position of Minister for Armaments and War Production in 1942, a reward for his superior managerial skills, and effectively utilised in the Nazi war effort. However, Speer’s rise in the NSDAP was often degraded by the members of the ‘old guard’, who thought that he had not earned his affluent position in Nazi society, but was rather a result of his friendship with Hitler. Albert Speer was born on 19th March 1905 into an upper-middle class family in the German city of Mannheim, and as a result of his families affluent position in society, they were relatively untouched by the Second World War.
The basic trimmer works by the engine driving a multi-bearing supported hardened steel shaft housed in an aluminium tube through a centrifugal clutch this shaft is connected to a “head” that holds a nylon line that spun at high revolutions per minute (RPM). This nylon line then cuts the grass by hitting the blades of grass at high speed, this cause the grass to be severed at the point of impact. Thus trimming the grass.
In the years WW2 was being fought plane designs progressed in leaps and bounds. From the old and obsolete designs of biplanes and triplanes the planes turned into worlds first Jet fighter, from ugly twin engine
In the future the automotive industries will need alternative fuel sources, in turn that means they will need alternative engines in their automobiles. The engines found in their cars will have to be changed to fit the new fuels being made. They have many directions in which they can go concerning engine types and fuel types.
The Physics Behind the Power of an Engine Insert the key, turn, and vroom. And down the road you go. Most people take for granted the strange conglomeration of metal and plastic under that sheet of metal, either in front or back of their vehicle. The engine, as you may have guessed, is a modern marvel- so to speak. They’re found in cars, trucks, boats, airplanes.
For over a century people have relied on automobiles, planes and trains as means of transportation, industry and agriculture, it has become such a successful necessity in the modern world that it has become a need for people to use them to get by. Now sure the three basic means of transportation are entirely different in the way the function and their use. All of these means of transportation would not be possible without this invention transportation could not be possible, The Internal Combustion Engine. You might be wondering what is exactly is an Internal Combustion Engine? It’s actually a simple concept but the way it’s performed can becoming very complex. The function of is to create a pulling force through a controlled explosion of compressed air and fuel inside a combustion chamber which then pulls a crank. Depending on what type of platform the engine is on will determine what the crank turns, for an example in a car the crank then turns either a front or rear axle which that axle transversely turns a wheel. In order for this engine to function in needs three elements - air, fuel and spark and without one of these elements the engine will not function, so it takes precise timing and careful planning by the Engineers to make the engine work as required.
In 1940 two physicists, Otto Frisch and Rudolf Peirels, sent a warning to the British government stating, “Germany is, or will be, in the possession of this weapon, it must be realized that no shelters are ava...

Heinz Guderian (1888-1954) was born in Kulm, West Prussia (now Chełmno, Poland). His family, like many Prussian’s, were historically landed gentry and lawyers with his father being the only soldier with whom he was closely related. Guderian, being the son of a soldier, moved around fairly extensively during his youth until he himself joined the military in 1907. During the First World War Guderian served as a signals officer, giving him insight into how technology could be used to facilitate military actions. Post-war Guderian found himself in the reduced 100,000-man German Army (Reichswehr) where he slowly began to develop his ideas of mobile warfare, gathering ideas from fellow military theorists J.F.C. Fuller, B.H. Liddell Hart, and Charles de Gaulle. This culminated in Guderian’s book Achtung – Panzer! which outlined his ideas on armor and aircraft in modern warfare. Guderian would eventually get to test his theories in action with the onset of the Second World War, making dramatic advances through Poland, France, and Russia. Perhaps because of his place as one of first to espouse both the theoretical and practical implementations of blitzkrieg he is sometimes referred to as the father of blitzkrieg and modern military theory.
Igor’s inspiration to build his own helicopter is said to have come from Leonardo da Vinci’s sketch of a helicopter. In 1908, while on vacation in Germany with his father, he saw pictures and read about Wilbur Wright’s European flights and decided to pursue aviation seriously. When Igor was 12, he made a small rubber powered helicopter that could fly at low heights. In 1909, he built his first helicopter, it had a wooden frame and a place for the pilot to sit. While working on his helicopter in 1910, he also built 3 planes and flew 2 of them. Even though both planes crashed, designing the planes gave him the belief that he could create flying machines. Russian composer, Sergei Rachmaninoff, gifted $5,000 to Sikorsky to keep his tiny company going during the early years. Two years after World War II started in Europe, on September 14, 1939, Sikorsky first flew the VS-300 helicopter while it was attached by lines to the ground. Even though Igor hoped the helicopter would be more popular, the skill needed to fly the helicopter made it not so popular.“On May 6, 1941, Sikorsky flew his VS-300 for 1 hour, 32 minutes, and 26 seconds, breaking the previous world record of 1 hour and 20 minutes that the Fa-61 had held since 1937.”-Don Berliner. Igor revealed the VS-300 helicopter to President Henry Ford at the Edison Museum in Michigan on October 7, 1943. When Sikorsky was 21, he had built his first good
The jet engine is a great mechanical piece of engineering. It has been used in almost all aircraft since its invention. This one improvement in aircraft allowed aircraft to fly higher, faster, and more efficient. The turbocharged engine invented by GE was the main building block for other engines. Since its invention, the jet engine has been the workhorse for all jet powered aircraft.
Have you ever wondered how you would get around without your car? Rudolf Diesel created the perfect thing, a Diesel engine. Now with the invention of an engine, we can get wherever we need to go. Rudolf diesel’s life and invention has impacted the world greatly.
Seeing and selling bicycles for twenty-two years must have been boring for Schulte so he did some experimenting with different engines and fitted them into a bicycle frame to make his very own gas powered bicycle. With understudy Mauritz Schulte who also expiremnented with both Fafnir and J.A.Prestwich engines to be fitted into one of the Triumph
The head is mounted in a “slipper” (or holder) positioned above the disk at 0.5-2.5 microns from the surface. When the disk is revolving around its axis, an air current creates a velocity gradient with the surface and air.
