  • Intensive Development Of Rigid Airships
    1,175 words
    The History of The Airship Airships. In the early years of War, these beasts were known for their majestic presence in the sky and were icons of a country's power and prestige. They reigned mostly as reconnaissance and transport utility aircraft but there was something about this 'lighter-than-air's hip that made it far more than a mere utility workhorse. In this essay, I will discuss the ever-popular and ever-living king of the sky; the Airship. Airships, or dirigibles, were developed from the ...

  • Type Of Internal Combustion Engine
    1,488 words
    Internal Combustion Engines An internal-combustion engine is a heat engine that burns fuel and air inside a combustion chamber located within the engine proper. Simply stated, a heat engine is an engine that converts heat energy to mechanical energy. The internal- combustion engine should be distinguished from the external-combustion engine, for example, the steam engine and the Stirling engine, which burns fuel outside the prime mover, that is, the device that actually produces mechanical motio...
  • Developments Jet Engines
    654 words
    The Evolution of Jet Engines The jet engine is a complex propulsion device which draws in air by means of an intake, compresses it, heats it by means of an internal combustion engine, which when expelled it turns a turbine to produce thrust, resulting in a force sufficient enough to propel l the aircraft in the opposite direction (Morgan 67). When the jet engine was thought of back in the 1920's the world never thought it would become a reality, but by 1941 the first successful jet flight was fl...
  • Air Towards The Nozzle
    825 words
    Mixer The hot air that is forced out of the combustor and through the turbine continues to exit the engine at the rearward. Before exiting however, this air must be mixed with the cooler bypass air that did not go through the compressor and combustor. These two air streams are mixed in order to quiet the engine. To understand how air can create noise, first consider the way water splashes and makes noise when a wave crashes. In the same way, when two different air streams traveling at extremely ...
  • Jet Engine's Social Environment
    5,706 words
    The Jet Engine and the Revolution in Leisure Air Travel, 1960-1975 Peter L yth Air transport for European tourists got off to a shaky start in the late 1920's. 1 But it was to be thirty years before leisure air travel was to appeal to anyone but the rich and adventurous. High cost, fear of flying and the absence of toilets in early airliners (an unfortunate combination) were the main deterrents; the unpressurized aircraft of the inter-war years were noisy, slow and not especially comfortable des...

  • Air Foil
    1,512 words
    Aviation Benchmarks Thousands of people have contributed to Aviation. Dreams by the Wright Bothers made flight possible for all of us. Others like E melia Earnhardt, and Charles Limburg stretched the limits to accomplish what had never been done before. Many have even given their life to be in the air. I will discuss some of the paramount events and people that helped transcend Aviation. The most appropriate place to start is on the Seventeenth of December in 1903, the brothers Orville and Wilbe...
  • Rotary And Small Inline Engines
    1,060 words
    Aviation Powerplants Aviation has reshaped modern life and has provided for extreme convenience for traveling businessmen, vacationers, and thrill seekers alike. It also plays a key role in military operations of all kinds. Although aircraft design progression plays a predominant role in advancing speed, agility, utility, and entertainment; none of these would be possible without powerplant development, refinement and modification. Aviation powerplants originated with the Wright flyer and its sm...
  • Turbo Unit
    814 words
    How The Turbo Unit Works The Compressor Side To keep it brief and simple, a turbo unit compresses the intake of the engine by means of a fan. Essentially, the fan pulls in air on one side and then it pushes it out the other (see diagram A, here it's referred to as the compressor wheel). A fan performs the function of moving air; however we are still left with the task of compressing the air. In order to compress the air; we must then contain it within an enclosed space (this is the compressor ho...

  • Piston Less Steam Engine
    3,203 words
    Engine is a machine that converts heat energy to mechanical energy. In all conventional engines a hot gas expands within a cylinder, pushing a piston and that causes mechanical work. This straight-line motion is changed to rotary motion by a crankshaft connected to the piston. In external-combustion engines like the steam engine, the gas is heated by burning fuel outside the cylinder and enters the cylinder at a high temperature and high pressure. In expanding and moving the piston, the gas grow...
  • Two Piston Type Stirling Engine
    1,404 words
    The Stirling Engine Robert Stirling invented the Stirling engine in 1816. At the time he was a Scottish minister. Stirling engines were the safest engines made during that time period that would not explode like a steam engine could. The Stirling engine would not explode because the pressures could not be elevated to that to such a high level. The machine simply stopped when the heater section failed from thermal stress or imperfections in the material or manufacturing process. So from that day ...
  • Water Move
    792 words
    Everything is made up of elements Modern elements are less evocative but more numerous, they make up just over one hundred basic substances All things consist of particles called atoms The way molecules behave governs the workings of many machines, such as ships, airplanes, pumps, refrigerators, and combustion engines. Molecules of gases are so hyperactive that they will fill any space open to them In liquids, the molecules are less energetic and go haphazardly around in small groups In a solid,...

  • Engine With Compressed Air Power
    3,437 words
    Using an electric hybrid leads to a significant improvement in vehicle fuel economy. Unfortunately, it also leads to a substantial increase in cost. Regenerative compression braking offers another way to achieving the same objective without incurring the same cost penalty. With some modifications, the vehicle engine can perform both absorption and recovery of braking energy, using compressed air for energy storage. The process parallels the one employed by electric hybrids, but it requires none ...
  • Gas Turbine Engine
    4,207 words
    The idea of utilizing the physical principle of reaction on a large scale by means of rockets is usually attributed to China in the thirteenth century. Not until after the Second World War, however, did rocket technology mature to a state which made the idea of space travel a practical possibility, owing largely to a giant step forward during the war itself. Although earliest models of the steam turbine date back as early as the 17th century, practical applications of the turbine engine had to w...
