First Land Vehicle to Exceed the Speed of Sound; averaged 763.04 mph
Although the origins of three-dimensional printing date back to the mid 19th century, and the first patent application for rapid prototyping technology was filed by Dr.
Aircraft engines, considered unreliable during the first 20 years of aviation due to their need for liquid-cooling, heavy weight and other inconsistencies, were given a revolutionary boost with the development of Pratt & Whitney’s R-1340 Wasp Radial Engine in 1925.
The oldest surviving rotary snowplow in the world
The Rainhill Trials were an important competition in the early d
When Robert G. LeTourneau started moving earth in 1919, he thought that land leveling should require only one man. In 1920, by installing a generator and electric motors, R.G. was able to control the scraper blade from the tractor seat while driving the tractor.
In June 1922, LeTourneau developed his “Mountain Mover” with a telescoping bowl. He incorporated a floor behind the cutting edge taken from his previous designs, and employed welding instead of riveting to save weight.
A number of major engineering feats required to complete the tasks for the mission at hand, which were later used in further projects
The Hughes Glomar Explorer was designed to complete the mission of lifting a 2,000-ton Soviet submarine 17,000 feet from the bottom of the Pacific Ocean.
The oldest and most comprehensive collection of photographic and cinematic technology
In 1888, George Eastman created the Kodak camera, the first camera designed to use roll film. The camera's simplicity and user friendly mechanism revolutionized amateur snapshot photography and in 1892, he founded the Eastman Kodak Company, in Rochester, New York.
The first funicular to employ a single, two-rail track along its entire length, with a short passing track.
The ABACUS II, designed and built by Texas Instruments, was the first practical automated production machine for the assembly of integrated circuits. Using heat and pressure, it bonded fine gold wire to microscopic contacts on the silicon chip and pin connections on the package.
This, the first Curtis vertical turbine built, was constructed by the General Electric Co. for the Newport & Fall River Street Railway Co. It operated in the Newport, R.I., generating station until June 1927. It was transferred to the Harding Street Station of the Indianapolis Power &…Read More
In 1899, during the earliest days of the automobile revolution, A. O. Smith developed a new, lightweight steel car frame. Within a few short years, he was selling these frames to a “who’s who” of car makers including Cadillac, Oldsmobile, and Ford. A. O. Smith’s son, Lloyd Raymond, carried on…Read More
This was a pioneering venture in mainline railroad electrification and was a proving ground for railroad electrification technology. It established single-phase alternating current as a technical and economical alternative to direct current. This concept exerted considerable influence over…Read More
During the 1930's, research into advanced ballistic measurement techniques began at Aberdeen Proving Ground—the world's first large-scale, fully-instrumented ballistic range producing data on the aerodynamic characteristics of missiles in free flight.
Although this research had begun…Read More
People thought inventor Walter Aiken was crazy when he proposed a railway to the top of Mt. Washington. Aiken built a model of the roadbed and track with a cog rail system, but entrepreneur Sylvester Marsh is credited for launching the Cog Railway and bringing Aiken's ideas to fruition.… Read More
This machine, which began operation on December 15, 1891, for the New York Edison Illuminating Company, represents the beginning of large-scale electric power generation in the United States. The generator was designed by chief engineer John Van Vleck, David Joy (known in England for his valve…Read More
This run-of-the-river plant is a typical example of late nineteenth-century small-scale (750 kilowatt) low-head hydroelectric power technology. The Fries Manufacturing and Power Company began operating the Idol's Station on April 18, 1898, making it the first commercial hydroelectric plant in…Read More
This low-head operating plant is representative of nineteenth-century hydropower-plant practice using many small turbines in contrast to twentieth-century use of few large turbines and generators. Its 40,000 horsepower capacity made it the largest in the country using turbines of American design…Read More
Only since 1912 have glass jars and bottles been in cheap and plentiful supply for pharmaceuticals, household products, food and beverages, and an endless variety of uses. The bottle-making machine introduced the safety, standardization, quality, and convenience of glass containers. Not only did…Read More
The largest mine hoist in the world, it serves the two incline skipways of Shaft No. 2, almost 9,300 feet long. The overhead winding drum has a diameter of 30 feet, of which the cylindrical center section is 10 feet long. The two 10-foot long end sections taper down to a 15-foot diameter. Wire…Read More
The Connecticut Light & Power Company pioneered the use of pumped storage in the United States at this hydroelectric station. First operated in 1929, the Rocky River Plant had two reversible pumps that somewhat resemble large hydroelectric turbines. This permitted significant improvements in…Read More
America's first practical helicopter, it pioneered the single main rotor concept that became the predominant helicopter configuration throughout the world. The principles that were developed and demonstrated by the VS-300 had direct application in the design of the early mass-production…Read More
The Wildcat's innovative "Sto-Wing" mechanism developed on the XF4F-4 prototype by Leroy (Roy) Grumman (1895-1982), a founder of Grumman Aircraft Engineering Corporation, was crucial to the U. S. Navy's success during World War II.
The idea of a folding wing was not new: as early as 1920…Read More
Developed for use in both the plains and mountains, this coal-fired passenger locomotive was among the most advanced in design, construction, and performance of any 4-8-4. Designed by Norfolk & Western engineers and built in the Norfolk & Western Roanoke shops, the 611 was specially…Read More
The 4,620-horsepower GG1 was primarily a passenger locomotive, routinely operating at over 100 miles per hour, but was used in freight service as well. Conceived by the Pennsylvania Railroad and built by the Baldwin Locomotive Works and General Electric Company, No. 4800 logged nearly 5 million…Read More
The articulated wheel-base steam locomotive represents the final phase of steam locomotive development in size and power. The cab-in-front feature was widely used by the Southern Pacific Railroad beginning in 1909 to alleviate smoke and heat problems for locomotive personnel en route through…Read More
The refrigeration units placed on trucks in 1938 by Thermo King Corp. revolutionized the transportation of perishable foods. Today they are a common sight on streets everywhere. Consumer demand for meat, poultry, produce and dairy products increased at an astounding rate. These installations and…Read More
The integration of pump and turbine was the first of many to be installed in power-plant systems in the United States. It was the largest and most powerful in the world.
